What Our Customers Say

reviews from over 10,000 happy customers, one-third of whom are repeat business or referrals.

I called High-Efficiency Cooling and Heating Inc., to install our Furnace, A.C.& connect gas line to our stove. Initially, sale rep, Charton Teng came to our house and provided us with the thorough detail of the work involved and cost. He was very professional and honest with the way of explaining how the Furnace and A/C properties were, and cost to install the equipment. Keith and his helper did an amazing job with the installation. Amazing job and i highly recommend them to my friends and family!

Rick from High Efficiency Cooling & Heating Inc came to my house last Saturday to talk about the cost of a new furnace and A/C. I wasn’t expecting to decide anything that day. After Rick told me about their Carrier products they were exactly what I wanted and I liked his price. So I decide to go ahead with the installation. The amazing part was they had the new Furnace and A/C installed 3 day later. How is that for speedy installation. nice work.

Excellent customer service! Charton Tang definitely knows his stuff! There was no sales pressure, just straight facts and options/recommendations were provided. The installation team led by Jason was quiet, courteous and efficient! They were totally in sync with each other. The work was great quality, completed in short time and we received a walk through after the installation. We really appreciated the follow up by Charton, just to make sure all went well and that we were satisfied with the installation. I commend Charton, Jason and team for being exceptional in customer service, quality of work, and completing the job early! We’ll absolutely be referring others to them. Thanks for a great job!

Charton was so efficient and professional explaining all my options. The installers came on time as promised, and Charton came by during the installation to make sure all was proceeding well. He answered all my questions and even checked in several weeks later to see if all was well. The price was competitive and the service exceeded all my expectations. I chose High Efficiency based on the positive online reviews and I was not disappointed. I would not hesitate to recommend them.

We found Charton very professional, as he explained the technical facts and options to us in detail together with rebates and warranties available. There was no sales pressure in his approach and the price quoted was reasonable. We also appreciate his follow up visit to ensure that we were satisfied with the installation. Thanks Charton!
