“I recently had a HVAC system installed! Kevin and his crew were very professional and they did a wonderful job! I HIGHLY recommend their services! My old compressor was encaged. They removed the cage. The job was done so well, I can't even tell a cage existed previously!!!”

“What a time for my AC to not cool! Nathan got here quickly, found the problem, ordered the part, and had it fixed before his estimated date. No need to look any further for a serviceman, they get the job done quickly and efficiently. Great Job!”

“Chances are this amazing family owned business has been taking care of the AC/heater in your house for the past 20+ years already. They take good care of you. Just give them a call- price is right and the people are kind and skilled. My choice in Waco hands down.”

“These guys are great! I’ve used them since their father (grandfather for some of them) started this business back in the early 70’s. Good people, good work, fairly priced and a family business. With the reputation that all too many AC companies in Texas give this family a shot at doing things right.”

“I cannot say thank you enough to the team at McMullen Services for providing quick, friendly service and ensuring my HVACs were ready for winter and installing two smart thermostats. They were super communicative, always on-time and provided a lot of knowledge on the system. Thanks for answering all of my questions!”
