Chris is an awesome person to work with. He fixed our outdoor unit in a snowy day when nobody else could come. Reasonable price and quick turnaround. Would love to work with him again.

Great team! Fast and efficient response. They were able to diagnose the problem and repair rates reasonably competitive. Their customer service was excellent!

Good people. Came out to install some neat thermostats and found other issues that they didn't charge me for. Highly recommend

Excellent response times and communication. Chris was wonderful to work with. We had some minor repairs done to a relatively new unit, and Chris worked hard to make sure the parts were covered under warranty. Cost of labor was very fair, and we will definitely be using them again in the future....

Kennesaw Heating & Cooling FAQs

Q What makes AC repair more challenging in the Kennesaw area?

A

Properties in this part of Cobb County face unique challenges, including urban heat island effects from major transportation corridors, varying home ages from historic downtown to new university-area construction, and the demands of Georgia's extended cooling season. Our technicians understand these local factors and tailor repair approaches accordingly.

Q How can I improve energy efficiency in my Kennesaw home's HVAC system?

A
Georgia homeowners can significantly improve efficiency through regular maintenance, proper insulation, programmable thermostats, and upgrading to modern systems designed for our climate. Properties near busy areas like Cobb Parkway may also benefit from enhanced air filtration to reduce system strain from environmental factors.

Q Do you provide HVAC service for both older and newer homes in the Kennesaw area?

A

Absolutely. Our experience spans from historic homes near the Kennesaw Mountain Battlefield Park to modern constructions around Kennesaw State University. We understand the different approaches needed for established neighborhoods versus newer developments and adjust our service methods accordingly.

Q What should I do if my heating system fails during a North Georgia cold snap?

A

Contact MR. HVAC immediately for emergency heating repair service. While Georgia winters are generally mild, occasional severe weather can strain heating systems, especially in older homes. Our emergency technicians are equipped to handle urgent heating repairs throughout Cobb County when your family needs warmth most.
