I was searching for a reliable company to repair my York furnace that stopped working late Saturday night. Checked on Home Stars and High Efficiency had a great review rating from their customers. Called them up Sunday and Sergio returned my call and said Sunday service would be more expensive and would be better to come Monday instead and I agreed. He requested the furnace model # and I text him the information. I spoke to Gilbert from the office and said he would arrange a technician to come and diagnose the furnace. Richard & apprentice arrived with in the designated time between 11:00-12:00 and determine it was the Igniter that gone bad. He did not have the correct part and said the supplier is a bit far and would come back in a couple of hours to install it. In the mean time Richard got the furnace working so we could have heat and let me know to keep it running until they return. Within a couple of hours Gilbert called to update me that the part had arrived and another technician Harry would arrive before 3:00 to replace it Harry came and replaced it and checked it to ensure it was running properly before he left. High Efficiency did an excellent job from start to finish. They kept me updated thru the whole service. Harry also gave me some tips as he checked my humidifier. Great job Gilbert ,Richard & Harry. I will definitely call High Efficiency again for future serve on my HVAC needs. Thank you guys

our neighbour recommended them and I called them because of an error alert we had on the thermostat and they came that day and fixed it. And then I had them come in today for a humidifier and fireplace problem. They fixed one and recommended the solution for the fireplace. the technician clearly knew what he was doing. I'll certainly use them and recommend them to others.

We needed some technical help with re-setting our EcoBee thermostat for the heat pump/furnace activities and left a message with their service manager. We got a text reply very quickly and after giving some details about our issue, they had a technician come by our home about 3 hours later who fixed the problem. We are very pleased with their attention to their customers' needs and can would recommend High Efficiency anytime to our friends and family members.

Harry arrived in a timely manner, was friendly, informative, considerate, knowledgeable, reasonably priced, just a great experience, could not be better. I highly recommend High Efficiency Cooling & Heating.

Had a great experience with them. They serviced my HVAC unit and given that the unit is 12 years old, let me know what problems may arise based on the specific model I have. Very knowledgeable and professional. I look forward to using them again.

I was looking at replacing the 20 year old AC and furnace with heat pump system before needing repair and to take advantage of the Greener Home program. I had a couple of quotes that could be called robbery. Charton from HECH was quick to respond and provided a reasonable quote. Although not the lowest, I decided to go with HECH as a friend had used them and was happy with their service. The installation went okay but had a few problems. The installers arrived late, so the work was rushed and together with injury to an installer took about 12 hrs. The installers were diligent but not the most experienced. Having mixed brand of equipment for heat pump and furnace probably added difficulties to the installation. The problems that I had were: water leaks from broken condensation drain valve in the furnace, the original humidifier wiring were pulled and loosen so stop working, and the equipment stack was not installed centered but each offset sloping to the right thus pushing the return duct and humidifier pushed against the water heater potentially fatiguing the wiring from vibration. Charton and HECH were quick to respond to fix the water leak. So far had no response for installers to return to rectify the equipment placement. I didn't call on the humidifier not working but traced and fixed the humidifier wiring myself.
