Air Source Heat Pumps

According to National Comfort Institute (NCI) studies of properly performing HVAC systems, coil pressure drop shouldn’t exceed 40 percent of the equipment’s rated total external static pressure.

Available in 3- to 8.5-ton capacities, this heat pump’s exact-fit footprint and advanced control technology contribute to easy installation, setup, and maintenance. 

These variable-speed inverter units integrate advanced technology with a rotary compressor, compact electronically commutated motor (ECM) fan, and an integrated inverter control. 

While making the decision to replace a condensing unit instead of repairing it may be a difficult one, some contractors have guidelines in place to help homeowners make such a decision a little less difficult.

Dozens of regulations affecting HVACR equipment manufacturers, along with refrigerant regulations and technological innovations in variable-speed technology, have resulted in a bevy of change for condenser unit manufacturers.

Industry figures are estimates that are derived from the best available figures supplied by a sample of AHRI member companies. 

This single-phase, air-cooled, outdoor unit operates up to 10 indoor units and accommodates extensive piping networks up to 984 feet. 

Just about every manufacturer recommends homeowners have their air-source heat pumps serviced twice a year — once in the spring and once in the fall. Most believe that semi-annual maintenance helps keep equipment operating at peak performance and ensures the unit is ready for the heat of summer or cold of winter.
