Can I install an HVAC unit myself?


the only advise you pros are giving this guy is how hard it is to install a heating system. You gave this guy no tips, all you did was get defensive because someone was attempting to do something you pros think is extremely complicated.

I've been following Beenthere for years learning from him. I've been messing with HVAC as a hobby and love it. This past weekend I was prepping for a replacement furnace and AC unit. I was going to set the condenser, furnace and evap coil but needed a friend that owns a HVAC company to get a transition made and I prefer him to do the brazing. Suction line is 7/8ths on a 2 ton and I know that's gotta be addressed.

After pumping down the condenser so I could remove the evap I thought -chit I don't have a bottle of nitrogen to break the vac.

Pealing back the armaflex I noticed it was all weather rotted.

After removing the filter grill I noticed the gas pipe came in through the plenum AND had 4 couplings to snake it around the platform framing.

After removing the furnace I noticed the platform was way off level but since the wood was warped I new a rebuild was in order.

Got the power to the disconnect but didn't have the liquid tite fittings for the whip- supply store is 1/2 hr each way.

Just a brief look into a full day that I thought was only going to take a few hours. All I'm saying is that if the OP loves HVAC and is willing to spend many hours studying it, is proficient at electrical, both water and gas plumbing, he's either going to hire a low bid and have both repair and efficiency issues or do it himself and have a probably worse outcome.

If you need heat I understand DIY or low bid but I think it's funny that for 2 units @ $6400 or whatever you will get a static check, rpm on blower adjustment or anything other then a drop and run.

Well, you guys have sufficiently scared me into having the HVAC guy come out. I have my hands full doing too many other projects to learn every intricate detail of how HVAC units work. Hopefully it wont be a drop and run like you said but I dont really care since i'll have a warranty to fix whatever breaks.

He said he'd be here thurs-friday to install the units. Ill let you know how things work out.

Thanks for the advice

The plan was not to scare you off, the question was what did you need to consider before attempting the project yourself. It is up to you to feel comfortable with the project before getting halfway through and then finding out you are in over your head. Sure you could probably figure out how to get it done with a little help from the wealth of knowlege you have to draw upon from sites like this one.

It's always about is it worth it to you in your time, costs, responsibilities, satisfaction, and confidence in what you end up with for a system in your house. But, as you pointed out, that house may not be yours indefinately, and you want to make sure it is done properly for yourself as well as the next guy.

Wow, you're right. Funny how so many people use the terms interchangably..(including, formerly, myself as a minute ago).. A quick stop at wikipedia confirms it.

Self Piercing Screws are also commonly called:Needlepoint Self Tapping Pencil Point
how did you assemble the flue and chimney liner? Nothing it is a sealed combustion unit that vents thru 2 PVC and brings combustion from outside thru another 2PVC

What did u use to measure gas pressure? Manometer http://viot.us/HVAC/product_info.php?products_id=52

What did u use to to connect electrical?
I used a 4 x 4 electrical box with switch on a dedicated breaker

What did u use to connect cold air boot? S-locked together

What did u use to measure chimney draft?
Dont have chimney draft as the furnace has a blower that pushes exhaust thru 2 PVC out the wall.

Also i did not fab the cold air return or the plenum they fab at the sheet metal. bit i did fab a few boots that needed to pass the truss.

Oh but i do have two sheet metal brakes a small one that was hand made and big brake. i did not use either.
