"They installed central heating and air in our home in 2025. They were efficient, did a excellent clean up, and friendly. They checked in a week after to make sure we were satisfied with the system and if we had any questions. We are extremely satisfied with the new system. The controls are easy to work and the system is very quiet and efficient."

"Romano's HVAC and electrical was very prompt, efficient, and fair priced. They diagnosed the problem and fixed my AC unit problem with no problem."

"For the most part we are satisfied with the purchase. There were some hiccups with the installation that kept us from being completely satisfied. If there was better communication with the install process it would be helpful. HVAC is a large purchase with little to show for it because its in the basement or attic so the better informed you are will make it more comfortable. Otherwise we got the feeling they can just hide any of the problems they encountered because the customer wont see it anyway."

"They used the part I had at the house to fix it. I bought it about a year ago, and had never put it in. I called them, and they came out to put the part in. It is working ok now. I have been using this company for 15 years now."

"Repaired my AC instead of replacing it, which everyone else wanted to do. Saved me thousands of dollars."

"I've worked with Sierra Pacific on two projects now, solar heating for my pool and HVAC duct changes due to another companies improper installation. I am very pleased with the quality and professionalism of the technicians and office staff that supported both of my projects. I highly recommend Sierra Pacific for all your HVAC and solar system needs!"

"I met Jesse (owner) at the Auburn home. After setting an appt., he showed up on time as promised (can t say that for a lot of other companies). We reviewed what I wanted done which I appreciated because I ve had others suggest what they wanted done instead. He physically went up into my attic to access my old and inefficient insulation, including video recording it. He also spent time looking at my old windows (1980 s style) that I was also looking to replace. Jesse came up with the cost which was thousands of dollars cheaper then the several other estimates I have received. After agreeing on moving forward, Jesse played an active part in the entire project. He even provided me with his cellular number and always got back to me when any questions arose. The workers who came to install the insulation were very friendly and professional (I continuously talked to them, probably annoyingly). They took their time to assure that everything was done as promised and I even double checked their work. The next part of the project included a new slider and several windows. Jesse was on scene throughout the window installation and the final product was fabulous. Craftsmanship was impeccable and the windows and slider look great. Even after the project was complete, Jesse has contacted me to assure full satisfaction was met. I would recommend Clear Efficiency to anyone."

"I requested a quote from Angi's list and was contacted by telephone within minutes. An appointment was set for the next day. The contractor showed up on time, repaired our problem and gladly completed extra work that was not originally scheduled. I would definitely use this service again."
