"United HVAC installed new furnace and new central Air and most recently new hot water heater. That being said I trust the company and their technicians they do the job right. Communication and outstanding service from everyone. Extremely happy. Thank you United HVAC."

"Jim also replaced an aging furnace. I can't say enough good things about his operation -- prompt to respond, thorough in explaining (down to JPEGs) of problems that need attention, dependable service, good pricing. He recently fixed an HVAC thermostat problem in my condo that had most likely been caused by my tenant's well intended intervention -- with no charge. I would highly recommend him to anyone. Honest, knowledgeable, and a pleasure to work with."

"Professional service, extremely skilled at diagnosis issue. Will continue to do business with Long Shun HVAC"

"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!"

"Jose was on time and started working right away. He cleaned every single vent in the property along with the AC Coils and Dryer vent. Went above and beyond by cleaning the exterior of the air handler, something I don't think was included in the service but I had asked him originally if he knew someone who could do it (the answer was not really, but he did it himself anyway). Didn't notice he had done it until he had already left, but I truly appreciate it! Would definitely hire again!"
