"We were having issues with our current furnace and decided to purchase new equipment versus putting repair money into an obsolete one. Due to the unreliability of the old unit, we wanted the new furnace/AC installed before we went on vacation.  They arrived on time, and completed the work in the time frame promised. All the work was done to the highest quality, and exactly as promised. This work was done on a cold day, and with over a foot of snow around the house, including around the old air conditioner. With the cold temps, we were very happy the total job was done in about 6 hours. The equipment is working extremely well. TR Miller took away all the old equipment, and did a good job of explaining the operation of the new furnace, thermostat, humidifier, and air cleaner. I would highly recommend this company for any heating and cooling work.

"AWE promptly responded to my work request and kept me informed about my appointment status. Peter came to perform the work. He was very thorough and even discovered that the HVAC contractor on our new home installed 2 furnaces: a current year model as well as a prior year model that was more prone to breakdowns. Provided great information and would definitely hire again. Thanks!"

"Very efficient and clean, explained everything clearly, no issues at all. Will continue to use them for HVAC and plumbing needs!"
