Charleston’s summer heat is no joke—and neither is a broken AC unit. Property managers overseeing single-family homes in Summerville, Goose Creek, and Ladson know how quickly HVAC complaints can pile up in hot weather. The key to avoiding emergency calls? Routine, preventive AC maintenance.

Start with filter changes. In high-use months, filters should be changed every 30 days. Clogged filters restrict airflow and reduce efficiency, often leading to higher energy bills and early system failure.

Next, check your thermostat. Smart thermostats not only reduce energy usage, they also help you spot temperature inconsistencies that could signal larger HVAC issues. If tenants complain about uneven cooling, it’s time for a duct inspection.

Outdoor units should be kept clear of debris. Trim bushes and remove leaves from around the condenser to ensure proper airflow. Inside, schedule a coil cleaning and blower inspection every spring.

For rental homes in humid areas like Ladson, condensate drain lines are another problem point. When they clog, water backs up into the home. Include drain line flushing as part of annual service.

Pro Tip: Bundle AC tune-ups with dryer vent cleaning and air duct inspections to reduce service costs.

Property managers who schedule HVAC inspections in May can reduce emergency calls in July. It’s an investment that pays off in fewer complaints, lower bills, and better tenant satisfaction.
