I figure with as many engineers as we have here, someone should be able to help me with my HVAC question.
Our upstairs system has an issue. When the inside tempreature hits the thermostat level, the A/C unit outside turns on, as it should, and then, 30 seconds or so later, the blower turns on, as it should.
Unfortunately, what often happens if it stays on for more than a few hours is that the blower will stop blowing, but the A/C unit will stay on. If you turn it off, leave it off for just a few minutes, then turn it back on, the blower still will not work. If you leave it off for a while, however (30-60 minutes), it will usually start working again.
Is there any chance that this is a problem with the thermostat, and if I go and get a new thermostat everything will start working correctly? That would be nice, as I know how to do that myself.
The entire system is about 14 years old, so I am a little nervous that it is running up against it's expected life.
