Absolutely! Any information you can give us will help us more accurately diagnose your problems. First, check the breakers and power cutoffs to all of your equipment. Then verify the settings on your thermostat. Often problems can be as simple as that. Be sure to take note of the obvious problems, symptoms, and noises. Each of these is a good indicator of issues and they help us know where to start looking for problems. The more information we know, the quicker we can restore your service.
