Replacing a high wall heat pump without surprises

If your old high wall heat pump needs replacing, it is tempting to pick a new one with a similar number on the brochure and put it in the same spot. Sometimes that works well. Sometimes there is a better way to do it.

Did the old unit actually suit the room

Think back to how it performed. Did it keep up on cold mornings? Was part of the room always uncomfortable? Has the space changed since it was installed?

That is useful information. We want the replacement sized for the room as it is now, rather than automatically copying the old unit.

Can the existing pipes and wiring stay

Possibly, but they need checking. Pipe size, condition, refrigerant compatibility and the new unit’s requirements all matter. The electrical supply and isolation also need to suit the replacement.

Reusing suitable services can reduce work. It should be a considered decision, rather than something assumed in every replacement quote.

Check what happens to the old unit

The quote should explain removal and disposal of both units. It should also say whether new pipework, trunking, brackets and electrical changes are included.

A new indoor unit may not cover the same patch of wall. If painting or wall repairs might be needed, it is better to know beforehand.

Compare the finished job

Look at the exact model, useful features and total including GST. If finance is part of the offer, check the term, fees and repayments separately.

Send us a photo of the old indoor and outdoor units, plus the model label if you can. Tell us what worked well and what you would like improved.
