What can we do about our homes over sized heat pumps?

Question

The heat pumps in our home are oversized. They cycle on and off too often. The house is cold and clammy. We have 6 tons of cooling but by my calculations, we only need 4 tons. Replacing them with smaller units is too costly. Is there a way to derate them or resolve the situation? The compressors have two speeds and the fans have variable speeds. Any advise would be appritiated.

Answer 1

Call in a HVAC professional who knows heat pumps.  There is something wrong if you can't set them to a comfortable level, and it is likely beyond you or me on this board to fix.  It's well worth the hundred bucks or so to get a pro out and have a look.

Good Luck!

Answer 2

If they are over-sized and are two speed then why are they not just running on the first stage?

You cant derate what you have.

Sounds like you need a professional in there to verify your calculations and see if something is not working or wired properly.
