I have seen all of your furnace videos and this is the best install so far. I like that you are growing and getting better at sheet metal. I have been a service tech for some time now and would not install my own ac and furnace because I’m too much about aesthetics but I will do installs on the side.

Been 15 years since I last installed my furnace and AC unit. Back then it was difficult to even buy a furnace or ac unit because market was locked up. Now it’s way easier to get. Just bought new setup and was all dropped off in driveway 3 days later. It does take a day to install. A professional with correct tools, I’m sure can do it in a afternoon. But for a days work I save thousands. Best 1 day job that pays well!

I replaced mine about 2 years ago. I've never done it before. It took about 12 hours total time and I saved an absolute crapload of money and did a better job than most professional installers. I did it in early October so there was no conflict with heating or air conditioning. I swapped out an old roof vented 80% efficient piece of junk for a 96.5% efficient Goodman and vented it out the side.

Pretty cool! I’m an HVAC Engineering designer. I spec equipment and duct layouts and make up drawings. It’s nice to see the install, I always try and think of how the installer is going to actually put the stuff together, but that’s hard to do when you haven’t installed the equipment before. This gives me a bit of an insight on how you’d actually go about doing your checks and pull the old equipment out. Thanks for posting! I’m gonna follow your channel. 👍🏼

Where do you work as a engineer designer, that's neat! I've always thought about going that route later on in life. I find it fascinating. I've been in service part of the industry.

@philxcskier Год назад

@@tallboyhec4461 I work in Northern Canada, in a medium sized HVAC consulting firm. I started out in a small (3-5 person) firm. If you want to work in the HVAC Engineering field there's kind of 2 routes, at least in Canada. You can get your full mechanical engineering bachelors degree (4 years of school), then you become an Engineer in Training, and need to work for 4 years and apply to become a full Professional Engineer, with a stamp and legal designation. The other route is you can get an Engineering Technician certificate, its a trades program and I think it's about 2 years. The tech position is more of a support (drafting/site inspection) role since you need a full engineer to stamp and approve your work, but with experience you can also do lots of the design work under supervision. Since you have experience in the service industry that could be a nice fit since you already have some HVAC experience, you would just end up flushing out your knowledge with more in depth theory and math.

@davidwright1752 8 месяцев назад

Scary a engineer that cannot install what they designed. The best engineer is a tradesman that became a engineer. Please do the world a favour go out on job sites and talk to the guys doing the job. Engineers are fairly dangerous people. For example in Australia they designed a train and made some simple mistakes. The driver could not look out the driver-side to see the Marcus to pull up at the railway station. Then they made all the trains 6 inches too high they obviously did not consult. The train drivers never looked into the ergonomics. Never did a mock up to see how the passengers would step on in Brisbane Australia. We talking about hundreds of millions of dollars to create this very basic engineering mistakes, so an engineer theoretical person absolute hazard to every industry. If you don’t go out on the jobsites with mockups if needed and talk to every trade involved you’re just a pencil pusher but doesn’t care. When it comes to try and design, the very brilliant engineers designed a train 6 inches to wide for a train tunnel through a mountain. These issues also happened in the computer industry where programs are designed by people that cannot use them. I do not understand the business or how the end user is to use it.

@petef.4361 7 месяцев назад

@@davidwright1752 I think they also "engineer" furnaces, compressors, etc.. to only last X amount of years before they fail. Great job security for HVAC techs if these expensive components need to be replaced every 5 or 10 years, as opposed to every 25 to 30 years. I know MANY units in my older neighborhood, including my own RUUD system, which lasted for at least 20 to 25 years. Yes they are probably more inefficient, but it proves that they CAN be engineered to last longer, they just choose not to. They just don't build them like they used to. Same goes for appliances. My mother had a refrigerator that lasted for over 30 years, a washing machine for over 10 years, and a dishwasher over 10 years with some minor inexpensive repairs along the way. Now, appliances are "engineered" to last 5 years if you are lucky, and it's cheaper to buy a new one and send the old one to landfill, than have it repaired due to exorbitant costs on replacement parts and labor.

@latehappylife Год назад

My Goodman furnace and ac is 16 years old. Never gave me a problem. Last year I got a few estimates to replace the furnace coil and compressor with the same Goodman units. The estimate ranged from $8000 to $15000 it looks like I have to pay the piper. In my younger days I probably could do the job myself. But at 86 , there is no way! by the way . That is a great video.

This scenario is every HVAC installers dream: upflow in a nice room with plenty of space. However, most installers often have to replace furnaces in a crawl space or tight attics or jammed into a closet in a narrow hallway. I have had to remove water heaters before to gain access to the equipment. The job is really harder than you think!

It really is a straightforward job if the dimensions of components don't change very much. I got a couple quotes to replace 2 furnaces and after a bit of research realized the furnaces were being marked up $3-4000 and they wanted over $4000 for each installation. I bought the exact same furnaces for about $1200 each and installed myself for under $500 and about a day and half of my labor.

I installed my new Goodman 80K gas, 96% furnace a couple of months ago with all new ducts and returns totally myself, I'm very happy with it and after a little adjustments to get a better duct balance I'ts good now. I added an external intake with damper, installed the gas and electric myself. Thankfully I have just heat only so I don't have to mess with A/C coils, condensors and all that krap stuck on top of the furnace etc I had my kitchen where my desk is feel cooler than the rest of the house, and the basement was as well due to insulation on all the ducts. I originally had 2 registers in the kitchen but blocked off one as the room is further from the furnace at the end of the duct run, but I wound up getting rid of the tee that went from thr 6" round to the two registers, and cutting out 4' too and making a straighter shorter run to the one duct and the airflow is MUCH better there now and much warmer. In the basement I cut a hole for a register in the 3x14 duct that goes to one register in the front room where the thermostat is, and partially closed the room's register- it was getting a lot more air and I suspect the furnace was shutting off sooner so the kitchen didn't get warm enough. I keep the thermostat at 73 degrees and the furnace is doing great.

@jdwht2455 Год назад

Great video! One comment I have to make tho you may have covered it - make sure the local government building dept. is OK with a DIY install (permit) and if a final inspection is needed. Now, if you were to do a baseboard hot water furnace, you might do my area a world of good. I did ours about 10 years ago. I even purchased the same brand (Utica Boiler) assuming that the circ pump and zone valves would be a simple disconnect old and reconnect new. Nope. I got lots of copper piping soldering practice as everything was just the opposite. The spec sheets the seller had were outdated. Have to say that the new arrangement was cleaner. I learned a lot plus the higher efficiency furnace helped my gas bill somewhat.

@johnhaller5851 Год назад

The big thing with the building department is that everything is local. This install was apparently in an earthquake area, and flex pipe was required. At my last house, they required hard pipe all the way. This is one of the things where a pro would understand what the inspectors care about. In a different install, all they seemed to inspect is that the AC has the correct sized breaker, since newer AC units frequently are rated for a smaller breaker than older installs. The furnace was not even looked at, perhaps because a local company which always gets permits did the work.

Nice job on that furnace replacement. There is only one thing that I would have done and I did do differently on my gas furnace. Coming up off of the switch box to the box in the ceiling used a piece of three conductor #12 S/O cord with a male plug on the end and then put a 20a receptacle in that box in the ceiling. That way if there’s ever an emergency where the power is out, can have a generator outside run an extension cord inside and plug your furnace into an extension cord to give you your 120V for your blower and controls.

These furnace videos of yours keep getting better and you are giving out some very solid information. However, you did ask for feedback and I'm surprised you didn't take to heart comments about the electrical hookup regarding the Anti-short bushing inside the armored cable and a knockout bushing for the back of the junction box. It was pointed out in previous comments that leaving the wires unprotected can result in rubbing against the sharp edges and slowly, little by little over the next ten or twenty years (or more one hopes!) from the vibration of the motor. When the day comes that the insulation wears through the circuit protection may not trip because you didn't bond the ground to the junction box. And the one on the inside that you didn't fully seat can come loose.

@diyhvacguy Год назад

Thank you for the feedback, I have the bushings on my truck now, so that will be shown in the next install.

What about strain relief? Do you ever do something for stranded wires running from box to box in metal clad? I am not aware of anything in NEC about that. Also there was a comment that an anti short bushing was missed ? Where? I saw an orange bushing supplied in the end of the mc cable.

For solid Wires i would use the Wago 2273 Versions. They have no lever. All you have to do is to push the 11mm stripped wire into the hole and you are done. To loosen the wire, you have to twist it back and forth and pull it at the same time. The Wago 2273's are available for 2, 3, 4, 5 and 8 Wires. (2273-202, 2273-203, 2273-204, 2273-205, 2273-208)

Thanks for your teaching. Can you post the instllation video of replacing the 80% furnace with HE(>90%) that required removing metal duct and installing the PVC for condensation.

@deltasquared7777 Год назад

Really nice video ! - one suggestion: wherever possible use a square drive screwdriver bit instead of a phillips; you have much better control of tightness and it is far less likely to slip out or strip the screws. Phillips screws are designed to cam out without overtightening, but if the screwdriver is or the screw is worn, it does not serve this function properly. (note that you can use a Japanese Industrial Standard -JIS- screwdrivers that is designed not to cam out and works much better than phillips-indeed if you have a Japanese car or bike then using a phillips screwdriver is an invitation to disaster)

I appreciate your making this video. I would additionally have liked to have seen how you cleaned the "A" coil and contain the mess. Some viewers might not have detected that this was a low-efficiency furnace. I would think most modern installations are high-efficiency condensing units.

@diyhvacguy Год назад

It’s all based on how much the homeowner wants to pay. This particular one wanted to spend as little as possible so that’s why they got a lower efficiency furnace.

@paulmoffat9306 Год назад

Would the evaporator work better if you had filled in the gaps between it and the ductwork? Air is likely to take the easy path around the coil making the AC not work as efficiently as possible.

@diyhvacguy Год назад

It’s not a huge gap so it won’t really make a huge difference. I think they’re going to replace the ac this spring so this was a bit of a temporary thing. Why they didn’t opt to go ahead and replace the ac while we were in it is beyond me but that was their call. Thanks for the comment! Cheers

@dattzy2985 Год назад

absolutely will make a difference, the science that goes into evaporator coils and the air that's intended to be pushed through them is delicate, I've seen coils restricted with only a 2" plate, changing airflow and causing all kinds of issues with the system including freezing up. which consequently will cause excess oil to be pushed out of your compressor, causing all kinds of other issues, some being permanent

@PaulHVAC1 Год назад

That is absolutely the wrong answer. By pass air around the evaporator coil is a huge problem.

Pre covid our trucks cost 400 a month, post covid our new trucks cost 1200 a month. Same truck, same setups, equipment costs twice what it did before covid, our starting pay went from 12 dollars an hour to 20/hr. Flex duct if you can get it is twice the price as it was. Copper is more expensive, flux is more expensive, pipe is more expensive, in all honesty I'm surprised equipment doesnt cost more to install.

@shepherdhillfarms7821 Год назад

Cool video! One “issue” I have with what you did; I work in the natural gas industry, shutting of and turning on the gas shut off at the meter is illegal! It is what is considered an “OQ covered task” meaning it should ONLY be done by the gas company. Thanks for what you do! I appreciate how in depth you go and the knowledge you are able to share.

@VideoArchiveGuy 8 месяцев назад

In most areas shutting OFF the gas at the meter is something anyone is allowed to do, but only the gas company is allowed to turn it back on. For example, disaster planning advice is to shut off the gas to your house, and then the gas company will go around turning it back on after your house is checked to make sure it's safe.

@shepherdhillfarms7821 8 месяцев назад

@@VideoArchiveGuy I am in the natural gas industry, turning on/off a gas service valve, the valve before the meter, is considered an “OQ covered task”. OQ stands for Operator Qualifications. This means that to turn off or on the valve, one MUST be on OQ covered employee based on the standards set forth by the federal DOT and the other governing bodies of the transport of natural gas. In the IFGC, gas code book, it states that the only other individual(s) who can turn off the gas service valve are the fire dept in emergency situations, and the “code official” again, in emergency situations but they are NEVER allowed to turn service back on.

@VideoArchiveGuy 8 месяцев назад

@@shepherdhillfarms7821 It warns official personnel will be needed to turn it back on, but even this FEMA document details how to shut it off. www.fema.gov/sites/default/files/2020-08/fema_earthquakes_fema-p-530-earthquake-safety-at-home-march-2020.pdf

@Struthio_Camelus 8 месяцев назад

@@shepherdhillfarms7821 Who enforces the "OQ covered task" requirements? Every time my gas company replaces the meter (7-year intervals) they insist on relighting any pilot lights and performing a safety check on any connected equipment - which is fine. The gas company tech could probably tell that a DIYer was at the meter if there were pipe wrench jaw-marks on the valve, but other than that, who is going to know?

@shepherdhillfarms7821 8 месяцев назад

@@Struthio_Camelus Great question! It really is not enforced. Technically if the gas company wanted to, they could pursue prosecution, but it would most likely not pan out. It is technically against federal law to operate the gas service valve unless you are OQed by the operating company. So, if I am on vacation in another state and operate a service valve, I am in violation of law even though I am OQ qualified with my company in my state. The only reason I commented was to bring awareness. I have been to emergency calls where the gas was turned off, then back on by someone who did not do it right and it caused the regulator to fail and cause a leak. It can be a dangerous situation, and if there was ever to be an incident, then I am sure whomever operated the valve illegally would be prosecuted.

Be sure to read the install manual about this. Many furnaces do NOT allow return from the rear, sides and/or bottom only.

@brandonharvey7939 5 месяцев назад

Instead of stripping the end of the green ground wire and puting a hook on it for your ground screw start your strippers about 2" from the end of the wire and just slide the green insulation 1/2" towards the end of the wire without sliding it all the way off. This gives you something to grab on both sides to curve the wire around the screw without taking the ground screw completely out and dropping it into the abyss. Also works with stranded wire and can be used instead of a ring terminal when in a pinch.

your lucky in Utah to buy this equipment. here in SoCal, only licensed holders can buy them. and as of 2019 can install LoNox. they burn much higher and am told by techs, are more challenging to dial in. Also, the heat exhaust vent needs to be replaced to accommodate the new furnace. on a 2story house, that can add up. SoCal DIY's have been sidelined when wanting to practice what you perfectly preach. Keep up the good show. props to your camera man. BTW what food did you almost smell left in the evaporator. that was gross N funny.

Non marring tools highly recommend. Can't stand tool marks but, as for the Romex wire above the metal duct, I hope it was secured to the joice and not just left laying on top? As for the tape, not a big issue to me, least it is sealed. Oh, one more thing. The flex pipe connector, I use the high flow shut off type. Once installed it will not flow if not connected while gas is in on position. Goes good with the earth quake scenario.

@user-ik7dp1tz9j Год назад

Evaporator coil needs to be flush to sheet metal on the left, right, front, and back to provide proper air flow, this leads to major issues down the line. Mastic should be applied outside of the unit, inside application as shown here leads to it cracking over time and causing issues (not a major issue, just not ideal and you can avoid future issues by applying this outside the unit). Flexible gas lines frequently (at least in my state) require the gas line to be bonded.

the wire leading to the furnace could be sheathed also. It the sheathed electrical wire clipped along the furnace or glued?
