I have an electric two part a/c unit, part outside and part in attic in Scottsdale, AZ. 110 outside.
Unit only runs during cheap electric rate time .....7pm til head off to work at 9am then we shut the unit off.
Changed to an easy flow airfilter as the tech advised and still....
The unit was blowing HOT air so tech came and recharged the freon.
The unit blows some cold air but when we Set the unit at 70 it only cools to 79.
a/c unit goes on and off but never cools the house down enough.
Tech checked freon again and is at proper level and says nothing is wrong!!!
Never cool below 79 means something not working to me!!!
How can that be??? Could it be the part in the attic or the thermostat?
Proper freon level and blows some cold air sometimes but does not cool below 79 when set to cool at 70 and hold.
What should I ask the next tech to do? What can it be? HELP!
