We recommend having your Furnace serviced in the fall before heating season & your Air Conditioner serviced in the spring before the cooling season. Taking preventative measures helps limit unnecessary repairs and improves your overall air quality!
Frequently cleaning or replacing air filters is one of the best ways improve your system. Other ways include programming a thermostat to stop your HVAC from running on overdrive, keeping curtains drawn or installing shades in rooms that are more exposed to sunlight, and not blocking airflow by closing vents in multiple rooms.
