If your air conditioning unit has broken down right when you need it the most (which is usually the case) call Coldflow Heating and Air Conditioning. We’ve been keeping homes and offices at the right temperature around Doreen and Mernda for over 50 years! 

Our family-run business handles air conditioning sales, installation, maintenance, and repair and are the first people to call if you are having issues with:

  • Gas ducted heating
  • Ducted refrigerated heating and cooling 
  • Evaporative cooling
  • Split systems

Need a new system? Coldflow ensure you make the right decision

As we have spent an extensive amount of time in the industry, we’ve seen, worked on and installed a lot of systems. As a result we’ve identified the highest quality brands, and those are the ones we stock. Our range of heating and cooling systems offer the lowest prices and highest-quality units, so you know you are getting the best of the best.

You can view them while getting all of the relevant information at the Coldflow Superstore. You’ll find it at 212 Springvale Road in Springvale if you feel like a visit, or you can contact us for a customised quote and the answers to all of your questions.

Don’t even know which questions to ask? No problems. 

We don’t expect you to be an expert in heating and cooling units. We don’t even expect you to be a novice! That’s our job. We can give you everything you need to know about ducted refrigerated systems, multi-head split systems, gas ducted heating or evaporative cooling. 


"Coldflow were a wealth of information. I didn’t even realise how many options there were or how complex it could be, but they certainly made it all very simple." - Mark G

November 2022
I was very impressed with the professionalism and tecnical knowledge of the sales rep. I was sold exactly the right product with the best price and an extened warranty. I am very pleased as I was interstate when the heater broke and my daughter was the only person at home.
