It Worth Fixing a 20-Year-Old AC Unit? Here’s What You Need to Know

Air conditioners are vital for keeping your home cool, safe, and comfortable—especially in Georgia’s heat. But like all appliances, they have a lifespan. If your system is 20 years old or more, it may be time to stop repairing and start replacing.

At Central Heating and Air Conditioning, we help homeowners make smart, informed decisions about their HVAC systems. If your AC is aging, here’s what you need to know—and why replacement may be the better option.

Why Replacing a 20-Year-Old Unit Makes Sense

Trying to extend the life of an outdated AC unit can actually cost you more in the long run. Here’s why:

Higher Repair Costs

Older units tend to break down more often. Multiple repairs over a short period can easily exceed the cost of a brand-new, energy-efficient system.

Outdated Refrigerant

If your system still uses R-22 refrigerant, you’re dealing with a phased-out product that’s no longer manufactured. That means it’s expensive, hard to find, and a signal that your system is well past its prime.

Rising Energy Bills

Today’s AC units are far more efficient. If your monthly utility bill keeps climbing, your outdated system could be the culprit. Newer models use significantly less energy to cool your home.

Reliability Issues

Frequent breakdowns, strange noises, uneven cooling, and poor indoor air quality are all signs your system is struggling to keep up.

Common Signs It’s Time to Replace, Not Repair

If you’re experiencing any of the following, a replacement is likely the smarter investment:

• Your unit is 15+ years old
• Rising energy bills without changing usage
• Certain rooms are hotter than others
• You’re calling for repairs more than once a year
• Loud or unusual noises during operation
• Musty or burnt odors
• The unit cycles on and off frequently
• It can’t keep up with humidity or air quality control

If this sounds familiar, call Central Heating and Air Conditioning at 404-261-2280 for a system evaluation. We’ll help you decide what makes the most financial and practical sense for your home.
