Kyle Stirling was fantastic! Came out next day, got right to it, and got us back up and running quickly. I greatly appreciate Kyle also taking the time to explain what was wrong and walk me through if things were breakfix vs preventative. Thank you Kyle!

Kyle has absolutely gone above and beyond helping us with our A/C unit. He is knowledgeable, patient, and kind, which is sadly rare to find from a lot of other companies and their reps. We have been so happy with having found McCullough and the services the company/Kyle has provided!

Josh Henderson stopped by to check the status of my AC. He correctly identified the problem and fixed it. He was right on time and very prompt. I’d highly recommend McCullough’s services.

I had a great experience with McCollough HVAC during my regular maintenance service. Chris Miko was thorough, professional, and kept me informed every step of the way, explaining what he was checking and why. He identified that the system needed additional coolant and took care of it efficiently.

I was really impressed with Chris's attention to detail, clear communication, and commitment to making sure everything was running properly. It's reassuring to work with someone who takes the time to do the job right. Highly recommend Chris Miko and the McCollough HVAC team!
