I dont service A/C, but...
I normally dont service A/C, but a friend called, and said she was having a problem with her cooling. The second floor was doing great, but the first floor just wouldn't get comfortable. I asked her where her thermostats were set, and if they were on "cool" (T-87F, with heat/cool plate). She said she was set on 74, and yes, she was on cool. I went over to take a look. Her 2nd floor thermostat was a heat/cool, controling forced hot water baseboard for the 2nd floor, and A/C for the whole house. Her first floor thermostat controlled the baseboard on the first floor. Both were set at 74*F. The A/C was fighting the baseboard. This will probally explain her next question, about her gas bill being higher than she expected this summer.
She purchased the house from a builder about 10mths ago. I don't think anyone bothered to explain the operation of the heating and cooling systems to her. Just grabed her 300K and walked away.
