Mike did an awesome job - he came out last minute on a national holiday and got our AC back in shape in no time at all.

5/5 Would definitely recommend.

McCullough Heating and Air has been an outstanding company to work with. They are responsive and fair. In particular, Jaiden, a recent technician gave great customer service on a repair issue.
