Question about Heating & Cooling
Hi, It sounds to me like you have covered all of the basis. The evaporator coil should be clean if you keep your filter clean and the condensation is showing that it is cooling properly. Normally, when the temperature increases outside, you will loose as much as 35% of your units efficency as it it working very hard. 77 degrees is very good temperature if the outdoor temperature is in the triple digits or a little less. It may be that your thermostat is off just a little also. If you clean your coils and keep it up like he said, that is great! I wish more people would do this. You should have a 18 to 25 degree temperature difference between the supply air from you vents and the return air at your filter. Example, if your supply air is 56 degrees, and the return air is 76 degrees, a 20 degree difference or TD, that is excellent. You can check this with a thermometer. I live in Northern Ca and it gets up to 116 degrees here in Redding!! We are lucky to have it 80 degrees in our home, no kidding!!. If you are unhappy, call this tech about it and see what he says. Your indoor coil is fine if you have no ice and I know you keep your filter clean. If you lost a capacitor again, you would have no cooling. Like I say, keep a eye on it, it could be the stat not accurate. Check the supply at the vents and filter to see what you have. If its lower then 18 degrees or higher then 25, you have a problem. If you are in the triple digits, this will cause this. I wish you the best and keep up the good work on that unit! That' great! Please keep me posted and please be kind when rating me as I know you will. Let me know the out come.
