Furnace and Central AC Question

The furnace and central ac unit in my home is going on 25 years old and probably should be replaced before a failure happens. I wanted to ask anyone in the know if a system could be purchased from eBay and installed by an HVAC person with minimal problems??

My furnace now is a 80% American Standard and the AC unit the same brand and 2 tons.

I'm looking at the eBay deal of a Goodman 96% HE furnace with a 3 ton Goodman AC unit for just over $1800 shipped!

Can a experienced HVAC guy change these out with what I have with minimal effort or is there much more involved?

I think you will have trouble finding a certified tech that would be willing to install customer supplied equipment. And if you do, you likely won't get any warranty on equipment or the installation.

It's rarely just a swap out. New furnaces tend to be a lot smaller than the old ones, while the exterior unit for the A/C will be bigger. There's sheet metal work, plumbing for the condensate drain and perhaps gas, and electrical work. The new furnace will likely be direct vent so there will be air in and exhaust out lines to run. The crews that install them all day have all the equipment and supplies and can do it in their sleep.

C T hit on a very important point..... warranty. If you don't purchase from or have the equipment installed by an authorized company you run the risk of having no factory warranty..... regardless of what the selling companies claim.

For any equipment bought online, Goodman specifically excludes any warranty.

Although I have the requisite skills, when it came time to replace my furnace I opted to have it done. The reasons were I wanted it done in a single day (I would have taken several) and I wanted a warranty. Although after almost ten years I have yet to used the warranty, I still consider it money well spent.
