What Our Customers Say

Real feedback from Sydney customers about our hot water repairs & replacements.

★★★★★

Jamie from HeaterCare had our hot water back the same day. He diagnosed the issue quickly, explained the options, and the price was exactly as quoted. Professional, tidy and fast—couldn’t ask for more.

Homeowner • Auburn, NSW
★★★★★

We upgraded our old Rheem storage tank to a Rinnai continuous-flow. Selim handled everything— supply, install and compliance—same day. Water is hotter, bills are lower and we gained cupboard space. 10/10.

Apartment Owner • Neutral Bay, NSW
★★★★★

Emergency call-out at 8pm—Selim arrived within the hour, isolated a leaking valve and restored hot water so the kids could shower. Clear pricing and great communication. Highly recommend HeaterCare.
