Craig with McCullough came out today to service our HVAC system, and he did an excellent job. He was thorough in his work and took the time to walk us through everything he did, which we really appreciated. It's clear he takes pride in doing the job right, not just fast. Great service from a knowledgeable, honest technician — highly recommend asking for Craig!

Matej showed up same day to solve a plumbing issue that we had. He diagnosed the problem correctly, explained my options well, did great work to fix it, and helped us find a company to deal with the water damage. He really brought joy to an unpleasant situation.
