First off..Thanks to all who have replied to my previous postings. As a home owner who has no concept of all that is involved in Heating/Air, I find this site very educational!
From my readings here, I have learned the importance of the Manual J for sizing. Lucky for me the company that put in my new Furnace/AC 2 weeks ago did too. My question has to do with how much my AC should run at design temp. Am I correct in my understanding of some of the posts Ive read here that if it is 95 degrees outside, and the system was sized to do 75 degrees cooling, that the unit will run constantly to maintain the 75 deg inside temp? Today was a good test with outside temp at 98. House kept to 75 degrees and ran for about 20 min every hour from 4pm till now. Just kinda wondering if this may mean something was off on the J, or if all of the extra cellulose and new windows are working like they should.
Thanks for any input!
