Carolina summers don't ease in — they arrive. A little spring prep now keeps your AC ready before the first 90-degree day.
Replace or check your air filter
Start here. A clean filter is the cheapest way to protect efficiency and airflow. Swap a 1-inch filter and check thicker media filters.
Clear around the outdoor unit
Trim back plants and clear leaves and debris within about two feet of the condenser so it can breathe. Gently rinse the fins if they look dirty.
Test your thermostat
Switch to COOL and make sure it responds. Fresh batteries and a quick schedule check now save a mid-summer headache — see our thermostat settings guide.
Check the condensate drain
A clogged drain line causes water leaks and can shut the system down on a hot day. Make sure it’s clear.
Listen and feel
Run the system briefly. Weak airflow, warm air, odd noises, or short-cycling are early warning signs — better to catch them now than in July.
