"The technician did a very good job cleaning the hvac ducts."

"Highly recommend. Found this company last year on Angie's List and this is the second time using them. I was in a pinch as the A/C went out and we have a little baby. I called and they got someone out the same day. Jeff was great...knowledgeable, friendly and answered a lot of questions! Got the unit working again! These are my go-to HVAC guys!"

"This is our second year in our home and we realized last winter that our backroom addition had little-to-no heat flow and was frigid cold. Our goal was to make that room usable year-round. We bid with two other HVAC contractors and we pulled the trigger with Jim and his team. What put them apart was that they took their time assessing our home and situation, walked through all possible options, and clearly communicated those options. They evaluated and wanted to find the most feasible option for us, with efficiency and cost in mind. The other contractors came through and kind of already had their minds set on what heating system to use. Jim is also very personable, knowledgeable, and easy to communicate with. Jim and Carlton's proposal was the most cost effective overall - the unit/system itself and our personal ROI. It was gas as opposed to electric, the job was the least complex in terms of labor and construction, and it's functionality was worth the price."

"Everyone from the sales person to installers were great. I love our new HVAC system!"

"Francisco of United Heating and Air Conditioning is the greatest, and I will hire him again happily and hope to have him service my system yearly going forward. He came today as promised and found that my thermostat only needed batteries, but my system was otherwise fine. He is very good and extremely honest and informative."

"He is very patient in fixing my furnace. There were multiple fix he did and now my furnace is working as I wanted it. Other HVAC contractors were unable to fix, but he was able to get the job done."

"I needed the refrigerant in my HVAC system refilled and Juliano and Richard were quick to respond and very professional. They inspected the system and completed the job in one day. Very satisfied with work performed."

"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!"
