Updated review for new HVAC installation. The team did a great job installing new ductwork and system. They were able get it done quickly and with care. Big thanks to crew member Ayden , he took the time to install my atypical vent covers and did it with care , it was very appreciated as I see them everyday.

I had a damaged and inoperable HVAC system caused by an incompetent contractor, and I needed help fast. Eric S. from McCullough was able to quickly come out and repair the damage. The quality of the work was top-notch, totally professional-grade workmanship. On top of that, he was super knowledgeable and was happy to educate me on what he was doing and why. Thanks, Eric!

Today I had an inspection conducted at my house of my water heater, water lines, water quality and pressure, toilets and tubes. I was a little afraid because of today’s pricing but am so grateful that it was done due to the findings and wonderful advise I received. James Farr is a licensed plumber and is good at what he does. I highly recommend him. I love McCullough and am grateful they have him.
