Called Sergy today, I had been trying to get my system working all day and he was able to come at the end of the day in extreme heat! Fixed the problem gave me great advice on eventually changing my system as it is over 20 years old. Thank you for your prompt and honest service I highly recommend this company! Will be calling again. Thanks Sergy!

Great service and very satisfied with the outcome. Sergey took the time to explain everything and even provided some preventative maintenance tips. I definitely recommend this service.

This man is one of the best tradies I have encountered. Polite, punctual and most of all is an expert at what he does at a very reasonable price. Last year he serviced my Brivis evap. cooler. He took before and after photos as I wasn't getting on the roof for an inspection haha. This was his idea and I'd never thought about it. He brought all the panels down for a good scrubbing. Other plummers have only hosed them down on the roof. All in all, a very thorough tradesman. This year Serge replaced my four vents in the house. They look terrific, and have a shiny finish for easy cleaning. He cleans up and takes all the rubbish with him I'll happily refer him to my friends with confidence. Thanks again Serge

The following navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.

Serge was excellent. Quick response and lots of communication when I had to change the time agreed. The repair was an old unit and he showed me everything he was doing all the way through - and fixed what I thought was going to be a replacement job!

Sergey was extremely professional and provided service of top quality. He was very thorough and particular with his workmanship, so quality he provided was no question TOP. From quoting to installation of our heater system Sergey has delivered exceptional service quality and we highly recommend him. For any service requirements, installations or repairs call Sergey (AirWaterGas Plumbing) he will have it sorted for you.
