"Chris was amazing. My A/C went out on a 90-degree Sunday. not only did he answer the phone, but he came to my home in a few short hours. He checked my home and unit, found and repaired the problem the same day, even though he had to return after allowing time for ice buildup to defrost. He is prompt, efficient, knowledgeable, courteous, and friendly. All this plus reasonable fee for coming out on a Sunday. It was so refreshing to have an actual human answer my phone call rather than a machine.

Thanks Chris, I will definitely recommend you to family and friends!!"

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.
