"We had a new heater installed by this company. The process was so easy. Everything was explained with detail from start to finish. We also used them for routine services. They always respond promptly and come out quickly. We will definitely use them again and recommend them to anyone looking for HVAC services."

"Highly professional and the work was done immediately the next day. I was quoted a few prices but his estimate was a lot less. After everything was finished the estimate was the final cost (no extra fees)of the new AC unit with installation. I highly recommend Sergi and Breeze Construction."

"Air conditioner inspected and repaired."

"When I contracted with Dave, he gave me estimates that included what it would cost if no posts needed replacement or if posts did need replacement. Upon inspection, Dave said that no posts needed to be replaced. He did repairs on 3 posts & replaced the bottom trim on all 4 posts. He then repainted all the posts & fascia. I was so happy with his honesty,work & reliability (he kept all appointments, reminded me when he was coming & arrived on time) that I am contracting with him to do some other jobs around the house."

"Our central air stopped working mid-Summer 2018, at the time, strapped for money and in need of a simple fix, Nelson stopped over and offered a ($300) stopgap solution to our 18 year old HVAC system. At the time he examined the system in its entirety and let us know that if was only a matter of time and to start thinking about making the investment toward a system replacement. FFWD to today, we hired Nelson and his team in Spring 2019 to replace our entire central air system. Nelson provided several options, as well an in-depth description of each. Ultimately we decided, while fairly expensive, to go with a higher rated system that would provide our family with a reliable system for many years. Nelson clearly understands the financial commitment that homeowners are making when confronted with these HVAC decisions, so he and his team go above and beyond to make sure the customer is in the know, and that the job is done right. No short cuts were taken on this project, in fact they cleaned up some shortcuts that were clearly taken by the prior installers many years ago. My family an I highly recommend Vegas HVAC. We will use them going forward for all of our HVAC needs."

"Energy Star came out to do two things for us which is installing a new Smart T and balancing the duct system in our house. For the smart thermostat, they absolutely nailed it. They did it right, had no questions or hesitation (unlike some other people who tried to quote it), and programmed it correctly. For balancing the duct system though, they did it very quickly and honestly, it was not as thorough as I was hoping it would be. I was hoping they would help me reach some ducts I had difficulty reaching or identifying some ducts I could not identify. Instead, it really felt like a case of me telling them what I knew where each duct went, and if they can easily pull the lever they did -- but that is something I could have done for free myself. So between the two cases, I would call it 50-50 success."

"The 2nd floor HVAC replacement went smoothly. the 3 installers were on time, and explained what they would be doing. they were professional and completed the job on time. afterwards they explained the warranty registration process and servicing. the unit works great."
