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.

Chris and Robert were easy to work with and did a fantastic job over the holidays. They replaced all of my ducts and installed a new vapor barrier in my crawl space. I appreciate the cleaner air! Thanks!

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....

Marietta Heating & Cooling FAQs

Q How often should I schedule HVAC maintenance in Marietta's climate?

A

Due to Georgia's hot, humid summers and the heavy workload placed on HVAC systems in the Atlanta metro area, we recommend scheduling maintenance twice yearly - once before the cooling season and once before heating season.

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

A
Properties in the county seat face unique challenges, including urban heat island effects from major highways and dense development, varying home ages from historic downtown to new aerospace industry housing, and the demands of Georgia's extended cooling season. Our technicians understand these local factors and tailor repair approaches accordingly for optimal performance and efficiency.

Q Do you service both residential and commercial HVAC systems?

A

Absolutely. Our experience includes residential systems in family homes throughout Marietta as well as commercial installations serving the aerospace industry and defense contractors. We understand the unique requirements of properties serving aerospace workers and the precision demands of facilities supporting Georgia's aviation sector.

Q How can I improve energy efficiency in my historic downtown Marietta home?

A

Historic homes near the Marietta Square often benefit from modern HVAC upgrades while preserving their character. We recommend proper insulation, programmable thermostats, upgraded ductwork, and modern systems designed for Georgia's climate. Properties in the historic district may also benefit from specialized indoor air quality solutions due to their age and construction methods.
