On time arrival. Issue with Thermostat fixed within 30 minutes and the heating system was running again. Guardian sent a text with the technicians picture and short bio prior to his arrival which made us comfortable about the experience level. Overall a great experience with Billy from Guardian

Great company, very professional

During a routine maintenance call, I was told by another company...one I had been doing business with for 20 years, that I needed a new unit. I had Atl.Air Authority come out to give me an estimate. They inspected the unit and advised that it was in good working order. Recommended another maintenance inspection in spring, just to be sure I was ready for summer. I was beyond relieved. I had been shocked by the other recommendation, since the unit was working beautifully. But, they had said it was in all kinds of trouble. Thank you Atlanta Air Authority

Excellent work and professional

Jade was very responsive to our call. While they were here they took time to explain things we did not know about heat pumps, and they diagnosed our problem very thoroughly. Our system is now working as it should and their charges were very reasonable. It is hard to find someone who knows heat pumps well and does good work. We are very happy to have found Jade and will sign up for a maintenance contract with them.

From the appt. set up to the completion of the job- precise, polite, cost effective, knowledgeable and a correct solution.
