"GAC services was able to come out for a same day trouble shooting appointment. Jim S arrived on time and was very courteous and professional. He was able to quickly identify the problem with the registers and dampers and able to get warm air flowing to the otherwise very cold areas of the house. In addition, Jim was able to recommend some additional services that would help me achieve the desired evenness of temperature such as an additional return and humidifier for the home. Great experienced master certified technician!"

"I contacted Bluestar Air Mechanical for a second opinion after an appointment with Air One. I have a Carrier HVAC system, and the Air One technician recommended a complete system replacement, claiming the blower was bad, the furnace control board needed replacing, and that there were other issues. Since replacing the HVAC is a big investment, I wanted to get a second opinion. It was only after comparing the service from Bluestar that I realized Air One may have been pushing for a new system sale or lacked the expertise to properly diagnose and repair the actual problems. Isaac, the technician from Bluestar, spent about an hour thoroughly diagnosing and fixing the issues. He found burnt wiring in the furnace and discovered that the wrong capacitor had been incorrectly installed in the AC. Isaac replaced the burnt wiring in the furnace and the capacitor in the AC. After these repairs, my Carrier system was back up and running—without the need for a costly replacement. Bluestar, and Isaac in particular, demonstrated professionalism, expertise, and honesty. They focused on resolving the actual issues instead of pushing for an unnecessary system replacement. I highly recommend Bluestar for their reliable service and Isaac’s thorough and knowledgeable work."

"I called a few HVAC companies on a Saturday morning, due to my A/C only blowing cool to warm air. After speaking with a couple of other companies that advertised as providing 24/7 service, Blue Dot was the only company that would come out on that Saturday. The technician that came out was named Dwight ("DJ"). DJ was exceptional! He took the time to explain what he was doing and why it was necessary. He also provided tips on how to maintain the a/c unit to keep it running efficiently. He was courteous, professional, and patient with answering my questions with a positive attitude. He repaired the unit during the visit. DJ turned a stressful situation (worrying about the possible repair) into a smooth and reassuring experience with his expertise and positive attitude."

"The company was responsive and provided excellent service at a competitive price. Our old A/C and furnace had to be replaced in the heat of the summer. Mr. Douglas was quick to respond and provided a prompt estimate. He meet all promises for scheduling installation, removing the old equipment, and a quality installation of the new equipment. He followed up to insure the system was functioning and that all was well. We were completely satisfied with the new system, the installation and the customer service. We highly recommend this firm!"

"After having a very bad experience with another HVAC company, I used them and quickly saw how the other HVAC company was over charging. I found my technician to be very knowledgeable, hardworking and honest. He repaired one AC unit and replaced the other. Would definitely recommend!"

"It went very well. They did a good job. The cost was over $400. I don't know whether or not that's too high or not. I seldom have plumbers in so I can't say the cost was high, although I was surprised it was $400, but that could be the going rate. He seemed very agreeable and very happy. I needed something and he was happy to get it. He was very knowledgeable and helpful in that regard. As for the quality of their service, so far so good. Everything went okay. It stopped leaking."
