What Your Neighbors Are Saying About Us

They always treat me well. They're always on time for appointments. I appreciate the knowledgeable technicians--especially Fred! If you're looking for someone to service your unit I highly recommend this company.

I have used Ace & A Heating & Air Conditioning for over 10 years. I fired the rest and hired the best. They have always been courteous, and professional. They have replaced both my heating and air conditioning units. Installation techs. very thorough and professional. Clean-up 5 stars. Office staff 5 stars and roses.

A year and a half ago they installed a complete new system for us. I needed them back today to take care of my poor upkeep of it! They were fantastic both times! They came relatively quickly and were extremely thorough. Today Jermaine checked off all the boxes and then some. He made sure every aspect of our system inside and out was in great working order.

We have been with Ace & A for over 15 years and continue to have great service! Everyone at the office is friendly, helpful, and knowledgeable. We've liked all of our technicians over the years, but Fred, who has serviced our systems for the past handful of years, is absolutely wonderful! He's very honest and knowledgeable and so friendly at our appointments. We highly recommend Ace & A to anyone who needs service.

When we bought our current home, we signed up for Ace & A's annual maintenance agreement on the recommendation of the previous owners and have had very positive experiences with them. What I like best is I can email them if something comes up outside regular business hours that needs prompt attention but is not an emergency, and they respond very quickly and put me on the schedule for the next business day.

First thing Monday morning, I got a call back telling me the part had been ordered and was being delivered the same day. Before the end of the day, the technician came back with the part and installed it promptly and professionally. They also answered my many questions and were very professional. Definitely going to use this company again.

What Counts as an HVAC Emergency

Not every HVAC issue needs a same-day call, but some situations genuinely can’t wait. If any of the following are happening in your home or business, it’s time to call for emergency service.

Your system has stopped working entirely during extreme heat or cold.
You smell burning, gas, or something unusual coming from your unit.
Your home can’t maintain a safe temperature for children, elderly family members, or pets.
You’re hearing loud banging, grinding, or screeching from your system.
You notice ice forming on your unit or refrigerant leaking.

When in doubt, call us. We’d rather you reach out and find out it’s a minor fix than wait on something that could cause bigger damage or put your family at risk.

Our 24/7 Emergency HVAC Repair Services

HVAC systems don’t wait for business hours to break down, and neither do we. Ace & A offers 24/7 emergency service for both residential and commercial customers in Decatur and the surrounding Atlanta area. Whether it’s the middle of the night or a holiday weekend, a trained technician is available to take your call and get to your property quickly.

Every technician on our team undergoes annual factory training, so whoever shows up at your door knows exactly how to diagnose and repair your system correctly, the first time.

Common Emergency HVAC Failures We Respond To

We’ve seen just about everything over the past 50 years. Some of the most common emergency calls we respond to include:

Complete system shutdowns in the middle of summer or winter.
Refrigerant leaks that cause the system to stop cooling.
Frozen evaporator coils from restricted airflow or low refrigerant.
Failed blower motors that stop air from moving through your home.
Tripped circuit breakers or electrical failures are tied to the HVAC system.
Heat exchanger cracks can pose a safety concern and should be addressed right away.

Decatur’s humid subtropical climate means your cooling system works hard from spring through early fall, and your heating system takes over during our unpredictable winters. That kind of year-round demand puts real stress on HVAC equipment, and emergency failures are often the result of systems that have been working overtime.

Steps to Take Before Our Technician Arrives

While you wait for our team to arrive, there are a few simple things you can do to stay safe and help speed up the repair process.

heck your thermostat settings and make sure it's set to the right mode and temperature.
Replace or check your air filter if you haven't done so recently, since a clogged filter can trigger shutdowns.
Check your circuit breaker to see if a breaker has tripped and needs resetting.
If you smell gas, leave the home immediately and call your gas provider before calling us.
Clear the area around your indoor and outdoor units so our technician has easy access.

These steps won’t always fix the problem, but they can help rule out simple causes and make the repair visit faster.
