How much money can you save if you install your own HVAC system?

Answer 1

You will save money but, You really need to know what your doing.
Good luck and take care

Answer 2

first off, unless you have a license, you cant buy a decent a/c system. no real supply house will sell you a split system over the counter.

in order to play with freon, you need special tools. these tools arent cheap. you wont save enough money to justify the expense of the tools.

as far as duct work goes, unless you have enough room for round trunk line, you cant really save money there either. stay away from duct board...its junk. flex duct should NEVER be used under a house.

a properly laid out duct system will pay for itself by being more effient.

if you are serious about saving money, heres some tips.

1) cut the register holes your self.... have the pro's show you where and how big to cut them.

2) do the framing modifications yourself. the trunk needs room to run.....this means moving studs and headering off cavities.

3) get the plumbing out of the way

4) pour the pad for the condensor. ask the pros exactly where and how big.

5) run the wire. even if you dont tie it in, suppling the wire from the breaker box to the condenser and air handler will save a lot of time for the pros.

6) run the drains. have a primary and secondary drain ran to a point that the pros can tie onto them easily.

7) when they get there to work, stay out of the way. i know this sounds rude, but we know our job. no one likes to have some one in the way.

these things can save you about $500 - $1000

hope this helps,

Answer 3

You will save less than it will cost to have a pro come out and fix it after you screw it up. Do you have the proper tools and equipment to do this ? Do you have a license to work with freon ? Some supply places won't sell you a central HVAC system unless you can show them your license. Seriously, I used to work on HVAC systems for a living....both repairs and installs. It is not for the DIY'er who has no HVAC expirience.

Answer 4

not having a HVAC device, i won't make it easier to be attentive to the information with regards to the technique of the device to warmth or air subject a house.. If the device is super adequate to provider each and all of the rooms, that is logical to end if rooms are close off by technique of final vents the device might have much less section to chill out and subsequently would be under much less rigidity ensuing in using much less potential thereby lowering fee. Too many structures donot have the means for the section which should be heated or cooled.

Answer 5

Do yourself a favor, hire a professional. DIY HVAC and electrical are the most items I see inspecting a house, and the most often done improperly. Significant damage can occur if the system is not properly designed and installed.

Answer 6

I think it depends alot on your skills. Personally I am of the thought a trip to an emergency room for a sheet metal cut a week in intensive care after being electrocuted, a bill from the fire department to put out the fire after installing the wrong unit and a ticket from a building inspector for code violations amongst other things would force me to HIRE A PROFESSIONAL.

Answer 7

If you have the knowledge , you can save 50-66% of professional installation.

Answer 8

it will be impossible to do unless you know how to sweat copper pipes together and add the freon your self.

If you don't then you could save on labor and markup fees on the parts if you set the units your self and run the copper tubs your self and get a pro to do the hook ups and put the freon in.

I think a avg home owner could do the duct work them selvs if need to be done

Answer 9

at least $1,000, and possibly much more. You can buy an 80% efficient GFHA furnace, 120,000 BTU for about $600, and anotehr $100 for a new plenum....and most anyone would charge at least $2,000 to do it...a one day job at most too.

Answer 10

Unless you are talking about a window unit, I do not think a central system is a DIY job.
