HVAC experts for residential & commercial properties

We're the heating and air conditioning company that cares. We've been fixing heating and air systems in Northwest Georgia since 1991 and we have the testimonials to show that we know what we're doing. We diagnose and fix your problem fast.

Marvin McCullough is the best around hands down. He will treat you right and is the most honest person I know. Also he's a devoted Christian. Just give him a call.

Our Mission Statment

McCullough Mechanical Services works to raise the standard for home and commercial heating and air systems. We make your building feel like home without charging you an arm and a leg. We seek to make your space more comfortable, and we don't try to sell you equipment that you don't need at a price you can't afford.

We Offer:

  • Fast response times. You won't have to wait around on us.
  • Reliable work. We build it to last, none of this "build once, repair again" crap
  • Friendly, knowledgeable, professional technicians who respect you
  • The best equipment. We're certified dealers of the most respected brands
  • Solutions for every budget. We even offer financing!

Our Goal and Vision

We are on a mission to make your building more comfortable. This means we can repair your HVAC unit, install a new one, or just come out for an inspection to discuss your options.

We want to go above and beyond to serve our clients in northwest Georgia (and, sometimes, beyond). We want you to have such a good experience with us that you can't help but tell everyone you know.
If you'd like a free consultation, use the forms to send us an email, or give us a Call at 706-266-2944.
