What to expect

What customers say

Rated 5 out of 5.

Our hot water died on a Sunday night. Matt was here by 8am Monday with a new unit and had it running before I left for work. Price was exactly what he quoted.

Swapped our old electric tank for a heat pump and walked us through the rebate paperwork. We're already seeing it on the power bill.

Questions about hot water systems

Repair or replace?

If your unit is under 8 years old and the tank isn't leaking, a repair usually makes sense. We'll tell you straight if it doesn't.

Can you install a heat pump?

Yes. We install the main brands and lodge the rebate paperwork, which can take a good chunk off the price.

My tank is leaking from the bottom. What do I do?

Turn off the cold water valve at the top of the tank and switch off the power or gas, then call us. A leaking tank can't be repaired.
