Shawn was professional and a good guy. He gave excellent explanations of the condition of my unit and told me to contact him if anything came up. Good experience.

I would like to briefly share my experience for HVAC with Mccullough Heating & Air Conditioning. I had done lot of research about different system and it took me a while. But finally decided to go with this company. I would like to acknowledge the great service provided by Evan Young their Senior Project Manager who helped mpe from the start to finish of the project. Also, their installation team was great in installation providing a smooth experience.

I appreciate the pro tips she offered and for making it easy to act on her advice by sending me limks for to any products she recommended. Im always pleased with Mcculloughs techs but Makayla def stands out for her willingness to go above and beyond . Thank you!
