OK…I have a question or two for all you HVAC folks. This is actually for my house.
I have an ~2200 sqft post and beam, w/SIP walls, and roof. The existing AC units has not worked well for the the 4 years I’ve lived there. I had someone look at it once, and was told it was operating fine. But he also told me some things about the propane fired boiler that were just plain wrong… so now his whole equipment review is suspect. The house gets tons of sun, and has tremendous thermal gain. The unit will just plain not keep up with the heat. Yesterday it was 90, and sunny. The house got to 86, and the ac never shut down. All windows have shades drawn. The AC was installed by a DIYer, and due to the post and beam nature is not the best ducting. Here are a few questions:
Off the top of your head does 3-3.5 tons sound reasonable? I know there are lots of factors ( I did take thermodynamics 1 & 2 in school) but what does your gut tell you?
What is the general opinion of janitrol/goodman.
I think the air handler/coil is rated to 4 tons, while the compressor/condensor is rated to three. Can I upgrade this to a different brand 4 ton unit, and keep the existing air handler? The air handler is in a very close quartered loft in the upstairs, and I don’t look forward to replacing it.
Thanks in advance for the opinions.
Pete
