Questions & Answers

Frequently Asked Questions

Why is my AC running but not cooling?

Common causes include a dirty air filter, a refrigerant leak, a frozen evaporator coil, or a failing capacitor or compressor. Start by checking your filter and thermostat settings. If the air is still warm, shut the system off and call us so a small problem does not become a bigger one.

Is it worth repairing an older air conditioner?

Often it is, especially for a minor repair on a system in good overall shape. If your unit is older, needs repairs often, or uses an outdated refrigerant, replacement may save you more over time. We will give you an honest assessment and let you decide.

How quickly can you come out for AC repair?

Most appointments are scheduled within 24 to 48 hours. For emergencies, we offer same-day service whenever possible. Call (843) 969-2269 and we will get you on the schedule.

What affects the cost of an AC repair?

Cost depends on the part that failed, how accessible it is, the age and type of your system, and how much labor the fix requires. Our technicians diagnose the problem first and give you upfront pricing before any work begins.
