Please guide me on how to handle my situation.
I just put Central Heating and Air in a rental house. Older home with single pane windows. Originally had window units so it now has all new ductwork.
House is just over 1,000 sq/ft.
AC guy Said the load calculation called for a 2 ton unit. That seemed low to me considering it is a old house with single pane windows and unknown wall insulation. He assured me that it would cool fine.
About 2 days into the install everything was going great. Ductwork was all in. Air handler was in place. Guy said he had a friend coming to help set up the outside condenser that evening and he would be finished.
He asked to be paid because it was friday and he was going to finish that day....... I paid him and boy did things change....
He didn't answer my call for a week and finally 3 weeks later he finished the install... *Still Hasn't ran the exhaust for the heat"
After he finished the install it seemed to be cooling quiet well, but it was raining every day that week and the outside temperature wasn't nearly as high as usual...
A few days after he finished my tenant moved in and has been complaining that the AC never shuts off and will not reach the set temperature even when it's set high. (80). Tenant is worried that the electric bill will be astronomical and has just decided to do without AC.... I don't know how considering it has been 95-100 every day lately. HOT A$$ south MS.
After talking to another AC guy he said the unit is too small by at least 1/2 a ton.
How do I handle this situation. The AC guy is a local independent installer. The equipment is a 2ton Rheem gas furnace unit *13seer* Attic was has brand new blow in insulation covering the rafters.
Thanks for any help or guidance.
