Andrew Scott
McCullough and Shawn May came through where 4 other companies failed and fixed some terrible whole-house vibrations caused by a faulty blower wheel. Shawn gave us an honest, straightforward diagnosis of the problem and attempted the lowest cost possible fix before proceeding to more involved repairs. McCullough’s team was also very responsive and made scheduling/information gathering pretty painless. Great experience overall and will definitely be calling them for any future HVAC needs!

We had a great experience working with Evan Young as our project manager. We had to do an HVAC system replacement and he was super professional, easy going, and knowledgeable. All the pricing and info was simple and straightforward and we never felt pressured by any sort of upselling or sales tactics. The team focused on what we need and everything went smoothly. Especially appreciate the follow up quality inspection a few days later to make sure everything was on point. Highly recommend McCullough!

James Welcome
I have lived in my home for 20 years and recently had for the first time, a complete home plumbing inspection by James Farr from Mccullough. The inspection report was very valuable and informative. The plumbing was in much better condition than I was expecting. I was very happy and satisfied with the report. James did a very extensive look and testing of everything. His report included understandable assessments and a game plan with options for eventual improvements. James' demeanor was very friendly and professional.. I was not pressured at all to make any kind of immediate decisions which was so appreciated. I use Mccullough presently for my HVAC service and now do the same for plumbing services.
