I have a call into my HVAC installer to check out my system. I have a 1 zone system w/ the stat downstairs. It keeps my upstairs and downstairs at the same temperature (good), but the most it will stay on during a 95+ degree day is 9-10 minutes and the most it will stay on when its 80 or so is 7-8 minutes (not so good). Given what i have learned on this forum I suspect it is short cycling, and after discussing w/ my installer he agreed it warranted a look.
He's coming out early next week. Anything I should know about the visit? What should he be checking? What should I be asking?
Thanks in advance !
