Q&A

How often should I change my air filter in Charleston to prevent clogs?

In Charleston's humid, pollen-heavy environment, we recommend checking your air filter monthly and replacing it every 1-3 months, depending on usage and filter type. Clogged filters reduce airflow, strain your system, and can lead to higher energy bills or breakdowns. Our technicians can assess your specific needs during a maintenance visit.

What are the signs of an AC capacitor failure in my Charleston home?

Common signs include your AC unit humming but not starting, frequent tripping of circuit breakers, or warm air blowing from vents. Capacitor failures are frequent here due to heat and humidity stressing systems. If you notice these issues, contact us promptly for a diagnostic to prevent further damage and restore cooling quickly.

Can regular maintenance help prevent common HVAC problems in Charleston?

Yes! Our preventative maintenance services include cleaning coils, checking capacitors, and replacing filters to address Charleston-specific issues like clogging and electrical wear. This helps improve efficiency, extend system life, and reduce the risk of sudden breakdowns during hot summers. We recommend scheduling maintenance at least twice a year.
