Hey, I have an all goodman system, Gmnt100-4 furnace, u-49 coil, and a
clt48-1a compressor. This replace a heil heat only system. Heat works
great but the a/c doesn't. I't will not cool down the house. 2 techs
said the charge was good. 1 tech didn't know what was wrong, the other
says the u49 coil is too small for the clt48 (13seer) compressor. He
said even though there both 4 ton, the u49 was made for a 10seer
compressor. He want to replace the coil w/ a 5 ton. Are they not
compadible? Is this the right thing to do? I was wondering if the duct
work in the house was too small and I'd be better off with a 3.5 ton
compressor w/ the 4ton coil. Any Ideas? Running the a/c w/ the cover
off the furnace doesn't help, I guess that means it has enough returned

air. It doesn't freeze up. Thanks

The A/C may be undersized. When the sales guy did the Manual J
calculation, what did it say you needed in BTU? Is your duct work sized
appropriately for the airflow required at 400 cfm/ton?

If your response is "the contractor didn't do a heat gain calculation"
then you know what to do next, right?

Nothing wrong with that combination....44K BTU output.

I would have matched a u-61 with that condenser for a higher seer
rating. The 49 might be just enough with the variable speed
blower but I would still go with the bigger coil with a 4 ton
condenser.

Sucks pretty much when you keep looking for the cheapest drunk you can
find to repair your system, doesnt it?
You get what you pay for.

That certainly seems true about your response.
