Our AC wasn’t cooling in this ridiculous 100+ heat. We were able to get a same day appointment and Jaiden diagnosed and corrected the problem. He’s very knowledgeable and professional and we are very grateful our unit is cooling again.

James Farr, a master plumber, did an exceptional job troubleshooting and repairing an exterior plumbing leak that I had in scorching 100+ degree weather. His professionalism and thorough explanation of the issue were truly commendable. I highly recommend James and the McCullough team.
