How To Replace your Furnace and AC Yourself | iDIY |

You got this! You can save anywhere from $7,000 to $10,000 replacing your furnace and AC on your own. It's not rocket science. Getting your hands on the equipment can be tricky and you might need someone to come to braze in the AC line, but you can do 90% of this on your own.

Did the exact same thing 30 years ago. Removed old unit, Installed new and had someone charge lines. Wasn't rocket science then and isn't now. Good job.

Tank a.k.a. Compressor - Nice job, great info thanks

I'm in the camp of keeping the old r22 system and maintaining it from time to time with cheap take-off parts the licenced HVAC techs sell on ebay they get for free by removing customers old perfectly fine systems because spending $10 grand is "efficient". Lol.
Video is very well done!

Are you licensed?? no nitrogen wow not good. nitrogen when you were brazing?

I was very excited as a HVACR Engineer to actually watch a DO IT YOURSELF video for the entertainment value. Once you said you involved an HVAC tech I lost interest but great job my man. We need to eventually see a true do it yourself video on a complete install. I would be mind blown if someone actually did the removal and install correctly
Viewers really need to understand how intricate and detailed a proper install is. Introduction of any oxygen / contaminants etc into your system will destroy your system so please do not try this at home. There is very little wiggle room with refrigeration compressors, not to mention air flow, static pressure, using the proper Braze rods and heat protection compounds, sweeping with Nitrogen while brazing, additional refrigerant needs for longer line set based off not only size of line set but length as well, a proper P trap, furnace adjustments, proper vacuum to 500 Microns or less, decay test, potential oil contamination in old copper line set ( R - 22 uses Mineral oil and New 410A uses POE, mixing the two past a very minimal percentage is bad ) making sure you have the proper filter dryer in the proper location, importance of deburring your line set is so much more important than in traditional plumbing, power supply etc . I Can go on for a long time but you get the point. Call the pros as this simply isn’t a do it yourself job

Hmm, notice you have your air filter backwards from the arrow airflow.

Lucky for me, there is an online Goodman dealer who has a warehouse about 20 miles away. I bought all of my equipment right before the pandemic and all of the price increases. I use to work as an HVACR contractor so installation wasn’t a problem. I saved about $5000.
That fresh air vent location makes me nervous if you get any snow, which will block the vent.
In the south, almost nobody installs high efficiency furnaces because it doesn’t get cold enough to justify the added expense.

You didn't use nitrogen when you brazed. You just introduced cupric oxide into the system. It's going to mix with the oil and gum up your txv/fixed orifice. You'll be calling a service tech within a couple of years. Not only that, did you vacuum the system to 500 microns before dropping charge? Also, the flu exhaust hits the dew point, producing water, which then drips back into the furnace. It won't rust it out.... wow. It has a drain for that. That's why you slop the flu towards the furnace. You diy guys really know how to mess up an install.

[richla]

Misleading title, you installed a new system with professional help otherwise you would have needed to hire this out, am I missing something ?

[lilalex]

The hvac contractor left a kink on the suction line outside lol

[Chainsaw]

No warranty! Most, if not all all companies, will provide no warranty unless you’re licensed. That’s a significant issue.

[Xavierpropertyshow]

The only part that confuses me is you drain the old AC into the condenser but where where does the new r40 or whatever it’s called go in it I’ve watched 2 videos that don’t show that part now

[HVACSuperTechWannabe]

Any person servicing, installing or disposing of stationary appliances (except the disposal of small appliances) must be a section 608 certified technician.

Didn’t see nitrogen flowing while brazing, didn’t see vacuum, didn’t see gas pressure checked/adjusted (no they do not come preset from factory), and from my understanding from your responses you are not epa certified and every second of you disconnecting the old system was illegal. Not trying to hate but I am an hvac technician and I would not recommend this at all. At least invest in the proper tools and follow proper guidelines on installing equipment before you “influence” someone to do the same thing and they get killed.

You did a good job for someone not experienced in the trade. Better than I could have first starting out

[AlfredoDiaz-cfsx]

Is that Jake from State Farm? 😂

He said he spent 6K on a good man system. Some buddy maid $$ on that 😂

[glenbeaver]

So it's really not a diy, you've got Jake as in Jake leg? Or as in Jake from state farm? Jake from state farm might come in handy when something goes terribly wrong on a diy.

[haldente-xnse]

In these DIY videos no one is talking about permits or codes or inspections or anything.

[stevebennett]

Good luck on getting your equipment worked on

[michaelcso]

Why did you edit out the part where you released the refrigerant as you cut the suction line.

I guessing you didn’t know that the suction line service port isn’t a one way valve.

What you should have done was during the pump down as the compressor is energized close the suction line

It’s probably better that you didn’t give the EPA the video evidence to fine you the 36k for releasing the refrigerant

[supplyequalsdemand]

This wasn’t DIY. You had an HVAC contractor friend do the technical stuff.

[mattmoore]

You basically ran your system for 2 minutes and then blew refrigerant no different than not even attempting to pump system down. If some follows your idiot advice they will blow a bunch of refrigerant everywhere. I’m a licensed contractor with 19 years follow some one else not him lol
