When Georgia Heat Won’t Let Up, Make Sure Your AC Can Keep Up
7 Signs It’s Time to Replace Your Air Conditioner in Peachtree City, GA
At John’s Heating, Cooling, and Appliance Repair — proudly serving Peachtree City, Fayetteville, and all of South Metro Atlanta — we’ve helped hundreds of families decide when to repair or replace their air conditioning systems. Below, we’ll cover the top signs your AC may be nearing the end of its life and what to do before the next heat wave hits.
1. Frequent Breakdowns and Costly Repairs
If your AC seems to need service every summer, it’s likely approaching the end of its lifespan. Small repairs can quickly add up — and when you factor in service calls, refrigerant refills, and parts, replacement often becomes the more affordable long-term choice.
A good rule of thumb: if your next repair will cost 30% or more of a new system, it’s time to consider replacement. You can always schedule a diagnostic with our technicians for an honest assessment.

2. Age of the System
The average air conditioner lasts 10–15 years, but Georgia’s hot summers put extra strain on your system. If yours is more than a decade old, you’re likely spending more on energy than necessary. Modern units with SEER2 ratings are designed for higher efficiency and quieter operation. If your system still uses R-22 (Freon), replacement is especially important, since that refrigerant is no longer produced or environmentally approved.

3. Rising Energy Bills
Has your electric bill spiked lately, even though your usage hasn’t changed? Older units can lose efficiency every year, forcing them to work harder for the same comfort level. In Georgia, the average residential bill runs around $226/month, and an aging AC can add $40–$70 to that total. Upgrading to a high-efficiency system can often cut those costs by up to 30–40%.

4. Uneven Cooling or Poor Airflow
If certain rooms are too hot while others feel cold, you may have airflow or duct issues, or your compressor could be failing. Older blowers and fans lose power over time, leading to inconsistent comfort levels throughout your home.
Our technicians can inspect duct leaks and test your blower motor to determine whether a tune-up or full system replacement is needed.

5. Unusual Noises or Odors
Grinding, squealing, rattling, or buzzing are all red flags. These sounds can point to failing motors, damaged bearings, or electrical problems. If you notice musty smells, that could mean mold inside your ducts, while burning or metallic odors often point to electrical overheating. Don’t wait for a full failure — small issues can quickly turn into major repairs if ignored.

6. Moisture, Leaks, or Refrigerant Problems
Excessive moisture around the indoor or outdoor unit can cause mold growth and water damage. If you notice a hissing sound or oily residue, you may have a refrigerant leak, which reduces cooling power and poses environmental hazards. If your system still uses R-410A refrigerant, consider replacing it with a next-generation model that uses R-454B or R-32 — both are more efficient and eco-friendly.

7. You’re Planning to Sell or Remodel
If you’re remodeling or preparing to list your Peachtree City home, a new HVAC system is one of the smartest upgrades you can make. Buyers value energy efficiency and reliability, and a newer system often boosts home resale value while reducing inspection concerns.
Why Immediate Attention Matters
Delaying AC replacement can cause higher repair costs, refrigerant leaks, or total system failure at the worst possible time. A proactive approach saves money, improves comfort, and ensures your system runs safely all summer.
5 Questions Homeowners Ask About AC Replacement
1. Should I repair or replace my air conditioner?
If your AC is more than 10 years old and repairs exceed 30% of the cost of a new system, replacement makes more sense. Our team can help you evaluate both options.

Yes. Newer high-efficiency systems can cut energy usage by 30–40%, especially if you’ve been running an older 10-SEER model.
4. What size system do I need for my home?
Sizing depends on square footage, insulation, and layout. Our technicians use Manual J load calculations to design the right system for your property.

❄️ Does Freon Wear Out? The Complete Guide to AC Refrigerant Myths & Leaks For more than 28 years, John’s Heating, Cooling, and Appliance Repair has been the trusted choice for homeowners and businesses across Fayetteville, Peachtree City , Newnan , Griffin , Sharpsburg , Senoia , Tyrone , Zebulon , and South Metro Atlanta . One of the most common questions we hear is: 👉 “Does Freon wear out in my air conditioner like motor oil in a car?” The short answer: No. Refrigerant doesn’t wear out — it leaks. In this guide, we’ll bust the myths, explain the science, and show you why leaks are the real problem — plus how our team fixes them the right way. 🔍 Part 1: Why People Think Freon “Wears Out” When an air conditioner stops cooling, it’s easy to assume the refrigerant (often called Freon) just “ran out.” The logic makes sense — cars need oil changes and fluid top-offs. But refrigerant doesn’t work that way. How Refrigerant Really Works Closed-Loop System – Refrigerant runs in a sealed cycle, absorbing and releasing heat. It isn’t consumed. No Combustion – Unlike fuel or oil, refrigerant doesn’t burn or break down. Constant Cycle – The same refrigerant circulates through compression and expansion, year after year. 👉 If your AC is low on refrigerant, it’s not because it wore out — it’s because it escaped through a leak. ❄️ Part 2: Why Leaks, Not Wear, Cause Problems Refrigerant leaks are the real issue. Once refrigerant escapes, your AC loses efficiency and struggles to keep up with the summer heat in Georgia. Common Signs of a Refrigerant Leak Warm air blowing from vents Ice buildup on coils or refrigerant lines Hissing or bubbling noises near the unit Higher electric bills despite poor cooling The Cost of Ignoring a Leak Burned-out compressor – one of the most expensive AC repairs Energy bills up 30–50% – wasted money every month Poor indoor air quality – sticky, uncomfortable air System breakdowns – failure right when you need it most 👉 Just “topping off” Freon doesn’t solve the problem. It’s a temporary band-aid that guarantees you’ll be calling again. 🔬 Part 3: The Science of Refrigerant Refrigerant is designed to last the entire lifespan of your AC system. It circulates through indoor and outdoor coils, absorbing and releasing heat. It doesn’t get used up or burned. It simply changes state — liquid to gas and back again. If levels are low, the system is leaking. Period. 👉 Learn more about our Air Conditioning Repair in Peachtree City page. ❄️ Part 4: Why Honest Repairs Beat “Top-Offs” Unfortunately, some HVAC companies keep homeowners stuck in the Freon myth. They’ll top off refrigerant year after year without fixing the actual leak. The Wrong Way: Refrigerant Top-Offs Quick cooling, but only temporary Repeated service calls = higher costs Worsening leaks that damage your compressor The Right Way: Leak Detection & Permanent Repair At John’s Heating, Cooling, and Appliance Repair, we: Use advanced tools to locate leaks. Repair the source of the problem.

No. If refrigerant levels are low, it means there’s a leak. How long does refrigerant last? The entire life of your system — unless it escapes. Can I add more refrigerant? Not without sealing the leak. Otherwise, it will just leak out again. What happens if I ignore a leak? Expect higher bills, poor cooling, and eventual compressor failure. ✅ Final Takeaway Refrigerant doesn’t wear out. If your AC is low, it’s leaking — and leaks require professional repair. At John’s Heating, Cooling, and Appliance Repair, we offer honest, long-lasting solutions that keep your system running efficiently and your family comfortable. 📞 Call (678) 603-7775 today — and put an end to the Freon myth once and for all.
