The heat pump technology is the same of air conditioners, be aware, anyway. The performance of heat pumps may fall short of the expected, due to poor installation and maintenance. Though basic heat pump service is a DIY task, heat pumps need to be professionally serviced. Have a competent technician to service your heat pump every 2 or 3 years. That’s important for energy-efficiency, and to prevent problems. Checking the airflow of a heat pump is not as easy as checking that of a furnace, and requires special instruments (HAVC technicians use anemometers or pilot tubes). Air-Flow Problems Heat pumps require a proper air-flow, often estimated at 375 to 425 cfm per ton of heating capacity. They are very sensitive to low-airflow, much more than furnaces. They need to move a much larger volume of air than furnaces, and many installers (used to working with furnaces) do not take it into account and do not size correctly the ducts, leading to structural low-airflow problem...
