When to Consider AC Replacement in Charleston
Air conditioners don’t last forever, especially in Charleston where systems work overtime to combat heat and humidity. Recognizing when it’s time to replace your AC helps avoid sudden breakdowns and costly repairs.
Age of the System
Most units last 10–15 years. If yours is approaching this range, replacement often makes more financial sense than repeated repairs.
Frequent Repairs
If your AC requires constant service calls or major component replacements, upgrading may be the more cost-effective choice.
Rising Energy Bills
Older systems tend to lose efficiency, leading to higher monthly utility costs. New installations are designed with modern energy-saving technology.
Inconsistent Cooling
Uneven temperatures, poor airflow, or frequent cycling signal a system that may no longer meet your home’s needs.
