Operation

If your heat pump will not turn on there are a number of ways you can check to see what the problem is. Firstly, check that the remote batteries are fully charged and replace them if you need to. Check for any error codes that may be displayed on the remote control. If safe to do so check that the electrical supplies have not been interrupted, check if the circuit breaker has been tripped and reset the circuit breaker if possible. If your heat pump still doesn’t turn on please contact us.

If your heat pump doesn’t seem to be heating or cooling the room properly, check the filters to see if they need cleaning and check the drain pipe for any obstructions. If this doesn’t help, contact us directly.

If your heat pump is on the cooling setting but is blowing warm air be sure to consult your user manual to check that it is operating in the correct mode. If you continue to have the same issue, please contact us.

Water leaking from your indoor unit can indicate a number of issues. The drain pipe in your heat pump may be blocked; the unit has been installed incorrectly and the water is unable to run off from the unit; or there may be an issue with the refrigeration. If this occurs please contact us.

This is a good sign! If there is water running out of the drain pipe next to the outdoor unit when the unit is turned on, it means that the AC unit is working properly and has been installed correctly.

If there is an odour coming from your indoor unit it usually indicates that there is something inside the unit. Check the unit for any foreign objects and remove them then activate the unit’s self-clean mode to help you remove any built-up bacteria or mould, or contact your installer to come and check it out.

All heat pumps will make some level of noise. Often there is nothing wrong with the unit. If you hear a noise coming from the unit that you haven’t heard before or if there is a loud screeching coming from the unit please contact us.

To ensure your heat pump works best on a hot day, turn it on early in the morning and make sure that all windows and any doors to rooms that do not need heating or cooling are closed. Also, close any blinds, awnings, curtains and shutters in the room to prevent any added outdoor heat and help keep the cool air in.

To ensure that your heat pump works to its best efficiency on a cold day, turn it on early in the morning and open all blinds, awnings, shutters and curtains to bring extra heat into the room. Also, make sure that all windows and any doors to any rooms that do not need heating are closed.

In order to optimise the heat pump's efficiency we recommend that you close all the windows in your house to heat or cool the house at a faster rate.
