I've been using McCullough for years and they are always prompt, friendly and do a great job. Unfortunately this weekend the condenser fan motor on my unit died. When I called, an actual person answered even though it was a Sunday morning. It sounded like they would've been able to send someone the same day if it was an emergency but I opted for the first time slot Monday morning. Craig showed up promptly at 8 am (and called shortly before) and took about an hour to diagnose the issue and replace the old rusty fan. The replacement was a tad expensive (a programmable, capacitor-less motor that could replace the motor on a variety of units) but Craig made short work of the replacement and also blew out the drain for no extra charge. Everything is working great now and I would recommend McCullough for their prompt and friendly service.

The McCullogh team is amazing! From the customer service, to the ability to text, to the same day scheduling, ability to have inventory of units, to the technicians that know their stuff. We've been so pleased. Special shout out to Clayton who came yesterday to problem solve a leaking AC unit. Fast, helpful, polite, and FIXED! So thnkful!

I would highly recommend using McCullough, specifically Jeff. I recently used them for an AC/heat inspection and they inspected my whole system and did a fantastic job. Jeff located an issue in my system and was able to repair it on the spot for a great price. He likely saved me thousands had the issue gone unchecked. Thanks Jeff! Update March 2026: My AC was taking a long time to cool my home, so I called McCullough again. Kyle came out and diagnosed the issue, laid out my options and prices. He did a great job fixing my problem. Glad I called them again. Thanks Kyle!
