Should you repair or replace your HVAC system?
Use clear guidelines on equipment age, repair costs, and energy savings to make an informed choice for your Cobb County home.
Repairing is likely your best option
Your score of $4,500 is below $5,000. Repairing your existing equipment remains cost-effective for your Marietta home.
Age under 10 years
Systems under a decade old usually have substantial operational life remaining.
Repair cost under $500
Minor component failures like capacitors or igniters are fast, affordable fixes.
Consistent comfort levels
If temperatures and humidity remain steady, the core system remains healthy.
Active warranty coverage
Manufacturer parts warranties frequently cover replacement components.
Age over 12-15 years
Heat pumps and air conditioners lose efficiency and reliability as they pass 12 years.
Costly component failure
Compressor or heat exchanger failures often cost more than half a new unit.
Uses phased-out R-22 refrigerant
R-22 supplies are restricted and expensive, making refrigerant leaks costly.
Spiking monthly energy bills
Degraded SEER performance forces systems to run longer to maintain set temperatures.

How age impacts your decision
In Cobb County's climate, cooling systems run thousands of hours each summer. Standard air conditioners and heat pumps last roughly 10 to 15 years with routine maintenance. If your unit is under 10 years old, repair is almost always the right choice. Past 12 years, major repairs yield diminishing returns.
