Don’t forget to turn your clocks back. Fire departments recommend that you change the batteries in your smoke detectors. And #CICPittsburghLLC recommends that you tune-up your furnace. Did you know that the ratio regulators that control the air/fuel ratio on your furnace burners are affected by the seasonal variations in air temperature and pressure? To ensure that you are getting the most out of your combustion system, it is important to regularly check and tune the combustion settings. Call #CICPittsburghLLC to schedule your service visit.
