Signs & Costs, Demystified

Signs It's Time to Replace
If you're seeing several of these, replacement usually beats another repair:
- 10–15+ years old — past the typical lifespan of an AC or heat pump
- Frequent, costly repairs — especially a compressor, coil, or heat exchanger
- Rising energy bills — an aging system works harder for less comfort
- Uneven temps, noise or humidity — comfort and air quality are slipping
- Old R-22 refrigerant — phased out and expensive to top off

Replacement Questions, Answered
How do I know if I need to replace my HVAC system?
Common signs include a system over about 10–15 years old, frequent or expensive repairs, rising energy bills, uneven temperatures, excess noise or humidity, or a unit still on phased-out R-22 refrigerant. We'll inspect your system and give you an honest repair-or-replace recommendation.
Should I repair or replace my AC unit?
If your AC is under about 10 years old and the repair is minor, repair usually makes sense. If it's older, needs a major repair like a compressor or coil, or the repair cost approaches half the price of a new unit, replacement is often the smarter long-term investment. We give you the numbers so you can decide.
How much does HVAC replacement cost?
A new system replacement typically runs about $3,000–$7,500 for AC or furnace, and roughly $7,000–$13,000 for a full AC-and-furnace replacement, depending on type, size, efficiency, and ductwork. We give a clear estimate up front, our free Instant Quote prices a system online, and flexible financing is available.
How long does an AC or HVAC system last?
In Georgia's climate, most air conditioners and heat pumps last about 10–15 years and furnaces about 15–20 years with regular maintenance. Once a system passes that range, repairs add up and efficiency drops, so a replacement often pays for itself in lower bills and fewer breakdowns.
Can I replace just the AC and not the furnace?
Sometimes — but it's not always the best value. Because the indoor and outdoor units are matched for efficiency, replacing only half of an aging system can lower performance and void some warranties. We'll tell you honestly whether a single-component or full-system replacement makes the most sense.
Do you offer financing for a replacement system?
Yes. We offer flexible financing and payment plans so you can replace your system without straining your budget. Ask us about current options and manufacturer rebates on a new high-efficiency system.
How long does an HVAC replacement take?
Most residential replacements take about one to two days, depending on the system type, your home's size, and whether ductwork or electrical work is needed. A straightforward AC or furnace swap is often done in a single day. We'll give you a clear timeline up front.
What brands do you install when replacing a system?
All major brands — Lennox, Trane, Carrier, Daikin, American Standard, Bryant, Goodman, and Amana. As a Lennox Premier Dealer, we'll help you choose the right, efficient replacement system for your home and budget.
