Maintenance and service


Depending on the needed service, certain skilled trades may be required to perform the task. A refrigeration mechanic would be needed to service any part of the refrigeration system while a plumber could repair leaks to water lines. An electrician may be required for any electrical servicing. Fortunately, most mechanical service companies employ all these trades so it wouldn’t be hard to get assistance.

Like most heating and cooling systems, a seasonal check-up is required. The outdoor heat pump needs to be inspected for dirt and debris blocking the fans and coil which can affect the efficiency of the unit. The outdoor unit should also be checked annually for refrigerant levels and pressure. Inside the home, there may be air filters or water filters that need changing. Additional maintenance may be suggested by the installer depending on the system application for your home or building.

An air to water heat pump can last up to 20 years or longer if properly maintained. External factors such as install location and local climate can have a bearing on the heat pumps life span.

We stock almost all replacement parts at our warehouse in Manitoba, Canada. For more information on Hydron-Aire click here


Like any comfort system, the heat loss of the home or building is calculated. Once the heating and cooling requirements are determined, a system can be selected to meet those needs.

Depending on the application and complexity of the system design, the installation process can range from 1 to 3 days. To find a dealer near you click here.
