Servicing and Maintenance of Air-to-Air Heat Pump System

Air-to-air heat pumps require relatively low maintenance. However, it is recommended to have an authorised installer to check the condition of the system once a year. For improved performance of the heat pump, it is also recommended to replace the air filters on a regular basis.

Sometimes, if the temperature outside goes below zero, ice may form on the outer block of the heat pump. Under normal circumstances, it should defrost automatically. However, you might want to defrost it manually to make sure that the device is intact and operates smoothly. It is essential to remember to switch off the heat pump before you start the defrosting process.

Features of an Air-to-Air Heat Pump

Low Temperatures

This type of heat pump system is designed to operate below the freezing temperature. Most of them can function when the temperature drops down to – 15 degrees Celsius. However, if you live in an area where the humidity is high with the temperature being below zero, a ground source heat pump might be a better option for your household.

Air source heat pumps absorb the air from the outside which goes to the compressor of the device, and that makes them weather-sensitive. On the other hand, a ground-source heat pump produces heat from the solar energy stored in the ground.

Noise Level

The level of noise produced by the air-to-air heat pumps is considered to be moderate. The noise level of modern heat pumps is quite low though. However, it will depend on the size and age of the heat pump. Thus, the bigger and older the heat pump is, the noisier it can become. Considering this, it is recommended to install the inner block of a heat pump further from the bedroom area as well as the outer block further from your neighbours’ patio.
