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

"Amer did a wonderful job with our electrical and HVAC needs. He was quick and punctual and very professional! Would highly recommend."

"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."

"My husband carefully spelled out his name and our address over the phone, but the office still got both wrong. But besides that, the service tech arrived early after calling us in advance (much appreciated), found that the drain trap was plugged which prevented the unit from moving into the second stage of the heating process, and he cleared it. We're confident that the problem was fixed, and we're pleased with the work he had done. Jim was personable, knowledgeable, and helpful. But for the 20 minutes he was here, and the limited scope of the work that we could see that he had done, we feel that the charge for our drain line flush of $288 was pretty high. We didn't get quotes from other HVAC companies, and we trusted AWE based on Angie's List's reviews, but on reflection, it seems pricey to us. We will nevertheless call them for annual servicing because they are reliable."

"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."

"I talked to Nick who was good enough to send a technician out the very same day that I scheduled the service. The technician, Dan, was very prompt, thorough and friendly. He cleaned and sanitized 10+ vents, HVAC system, returns, supply lines, main line, and the dryer vent which was on the roof. A lot of Groupon deals that I looked around for have up-charges for the requirements that I had, particularly since I live in a 3rd floor walk-up in the city. With Lowe's the price that was quoted was the price that I got! I will definitely use their services again!"

"Rams installed a gas furnace and A/C at two of our properties. They are very professional, they take the time to explain the work being done, complete the work in a timely manner and were very easy to get in touch with during the process. We were so happy with the work done and we recommend Rams to everyone that is in need of HVAC work."
