WHAT YOUR NEIGHBORS ARE SAYING ABOUT US

Leticia Paredes
I have been using McCullough Heating and Air to provide my twice yearly maintenance for nearly 3 years. During the last 2 months I have had my unit serviced by Vlad for a drain clog and recently Jared for my annual maintenance. Both technicians did a great job and spent time servicing my unit despite that it happened to be late in the day. Both were professional in their demeanor and engaging. I would have to say the same for the past technicians who have serviced my a/c unit. I would also offer that I have been impressed with the thorough maintenance service that McCullough provides,

Been using McCullough for a few years now, mostly just for annual maintenance. Staff is always helpful and responsive and pricing seems to be competitive. Blake has been my service tech a few times now and I really appreciate his professionalism and friendliness.
