Our Mission Statement

“To provide our customers the best possible service and highest quality installations, in a manner that will encourage them to recommend us to others.”

Efficient Comfort Solutions Since 1971

Knight Air Conditioning and Heating Company was founded in 1971 with the vision of providing professional service and installation of heating and air conditioning systems for the home and business owners of northeast metropolitan Atlanta.

Today, over forty years later, we are providing high efficiency replacement systems for many of our original customers as well as for the hundreds of new customers we have added year by year.

We have been able to retain and build on our customer base by being a company that promises what we will do; doing what we promise; and guaranteeing customer satisfaction.

This environment of steady growth has enabled us to attract and develop a team of quality employees, dedicated to the training and work ethic necessary to deliver a high standard of service to our customers.   Out of this desire to be the best we can at what we do evolved our mission statement

With this business philosophy we have seen our company grow year after year, with most of our growth coming by personal referral – one satisfied customer relating their satisfaction with our company to another friend, associate, or family member.

Many of our referrals come from architects, engineers, and utility company employees for whom we have performed service and installations.  They know they can count on Knight to deliver the quality and attention to detail they expect their friend or associate to receive.

Our Happy Clients

“You have always responded to our needs in a professional and timely manner while paying attention to the smallest detail. Needless to say, I have recommended without reservation, Knight Air Conditioning & Heating to many of our friends and business associates. You are an excellent example of putting the customer first!”
Otis, Buford, GA
“When we decided it was time to replace our furnace and a/c system, we were referred to Knight Heating and A/C. Joel came to our home and didn’t just quote us new equipment like the others we had spoken with. He took the time to evaluate our needs and recommend a solution that led us to purchase a new Trane system which has kept our home very comfortable with it’s quiet and efficient operation.”
Mike, Grayson, GA
