“Chris Leach did an outstanding job of providing clear HVAC system replacement specifications and prices. Carlos Reinado and Henry Alvarado installed our new system expertly and kept us constantly informed about what they were doing and why. And throughout our estimate and install process, Sam Burke gave us expert customer service support. We’re now working with SSI on a few minor follow-ups. Overall, a great experience.“

“We just moved in and Air One replaced our broken air conditioning and furnace. Dariush is a success story of an immigrant who came to America and became successful. Hard work and attention to detail paid off. Highly recommending you call his team and get your HVAC fixed right and safely.“

“The service provided by Emanuel Trejo, KP Pham and the front office staff was extremely professional and helpful throughout the entire process.“

“Payam was prompt and professional. He was very knowledgeable and took the time to explain the issue with a sensor that needed to be replaced. He had the part on hand and was able to make the fix in about an hour. The same day service was much appreciated. Highly recommend.“

“Recently needed to have a new HVAC system installed. I got multiple quotes from companies and decided to go with Mann-In based on neighbors reviews and my research. The salesman Aaron was top notch. Very response to any questions I had and the quote was very detailed. He was the only one that stated I need to have a new liquid line installed because my current one was too small. I’m coming off R-22 system. From what I gather yes the one I had would have technically worked but it was recommended to upgrade. The install crew that came was exceptional. They were on time and each was very knowledgeable and polite. They took the time to do a nice install and it shows. So glad I chose this company for my install. Highly recommend Mann-In for HVAC.“

“I cannot recommend Hava Tech highly enough. They do awesome work, staff is all very professional, punctual, and their work is very well done, efficient, and buttoned up. Incredible value, money well spent! So glad we use them for our warehouse mechanical / HVAC definitely the right team for the job.“

“They got the job done. It took them 3 trips, but it was a warranty repair so I was ok with that. The techs were professional and knowledgeable. One star taken away because when I talked to the scheduler, about the issue with my attic furnace, I told him that it appeared the ignitor was bad and I gave him the furnace make and model number and requested he pass the info to the tech coming to repair the furnace so he has the correct ignitor. He assured me they have plenty of ignitors. Well, you can guess what happened... yup, he did not have the correct ignitor. That required 2 more nights without heat in the upstairs. Another tech came, replaced the ignitor and discovered that the circuit board was also bad, which required another day to get the new board and they installed it the next day. Rick was great and got the job done. I would call them again to work on my equipment.“

“If you want competence and knowledge, call Alpha Aire. 24 degrees outside with no heat. Scott had it working in record time. He came highly recommended ~ I highly recommend him to you. I am ashamed to say I rarely take the time to write reviews. This man deserves 5+ stars!!!“
