Unlimited Maintenance has been our exclusive HVAC provider for almost 10 years, from annual maintenance to replacing parts or or installing new units and duct work in a basement remodel. The service is always friendly, prompt, quickly implemented and affordable.

Sean and his crew did a great job replacing the A/C unit at our home. They were very professional and got the job done right in a timely manner. All the work was done at a fair price that was much lower than two other high-rated companies that gave bids. I highly recommend Maintenance Unlimited!

Sean came out swiftly to diagnose the issue with my HVAC unit. He's a pleasant personality who takes the time to listen to your concerns. He found and repaired large gaps between the pieces in my unit which the original installers had left unsealed. I recommend Maintenance Unlimited for their quality, fast service & kindness!

Maintenance Unlimited Atlanta replaced both of our home's AC units with our 100% satisfaction and expectation. The technicians came to our house 3-4 times to check on some minor concerns and adjustments during the warranty period. Every service call was free of charge and prompt.
