"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."

"Rob was fantastic. Very knowledgeable. Very kind. He took me step by step through. the whole process of replacement. I appreciated how he made sure I understood everything. In the end a family member helped with a quick fix. For now OK. But for anyone looking for someone to trust and give you honest information. EE'S HVAC is one you should call."

"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."

"Michael was able to expeditiously call me on a Sunday morning with my HVAC issue. He spent more time than I would expect to discuss my specific issues and various options as to how he could help, including same day / Sunday emergency service. He also helped with a couple of troubleshooting suggestions that ended up saving me some costs - we had the system back up and running the same day!! Thank you M!!!"
