What heat pump is right for me? 

There are some key considerations when choosing the correct heat pump for your area.

• The size of the area

• The number of windows in the area

• The local climate

• Current insulation in the area

• Possible location options

Choosing the right heat pump is critical in ensuring your space can be adequately heated while saving as much energy as possible, A heat pump that is too small will be ineffective in bringing a room up to the desired temperature while a heat pump that is oversized will turn on and off frequently, wasting energy and causing wear and tear

How long does it take to install a heat pump?

A typical back to back installation of a single split system, takes approximately four hours. Meanwhile, installation on an internal wall can take up to one day. Times may vary from project to project, depending on the complexities of the building, pipe runs or electrical requirements.

How often do I need to service my heat pump or air conditioner?

As a guideline, it is recommended that commercial systems have a thorough annual preventative maintenance check, coupled with three quarterly filter checks. Residential units require a comprehensive service every two years as a minimum (when filters are being cleaned regularly).

How long will my heat pump last? 

Good quality equipment, installed by qualified contractors, can have a life span of 10 to 15 years. Poor maintenance and environmental factors can cause premature failure. Regular inspection and maintenance will allow your system to operate normally for as long as possible. 

Do heat pump filters need to be replaced?

Heat pump filters do not need to be replaced unless they are damaged. To best prevent damage, heat pump filters should be cleaned regularly.

How often should I clean my heat pump filter?

A commercial unit requires a quarterly check, as part of an annual preventative maintenance plan. For residential units we recommend you review your filters and clean them monthly, as they become dirty quickly.
How much do heat pumps cost to run?

The EECA (Energy Efficiency Conservation Authority) has identified heat pumps as one of the most energy efficient forms of heating around. Heat pumps do not create heat, they simply move available heat from one place to another. The little energy that is needed is predominantly used to run the compressor. A heat pump typically uses 1kW to create 4kW of heat.

Are heat pumps noisy?

No. The leading brands on the market have very reasonable noise levels. You will find most of the noise you are hearing inside your house is the sound of the air being forced out of the internal grills, similar to a circulation fan. You can control how fast the internal fan runs and thus its’ noise levels, by using the remote control.

Why does my heat pump make noises? 

A heat pump can make a sound like air being exhaled or gurgling when defrosting. When the temperature drops, heat pumps need to perform a ‘defrost cycle’ to remove ice build-up on the outdoor coils and maintain efficiency. This can mean your heat pump will temporarily stop operating or will blow out cooler air. It is important not to turn your unit off whilst the defrost cycle is running.
