Do you need a new AC unit?
You’ll want to change out your old AC unit as soon as it stops working.
It’s time for an AC replacement project if...
- Your unit still runs on old, harmful refrigerant
- Your utility bill keeps rising with no sign of slowing down
- Your unit runs constantly without making an impact on your home
Additionally, the age of your unit can dictate when to replace it. Most AC units only last around 15 years, so it’s time to consider an upgrade if your unit is older.
