Removing an Old and Heavy Cast Iron Tub by Proven Helper

Cast iron tubs can weigh over 300lbs easily depending on the size, shape, and wall thickness, which makes them very difficult to remove. Depending on what your plans are for the tub, you have several different methods you can use to remove one. I've tried both methods in the past so I can help you prepare for what you're in store for.

 

Plumbing Preparation Prior to the Tub Removal

Cast-Iron-Tub-Plumbing-DiagramNo matter what method you choose from below, you will need to makes sure that you disconnect any plumbing running to the tub. Usually this entails disconnecting the drain waste and overflow pipes from the tub itself. Sometimes these are the only things keeping the tub in place due to the tubs weight alone.

You may also need to cut caulking around the tub using a utility knife, if the tub is located next to one or more tiled walls.

Sometimes a special tool called the "Tub Drain Remover" is required to unscrew the bottom drain from the tub's plumbing below. I typically used a massive screwdriver and wedged it into the slot in the upper portion of the tub drain, then unscrewed that drain strainer counterclockwise if my memory serves me right. The tub drain remover tool just makes it easier, you can pick one up for $10.

The tub overflow piece that's located inside the tub can usually be unscrewed with two Phillips head screws.

Okay, now that you properly disconnected the plumbing from the tub itself, as a safety precaution, you can turn off your water supply, just in case you accidentally damage a water pipe during the actual bathtub removal process.

Skip to the method that pertains to your actual needs, one is for people who plan to keep the tub in one piece, and the other is for people who rather remove the tub in smaller chunks.

 

 

Method 1

Remove a Cast Iron Tub in 1 Piece

You should have everything disconnected from the tub at this point, now you have to break loose the tub from the walls if that's how it's installed. You're going to have to do whatever it takes to remove it, this can entail removing wall tile, and other obstacles that can be holding the tub in place.

If you cut the silicone bead and still can't get the tub to budge, you may have to break the walls that hold the tub there. I would personally break as little of the all as possible if, you're plan is to retrofit a new tub in that area. If you're planning a major remodel, it may be a lot easier to remove the surrounding tile and cut the wall board off 6" above the tub, so that you can give yourself plenty of wiggle room to wedge the tub out of its cavity.

Sometimes people want to relocate or reuse an old cast iron tub and it is doable, but you're going to need some man power because of the sheer weight of the tub. I remember one of our first whole house remodels back in  2005, we removed a cast iron tub and had to carefully navigate it through the hallway and kitchen and then down the 2 flights of stairs. I remember that removal clearly because it was a bit of a nightmare. If you have to walk your tub down a flight of stairs, I recommend at least 2 strong guys at the bottom of the tub, because the weight is too much for one guy to bare all on his own. With this method you are going to risk damaging the stairs and any flooring you can possibly drop or drag the tub on. Also you may scrape or bump into walls, doors, and other obstacles on your way out of the house, so plan ahead and be careful.

 

Method 2

Break the Cast Iron Tub Into Pieces

I've used this method 3 times, 2 on the job for previous customers and once for myself. First make sure you've done the work mentioned previous regarding the plumbing disconnect . You can stuff some crumpled up newspapers into the exposed tub drain to prevent debris from clogging your drain pipes, that's what I did.


For this method I recommend the following materials:

1. Old comforter

2. 10 lb sledgehammer

3. Safety Glasses

4. Thick work gloves

5. Ear protection, because it's going to be very loud.

I removed both cast iron tubs by placing a blanket or old comforter over the areas I was planning to strike with the sledgehammer. Why use the blanket? The porcelain coating is going to shatter into tiny sharp pieces and they can cause injury if they hit your body. The comforter will prevent them or pieces of cast iron from flying at you or somebody else. I wouldn't even think of using a sledgehammer on a cast iron tub or sink without taking the right safety precautions.

Once you have yourself protected and ready for work, simply strike covered areas of the tub with the sledgehammer, paying attention to how much force you actually need to break pieces off. My particular tub took a ton of force, watch the YouTube Clip below to see me in action, I even show footage of what my new bathroom looks like after I converted the old outdated bathrooms into one larger bathroom instead. I think you're going to like what I did with it.

One last thing I want to point out is that the corner walls of the tub might require more force to strike but they are also great starting points in my opinion. Once you break the top corner of the tub, you can continue whacking pieces off the tub wall. Remove all the pieces that area easy to handle out of your way and keep working at it until the whole tub has been obliterated and removed from your bathroom.

For cleanup, I suggest a good shop vac, because you'll have hundreds if not thousands of porcelain shards and small pieces of cast iron as well to clean out from the floor.

 

Good luck, and please be careful. If you don't trust yourself doing a job like this, hire somebody how has experience.

 

How to Deal With a Computer Virus Like a Techie

How to remove a computer virus like techie. A list of the steps a techie would take to get rid of a virus.As someone who's been figuring out computers and all the trouble they get into for more than 20 years now, people constantly ask me questions. This time a person contacted me on my Proven Helper Facebook page regarding a virus he got by downloading torrents from the internet. Below you will find his question and my response. I hope that it helps other people out there who downloaded a virus somehow, or opened up an attachment in an email that later infected their PC.

And don't be fooled by the media, all computers including Mac's, Smartphones, and even your car computer can get viruses. Just remember that a virus is simply a program written by a prankster, hacker, or enemy who wants to fool with you, ruin your day, or extort money from you. It doesn't matter what computer you use, there's a techie out there that knows, tested, and continues to create new viruses for it. That's the unfortunate truth, now lets get to what was asked, and my email back to the fan of the SelfMade Life YouTube Channel.

 

QUESTION: Hello. I read the information you've put in your videos and I'm glad to know that you're welcome to answer the questions. I've got this problem 2 days ago. Everything began with downloading IDM by torrent. after that lots of viruses occupied my system. I think they are rstray.exe and ravmon.exe Chinese programs. Before I downloaded the torrent everything was ok. Whatever I try to do something on my computer, It just doesn't work. If I want to change permissions, I get access denied. If I want to end a process by using task manager, it doesn't work. Even if I want to delete a file, it won’t let me delete.

I'm totally confused about how to get rid of this virus and get my computer to work like it used to. I’d like some advice on what to do about this horrible virus. Thank you!

 

Top 10 Tips on How To Remove a Computer Virus 

    1. First I want you to know that every computer geek out there knows that if a virus is really bad, nothing is safe unless you reinstall your Windows operating system from scratch. But you can leave this as a last resort option for now.
    2. When a computer virus prevents you from deleting files, changing permission, and ending a process, you can try to bypass its activation by booting into Windows safe mode. Simply restart your computer and press F6 before the Windows logo pops up. You might have to try this process repeatedly until Windows asks you if you want to boot into safe mode.
    3. However, these hackers don't make it easy to removal a virus. Sometimes the virus renames itself as a known process. If that happens you would have to get the file size and date of the affected file, and compare it with the one on your computer. This can get complicated because there could be many known legitimate revisions of that file program, so you would have to know exactly which version you have before you start suspecting. Sometimes the file size is different by a huge margin, making it easy to find the suspicious program. But other times these hackers can even get the file size down to the bit, so even this method is not full proof.
    4. The bottom line is that if you really want to beat this virus you're going to need another computer to Google your questions while you keep looking for signs of the virus. Google strange activities your computer is doing, Google strange processes in your Windows Task Manager, and Googling error messages are just some of the things I’ve done in the past to figure out what computer virus I have and what can be done to remove it. Chances are someone else out there already caught the virus and wrote how they removed it somewhere.

 




  1. Also newer virus's change names, so you can delete one, and then another one would spawn in a different name in its place. You can track your active processes and see what happens when you kill a process.  If something is respawning a process either as the same name or a completely different name every time, you have to find the Windows Process or Service that is running which is therefore allowing this entire process to happen. Check Msconfig in older versions of Windows by running the command Msconfig. Shortcut is Window Key + R this will bring up the Run prompt, then type Msconfig. In Windows 10, the startup section has been moved to Task Manager but you can still execute this procedure, then click the blue link that says open task manager. Alternatively, right click the Windows Icon, then Task Manager, then Startup. The Services Tab in Windows 10 is where you can examine Windows Services that can be running and turning on your virus every time you boot into Windows.
  2. Many antivirus programs have rootkit removal tools or virus scanners that can be installed on a USB stick that you can run to help you catch the virus. This of course assumes that this is a known virus and not something new which won't be caught. You can also download Rootkit Removal Tools from trusted websites. Also sometimes specific virus removal tools are created for specific viruses. In this case, you will have to figure out exactly what virus you have by doing some of the work noted above.
  3. Sometimes a computer virus just ruins one user profile on the machine. In this scenario simply create another user profile, then transfer over just the documents or photos you need. Then delete the corrupted or infected profile.
  4. I’ve seen viruses disable and imitate antivirus software before. Remember, the people creating these things are just human, so sometimes you can almost predict what they might do, to fool you into thinking that everything is okay. Think outside the box or meditate on what to do for 15 minutes and see if your subconscious can drop some hints on what to do next. You’d be surprised how helpful meditation can be for solving any type of problem.
  5. This is another technique out of left field, but I have been using it to my advantage for more than 20 years. It’s the set your mind on that you’re going to solve this problem and that’s that solution. Our brains our powerful tools that sometimes we don’t exercise enough. I learned about this power of setting my mind on solving a problem long ago, when computers used to cost $2,500 and if something broke it was going to be an arm and a leg. So when things went wrong, which they also do with computers, the first thing I said to myself was that somehow, someway, I was going to figure out this problem. And interestingly enough I became so good at it, that I worked in IT for more than 10 years once I grew up and even in my IT days I used the advice I wrote on this post to solve 99% of my computer problems, no matter if it was a virus, worm, bad hardware, or bad software. These techniques will work, but you have to have the patience and will to make them work for you. Sometimes you can beat the problem quickly, while other times it can take forever. Which brings me to my final tip.
  6. If you don’t want to reinstall Windows, try any of these steps, or simply don’t have the time to find and remove this virus on your own, despite how awesome you will feel afterwards. You can always bring it to BestBuy Geek Squad or some other shop and have them use these techniques for you in exchange for a fee. Sometimes they just choose the easiest method, because no one is going to spend hours when you’re only paying them $50. You get what you pay for,

 

 

Well I hope you enjoyed learning about how I removed my computer viruses in the past and even used these principals to build a career in IT. I still use these principals to this day and believe in them 100%. A computer Virus is written by humans and every human has a weakness. You simply have to find out where this person was lazy and remove their electronic prank from your computer.

Real Answer to Is a House on a Dead End Street Bad Feng Shui

 

Looking for a new home to buy can be more of a project and risk than most of us think it is. I can honestly say that the process can feel grueling and never-ending, because buying a house is much like getting married. You have to lock in all the qualities you really can't live without and figure out which qualities you're willing to overlook, because a house much like a spouse will never be perfect and neither will be the process of finding them. In the end you still have to hunker down with faith and put your money on the one you think is the one and hope for the best. There are no guarantees in life, just educated guesses, ancient wisdom like Feng Shui and statistics.

Will This House Make Me Happy?

Do you need quick answers on how much typical home improvement projects cost, because your buying a home this year? If you are in the market to buy a new home this year, you're probably driving around town with your Samsung Galaxy, iPhone or iPad with Zillow or another mobile app, scouring the neighborhoods for good deals.

Maybe you've gone to the next step and signed a contract with a Realtor like we did. I say we because my wife and I have been looking for a 3 bedroom home for the past couple of months now, but almost every home we visit, we find ourselves asking things like "How much will it cost to remodel the bathroom", or "Do you think we can do the windows, roof, and kitchen remodel and stay within budget?". Yes folks, even a former general contractor does the same thing you do, when they shop for a home.

From siding replacement, to bedroom additions, and even adding on a garage, all of us are driving around town or searching for houses feverishly on our mobile phones, tablets and computers, thinking "Can I afford to make this home into the home I really want?". (Browse my typical home improvement costs chart; includes job costs for 35 projects.)

I'm a retired general contractor but the retired part is not so much by personal choice. The recession thanks to good old George Bush junior and a few other circumstances beyond my control, forced me to close down a business that I poured every single dollar and a whole lot of energy into. It really was a catastrophic life experience, complete with a financial disaster and an infamous health problem that could have easily snuffed me out during the last few stressful months I held that company with my Kung Fu Grip, while I desperately tried everything to save it. 

 

Important Lessons Learned from a Catastrophic Life Experience

Lesson One: Don't put your personal life on hold while you're trying to build a nest-egg, because there's a chance you will run out of time like I did. I practically put off dating for 6 years while I was working my butt off on my business, and when my business forced me to go bankrupt, I realized that choosing to focus purely on the business was a big waste of time. 

One month after I closed the doors to my business for good, I was dating again! Several months after that, I married an amazing girl from Sri Lanka, who also went through her own catastrophe, which I believe molded her into the amazing person she is today. I actually believe based on my personal experiences and by the experiences of others that huge catastrophes in life force a person to mature past their age. I'm happy to report that I'm truly happily married to my wife Kawshi, but maybe I paid the price for this happiness. What do you think? (Actually keep reading, it get's really interesting ahead)

Lesson Two: Sometimes our biggest failure leads us to the beginning of our biggest victory, as long as we focus on the positive in the midst and aftermath of a disaster. Closing down a business you spent countless hours on is exactly how you would imagine it to be, painful and depressing, and for me it was extra painful.

I have birth defect that produces superhuman levels of pain called pancreatitis. The sickness is caused by stress even though modern medicine has not confirmed this. I've written a lot about that on my other websites, because I've made remarkable progress in controlling it in my life. However when my business was drowning in debt, my pancreatitis flare-ups were torturing me every week instead of every month and that started to worry me. I manifested some highly unusual experiences fighting this health condition and on several occasions I completely bewildered my doctors. After that, I became a huge supporter of mind over matter development, which is also known as using the power of your subconscious  mind. To most this type of power is fictional but when your life depends on it and you causephysiological changes within your body that doctors can't explain, you tend to develop  a faith in these types of things. However fighting through a crushing defeat like a business closure that you poured your heart and soul into was far more challenging for me to keep my mental composure on and towards the end there, I found my faith wavering in  my ability to get through the situation unscathed, or even alive.

Eventually I realized that because of circumstances beyond my control, I could stick around and watch a business that I've worked hard to make amazing and award winning go down in ruins or I could admit defeat and move on with my life. The fact that you're reading this right now, is a clear example of the path I chose. Right at the 11th hour I decided that my life was more important than fighting the inevitable, because it's not like I could make the banks grant $100,000 renovation loans to my customers who couldn't get approved after lending practices were changed. It was time for a reinventing of myself once again, something that I've done more than a few times in my 35 years of life!

 

Did the Feng Shui Dead End Street Curse Kill My Business?

Did I mention that my business office was located on a cul-de-sac, often refereed to as a dead end street? I acquired the office back in 2007 and I already knew about the dead end street significance in Feng Shui texts that says that the energy can be chaotic, stagnant, or low because it's divided among all the other properties on the cul-de-sac. We got a great deal on the rent from my business partners dad who owned the building with his partner, and we thought it would be okay. However I lost my business and my business partners dad was victimized by his business partner who stole over $100,000 from the company account. Sure it may all be a giant coincidence, or maybe there maybe something to this Feng Shui wisdom.

Feng Shui Cured Office (Dead End Street)

Putting the Nail in the Coffin

When we were furnishing the office, we went to a going out of business sale at a large office building and picked up several desks for the office, 2 old and 1 new. Turns out that Feng Shui texts also talk about the possibilities of facing the same faith as the previous business, if you acquire their place or belongings. Strike 2 indeed!

Because I did know a bit about Feng Shui, I employed several cures just in-case there was something to this mysterious 6,000 year old wisdom. Look at this picture of my old office. In the upper left corner I setup a Feng Shui water fountain and a lush plant filled green space in what's considered the wealth area. Our business always wasn't doomed you know, we grossed 1 million dollars in a little over a 14 month period right before the recession hit. And I've won so many awards for the business from the Better Business Bureau year after year that they actually asked me not to apply for next years award because it wouldn't be fair and others would think the contest is rigged. LOL, true story!

 

My Phoenix Like Resurrection

So I put the past behind me, decided to start fresh and rebuild my life from a financial disaster that might have been caused or helped by the dead end street Feng Shui Curse. I once again find myself in the market to buy a new home.

Now I'm saying a new home, but the fact of the matter is that I'm a newbie in the field of purely working from home by writing articles and producing Youtube videos out of all things. So the house my wife and I are looking for will be relatively new instead. Good ole Google and YouTube have to bless me with a few extra thousand bucks in my monthly paychecks, before we can buy or build that shiny new house we really want, but I digress.

 

Oprah Went To School Here

We are currently looking for a newer home. Just today we had our hopes shattered once again, when we set them so high to look at a very promising 3 bedroom raised ranch in a very appealing neighborhood. The house was just listed and no photos were provided on Zillow, Trulia, or anything else; just one measly Google Streetview photo. But what was provided was the fact that this particular home was right on the town line, between a town that's A-okay, and another town that is just plain great, but generally above our current price range.

By great town, I mean low taxes and some of the absolute best quality schools in Connecticut (Have you ever heard of Oprah? I thought you might, she actually went to one of these schools!) . We were excited beyond reason for the showing and I even drove down there while my wife was at work, to text her a few photos because she couldn't wait to go see it herself.

That's one of the benefits of working from home, I can leave the house whenever I please you know, but to be honest I find myself constantly working on my business because my goals are larger than life and my thirst for fancy cars is never going to be quenched in entirety like Jay Lenos. Speaking about making money from home, have you seen this lovely ad before :) 

 

 

 

Giving a Dead End Street A Second Look

 

So long story short, we let ourselves get excited once again, and today at 9am we met with our Realtor at the house that was said to be in need of a little TLC . Now mind you we are not morning people, so to meet our Realtor on the weekend at 9am, was a slight exertion of effort on our part. Anyways, we get to the house and pull into the crackled driveway. Then the nit picking begins, as we wait for our real-estate agent to pull up.

"Look at the siding, it's dirty, look at the garage door, the paint is peeling", "Why are all the bushes dying?". As we waited, we just kept noticing small imperfections with the house on the quiet cul-de-sac and then our real- estate agent pulled up in her slick and silver Mercedes. Now the inspection of the house we were ready to put a full price offer on, because of the location and taxes, begins.

Oh my God! WTF! Were my first thoughts. Pardon my acronyms, but this guy was the biggest pig ever! I say guy because I did a little Google espionage the day before on the house and found out that the owner is in his mid 40's, and he's been living there for about 11 years. First the carpet was so far beyond the original color, we had no idea what the original color was. Then we saw his ugly black fireplace surround! I mean who paints their outdated fireplace surround bricks gloss black! And I'm not talking about someone who made a contemporary looking fireplace surround, nope. We're talking about someone who drank a 12 pack of Miller Light and thought he's a Picasso with a black spray paint can, type of fireplace. 

So besides the dirtiest ceilings we ever saw, soot on the walls and ceiling form the pellet stove. There was massive spiderwebs on the ceiling corners, 45 electric guitars in every room, and 8 cases of Miller Light beer in the bathroom. This house was in need of everything. We're talking about all new flooring, paint everywhere,new kitchen, new bathrooms, new windows, new doors, new HVAC system, pretty much a complete new interior. Yeah, our heart sank within seconds of the showing. This house is the definition of what can go wrong while living on a dead end street. He's in his forties, the house is dirty and broken everywhere, and he doesn't seem to be married, because what women would dare to eat or sleep in a cold, dark, dingy, dungeon?. 

 

Rock & Roll Should be on the Radio

Can you imagine setting yourself up thinking this house might be the one, then walking into Ozzy Osborne's bachelor pad from hell? Yeah, within 30 seconds of viewing this dead end street house, we knew right away there's no way in hell we'll put in a full price offer on it, EVER. Hell, the house probably needs at least $30,000 in repairs alone (It had a roof leak too), not to mention things we would want to upgrade there like the heating system, kitchen, and bathrooms. Plus, how much is an exorcism anyway? We don't think it's haunted, but it sure doesn't look like it's not haunted, and it is located on a Dead End Street!

 

Is A House on a Dead End Street Bad Feng Shui? YES!!!

Dead End StreetI can't say that I'm a Feng Shui Guru, but ever since I read a few books about it, I cannot help but notice that I see similarities between what the books say, and what actually happens in real life, either to me or other people I know. I'm not superstitious, but if something seems to be happening to the occupant of a house and the Feng Shui principals I memorized pretty much spell out the persons circumstances, it may be a good idea to learn what not to do at the very minimum, right?

You're not going to catch me hanging wooden flutes above a doorway, but you may find me not facing my bed towards the bedroom door, which is considered the Feng Shui death position!

Hey we live in an amazing universe and no one exists that really knows all the rules. Many have tried to explain how the universe works in entirety like Albert Einstein, and some are still trying to create the theory of everything like Mr. Steven Hawking. All I know is that I tend to follow the wisdom of whatever worked in my life so far, and what seems to work in the lives of others on average. On that note, please visualize me being the first trillionaire who dedicates mas fortunes to improving all of our lives :) Hey, it was worth as shot wasn't it?

There's a 90% Chance Your Central AC System Is Installed Wrong, Sad But True

b2ap3_thumbnail_bad-central-air-conditioning-installation.jpgDid you know that about 50% of all the money we spend on heating and cooling is due to inefficiencies in the way these systems are installed?

It's a sad but true fact. A whopping 25% of your hard earned money is literally leaking out of the duct work. The other 25% comes from other installation problems with the units themselves.

The biggest problem according to John Proctor of Proctor Engineering Group is that the vast majority of heating and cooling systems are improperly installed to being with. A poor installation leads to wasted energy, future reliability problems with the units themselves, and of course a whole lot of wasted money. 

 

The good news is that there are several things that any homeowner can do to begin the auditing process of their HVAC system. Just keep in mind that for some of these steps, you are better off printing out the article and discussing it with a licensed heating and air conditioning contractor. You can find a HVAC contractor using the form below, or using trusted sources like the Better Business Bureau. 

 

Have a licensed professional check your HVAC system for energy efficiency by verifying the original installation. John Proctor has found that items like the compressor, coil, and capacitor will last much longer when compared to exactly the same HVAC systems that were installed by a lazy or incompetent HVAC contractors.

 

Did you know that about 50% of the money you spend on cooling your home is being wasted because of a improper installation?

Standard Installation - Not Good Enough

  • setting the outside unit
  • bringing the set of lines out
  • brazing it together
  • opening the valves
  • turning it on
  • and testing for cold air operation
  • this doesn't cut it

Proper A/C Installation

  1. Match outside unit and inside coil
  2. Braise the lines using nitrogen. So when you flow nitrogen through it you won't get little carbon pieces of carbon; they will end up clogging the unit and making it not work right.
  3. Evacuate inside coil & line before refrigerant. You need to use a vacuum pump, a micron gauge, you have to pull all the moisture and air out of those lines and the inside coil before you put the refrigerant in.
  4. Release the refrigerant into the inside coil & the lines, and then you have to check and make sure you have the right amount. Because it comes with a certain amount but it is not the right amount necessarily for your inside coil and the length of lines you actually have. You usually have to add enough refrigerant to get it up to the right amount of refrigerant in order to have the unit run at its top efficiency.
  5. When you don't evacuate the system, because what you end up with is air and moisture in the system. Decreases durability because the excess moisture will turn into acid and corrode the system.
  6. When you don't have the right amount of refrigerant in the system. You will have too much super heat which means the compressor will overheat and burnout. If you have too much refrigerant it's going to slug liquid back to the compressor and ruin the compressor that way.
  7. When you have low airflow accross the inside coil.

Duct Work

Having leaky duct work system with a seer 14 AC unit will easily drop it down to a seer 10 efficiency. Then if you add the wrong amount of refrigerant in, the efficiency will drop to a seer 8. And lastly if you get the wrong amount of airflow, you're going to drop it down to a seer 7.

Air Flow

The amount of air flow across the inside coil.

4 ton air handler on a tiny duct system equals not enough air flow.

You really need to test it.

Test Method 1: Temperature Split Method

Title 24 Airflow Test in California has a temperature split method which is a common method that is easy to do. What you do is measure the wet bulb and dry bulb temperatures which tells you what the humidity is as well as the temperature on the return side. And also what the temperature is on the supply side. So you see how much the temperatures drop between the return and the supply. Based on the temperature drop you can tell whether or not you got too little air flow or not.

You can compare your results with a table you get from the CDC website www.energyu.ca.gov. It's good for all the states, east coast, Saudi Arabia. If your temperature split is too high, you got too little airflow.

Test Method 2: Using a Flow Grid

This is the best way to measure the airflow. Its a device that you put in where the filter would normally be and you take a few pressure readings, and from that you can get real accurate measurements of how much airflow is flowing through the inside coil.

How do you know if you have the proper amount of airflow. Manufacturers give different specs for different regions to get air flow numbers. 450 cfm per ton across the coil in  California.  Georgia where it's hot and humid needs 350 cfm across the coil per ton.

What About The Size Of The Line Set Itself

As the line set gets longer you have to change the diameter of the line set. It's something that the manufacturers specify but it's most often ignored. Most often mistakes found coming from the back of the unit they will actually use a smaller line set which the machine was designed for. People actually take clamps and squeeze down the unit not put a fitting in there and braze the gap. The efficiency drops significantly using that method because there's a good pressure drop there andnothing is working right at that point.

Top Efficiency Hits

The Durability of a system depends on doing it right. If you don't do it right the first time, it's going to keep coming back and bite you.

Checking Contractors

  1. Make sure they know what the specifications are. Then you need someway to have that information verified by a third-party. The CDC has a way The CheckMe System. www.proctoreng.com
  2. While the technician is still on the site they gather the information and pickup the cell phone and call a toll free number, the numbers are read over the phone. It goes into a computer program that checks everything and makes sure its a good test. And since the technician is on the site, they verify that the airflow is right and that the charge is right. Also if there is a problem, the technician can address it right away. This system helps everybody.

This helps out the builder, state, and HVAC contractor. Good trade schools and manufacturers have training.
