Best Heating & Air Conditioning / HVAC In Oshawa

“David is an absolute gem of a guy, extremely talented in his trade. His company was hired by my contractor to prepare the HVAC for a renovation which had David working on a number of items. A consummate professional, he made a number of common sense recommendations that I appreciated, not once attempting to "upsell" services that I didn't require. His workmanship was excellent, he kept the jobsite clean, and his costs were reasonable. What more can you ask for? I highly recommend David, and will be calling on Cassar Heating & Air Conditioning again in the future.“

“We have called Elmridge for all of our HVAC issues over the years, using for furnace conversions, replacement installations and A/C repairs. Justin is knowledgeable, professional and reliable. He always explains what exactly needs to be done. A great response time and has come through during a heat wave and an emergency repair over the holidays. Competitive and affordable rates.“

“Have been dealing with Cullen Heating and Air Conditioning Inc. Oshawa office since they installed our furnace and A/C unit 10 years ago. We get them serviced yearly, and from Maureen, the helpful voice who always answers the phone to John, the service technician we have dealt with the last few years, we couldn't be happier with their professionalism, and helpfullness. We had an A/C problem this morning (the hottest day this year). One phone call to Maureen at 8am, and John was there by 9 am, and solved the problem. We recommend Cullen to anyone looking for a helpful and reputable dealer.“
