5 Tips on Heating and Cooling MaintenanceNothing keeps your HVAC system in shape like regular maintenance. That means scheduling an inspection in the spring on the air conditioner and the fall on the furnace, If you have a heat pump that heats and cools, maintenance should also be performed in fall and spring.
