Repair older R22 system vs replace with new R410A unit? Need answers fast!


So you agree 74 isn't an acceptable temp? I know I've lived in lots of apts where they dont want to fix the air and they'll tell you temps even higher than 74 means the air is "working fine, nothing we can do it's just hot outside" etc.

i guess i should buy a thermometer and measure the air temp at the vents. feels pretty cool by hand, but nothing stunning.

Just a little worried this is the best it can do brand new.

Oh and its a heat pump too of course if that means anything RE:tonnage.

My A/c will do a lot better then just 20 degrees cooler then outside temp. If I sped my blower back up to 400 CFM per ton, I could do 66 when its 100 outside.

Its a new unit, it should have a 1 year labor warranty, call the guy back out. And let him know you expected the size increase to mean it would cool beter then the 2.5 ton did, but its not.

Yeah probably going to do that in the next few days. Guessing he's going to give me a lot of "dont know what to tell you, everything's working fine, everything checks out" though. (Again, dealt with a lot of apartments that dont want to fix the air)

And yeah, have the 1yr labor etc.

This isn't an apartment you rent. its your house that you paid for a new unit. And he told you it was bigger, so it would cool better. right.

Texas heat isn't any different than anywhere else, just months of it on end instead of days. My 2 ton cooled to 74 with no problems when it was 108 out. Anyway...Goodman has extended performance data so have the guy check actual BTU output vs what it's supposed to be. It should match within 5% of what the chart says.

Yesterday system was keeping it 72 with 102 outside. I'm pretty happy with that though my brother still thinks I should call the guy.

not sure why the difference from the 98/74 day. Humidity somehow a factor? Started from a cooler inside the house temp in the morning (aka air was turned down lower in the early morning? I am not sure if that was true)? System breaking in?

Seems like an awesome level of performance yielded by your new system.

One suggestion I would make is to check on the return and supply plenums. It is my experience that they become separated from the furnace some time after the installation, and cause the furnace to take in and push out the air into the attic.
