We very much appreciate the excellent and timely service provided by tech Marco Lopez and the McCullough team this week when our 2 year old Carrier A/C system couldn’t get us below 82 F.
Marco quickly determined that there was coolant leak in the evaporator coils. He immediately ordered the replacement coil assembly which was delivered to us within 2.5 hours. Marco then returned and proceeded with the replacement operation and then (holding an umbrella in the rain) did the outdoor work to recharge the system with coolant before resealing the indoor unit and thoroughly verifying that it was operating correctly.
Thank you, Marco and team for an ideal response to our emergency!

I’ve been a long-time McCullough customer and this spring I needed to replace my HVAC system. Evan Young, Sr. Project Manager did calculations at the house and provided several new system options. Evan also suggested adding another air return to increase the air flow for better system performance. And this feature was not a big cost —$100.
Evan was great to work with, quite knowledgeable about HVAC systems, and answered my questions.
The installers arrived on time and worked hard to get everything in place. I’m glad I added the extra return.
I am pleased with McCullough’s people, quality services, and emphasis on customer satisfaction.
