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.

When Your HVAC Problem Cannot Wait

Some HVAC issues can be monitored for a day or two. Others simply cannot wait. If your system has completely shut down, is making alarming noises, or your home is reaching unsafe temperatures, that is an emergency. Georgia summers can push indoor temperatures to dangerous levels within hours of an AC failure, and winter nights in the greater Atlanta area can get cold enough to put vulnerable family members at real risk.

You should not have to decide whether your situation is serious enough to call. If something feels wrong with your HVAC system and you are uncomfortable or concerned, call us. We would rather come out and tell you it is a minor fix than have you sitting in a home that is 90 degrees at 10 PM wondering if you should have called sooner.

HVAC Emergencies We See Most Often

After more than 20 years serving Dacula and surrounding communities, we have seen the situations that tend to send homeowners reaching for the phone at all hours. Here are the most common HVAC emergencies we respond to:

A complete system shutdown on a hot or cold day with no obvious cause
Warm air blowing from the vents when the AC is set to cool
Ice forming on the refrigerant lines or outdoor unit during summer
A burning smell or unusual odors coming from vents or the unit itself
Loud banging, clanking, or grinding sounds from your indoor or outdoor equipment
Water pooling near your air handler or indoor unit from a clogged condensate drain
A furnace that cycles on and off repeatedly without heating the home

Dacula’s humidity adds another layer of complexity to many of these issues. High moisture levels common in Georgia summers can push your AC system harder, accelerate wear on components, and increase the likelihood of refrigerant problems, drain clogs, and coil freeze-ups. When a breakdown happens during the most humid stretch of summer, it tends to hit harder and faster.

Steps to Take Before We Arrive

While you wait for our team, there are a few simple things you can do that may help protect your system and your home.

Check your thermostat settings to confirm it is set correctly and the display is working

Replace or check your air filter if it looks clogged, since restricted airflow is a common cause of system failures

Check your circuit breaker panel and reset any tripped breakers related to your HVAC system

Turn the system off at the thermostat if you hear strange noises, smell burning, or see ice forming on the un

Clear the area around your outdoor unit if anything has fallen on or around it

If you see standing water near your air handler, turn the system off to prevent further damage

These steps will not always fix the problem, but they can prevent a manageable issue from turning into a more costly one before we get there.

Frequently Asked Questions

What counts as an HVAC emergency?

Any situation where your home is reaching unsafe temperatures, you smell burning or gas, or your system has completely stopped working is worth an emergency call. When in doubt, call us and we will help you figure out next steps.

How fast can you respond to an emergency HVAC call in Dacula?

We prioritize emergency calls and work to get to you as quickly as possible. Our team serves Dacula and the surrounding area, so response times are typically faster than you would get from a larger regional company dispatching from farther away.

Will I pay more for emergency HVAC service?

We believe in upfront, honest pricing, and we will always tell you what to expect before any work begins. Our goal is to make sure you understand the cost so there are no surprises when the job is done.

Should I turn my HVAC system off while I wait for a technician?

If your system is making loud or unusual noises, producing a burning smell, or you can see ice forming on the unit, it is best to turn it off at the thermostat. This can prevent additional damage until we arrive.
