We had issues with our A/C unit. A technician arrived to our house within the timeframe promised. Our technician, Harry, was very professional, knowledgeable and friendly. He was able to identify the issue and to give us a detailed explanation of the problem and what steps he recommended to repair it. Thank you!

Ali was very helpful and informative. They didn’t push any unnecessary sales and explained all the maintenance and repairs needed, and followed up after the visit.

I was impressed by the meticulous attention to detail the technician (Ali A.) had when servicing my AC system. Ali was professional, dedicated, punctual and efficient. He accurately diagnosed the issue, faulty capacitor. After getting a replacement part, he returned the same day to repair the AC and even worked at end of day to ensure my AC was working. We are in a heatwave and having a working AC was essential, my family appreciated his commitment to great service.

Harry was really fantastic. He was really thorough, cared about my questions, helped look at a problematic vent and worked really hard to fix the issue. He also sat down and explained to me in detail about my HVAC issue - he was patient, knowledgable, capable, and adjusted my HVAC settings beyond his required service task. I've had previous HVAC people just do the minimum and not really care beyond that. Harry was top-notch and I will be a returning customer. Gilbert at the head office was really warm and helpful as well. I would recommend this company without reservation.

Rana was very professional, polite and respectful. He was really helpful in explaining why the blower motor speed was low and walking me through the details of what he did. Rana was very courteous throughout and answered all my questions. I was very impressed by the level of service I received. Thank you Rana.

Technician Rana at High Efficiency Cooling & Heating Inc. did a spectacular job getting the A/C running optimally in advance of the summer weather. He was polite, professional and knowledgeable about the up keep of the unit. The office staff is always wonderful and proactive in scheduling seasonal maintenance at the best times. High Efficiency Cooling & Heating Inc. is my #1 A/C and Heating company.

We could not recommend this great company more. Ali came to help us with furnace that was turned off by a tech from another service provider who came that same morning, claiming that the furnace is dangerously out of order and we should buy new one. He came from a company from which we bought the Carrier furnace 10 years earlier and which was serviced every year with no issues. We thought it an inaccurate suggestion and sought second opinion. Carrier assured us that our factory warranty is a lifelong one, will expire in 2051(!) and gave us names of several associated companies in our area. We called High Efficiency Cooling & Heating and are we happy that we did that! Ali came promptly (the same afternoon), examined the furnace and found disconnected wire, tube and a faulty fuse! After repairing and replacing what had to be done, he then checked everything, found it running well and we had heat! We cannot praise Ali, the company and its staff more. They provided us with honest, prompt, efficient, knowledgeable and conscientious service. We shall always call them for any service. Thank you, High Efficiency Cooling & Heating Inc.

Excellent service and advice! I’ve used High Efficiency for years and they always provide great timely service and advice. Thanks. Lawrence F.

Harry was extremely helpful and efficient in diagnosing a problem I had with my AC, and identified the source of it, which another AC repair guy could not. I'm glad I went with High Efficiency Cooling & Heating Inc. for a second opinion, as Harry was able to help figure out incorrect wiring for my whole AC/Heat/Thermostat setup, which would have caused major issues if not fixed. I highly recommend this company's services.

Late on March 14 out tankless hot water heater stopped working. We called High Efficiency and they came over the next day and assessed the problem, ordered the part that needed to be replaced and on March 16 we had our hot water back, only 30 hours after we first contacted them. We are extremely pleased with their prompt service and professionalism. Harry, the HE serviceman thoroughly explained the problem and the solution! For the past number of years we have always used High Efficiency for our AC, heating and tankless maintenance and repairs. We are very satisfied with their service and highly recommend them.

Positive: Professionalism, Punctuality, Responsiveness Richard was very professional and arrived within the prescribed window. He was able to diagnose the problem and explained to me in detail how the worn down actuator was the reason why hot air stopped coming out of the heat pump. He was able to check if he had the part in his truck and fortunately, he did, thus being able to switch out the broken part with the new one. Richard is very competent and did not mind explaining the nuances of the broken part and answering my questions on the process. He came to the condo fully versed on what had been previously done with my system (I used his company last year to replace the blower and motor) and was aware of the state of my system based on the ”symptoms” I described. Richard reminded me that should anything arise within a week, he will come back free of charge to look at it again. I’m confident in Richard’s work and would ask for him specifically should I need my condo system serviced once again. Service: Heating system repair

Positive: Professionalism, Punctuality, Quality, Responsiveness, Value For over 50 years I have been dealing with various HVAC service companies for my own residences as well as rentals but no service provider has ever come close to High Efficiency including Charton and his installation team. Incredible service even when 12 inches of snow just fell. I now have a new Carrier furnace and exhaust / air intake pipes and humidifier. Two years ago I had the same positive experience when They replaced my central air unit. I shall never use any other service provider for HVAC Service: Heating system installation

We started shopping for a new furnace in Nov 2022. We got quotes from 4 different HVAC dealers , however, we chose High efficiency Cooling and Heating because they were able to answer our innumerable questions. Charlton was our point of contact and he explained in very detail all the technical issues in layman terms for a non technical person. He presented to us a proposal to replace the furnace and also install a new heat pump to replace our aging air conditioner and also explained how we could avail of the Canada Greener Homes grant. He was very professional in his dealings, patient, responded very promptly both before and after our installation with any queries we had. He coordinated with his installation team and the whole process was extremely painless. It took less than 10 hours for the installation. I am so glad we chose High Efficiency Cooling and Heating for our HVAC needs. Having a very knowledgeable technical person like Charlton alleviated all our concerns and worries as he was able to answer and clarify any issues that arose. We highly recommend High Efficiency and particularly Charton for any HVAC needs and upgrades.
