Without getting too philosophical or going too far into the nuts and bolts of system sizing, etc., hypothetically, when the right system is in the right home, what is the degree of cooling a homeowner should expect in the current heat wave on the East Coast?
Last spring we had installed a new Trane system - I think the XL14i, 2.5 tons. It does great until these heat waves. It will maintain 74 degrees normally, but in the heat wave, by mid-afternoons, the temps rise on the first floor to 78 and a little higher on the 2nd floor. Overnight, the system "catches up," but it isn't until 7 a.m. that it hits back down to 74 degrees. Now that we are in the 4th day of this thing, last night the temp on the first floor of the house went to 79 and this morning it was only down to 76.
I don't want to bombard a professional for a service call right now if it's not warranted. When temps are 95+ and heat indexes are higher, is 78 degrees what I really should settle for? Or does our new system maybe need some tweaking?
Thanks for any thoughts on the issue.
