Best service I have ever gotten from an HVAC company. Thorough testing and explanation prior to switching components out. Matt was a great service technician. Troy was excellent and saved me money in the long run. I have used other companies in the past ...with mixed results. McCullough is now my go to company.Read More...

I recently had the pleasure of meeting Alonzo from McCullough Heating & Air, to service my HVAC system. I was very impressed by his professionalism, kindness, and consideration throughout the entire process. He showed up on time and communicated clearly ...about the issue and the solution. He demonstrated his efficiency and skill by fixing the problem in a matter of minutes. He also shared some valuable advice on how to keep my HVAC system in optimal condition and avoid potential issues in the future, because my system had a glitch. He was not only friendly and courteous, but also patient and respectful. He handled my 4 year old niece’s curiosity and enthusiasm with grace and politeness, which I really appreciated. He went above and beyond my expectations and delivered an excellent service. I would highly recommend Alonzo and McCullough Heating & Air Conditioning to anyone who needs HVAC services. They are the best in the industry and deserve 5 stars for their quality, reliability, and customer satisfaction. Thank you, Alonzo, for a job well done!Read More...
