Doing a proper vacuum and pressure test is one of the biggest install issues. Lots of installers do not do them properly if at all. The company I worked for hired an installer the manager loved because he would install units is 2 hours. They would pay him for a full day no matter how long he worked for the day. Got lots of call backs from units that he installed.

[@jmead6121]

Ill bet 2 hrs is time to unload the truck & clean up after lol I dont use sub crews that can & do 2 / 3 complete change outs per day ..always call backs ..1 per day is plenty .dont drag the job out of course but do it all right the 1 st time & hardly ever an call back ..Right ??

Angry. Pissed. Mad.. Bought new Trane last summer. Company from Clinton Township MI installed. We called 2 days after install to complain about run time of unit and poor cooling. Same tech came out and said "low on refrigerate". WTF, just got installed. Just had checkup on unit done. Pressure 73. I demanded new unit and new install. Owner, coming this week to do. I'm a nurse. Yup, female. Just ask yourselves this HVAC guys: what would happen if I did my job as sloppy as most HVAC guys. You die, just as my new unit. I check and double check and have pride in providing excellent care for my patients. Do better!

[@mealworms19]

I'm HVAC tech, male , and I'm not perfect like female nurses. I make mistakes. I had a few jobs where everything turned out great but had evap coils leak oil so overtime the unit gets low. That's not something I would catch on the initial day of installation. As long as the company finds the problem and gets it fixed no need to be overdramatic.

I just had a new 5 ton system installed, cost $13,500. After they were done, I asked for the manual. The installer said there wasn't one. I went outside and rummaged through all the boxes and debris and found the manual still in its plastic wrap thrown out with the garbage. The installer also mounted the new thermostat to the wall crooked.

[@HeatGeek1]

Yep. Just remember-you picked them.

[@drewsbenmad]

The problem is the customer expects miracles from the technician giving them one day to install a whole system regardless of whether there was existing issues with the old system. The line set and ductwork are often reused because it’s expensive to replace them and time consuming. But these two items are also some of the biggest problems so your new system will suffer if they don’t replace them. I would at least flush the line set and check the ductwork for proper sizing and leaks.

[@NewHVACGuide]

All good points. Fast may not always be right.

[@Garth2011]

Contractors are just as guilty if they allow a customer to tell them how to do the work. As long as it is all explained as to the risks involved in cutting corners and as long as the contractor isn't exposing themselves to liability and writes down what they suggest but customer declines, in writing, then you can always go back and point of the facts, "customer declined this or that". In many cases, its probably best to not take the job if a customer is cutting a bunch of corners and the performance is sacrificed giving the HVAC contractor a bad reputation. I'd say those jobs are not worth it if you are in business for the long run. Large HVAC companies who send out "salesmen" to do replacement quotes are also guilty of the same when it comes to allowing a customer to dictate a job. All they want to do is get a sale which in the long run turns sour plus, so much for all of the benefits we are supposed to be getting with the "new efficient" equipment. I've been there...I've walked away from folks who won't take the minimum professional advice and I have no regrets. There's a limit. Most 1 day replacements aren't done that well anyway...likely those have lots of issues.

I paid for a new system and broke down with in 7 months 😢. Must of the things that need to be done were ignored. You are 100% right.

[@elginmercado5082]

Exactly! That’s why I bought and installed my own system. So far it’s been working like a charm. HVAC is overrated! Between $9,000 and $15,000 for a system. It’s ridiculous! And then it works for 7 months like your case and you are hosed. You need an HVAC Tech to tell you something you can research on your own. I did all the calculations including a load calculation, come to find out that my system was undersized. So I upgraded from a 3 to 4 ton and it solved my upstairs room issue where the rooms were always warm and my old unit would run constantly. I installed new line set, Trane furnace, coil, and AC for under $6,100 including a couple of tools. It ain’t rocket science, just do some research and go for it!

[@andysmith434]

​@@elginmercado5082 what were the couple of tools you had to buy? I hope you don't expect a company to do an install for what you paid for the unit. Nobody is gonna work for free. Did you pump the unit down to at least 500 microns? I do hope your unit works great and last though

[@elginmercado5082]

@@andysmith434 Hello sir, the tools I bought were: 1. Pipe bending tool, 2. Vacuum pump, 3. DIY guy recommended MICRON gage, 4. Staybrite 8, 5. Metal cutting shears, and a set of HVAC gages. No, I don’t expect for a company to do an install for the unit cost, but I also don’t expect to pay four grand above its price for the install. These folks what to charge like they are brain surgeons for something that is not difficult at all. I installed new lines because load calculations etc. called for a 4 ton unit. Old lines were too small and 30+ years old. Yes, the new lines were pressure tested and a proper vacuum was done reaching 500 and below. BTW, I used staybrite 8 for all the welds. I also had an issue with my upstairs rooms, always Luke warm, now it’s cold. Cold enough that blankets are required. Also, when I removed my old unit, I discovered that whoever did the install caped part of the indoor coil. The plenum should have been at 21” wide to accommodate the unit. Instead they capped 3” on top of the coil and left the plenum at 17” wide. From the outside it resembled a bell shape. However, once taken apart you could see the crap job they did. Any way, when it was all done I ended up spending $6,290.17. Better than paying $9,000 just for a DUCANE system - never heard of them - and lining the pockets of these HVAC folks. I have a new TRANE furnace, AC unit and indoor coil, new lines, all rated a 4 TON, some very cool tools that I didn’t have, oh and an extra 21lbs of R410A because I did manage to buy a container. It’s my opinion that install prices are inflated based on HVAC techs claiming it’s complicated. Thanks to the DIY HVAC Guy and his videos the process is explained and shows how simple it is. You just have to follow the NIKE slogan, Just do it!

I live in PA. Compressor went on a 6 year old condenser with only 4 years of regular use. My builder hadn't turned in the warranty. Paid the first guy for the diagnosis. Sales guy called and gave me an estimate on a new system. I asked for other numbers, replacing just the condenser, etc... Sky high, no matter my choices So I paid another guy to diagnose the same fried compressor, and his sales guy came to my home to give me an estimate on a new system. Got the name of another guy from a person who knows him, but has little knowledge of his work, and I paid him to come out. He seems honest, much older. His prices were significantly less, and he wasn't hell bent on selling me a new system, but still, I worry because nobody did any load calculations, and when I asked the older guy if he used Manual J and Manual D (I think?), he seemed insulted, told me he wasn't going to teach me the trade, has a degree in engineering or whatever. Frankly, as I sit here running my emergency heat, I don't trust anybody, but can't keep paying techs and then their salesmen to come to my home. What I'm really after here is a warranty, or I would just get the compresser replaced. I swear these salesmen come out to the home to see what you have. One of these salesmen is being high pressure on a special they're running. That salesmen had taken over for a guy who had been let go and is throwing astronomical numbers at me for anything less than a system that are different from what the other guy had said. $8k for a condenser unit to be replaced? $2k for a duct cleaning? He wasn't even going to honor the special. Better hurry and buy this week or next because that special expires. It was a Thanksgiving special. What? No Christmas special? To finance, it'll take 10 years to pay off, and by then they'll be trying to sell me a new system with yet a newer refrigerant. They put the fear in me there, that they might not be able to get the refrigerant I have on my current system, which I believe is 410A. Bottom line, I don't trust any of these fools. I think it would be cheaper to just throw sticks on my floor and light a match, let the house burn down, and hire a reputable builder to do the job next time, one who will submit warranties at least.

[@gregorysuarez7978]

POE oil is hygroscopic which basically a moisture sponge. As long as the line set is properly sized and leak-free, a good RX-11 Flush can clean out the residual mineral oil sufficiently. Moisture & heat = acid formation in a refrigeration system regardless of lubricant.

[@hansmuth6029]

👍👍👍 Every topic mentioned is bang on point. I'm a novice at this. I very much like to educate myself regarding the "mechanical" systems within my home. This video is the first one online that covers everything that is required for a quality install/repair. Regarding the "air handling" point here, wow! How many in this trade don't use a manometer? It's baffling. The absolute most important "spec" on your furnace = TESP! - How do you know if your HVAC was ever tested for static pressure? - look at your furnace. If you have small plastic/rubber plugs (1/4"-3/8") on each side of your blower, your unit was tested! Note: TESP for your furnace is measured on the unit itself. Basically, after filter (in blower compartment) and the top of your unit where the furnace transitions to your ducting. If your #'s are out of range of the spec'd rating of your unit, good luck trying to get the correct #'s re: heat rise/cooling drop temp you should have. (and the snowball effect re: gas pressure/coolant pressure for your system to work efficiently the way it was designed to) Found this to be very informative!

[@carlmccoy662]

In the manual: very important to put drip tray and air deflectors in correct position or take it out, depending on orientation of the air handler. Seems like most the units I take out missed that page in the instruction manual.

[@GuitarPlayer42]

Exactly this. On my third round of cleaning an absolutely filthy evaporator coil I noticed that an interior baffle wasn't removed during installation. Thus there was even more crud trapped behind that panel. After a quick check of the manual I was able to remove that panel, which not only increased airflow to the coil (which was the original purpose), but finally allowed me to clean that area and make some significant progress in air quality.

[@NewHVACGuide]

I remember calling a supplier and asking for a downflow kit, the instructions pointed out. He said he had sold hundreds of that unit to different contractors and no one had ever asked for one.

Home owner here, thought I had done my homework, obviously missed this video. Thought I would splurge and get the Mercedes Benz set up, duel fuel, multi stage, blah, blah, blah. I’m embarrassed to say how much I paid. After 1 year, fan motor fried, took over a month to get a new one, uneven temp for different rooms, they didn’t install dampers, and noticing an excessive use of foil tape, my fan has only one speed and all they care about is signing me up their “MVP Maintenance “ plan. Feeling like fool right now. I would add #6 to your list, more complicated and expensive is not always better.

[@davidsharkey3483]

I agree, companies have people installing before they can spell air conditioning. I still maintain the biggest problem is lack of proper training.

[@lightfusegetaway]

It's pretty bad when 3 out of 4 AC companies don't even do a Manual J let alone a load calc. That was my recent experience. And the one that did the Manual J was a bit half-hearted about it. They all ended up saying 4 ton, so I went with the lowest bidder with the longest track record and the best reviews. Overall happy with my Carrier heat pump package unit, plus got the $2k tax credit.

Thanks for the great care and going the extra miles to do the right thing for the right reasons. I imagine you could never do enough research or enough details. Bit it's great that you are open to trying and working hard at it. Even though many people do not have the time to appreciate that care and developed skill level

[@silvertbird1]

Good info. The AC tech I finally hired seemed very competent and has good reviews (selected in part because he's local, and I thought he would be more involved, but he met his crew and then left during the install), but he only recently started his company and may be overwhelmed with all the new work and trying to do so much himself. He wanted to install a 4 ton but a larger company quoted for a 3 ton. In the end, I had him put back a 3.5 ton and it is short cycling all the time. He installed a hard start kit on the new compressor, but now I'm wondering if that may cause problems in the long run. It's so frustrating to try and make the best decisions when spending $9000 for a new system, yet not convinced the system was installed correctly. And how can I really know at this point?

[@nd3498]

How are you going to inspect all of the ductwork to make sure it’s sized properly when the house is finished and the basement is finished with the old equipment sitting in a small unfinished equipment room? That needs to be done when the house is being built and most building contractors always take the cheapest route and cut corners. 99% of the homes we work in are between 20-100 years old and the ductwork is what it is because most customers are not going to right me a blank check to do major ductwork modifications to fix potential issues. I believe all the points mentioned in the video are valid and true but it needs to be directed at new construction home builders and installers also. The rest of us have to work with what’s already existing and most of the time it’s a shit sandwich with a customer who has a limited budget. I liked the video, keep up the good work.

[@Musictroper76]

I was going to say the same. It is easy to do all of this, when one has an unlimited budget. Most want the cheapest possible and when you come to them with a 15K price tag, they will find their brother in law who will do it for 5K

I had to get moving with hvac install so i ended up with what was the best at the time. Annoying for me was them sending out a sales guy, just for them to have to send out a tech for me to re-ask questions. Removed all old duct and unit. Within a year the evap coil got a pin leak in it. I had unf steped out, so i missed the vac and charge process. As a homeowner you trust that the pro will do the job acurately and with quality. I had the load calc done prior to estimates. Many would never ask, many more would take a copy just out of courtesy. Or look at it and tell me it was to small still.

My package unit downstairs was installed-i think it might have been 3 years ago. It has had issues since. Last 2 years it has had leaks in the copper tubing from vibration. That's what i was told. The guy that installed it owns a long standing company but he didn't show up this year when he said he would and we had already been a week without air. I called another company that came right out. The installation of both units leaves much to be desired. Duct work was never changed or mentioned, and one of the units was an old commercial unit estimated to be 25-30 years old. We're in a rural town and its hard to find anyone who does their job properly.

I set the temperature to 75°F, and it cools the house to the desired temperature before turning off. After about 5 or 10 minutes, it turns back on, runs for 10 to 15 minutes, and then turns off again. This cycle repeats every 5 to 10 minutes. I've checked the condensation line and ductwork, and everything seems fine. I also replaced the thermostat with a smart thermostat to monitor its activity. I’ve checked the following components, and there are no issues: • Compressor • Drain line • Ductwork • Thermostat (replaced with a smart thermostat) • Return air What could be wrong with the system? Is it normal for an AC unit to operate like this? My primary concern is the high electricity bills each month due to this issue. Also, I'm worried that the unit might wear out quickly, leading to bigger problems down the road. Any suggestions would be greatly appreciated.

I had same issue, tech guys replaced electronic board right outside the fan. It is working properly now.

Glad I’m just a supermarket refrigeration service tech lol

[@arkrainflood]

i had an hvac rep working up a quote for my house, said that the duct work was TOO LARGE ! and said it had to be downsized......nope.

[@NewHVACGuide]

that would definitely be outside the norm. Get a second opinion!

[@kindervelt2005]

If the existing system is working well and is properly sized, most of the calculations are not needed when replacing system.

How is all this moisture being introduced in a new system with new condensing unit , coil, line set and new drier?

[@NewHVACGuide]

Ambient air has humidity and moisture

[@mainj54]

@@NewHVACGuide With a evacuation it will boil off any moisture that will be in the small amount of air that is introduced upon installation even if it not triple evacuated.

I was watching some other channel where a guy brazed in a new accumulator without any flow (no nitrogen)... He said he was 'tired'... Of course, the negative effects come later, so he was able to scam his customer into thinking he had a good technician...

Omg I have ISO’s with my ac unit the blower don’t stop when the ac unit stops so the guy said is my main board that wasn’t working so I need a new one he saids 😢 but I don’t know anything about ac units now I need to know how much is the going to cost me I just paid $500 for this guy to add Freon to my unit and now the blower doesn’t stop when the you unit stops and the main board😢😢😢

[@tc6580]

So many hvac techs preaching the right way to install and service systems yet every tech that i have dealt with over the years cuts corners on installs or misdiagnoses the problem. My last install was done by a company in business over a 100yrs and it was a complete shit show.

[@scotts4125]

I'm in another trade but it drives me nuts when I have guys applying for a job. I ask them about experience and they always scowl and tell me how many years they have been in the trade. I have seen so many guys doing it wrong for years. I always ask those guys how they would handle a situation and there are always more than one way to skin a cat. They skip steps, take short cuts because they are lazy and set in their ways. I point things out and their reaction is nobody does that and it's not necessary. Thankfully they always tell me who they are and I would never hire these clowns.

The more experience you have, the harder it is to be humble

Oh okay, let me have you come out and do a static pressure check on my new house. To find out that the duct work is not correct. what are we going to do completely rip out all of the ceilings and walls in a brand new home to replace a duct work with bigger duct work that won't fit inside of the walls or ceilings.

Sometimes yes. Sometimes no 🙂

[@turboflush]

Hiw long should a unit last? Well out TK units run for a good 20 years until the on road equipment they are mounted to go out of service due to age. Changing parts as needed. These are subject to severe road vibrations, temperature swings, and harsh invironments. But they run for 20 years. Yes the new equipment cools quicker and better. Thats technology. And there are bad versions. Currently fighting compresor burnouts from the newest design; factory sealed. Properly maintained and repaired, HVAC should last a long time.

[@michaeltristan86]

They need to read the instructions before they show up for the install and just refer to it as a review in the field.

[@timcat1004]

I purge the air with Freon.

Well main problem in this industry. Mr. Johnson gets contractor license from the state rent it to Migel. Migel hires illegal Juan and Jose to install the unit. Every home owner should ask installers state issued license and EPA certificate. Avoid Classic American way....

PROPER DUCTWORK IS M-O-R-E IMPORTANT than a fancy high efficiency system. I have worked for companies and had them sell “New duck Work “ on a reference I made to the customer, and they went back with literally the exact same thing🤯. And then insult to injury don’t even set the blower speed correctly ?!!?? 🤯🤯🤯Exactly 2% of service people correctly evaluate ductwork! Make no mistake, it is the absolute most important thing on that system. Time and time again I see companies replace systems and don’t address ductwork! And often times, you don’t have to completely replace it. I find a lot of times a couple tweaks on a few runs can make all the difference in the world. Great video by the way.

Video after video of "professionals" bashing other "professionals". All these videos do is make me even more worried about having work done by anyone. It's such an expensive item and apparently every HVAC guy, except for you of course, is a hack. I'm basically to the point where I'm going to learn as much as I can and do the work myself. Sounds like I've got just as good of a chance at getting it right as all these "professionals".

[@NewHVACGuide]

I don’t think they’re all hacks. I actually think there’s some pretty good ones out there. Unfortunately, there are quite a few bad ones as well.

[@crazysquirrel9425]

I want my vents to blow as hard as a hair dryer! lol Upping your capacity 1/2 ton generally won't give you problems. More than that can easily cause you problems. Remember, as a unit ages, it's CAPACITY goes down. As the climate heats up your AC needs will go up too. Temperature clamp? LOL. Mine are my thumbs and index fingers. Works like a champ! Old timer taught me that one. HVAC system should last a lifetime. Literally. Designed obsolescence just makes companies richer and you poorer. I notices the author did not discuss return air temperature and supply air temperature at the vents. Hmm.... You want no less than 18-22 deg F difference.

This is the second type of videos I’ve seen HVAC TECH’S SUCK & THIS IS WHY I’m all for educating the homeowners and customers but calling your own out on a decent size channel is pretty crappy in my opinion.

[@Anon-oy5gb]

Well I became interested because some of this and more is happening to me right now via a complete failure to do almost anything at all correctly per the frickin instructions let alone checking load or ducting...almost everything was done incorrectly. The only reason we used the HVAC guy was because he was recommended by a lic. electrician who redid our house with all new breaker panel etc., etc. and we were new to ALL of this. I believe the guy took the rebate we should have recieved and when repeatedly asked for an invoice, he'd say, "Oh yeah, I'll have to get that to you." It never happened and he became the flakiest person I've ever known. If I don't get paid from his bond, I'm 100% suing his ass. There's more but, I'll end there. I'm grateful for a video like this and if a follow up about the correct steps to take to go after the person's bond were made, I'd be more than grateful for that too. I'm documenting all and have a new HVAC company that is doing the same on my 1st invoice so far. So screw whomever doesn't like the infomative video.

At the very least I can now observe an installation & point out what is being done improperly, or not done at all. To me the investment was well worth it.
