Poor humidity control, excessive energy use, potentially poor operation from undersized duct.
I just bought a new house. We were looking at new construction for a while, but I was amazed at what crappy work was being done.
The GC hired the cheapest mechanical contractor available and hacked the units in as fast as possible. I myself found it disgusting.

In addition, most houses, even new ones, suffer from oversized equipment and undersized duct. High humidity can lead to mold and mildew growth inside the home, which leads to poor indoor conditions for the occupants.

I'm past becoming leery, that's why I came here....Which is why I am now trying desperately to figure out the Load calculator, so I can have something to take to the builder as proof because right now I'm just a guy who read into something on the internet from so call professionals and not a professional like he is (That's what the HVAC guy response to builder after he mentioned my concerns again to him. He obviously or at least I would hope didn't know the builder has him on speaker phone.) My builder told me he would be glad to look at a load calculator after he hung-up I presented him one.

I Agree with What rider said above. The comment your contractor said is bogus, it'd make me leery of letting him do the work.

My friend just bought a house that was built by a spec home builder and has into the same thing...He is in 2 year and the ductwork had to be replaced due to being undersized and now the coils in the outside? unit needs to be replaced...When he spoke to his HVAC installed the guy told him the part was under warranty but the labor is $. He said questioned how new the HVAC still is and the HVAC said he had a number to meet and that's what he did....It 's a basic unit. That's why I am wonder how dependable mine will be because he's not the only one I know with spec home builder HVAC horror stories.

Georgia.....very hot and humid.
Very important to size properly. He says it's more efficent to oversize for less runtime. But how can you dehumidify with the unit cycled off?

Must be that increased efficiency from over sizing that causes people to have higher electric bills. I'll take a smaller less efficient one and have lower bills.

Thats what the whole house dehumidifier will be for. Since the A/C won't dehumidify nearly enough because its short cycling.

I spoke to the builder but he could not find a model number for TXA6. Can you provide more information please...
BaldLoonie said:
That A/C is essentially a Carrier 24ABC6.

The TXA6 is the deluxe version, more features, compressor protection, sound deadening, 5 year replacement warranty if the compressor dies. Then mate it with a FVM4X variable speed air handler, you'll have a nice system.
