Different technicians come out each time and they ensure we have sufficient refrigerant for our heat pump system. Also checks the furnace and filters. Recommended ductcleaning which we have not yet taken up. Probably due for one after 23 years. The technician was polite, professional, timely and sets up our system for heating and cooling. Also provided advice on what to look for HVAC companies for our other home. A great company to work with.
