Questions & Answers
Frequently Asked Questions
What are the most common HVAC problems in Charleston?
Our heat and humidity put heavy demand on systems, so we often see refrigerant leaks, frozen coils, clogged drain lines, failed capacitors, and airflow problems from dirty filters. Coastal salt air can also wear on outdoor units over time.
How do I know if I should repair or replace my HVAC system?
Look at the age of your system, how often it breaks down, and how the repair cost compares to its value. If your system is older and repairs are piling up, replacement may be the smarter long-term choice. We will give you an honest recommendation.
What should I do with my HVAC system during hurricane season?
Before a storm, secure loose items around your outdoor unit and consider turning off power to the system if flooding or power surges are likely. After the storm, check for debris or water damage before turning it back on. If anything looks off, call us for an inspection.
What affects the cost of an HVAC repair?
Cost depends on the part involved, the type and age of your system, how hard the part is to reach, and labor time. We diagnose first and give you upfront pricing before any work begins.
