So finishing an energy audit that could not be completed because the AC died. New AC is in but the audit guy made the following comments - overall they did a good job with the exception of:
1. There is 1/2" space between the air handler and supply duct around the bottom.
2. The 90 degree elbows that lead into the vents were not sealed with mastic.
As a consequence the system is not sealed properly and I don't qualify for a $500 rebate until that's done.
System is 2 weeks old. What do you think about these comments? How would you approach install company?
Thanks

I grew up in belchertown ma, and didnt have ac untill a week before i left for bootcamp and dad bought "me" a window shaker. We used to hang sheets in the doorways n open windows at night... And the house never got above 78/58rh i love seeing the big ac boom up there though.
Southern coast of CT gets warm and particularly humid at night. Tonight for example it's only 64F out but the humidity is 95%. We have long stretches in the summer where the temp is 80F+ with high humidity at night - windows or fan I'd probably wake up in a puddle of sweat without an AC on those nights

So today is our first 90F day with 45% himidity and really the first day the AC has been "needed". Still have some improperly sealed ducts so things may get a little better. I set the tstat at 68F just to see if it could cool that low. My new system is a 4 ton which replaced a 3.5 ton and there was some discussion it maybe too big. With the tstat set at 68F the system has run constantly all day and has maintained 70F inside.
On a positive note the kitchen and sun room which have large windows and a southern exposure are much more consistent with the rest of the house. The sun room used to be 8 or 9 degrees warmer on a 90F day and today it's been 73.5F all day with full sun.
It's my understanding a properly sized system will lower inside temp 20F. Is this correct? Is this the type of performance you would expect?
