Your air conditioner has kept you comfortable through countless Florida summers, but lately, it might not be keeping up. Maybe it’s running longer than usual, making new noises, or your electric bill has increased. At some point, every homeowner faces the same question:
Here’s how to tell, from the experts at Donovan Air, Electric & Plumbing, who’ve been keeping Northeast Florida comfortable since 1987.
In Northeast Florida, most homes use heat pump systems, though homeowners often just call them their AC or heater depending on the season. It’s the same system doing double duty all year long. Because it runs nearly nonstop, cooling through long summers and heating during cold snaps, its lifespan can be shorter than systems up north that get seasonal breaks.
Florida rule of thumb: Once your AC is over 10 years old and needs a costly repair (like a compressor, coil, or motor), replacement often saves you more long-term than another band-aid solution.
Before spending money on yet another repair, think long-term. Older systems often use outdated components, run less efficiently, and can be more expensive to keep alive.
Here’s a quick repair vs. replace guide:
(like a capacitor or contactor)
Better Option: Repair
Why? Quick, affordable fix
(compressor, coil, motor)
Better Option: Replace
Why? Costly repair with more failures likely ahead
(especially if using R-22 or R-410A)
Better Option: Replace
Why? Costly repair with more failures likely ahead
Better Option: Replace
Why? You’ll pay full price for all future repairs
Pro Tip: If you’ve repaired your system more than three times in two years, replacement will almost always save you money and frustration.
If your electric bill keeps climbing even though your thermostat settings haven’t changed, your AC is likely losing efficiency. Aging systems can lose up to 30% of their cooling capacity over time, especially with dirty coils, weak refrigerant, or airflow issues.
Upgrading to a modern system pays off fast:
Replacing a 10-SEER unit with a 16-SEER2 model can save the average homeowner $300–$600 per year on electricity alone. New systems are also quieter, better at controlling humidity, and can often pay for themselves through reduced energy costs and fewer service calls.
If you’re noticing:
Your AC may be struggling to keep up. These symptoms often point to compressor strain, duct leaks, or worn parts; all signs it’s time to evaluate replacement.
A well-maintained system can last years longer than a neglected one. If you’re part of our Donovan360 Membership, you’ve already had your system cleaned, drained, and tuned twice a year, meaning it’s likely still performing strong.
However, if it’s been years since your last tune-up and your system is showing signs of decline, replacement is likely the safer investment.
Replacing your system isn’t just about new equipment; it’s also a chance to save. Donovan helps homeowners qualify for federal energy tax credits and manufacturer rebates on high-efficiency systems. Plus, we include a free 10-year parts and labor warranty kit on select models, so you won’t have to worry about costly repairs anytime soon.
When you’re unsure, it helps to have a technician who will show you what’s wrong, not just tell you. Our comfort specialists take photos, explain your options clearly, and walk you through transparent repair-versus-replace comparisons. You’ll always know what makes the most sense for your home and budget.
Bottom Line
If your AC is:
…it’s time to start planning for a replacement.
If it’s newer, properly maintained, and the repair is minor, then fixing still makes sense. Either way, Donovan will give you an honest, pressure-free evaluation so you can make the right call with confidence.
