"Sunday 6/22 my mom's air conditioner was struggling. We called Aireserv who set up for their tech Bryson Bean to come out to mom's house. From the bright greeting smile as he introduced himself to the going over everything he was very professional and patient with all my questions. Highly recommend Aireserv for any of your heating and air conditioning issues. Thank you Bryson for being so you and personable."

"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. "

"Good morning. We woke up yesterday with no heat, brrrrr. So we looked for a local business and we found this company. Mike came out the same day, the part we needed was around the airport he got it, came here this morning at 7:30, like he said and we now have heat! Mike is honest, reasonable and a man of his word You will be glad you called him. I am so glad we did. "
