Repair or Replace? How to Decide When Your HVAC System Acts Up in Dawsonville, GA

 
 

1. System Age

If your system is:

  • Under 10 years old – it’s often worth repairing.

  • 10–15+ years old – you should consider replacement, especially if repair costs are rising.

New systems are more energy-efficient, and manufacturers like Trane and Daikin offer excellent warranties.

2. Frequency of Repairs

Needing minor service once a year is normal—but if you’re calling for repairs every few months, it adds up fast.

💡 Rule of thumb: If repair costs exceed 50% of the price of a new system, replacement is typically more cost-effective.

3. Energy Bills Are Rising

An aging or malfunctioning HVAC system has to work harder to keep your home comfortable, which means higher power bills.

Replacing your system can result in:

  • Lower monthly energy costs

  • Better temperature control

  • Improved indoor air quality

4. Comfort Problems

Uneven temperatures, high humidity, or constant cycling are signs your system isn’t keeping up with your home’s needs—especially in Georgia’s hot summers or chilly winters.
