Service & Maintenance

An air source heat pump (ASHP) is a system which transfers heat from outside to inside a building, or vice versa. Under the principles of vapour compression refrigeration, an ASHP uses a refrigerant system involving a compressor and a condenser to absorb heat at one place and release it at another.

Just like a car with lots of moving parts and integrated components, your heat pump needs regular tune ups to keep it running efficiently. Artizan recommends annual service to maximize the life span of your investment. Many heat pump manufacturers require that you perform annual maintenance to keep their warranties valid.

If not properly installed or maintained, heat pump compressors, reversing valves, and coils are costly to replace.
