These guys are excellent, they know exactly what they are doing, cleaned up everything, there advice is excellent, workers are very friendly. If you're looking for a friendly, local quote or the very best workmanship I've seen, I could not recommend Jason high enough. Thanks guys.

Approximate cost: $2400

We had Efficient Air install our evaporative air and I found their service to be brilliant. Jason spent ages at our house quoting both cooling and heating and then when the installers came out they could have been more efficient and friendly, and the follow up has been fantastic. I would highly recommend them to anyone in the area who needs heating or cooling in their home.

We've used Efficient Air for both heating and cooling. Both systems are great, now we're warm in winter and cool in summer. Thank you!

Was given Jason's name after our ducted heating system broke down (30yr old unit). Efficient Air, gave us a quote which turned out the best of 3, and were very detailed in their appraisal of the job. They changed the heating system over, did some extra ducts inc some hard to reach positions, and also installed a "smart" Nest Thermometer which we'd purchased before but had found it hard to find anyone to install. The Thermometer gave some problems syncing initially and they came out twice more without charge to get it setup and working well. Very impressed with the work and attention to detail. Also if anyone has been finding it hard to find someone to install a Nest Thermometer give these guys a shout.

Our house was freezing last year so I figured it was time to do something about it. After choosing to go local, I discovered Efficient Air. Jason came out and discussed the pros and cons of a few different options for our house (which is 3 storeys and hard to heat!), and provided a detailed quote on the spot. In the end we went with a ducted system, and oh my god, the difference!!! The entire house literally warms up in 5 minutes. Jason provided great advice, the unit was installed within 2 weeks of quoting and it only took one day to complete the installation. Great price and speedy service - would definitely recommend to those in the Hills!

Jason and his team were honest, professional, friendly and customer driven to deliver. No question was to silly and he and his team made us feel confident we were dealing with trustworthy people. With his expertise and no-nonsense approach, he was able to overcome a particularly challenging installation to my premises. His price was fair and reasonable. He even came in under his own initial quote which is a nice change from companies that usually overcharge and pocket the difference.

Approximate cost: $6000

I had a problem with my ducted heating and called Jason to find out whether he was able to have a look. He called me back straight away to explain that he mostly installs heating equipment rather than servicing it, but he gave me a recommendation for a local company (Simkat Gas Service) who were able to help. Jason also gave me information about costs of new systems in the event that mine couldn't be repaired. I appreciate that he took the time to call back and gave me a reliable referral.

(I had to give ratings for quality and value - I'm not able to assess these directly).

Replacement of external gas heater and all duct pipes. Jason's quote was very competitive. He inspection of the old unit and pipes was very thorough compared to some of the other companies' reps. who visited and gave quotes. The work was undertaken on the date scheduled and completed within 7 hours of arrival of his two employees, who also removed the old unit and pipes and all rubbish. I am very happy with the new system. I heartily recommend Jason's company- I have no connection other than as an extremely satisfied customer.

Approximate cost: $3,800.00

Replacement of ducted heating system, and an air conditioning system added on. From the first initial visit we were given,all alternatives, our questions answered and our quote was very competitive. The work was completed within two days by efficient,polite staff, the worksite was left clean and all rubbish removed. The new system is quiet,running well on both heating and cooling options.

Arrived home late on a 37 degree day and the cooling wasn't working, I rang Efficient Air after hours (they installed our ducted heating a couple of years ago) and was expecting a couple of days before a serviceman could come out. Well to my dismay, Jason assured me he would have someone there at 8:00am the next morning, true to his word 2 of his team arrived at 8:00am fixed the problem and I was back up and running, that quickly. I would like to say thank you for a very professional and affordable service and would highly recommend Efficient Air for installations and service work. A business that prides itself on customer service, thanks Glenn
