When Is It Time to Replace Your AC?
Not sure if it’s time to replace your unit? Here are a few signs your AC is past the point of repair:
- It’s more than 10–15 years old
- Frequent, expensive repairs are adding up
- Your energy bills keep climbing
- The system runs constantly but doesn’t cool
- It uses R-22 refrigerant (which is no longer supported)
We’ll help you weigh your options honestly. Sometimes, it’s more cost-effective to replace rather than continue sinking money into repairs. And our team always lets you know the cost before doing anything, so there are no surprises.
