Out with the old, in with the new.
How do I know my HVAC unit is at the end of its life?

Age of the Unit

The average lifespan of an HVAC unit is 15 years. Units that are 10-years and older can start to wear out. If you have an older system, it’s probably more cost-effective to replace it than to continue to make repairs. Bonus: a newer HVAC system will definitely be more energy efficient!

Noises: Knocks, Clanks, and Rattles

If your HVAC system is making sounds you’ve never heard before, then it’s time to give us a call. Strange, persistent sounds usually indicate a problem that is best addressed sooner rather than later.

Foul Odors

When a burning smell is a cause for serious concern:

  • It smells like electrical wires are burning
  • It smells like burning rubber
  • There is a persistent musty/mildew smell
  • Your heater smells smoky or oily


The EPA recommends that homes keep a humidity level between 30-50%. When levels exceed 60%, they can lead to mold and mildew growth, dust mites, asthma, allergies, and more. If your HVAC system is older or the wrong size for your home, it may be inefficient in removing water from the air. This means that your system will have to work longer and harder to cool or heat your home, adding wear to the unit, and it may never deliver the result that you want: a comfortable home.

Weak Airflow, Blowing Hot Air, or Leaks

If the air coming out of your vents isn’t the right temperature or isn’t blowing forcefully enough, then this is a sign something’s not right with your system. Cracked ducts or leaking freon could be the culprit. Regardless, it’s best to give us a call to assess the problem.

Your HVAC System Uses R22 Freon

R22 Freon is being phased out and has become very costly to replace. It’s more cost-effective in the long run to buy a new unit rather than keeping the old one limping along.

High Energy Bills

Need we say more? Higher energy bills are never good news!

Recurring Repairs

Although we love seeing our customers, we really shouldn’t be seeing you too often. If you have to schedule multiple repairs with us, it’s probably time to invest in a new HVAC system.

If your AC unit is experiencing any of these symptoms, please call a Stuart Pro Comfort Specialist. 770.813.1316

How to Choose a New HVAC System 

Installing or replacing central air is a big commitment and investment in your home, and all the choices available can be overwhelming. We’ve put together a buying guide to help you make the most informed decision you can.

System Size

35–50% of your annual energy bill accounts for heating your home. Another 50% of annual energy bills are due to cooling your home. Your energy savings and unit performance will suffer if you buy a system that’s both too small or too large for your home. Our Comfort Specialists are trained to know exactly what unit will fit best for your home and our local Georgia climate.

Efficiency Ratings

An efficient system will pay you back in energy consumption. HVAC units use a rating system known as “SEER Ratings” (Seasonal Energy Efficiency Ratio), which ranges from a SEER rating of 7.7 to 18+. Although many other factors weigh into choosing the right SEER rating for your home, the higher the SEER rating, the more energy-efficient the unit is. You should purchase a unit with a SEER rating of 15 or greater.

Local Climate

Hot and humid Summers, Cold and Rainy Winters, what’s the best HVAC Unit choice for our Georgia climate? See our list of recommended HVAC units below.

Chelle J. | Stuart Pro Customer

I’m genuinely pleased with the service technician that comes out for the annual maintenance procedure. This time, I wasn’t disappointed either. I will continue to recommend this company for service. Thanks!

Mark F. | Stuart Pro Customer

My Technician (Luis) did a great job. He listened and understood the problem and then diagnosed the cause of the problem. He clearly explained the issue and the options for repair, he had the parts on his truck and performed the repair work without the need for a second visit. I would recommend Stuart Pro to my friends and family.

Jenny V. | Stuart Pro Customer

Samir was extremely courteous and knowledgeable. He took his time and explained what he was doing and made sure I understood. He was very clean and made me feel comfortable to have him in our home especially during this pandemic.

Charlie M. | Stuart Pro Customer

They have always gone above and beyond. Truly a great company to do business with. Highly recommend using any of their services. You won’t have to worry about any horror stories when dealing with this company Eugene was extremely polite and efficient. And Alex is an excellent service tech as well. I’m sure the other employees are fantastic but have only have had the pleasure of dealing with these two. Always super responsive and care about customer service and experience.

Astrid C. | Stuart Pro Customer

I absolutely loved our experience with Stuart Pro. From the beginning, our salesperson Shayne, was very detailed in examining our house to make sure we had the proper equipment. When the team arrived, they were quick to get started and got the job done quick. The installation team, Fernando and Eli, were such a great team. They made sure they went over what we needed to have done and were quick to install extra vents in our home. I would highly recommend this team to anyone and everyone. I am very satisfied with our experience. After 3 years without working AC, I am glad we went with Stuart Pro.

Gary H. | Stuart Pro Customer

Service technicians were on-time, courteous and efficient in diagnosing and correcting the HVAC problem. Post-repair followup was excellent. Will do business again.

Rick & Pattie G. | Stuart Pro Customer

Very well run organization, they all worked as a team from the very start of my appointment/needs.

Larry B. | Stuart Pro Customer

Stuart Heating & Air recently installed a new air conditioner on our houseboat. Nathan came to the boat and spent a good deal of time assessing what we had and what was needed. Jeff, Mark and all the installers did a great job and left the boat in perfect condition when they left.
