I recently had the pleasure of having Darren from Mauzy Plumbing, Heating, and Cooling for an air conditioning tune up, and I couldn’t be more satisfied with the service. Darren was incredibly personable and made me feel at ease right from the start. His professionalism was evident in the way he conducted himself and communicated throughout the process.Darren’s knowledge about air conditioning systems was impressive. He quickly diagnosed the problem and explained the necessary repairs in a way that I could easily understand. His courteous demeanor and respect for my home further highlighted his commitment to excellent customer service.Overall, Darren’s exceptional service made a potentially routine tune up smooth and worry-free. I highly recommend Darren and Mauzy Plumbing, Heating, and Cooling for anyone in need of reliable and top-notch HVAC services.

Robert is an excellent technician. He asked for some information about the a/c unit, did an inspection, and quickly discovered the problem. He provided a repair estimate and offered some information about replacing the unit as it is very old. He finished the repair quickly, tested the system to make sure it was working, and provided a list of options for the future. I would rate the overall experience as excellent.

Robert was very professional, courteous and knowledgeable. He explained in simple terms what he was doing and why. He found the problem and repaired them while explaining why the air was hot not cool. Robert gave us excellent customer service and more than anything his honesty and integrity because we were told that we would probably need a compressor and tune up a couple of years ago. Robert is an excellent representative for Mauzy. Thank you for your excellent service.Sandra Robinson
