WHEN YOU CALL
When you contact O’Callaghan, one of our courteous staff will determine exactly what kind of help you need, whether it’s a free in-home consultation or an emergency repair. Then, we’ll quickly get one of our trained, licensed, knowledgeable technicians on their way to you. Since we’re based right here in Atlanta, we’ll arrive promptly with all the information, tools, and supplies we need to help resolve your question or problem correctly the first time. We’ll provide a free estimate before committing to any work, and we’ll keep you informed each step of the way to make sure you know what we’re doing and why – and how much it may cost.

TRANE
Most people are familiar with the legendary durability and reliability of Trane HVAC systems. What many people don’t know is that Trane’s systems are exceptionally energy efficient, making them an excellent “green” choice as well as one that can lower operating costs significantly. In addition to being a Trane certified dealer, O’Callaghan Heating and Air is a Trane Comfort Specialist company – a designation given to only the top ten percent of Trane dealers. We are also proud to carry Amana and Carrier systems, helping us provide the right system for each situation.
