Performance Testing
Not sure if your system is working like it should? Maybe it’s cooling unevenly, running longer than usual, or your power bills are creeping up.
We carry out performance testing on residential AC systems under 18kW to assess:
Our technicians will give you clear results and honest recommendations — whether your system just needs a tweak or it’s time to consider an upgrade.
Hydro Cleaning
Even the best AC system gets clogged over time — with dust, mould, pet hair, and other airborne particles. A standard service can’t always reach deep inside the unit. That’s where hydro cleaning comes in.
