Your furnace may not be on your mind yet with our temps in the 70-80’s right now, but it will be time to turn that thermostat switch before you know it. (Note) All that dust your furnace has collected will burn off at first start up. Have you set an appointment for your furnace check and service appointment yet? Call R&K Air Conditioning and Heating to schedule an early appointment. You don't want to put it off and get caught in the cold!
