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.

Signs You Need to Replace Your Furnace

Sometimes a repair is all you need, but other times replacement is the smarter move. Here are some signs it may be time for a new furnace.

Your furnace is over 15 to 20 years old and requires frequent repairs that are adding up in cost.
Your energy bills have gone up noticeably, even though your usage hasn’t changed.
Some rooms in your home heat unevenly or never seem to get warm enough.
Your furnace makes unusual noises like banging, rattling, or squealing during operation.
Your system cycles on and off more frequently than it used to.
You’ve noticed more dust, dry air, or worsening indoor air quality since your system started aging.

If any of these sound familiar, it is worth having one of our technicians take a look. Our team can evaluate your system and determine whether repair or furnace installation & replacement in Decatur, GA would be the better solution. We will give you an honest assessment and help you decide what makes the most sense for your home, comfort, and budget.

How Long Do Furnaces Typically Last

Most furnaces are built to last between 15 and 20 years with regular maintenance. Some systems can push past that range, while others may start showing signs of wear earlier, depending on how well they’ve been maintained and how hard they’ve had to work.

In Decatur, GA, furnaces don’t face the same brutal winters you’d find further north, but that doesn’t mean they’re off the hook. Georgia’s humidity can take a toll on HVAC components over time, and a system that runs through humid summers and cooler winters is still working year-round. Keeping up with annual tune-ups goes a long way toward getting the most out of your equipment.

When your system starts needing repairs more often or your technician is finding the same issues coming back, that’s usually a sign the furnace is nearing the end of its useful life.

Furnace Options to Choose From

There’s no one-size-fits-all furnace, and the right system for your home depends on your setup, your budget, and how you heat your space. We’ll walk you through your options and help you find the right fit.

Gas Furnaces are the most common choice for homes in the Atlanta area. They heat quickly and efficiently, and modern units come with high AFUE ratings that can significantly reduce your energy costs compared to older systems.

Electric Furnaces are a good option for homes without a gas line. They tend to have lower upfront costs and require less maintenance, though operating costs can be higher depending on your electricity rates.

Heat Pumps are worth considering if you’re looking for a system that handles both heating and cooling. In Georgia’s climate, where winters are relatively mild, heat pumps are a practical and energy-efficient option for many homeowners.

Our team will help you compare your options based on your home’s size, your existing ductwork, and what makes the most sense long-term.

Frequently Asked Questions

How do I know if I should repair or replace my furnace?

A good rule of thumb is to multiply the repair cost by the age of your system. If that number exceeds the cost of a new furnace, replacement is usually the better investment. Our technicians can help you work through that decision honestly.

How long does a furnace installation take?

Most furnace installations are completed in a single day, typically within four to six hours, depending on the complexity of the job and whether any additional ductwork adjustments are needed.

What size furnace does my home need?

Furnace sizing depends on your home’s square footage, insulation, ceiling height, and other factors. An undersized or oversized unit can lead to comfort issues and higher energy bills. We assess your home before recommending a system to make sure you get the right fit.

Does the humidity in Decatur, GA, affect my furnace?

Georgia’s humidity primarily impacts cooling systems, but it can affect your furnace over time as well. Moisture can contribute to wear on components, corrosion, and air quality issues. Keeping up with regular maintenance helps protect your system in our climate.

Do you offer financing for furnace replacement?

Yes. We understand that a new furnace is a significant expense, and we offer financing options to help make it more manageable. Ask us about current options when you call for your estimate.
