"At first, I thought it was a burst pipe from the week + freezing temperatures but I needed a garbage disposal replacement. They were very responsive. Codey, the technician, was very polite and professional. I was referred by a neighbor who has used them for years. I am very pleased with their service. Mary Collins"

"Nick Bull of Tim Kyle HVAC did an awesome job. Diagnosed the problem quickly, performed the service, explained everything clearly and all at a reasonable price. I entered into a service contract and scheduled mote maintenance work for next week. Highly recommend the Company in general and Nick specifically!"

"They installed our AC system; that went fine. But several years later, when it needed repair. They came out and looked at the problem, and then ghosted me. They didn't return my multiple calls. When I finally got somebody else to come out to look at the problem, they told me that the warranty had just expired on the part that needed replacing. Putting 2 +2 together, Buric ghosted me to run out the clock on my warranty for the repair of the product they installed. Would you ever hire anybody who behaves like that???"

"DC Area - Presidential Heating. We have a two-zone system to cover basement+first floor and separately the second floor and both failed, unbelievably, within a few days of each other while on a trip. Late morning on a Sunday I googled emergency HVAC and saw all these 2 star companies and then I saw an impossibly high rating for Presidential Heating and that they don't charge extra for weekends. Ayite (fantastic) came out and fixed both systems and they were way more than reasonable. And now we have heat upstairs and downstairs! yaaaaaaaa. Our previous HVAC company got their scruples from the Sopranos while Presidential is a godsend."

"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 would strongly recommend against using this company. Michael Bonsby sold me an HVAC system that repeatedly malfunctioned between its installation in August 2022 and removal in October 2025. Over those 3 years, Bonsby had ample opportunities to identify and correct the defect in the system, but it failed to do so. Nor did Bonsby ever offer to replace the system. In fall 2025, after years of frustration, I requested that Bonsby refund my purchase price for the defective system. Bonsby has refused and, in doing so, made arguments that are materially inaccurate as to the facts of the matter and applicable law. "
