Sam from High Efficiency cooling and heating came today to service my furnace. He was very professional and on time and gave me a very detailed report on what he did today and provided me with recommendations. Thanks Sam for your visit today.

My furnace system sent me an email indicating there is a blower motor fault. Harry Yan (technician) of High Efficiency Coolong & Heating Inc. came on March 18, 2025 and he diagnosed that it only occured once. However, he noticed the inductor was extremely noisy and he recommended it to be replaced since it is still under warranty, I just have to pay for the repair labour cost. Harry Yan will return when the part is available.

I have used this company's services for many years and have always been completely satisfied with the service provided. The servicemen have always been courteous and friendly beyond expectation. The gentleman who came yesterday was not only polite and knowledgeable he actually set ip my thermostat to get me the temperatures correctly programmed which I had been trying to do dince the fall! He made sure to wear his booties to ensure my floors would remain clean. He checked all aspects of my system, cleaned the humidifier and replaced my filters. He was welcoming when I asked questions yet totally unintrusive when I set about other tasks. Delighted with his attention to detail and his overall service. Thank you for another year of great service! See you next year!

Marco the Service Coordinator from High Efficiency Heating & Cooling has been amazing to work with. The heat pump chassis that I had purchased less than 2 years ago was leaking and so my condo wasn’t heating to temperature set. Marco dealt with the distributor and managed to get me a replacement chassis installed within days. He’s very responsive and always manages to squeezes me in at the earliest available slot whenever I’m in need of an annual cleaning or for any diagnostic. Thank you Marco & team for the amazing work!
