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.

After 18 months the cooling stop working. A month ago I had the same problem but it was resolved by restarting the unit. This time it wasn’t resolved. I called service on a holiday and got a reply quickly and an appointment for the next day. The technician Sam came on time and methodically traced the problem to the 4-6 wire converter. Quick and reliable service!

We had installed a Carrier heatpump 2 years ago, and have been having problems with this unit from the first week of install. Sahil was very thorough in helping us resolve the heatpump issue, which seems to be working well so far. I wouldn't recommend a heatpump to anyone; however, I would recommend Sahil, who gave us very good customer service.

Liam explained well. From him, I learned that the transformer needed to be replaced. Still waiting for the replacement on day 2 though.

Technician Rana did excellent work in replacing the humidifier filter and the furnace filter, in checking the heat pump, in inspecting the furnace and finding a leak in the collector box and in answering my questions about the smart thermostat. Rana performed excellent work and my wife and I are most pleased with the excellent original installation of a furnace, heat pump and water heater performed by High Efficiency & Cooling and their excellent follow-up customer service!
