Harry was great! He even pointed out an issue that I need to look out for before my furnace is out of warranty. Thanks, Harry!

My old high efficiency Lennox furnace was reaching its end so I obtained quotes from several local contractors on a new one. After comparing their service proposals and features of major brands Carrier, Trane and Lennox, I hired High Efficiency Cooling & Heating to supply and install a Carrier Performance furnace in mid December, 2019. From the onset I was very impressed by the knowledge and attentiveness of our sales rep Charton. He took time to study our existing system and duct work and explain which model would best fit our need and, he was the only rep who went through in great details about the what and how of available Enbridge home improvement rebates. The price quoted was not the cheapest but very reasonable considering the quality of installation, the extra details of the work, the extent of Chartons going out of his way to accommodate us and facilitate the energy audit, as well as the labour and parts warranty offered. The installation was excellently done by 2 master technicians, led by Lu. When they unboxed the new furnace they advised us right away that there was a dent on the side and they needed to get a new one from warehouse. Although it took an extra 2 hours, as customer we appreciated such a responsible practice. The furnace made a significant difference in heating comfort of our house. I highly recommend this company, and get Charton to quote if you can.

Excellent Service Sam was great! I received a text that a service tech would be arriving today per scheduled furnace maintenance. He arrived between the stated time and was very respectful of ones property. He was prompt and diligent at ensuring all parts of the furnace that needed to be maintained & adjusted. He fixed gas limiter spring to adjust gas flow. He was great going over what I needed to know and if I needed to monitor anything in particular. He left, job done, very clean. Great job, Sam! And have been with High Efficiency for almost 15 +years for both heating & air conditioning. Very satisfied and highly recommended.

Thank you High Efficiency (HE) technician coming in today to perform all furnace-related checkup and maintenance. I am confident with HE and am at ease all the way because I know in advance what the tasks will be (a list of the jobs has been forwarded to me days ahead) and the technician kept me informed of what he did as his job rolled out and completed.

Liam was thorough with our annual furnace maintenance check and answered all of our questions. He laid out our options and made really helpful suggestions about how we could proceed with our aging furnace and also what to do with our A/C for an upcoming reno. We really appreciated his input. Weve used High Efficiency twice now and have been really pleased with the service.
