Ali arrived as scheduled and diagnosed the problem quickly. The output line of the A/C condensation pump had been installed poorly with multiple kinks in the line. This caused the water to back up and spread across our finished basement ruining carpet and drywall.

Ali installed the new pump quickly and removed the kinks in the output hose. Although I am disappointed in the original installation, I am very happy with Alis work.

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.

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.

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.

Couldn't be more happy about our experience with High Efficiency Cooling and Heating!

We called them based on reviews we saw and Charton was at our house within 2 days to address what we were looking for. He answered ALL of our questions without hesitation and it became obvious very quickly that he is experienced in his field.

We decided to add a heat pump and tankless water heater, and our experience only got better( sorry Charton haha) once our installer, Lu, arrived.

As promised, the man knows his stuff! He installed the equipment professionally and in a timely manner and answered all of our questions with an educated answer and a smile.

The whole experience is what you would like to expect and deserve, and High Efficiency Cooling and Heating without a doubt is top notch people and products.

Would not hesitate for a minute to use again or recommend to others.

On a side note, it was very nice to find out that during Chartons follow up call and scheduled visit to inspect the installation that ALL paperwork regarding registration and warranty is taken care of by High Efficiency Cooling and Heating.

It was a nice finishing touch to a great experience!

He reminded me of possible leaking risk, demonstrated how to clean the HRV filters and how to protect your AC machine. Even these are not his responsibilities but when you asked, he answered you very detailed. I have to mention Gilbert as well. Thank you so much for your warm and efficient coordination. This is my third time to contact with High Efficiency, every time was an amazing experience.

My furnace didn't work yesterday, still cold in Toronto. Recommonded by my friend, the techonician appeared at my home in 80 minutes after my contacting. That's amazing. He taught me the tricky way to fix the problem temporarily so I could still stay in the warm house.
Today they called me that they had contacted the supplier and could replace the part. I love their service, very professional, it matches their name very well, high efficiency!!! Mr. Yan ,thanks a lot!

Harry and his colleague were courteous and knowledgeable. They took the time to explain step by step all what was done to the machines. Very professional company and great service. Highly recommend them to anyone with heat pump/ AC issues.

The High Efficiency Cooling & Heating team removed our old water heater and installed a new tankless water heater. It was an amazing experience dealing with Charton and team from beginning to end! Charton was very knowledgeable, responsive, and transparent, which made us feel confident moving forward with them. The installation team was great to deal with and very respectful of both our space and time. Charton also did a follow up visit a couple weeks after the installation to make sure everything was done properly. I'd highly recommend!

Good company. Second time I use them for my annual furnace service maintenance. They are transparent, responsive and competitively priced IMO. Harry was the agent on-site and he was knowledgeable, courteous and efficient.
