"My AC failed and I had limited time to find a good solution, I made a phone call to Relax HVAC based on the online reviews and it was a great decision. Nasser came to check the situation, he gave a very detailed and comprehensive overview of the situation and provided with the options I had. I decided to replace the unit, Nasser went above and beyond to find a unit delivery service but there was nothing available over the weekend so this gentleman went for unit pick up himself and finished the installation within a day from my initial call. Moreover, the provided price was very reasonable.I can't be more happy with the outcome and highly recommend Relax HVAC"

"Fast service! They came within an hour of my call. Spent over 2 hours diagnosing the problem. Spoke with Trane to confirm his findings. Then came back 3 days later with the faulty circuit board which was covered under warranty. Price was less than I expected and the gave a discount because I am a veteran. I highly recommend this company!!!"

"Team did a great job, and didn’t try to upsell me. They diagnosed and replaced the leaking pipe - a competitor tried to use the leak as an excuse to sell me on replacing the entire boiler as the only way forward. Appreciated JDL’s focus on addressing the issue at hand. They also tested and confirmed existing boiler had years of life left in it."

"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."

"The Company is untrustworthy with their Prices. They offer no detailed Invoice, and their charges are A LOT more expensive than other Companies, to the point where I had to file a formal complaint with the BBB. Never again."

"He responded quickly and noticed that my water heater was only 3 years old. He contacted the provider and not only got it replaced at no cost...which involved getting a local retailer to forego the price for my model which they no longer carried. Speaking on my behalf was above and beyond what i would have ever expected him to do. His price was fair and he came out on the weekend. He corrected installation errors from the previous installer and was available to me after the install should i have questions. He was kind and patient in what was a stressful situation due to other issues going on at the same time. I am forever grateful to Darrell."
