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.

Benefits of Annual Furnace Maintenance

A little preventive care goes a long way for your furnace. Skipping maintenance might not seem like a big deal until something breaks down on the coldest night of the year. Here’s what you get when you stay on top of it.

Scheduling a tune-up before heating season helps your furnace start up without any surprises, which matters when Decatur temperatures drop suddenly, and you need reliable heat fast.
A well-maintained furnace runs more efficiently, which means it uses less energy to heat your home and keeps your monthly utility bills lower.
Catching small problems early, like a worn belt or a dirty burner, prevents them from turning into expensive repairs down the road.
Regular maintenance extends the overall life of your system, helping you get the most out of your investment before a replacement becomes necessary.
A clean, properly functioning furnace also means better indoor air quality, which is especially important for households with allergy sufferers or respiratory sensitivities.

Dangers of Avoiding Regular Maintenance

Putting off furnace maintenance isn’t just a comfort risk. It can also be a safety risk. Here’s what can happen when regular service gets skipped year after year.

A cracked heat exchanger is one of the most serious issues that can develop in a neglected furnace, and it can allow carbon monoxide to leak into your living space without any visible warning signs.
Dirty or clogged components force your furnace to work harder than it should, putting unnecessary strain on the system and potentially leading to premature failure.
Buildup in the burners or ignition system can cause your furnace to short-cycle, meaning it turns on and off repeatedly without fully heating your home.
Neglected systems are more likely to fail without warning, leaving your family without heat during the coldest stretches of a Georgia winter.
Skipping maintenance can also void the manufacturer’s warranty on newer systems, leaving you without coverage when you need it most.

Our Furnace Maintenance Checklist

When one of our technicians comes out for a maintenance visit, they work through a thorough inspection of your entire heating system. Every visit includes a review of the following.

Inspecting and cleaning the heat exchanger for cracks or buildup that could affect safety or performance.
Checking and replacing the air filter if needed to protect airflow and indoor air quality throughout your Decatur home.
Testing the ignition system and burners to make sure your furnace lights reliably and burns cleanly.
Lubricating all moving parts to reduce friction and wear on motors and fans.
Inspecting the flue and venting system to confirm exhaust gases are being safely directed out of the home.
Testing the thermostat for accuracy and calibration to ensure your system heats to the temperature you set.
Checking electrical connections and controls to identify any wiring issues before they cause a breakdown.
Measuring system performance to confirm your furnace is operating within the manufacturer’s specifications.

Common Issues We Find in Maintenance Visits

After decades of servicing furnaces across the Atlanta area, our technicians have seen the same problems come up time and again. Here are some of the most common issues we catch during routine visits before they become bigger headaches.

Dirty or clogged filters are the most common finding and one of the easiest to fix. A restricted filter forces the blower to work harder and can cause the system to overheat.
Ignition problems are especially common in systems that sit unused through the warmer months. Pilot lights and electronic ignitors can wear out or get dirty over time.
Worn blower belts and motor bearings are common in older systems and can lead to loud operation or a complete loss of airflow if left unaddressed.
Blocked or deteriorating flue pipes are a concern we take seriously, since proper venting is essential to keeping combustion gases out of the living space.
Thermostat calibration issues are easy to overlook but can cause your system to run longer than necessary or shut off before your home reaches the right temperature.

Frequently Asked Questions

How often should I schedule furnace maintenance in Decatur, GA?

Once a year is the standard recommendation, and the best time to schedule it is in the fall, before you start running your heat regularly. Getting ahead of the season means you’re not scrambling if something needs to be repaired.

Does Decatur's climate affect how often my furnace needs service?

The Atlanta area is known for high humidity, even in winter. Moisture can seep into your system over time, contributing to corrosion or microbial growth inside the unit. Annual maintenance helps catch those issues before they become serious.

What happens if I skip furnace maintenance for a few years?

Skipping maintenance increases the risk of breakdowns, reduces efficiency, and can shorten your system’s lifespan. In more serious cases, neglected furnaces can develop safety issues like cracked heat exchangers that put your household at risk.

How long does a furnace maintenance visit take?

Most visits take between one and two hours, depending on the age and condition of your system. If our technician finds something that needs attention, they’ll walk you through what they found and what your options are before doing any additional work.

Does Ace & A Heating and AC service all furnace brands?

Yes. Our technicians are trained to service all major HVAC brands and receive factory training on an annual basis, so they stay current with newer systems as well as older models.
