Hello - I was wondering if you could give me some advice. I have a 7 year old Lennox compressor (HP-24 18 or something similar) hooked up to our Lennox heat pump. When I turned on the AC this summer, I noticed that after a day or two, the compressor would shut off, but the blower/fan would keep going, and the compressor would not come back on. Since the temperature starts going up when this happens, the blower never shuts off. If I turn the system off at the thermostat and let it sit for a few hours, it will come on and run fine for a a day or so, but it eventually falls back into this same pattern. It seems like the time it takes to fail is getting shorter and shorter. We have a thermostat provided by our utility company that is all digital, and allows the electric company to cycle our system off during peak demand periods. Would you recommend that I start with the thermostat, or just call an HVAC guy to check it out? Anything I can do on my own to test or fix? I read that sometimes when the unit is low on freon this can happen.
Thanks for any help you can provide.
