"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!"

"This was my first experience with Sanchez HVAC services and I was very pleased. They were responsive, friendly, and professional. The work to be done was explained in detail and there was no attempt to upcharge for any services or parts. I'm very satisfied and I highly recommend them."

"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!"
