Meet Maintenance Unlimited Heating & Cooling

Maintenance Unlimited Heating & Cooling was founded in 2001 by owner Sean McKinney in Atlanta, Georgia. Since the beginning, our company has been committed to the principle that a quality heating repair resource should be easy to reach, dedicated to listening to the needs of our customers, and perform at the highest level of professionalism—offering exceptional workmanship and customer service.

We know there are many heating and air conditioning companies in Atlanta, and it can be hard to know which one to choose. You must consider both price, quality of service, and the reputation of the company you are considering working with. At Maintenance Unlimited Heating & Cooling, we are confident our reviews speak for themselves—and we have glowing relationships with the Better Business Bureau, Kudzu, and Angie’s List. Since our conception, we’ve grown one heater repair job at a time thanks to our customers continuing to recommend our services to their friends and family, and we are ready to put our expertise to work for you.
