We're in the socal desert, so it easily gets up to 115 during the summer. We bought the house about a year ago, it was built in 05, and only lived in for a few months....so the air conditioning hasn't had much more than a year of use. House is single story stucco with 1600 sq. ft. It's a goodman air conditioner, as well as goodman furnace/ evaporator in the attic. I can provide pictures and info on both units if needed. It just started happening this past month. We keep our thermostat around 80-82 usually. When it turns on the attic fan and condensor fan both turn on. Sometimes you can hear the buzzing of the A/C compressor kick on, sometimes not, it's about 50/50. Obviously it's not blowing cold air when the compressor doesn't kick on, just recirculating inside air. Both fans kick on every time. When just the fan kicks on, it can take almost an hour before the compressor kicks on, sometimes less, it's just random. What would cause the compressor to only come on half the time? I've heard it could either be a compressor problem, or capacitor problem, is that correct? I've done all the obvious maintanence, like replacing filter monthly, checked all circuits, fuses, just cleaned the condensor coils and straightened all the fins a week ago. No leaks, the bigger pipe does get cold, but not icy/frosty cold like I remembered it being last season. Evaporator in the attic...I can't figure out how to get to that thing, looks really complicated. Anything else I should check that I'm missing? Let me know the steps I should check to get it fixed, it sucks only having air conditioning half the time! Thanks so much for the help!
