Air Conditioner Maintenance & Heat Pump Maintenance

A.J. LeBlanc Heating's service technicians are licensed HVAC professionals. Our HVAC technicians are proficient in the maintenance of all residential heat pumps and air conditioners. In order to ensure efficient operation, we recommend that homeowners have their central air conditioners, heat pumps or ductless heat pumps cleaned at least once per year. Regular air conditioner cleanings and heat pump cleanings increase operating efficiency and reduce the risk of a more costly air conditioner service call or heat pump service call.
