If your heating or cooling system isn’t working, the first step is to check your thermostat. Make sure that you system is turned on, set to the proper setting (‘Heat’ or ‘Cool’), and that your desired temperature is above or below the current temperature. The next step is to check that your furnace is switched on and that you haven’t blown a fuse. If you are still having a problem, contact the experts at Rich’s Plumbing, Heating, & Air Conditioning for an in-home consultation and inspection.
