What can I say. Mike McTaggart was skilled, polite and on his game. We had no AC in the house on a 95 degree day with +90% humidity and Mike quickly diagnosed the problem and replaced a fried capacitor and got us back up and running within the hour. What a fantastic emissary for the company and what a talented professional. I highly recommend McCullough and of course Mike (a.k.a the Other Oracle of Omaha). Great job Mike. If I could leave a 6th star I would.

Ryan Lake did a great job and thoroughly explained the issues he found while repairing our system. He arrived promptly, texted us a photo so we knew who to look for, and was kind and professional. He discussed some options for improving home maintenance of our system, which we found very helpful. We trusted McCullough to install our system and we trust them to repair it!

Just ha Mccullough heating and air come over do a cooling inspection on my HVAC system that I bought from them. Super easy, fast and thorough with pictures and all of their readings. Worked with a technical named Miko that was very courteous and easy to work with. Highly recommend!
