Very thorough plumbing inspection fully complimentary for being an annual member for the HVAC side. They did dye tests on all toilets, checked sinks, and water heaters. Did water harden tests along with chlorine levels and made valid recommendations. The combination of master plumber James Harr and soon to be master plumber Matej Bzdil made the inspection quick and easy. Highly recommend and will use them again!

My old HVAC system was at the end of it's life in 2024. After a few estimates, I chose McCullough to replace it. A 2-stage 2 zone Carrier system was installed and has been a great decision. Because of problems with the original ductwork, everything feeding the second story was also replaced. The new system is very efficient, reducing my cooling bill significantly. A small problem popped up and the technician was able to diagnose and repair it very quickly.
The price was reasonable considering the extent of the work. I enrolled in twice a year maintenance and have had no additional costs.
It's a great company with well trained and considerate people. I highly recommend McCullough for installation, repairs and maintenance.

Good communication, fast and thorough work. Thomas was great- fast and thorough! Thomas also came back and made sure a drainage leak was also fixed. Highly recommended!
