"Excellent service from Hecomo. Technician did not try to push purchase of a new HVAC system even though there were major issues with our system, feel comfortable while talking with an advisor. Very knowledgeable, patiently, friendly and nice person, answer all my questions. Later on, we decided to replace the whole new system with fair price and wasn’t ripped off as others. Very professional and well trained technician. I will definitely use them again."

"If you want honest, straight-forward, complete, and competitive pricing for a new HVAC system, go to Bluestar Air Mechanical. Our 21-year old systems needed replacement and we began our quotation/search process. Amongst the 7 companies we inquired with, Bluestar had the most comprehensive explanation, set of offerings, and was patient with us as we completed our comparisons. John promptly and completely answered all of my questions ranging from installation, future usage, efficiency, and advice on what was necessary vs an accessory. Lynn at the office was prompt and courteous on all of my scheduling, dispatch, and payment inquiries. You'll get top notch quality, service, and friendliness if you work with Bluestar for your HVAC replacement needs."

"Everything went great. My AC died and it was close to 20 years old so I wanted the whole unit replaced. I have 4 young kids so no AC in the summer was not a pleasant option. The owner came out on site the day we called and was able to have the new unit installed the next day. I have dealt with many HVAC companies in the past as an Insurance Adjuster. These guys exceeded my expectations and were very reasonable on price. I highly recommend using Buric Heating and Air Conditioning!"
