7 Signs It's Time to Replace Your AC
Not sure if you should repair or replace? Here are the clearest signs your AC is ready for retirement:
- Your AC is over 10-12 years old — Modern systems are 30-50% more efficient than units from a decade ago
- Repair costs are climbing — If a single repair costs more than 50% of a new system, replacement is smarter
- Your energy bills keep rising — Old, inefficient AC units work harder and cost more to run
- Uneven cooling between rooms — A failing AC struggles to maintain consistent temperatures
- Frequent breakdowns — More than 2-3 service calls per year means the system is on its last legs
- Uses R-22 refrigerant — R-22 is obsolete and refilling it is now extremely expensive
- Constant humidity problems — Aging systems lose their ability to dehumidify properly
If you checked two or more boxes, replacement will likely save you money in the long run.

AC Brands We Install
We're a Bryant/Carrier Factory Authorized Dealer, but we install and service all major brands:
- Bryant — Our top recommendation: rock-solid reliability, excellent warranties
- Carrier — Industry leader in efficiency and innovation
- Lennox — Premium efficiency options
- Trane, Rheem, Goodman, Amana, York, Daikin — Available on request
Our advice: Don't choose by brand alone. The quality of the installation matters more than the brand on the box. A poorly-installed premium unit will fail faster than a properly-installed mid-range unit.
Energy Efficiency: Save Money Long-Term
A new high-efficiency AC system can cut your cooling bills by 30-50% compared to an old 10-SEER unit. Here's what to know:
- SEER2 14.3 — Current minimum efficiency for the Southeast (federal requirement)
- SEER2 15-17 — Mid-range, great value for most homes
- SEER2 18-20+ — Premium efficiency, ideal for larger homes or warmer climates
- Variable-speed systems — Maximum comfort and efficiency, especially good for humidity control

Frequently Asked Questions — AC Replacement
How long does an AC replacement take? Most complete AC replacements are completed in one full day (6-8 hours). Larger systems or projects requiring ductwork modifications may take 2 days.
How long do new AC systems last? With proper installation and annual maintenance, a quality AC system should last 15-20 years. Most manufacturer warranties cover 10 years on parts.
Should I replace just the outdoor unit or the whole system? We almost always recommend replacing both the outdoor condenser and the indoor coil/air handler together. Mismatched systems lose efficiency, void warranties, and often fail prematurely.
Do you offer financing? Yes — 0% interest financing is available on qualifying systems. We can get you approved in minutes. Monthly payments often start around $99/month.
Do I qualify for federal tax credits? The Inflation Reduction Act offers up to $2,000 in tax credits for qualifying high-efficiency heat pumps and AC systems. We'll help you understand what you qualify for during your free estimate.
What size AC system do I need? This depends on your home's square footage, insulation, windows, sun exposure, and ductwork. We perform a Manual J load calculation during every estimate — no guesswork.
Can I replace my AC in the winter? Absolutely. Replacing in the off-season often means better availability and competitive pricing. Don't wait until summer when everyone needs service.
What brand do you recommend? We're a Bryant/Carrier Factory Authorized Dealer because we believe in their reliability and warranty support. But we'll honestly recommend the best system for your home and budget — not what makes us the most money.
Will my energy bill really go down? Yes — replacing a 10-15 year old system with a modern high-efficiency unit typically reduces cooling costs by 30-50%. The savings often pay for the upgrade over the system's lifetime.
