"Could not recommend this company more to help you with whatever you HVAC needs are. Knew I would need to replace my A/C system at some point and that day finally came. Absolute Comfort was there the next day to give me a quote. I chose to get a full system (AC & Furnace) and their price beat a quote from another company by $1,500.. and the competitor quote was for only the A/C. The installers were professional and personable despite the attic being extremely hot on the day of installation."

"Great experience with MaBreeze HVAC! They were professional, knowledgeable, and did a great job from start to finish. They showed up when they said they would, took the time to explain everything, and made sure the job was done right. It’s hard to find companies that take pride in their work and actually care about their customers, but MaBreeze HVAC definitely does. I highly recommend MaBreeze HVAC to anyone looking for honest, reliable, and quality HVAC service!"

"I called GSM inquiring about their HVAC and insulation services. I also asked if I could have someone perform a Manual J load calculation (surprise to me, the Manual J calc was free!) as I felt that my existing heat pump was sized too small for my home (2.5 ton dual-zone single stage heat pump for 2200sq ft 2-story house). We agreed on an appointment time, and they sent Kelly out to my house. Kelly was very nice and professional, and did a thorough job explaining what all could be done and what my options were. Due to having so little room to work inside of the mechanical closest, you would have to remove the air handler completely just to wrap all of the duct work. Since I would be removing the old air handler that was 8 years old anyway, I decided to replace the entire system with a new Amana 3-ton 18 SEER dual-zoned heat pump. Kelly also told me they could seal up the hole & the mechanical closet so that hot air could no longer enter that space as well. I agreed to their quote, and they came out a week later (it would've been sooner but GSM wanted to make sure that the new system was designed properly, so they had to architect and design the layout of the new equipment to fit the small space) to do the work. Owen and Jason came out to perform the installation. They were both very professional & thorough, and they did an excellent job with the swap out & installation of the new heat pump. When GSM told me that it would take two days to do the work, I was prepared to be miserably hot trying to sleep at night with no air conditioning. Not only did GSM bring a portable AC unit for me use that evening so that wouldn't be the case, Owen and Jason actually got the heat pump wired and working the first day so I had full AC that evening, and the portable unit wasn't needed! They also insulated the attic space & mechanical closet with spray foam and foam board so the hot attic air will no longer be an issue. All in all, my experience with GSM has been great! They've been easy to communicate with throughout the entire process, they did an excellent job with the installation of the new equipment, and now I can rest easy knowing that everything has been taken care of!"
