What Your Neighbors Are Saying About Us

My technician was knowledgeable and respectful. I even asked him to tape up a seam in the air duct area and he did so. He noticed that the filter was not the same as they normally put on but then he found out that the owner had a stack of them there to replace at the 3-month interval. They were lesser quality but that was what the previous owner had changed on the 3-month interval.

Fantastic experience! Our heat wasn’t working, and Mandi was able to get a technician out to our house later that same day. Jason was our technician, and even though it was late in the day, he was kind, patient, and thorough in making sure we were up and running again. 10/10 would and will recommend!

My heating system suddenly stopped working, and this company once again proved why they’ve been my go‑to since 2010. The technician arrived quickly, diagnosed the issue on the spot, and had the faulty part replaced within two hours of my call. Fast, knowledgeable, and consistently reliable — I wouldn’t trust anyone else with my HVAC needs.

From the very beginning Mandy took care of me and fit me into their busy schedule. She kept me informed of when someone would be out. She's awesome! Jason also, went above and beyond!! No matter how long it took him to figure out this dual fuel heating, he stayed until then! Thank you Jason for all your knowledge and help!! You rock!!

Hands down, a great experience with Hero AC! The team was attentive, professional, and answered every question we had. From the phone call to the moment they left our home, they guided us through the entire process with care. You won’t be disappointed working with their company.

Common Signs Your HVAC System Needs Repair

Catching a problem early can save you from a bigger repair down the road. Here are some signs that your HVAC system may need attention:

Your home is not reaching the temperature you set on the thermostat, even after the system has been running for a while.
You are noticing unusual sounds like banging, rattling, grinding, or squealing coming from your unit.
Your energy bills have gone up without a clear reason, which can point to a system working harder than it should.
There is weak or uneven airflow coming through your vents in different rooms of the house.
You are smelling something musty, burning, or otherwise off when your system runs.
Your system is short cycling, meaning it turns on and off more frequently than normal.
There is visible moisture, ice buildup, or leaking around your indoor or outdoor unit.

If any of these sound familiar, do not wait. A small issue can turn into a much larger one if left alone, especially during the peak of a Georgia summer or a cold winter stretch.

We keep things simple and transparent from the first call to the final check. When you contact Hero Heating and Air, here is what you can expect:
