Can I install an HVAC unit myself?


Yeah I know, its a bit of an exaggeration. Just trying to signify that DIY is not so appealing as to warrant any fear for losing HVAC jobs. If anything affects that it'll be people not being able to afford their mortgages, let alone their HVAC systems.

Ill probably end up just having the guy come out simply because its more complicated than I thought it'd be. I dont want to fool around with $4,000 worth of equipment.

Thanks again for all the responses, you've helped me weigh the options more accurately.

Really, I installed my own HVAC in a new 2400 sq feet structure including all the duct work. The only thing I had to buy was Aviation snips. Oh by the way it was inspected and passed first time out!

He's posting package units and others are talking about welding linesets, confusing thread. If your replacing package units, there will be NO linesets.
So lets assume the OP is replacing package units, much easier job than a split system.
Can you install it yourself? Yes and like beenthere says, skills and tools.

I taught myself 95% of what I know when it comes to havc and I can do some darn nice work. If you have common sense and take enough interest in something, you can learn it. I started collecting air conditioning sales brochures when I was 8 years old and my grandfather taught me almost everything I needed to know in the electrical field when I was very young.

To the OP. Take lots of measurements and find a sheet metal shop to fab up your metal for you, hopefully you can handle the electrical, gas etc.

I almost quit before I even ran the first duct from the main trunk. I had a hell of a time cutting the first hole, then I figured out I had a bad set of aviation snips, took them back and got a replacement set. I can cut and install a collar in ten minutes.

buy flat sheets and use a cleet to bend corner and zip screw it together and tape to seal. the plenum and the return will need to fab.

Furnace- A brake and sheet metal hand tools for making the duct transitions along with a lock former, can be all hand bent and S-locked together but looks sloppy. A manometer for getting the gas close, a combustion analyzer to get it dialed in right. The manometer and a thermometer for getting the static and blower cfm set up right.
AC-reclaim machine and tank,torches,nitrogen tank and regulator,silphos rod, copper fittings,vacuum pump,micron gauge, manifold set,clamp on thermocouples for checking superheat and subcool,multi-meter for checking amps and voltages and possibly a tank of refrigerant.

That's the basics.

Really?

What did u use for fasteners? how did you assemble the flue and chimney liner?

What did u use to measure gas pressure?

What did u use to to connect electrical?

What did u use to connect cold air boot?

What did u use to measure chimney draft?

Grain of salt

Also The way you describe bending the metal would never pass an inspection.

And the question u asked assumed installation of all different types of hvac equipment, not just furnaces. The cost of all the tools and instruments is ten grand for a well equipped tech.

To say you used only a pair of snips is miss leading because than you turn around and say u used zip screws. Makes a good beer drinking story but does not pan out in knowledgeable company.

Post were removed to keep the thread on track. Bickering is not what this thread or site is about. And any thread that seemed to call someone out in an ill or finger pointing manor was removed.

We give our time freely. No place for back biting. And the pros do not deserve what you are selling.
