Your heating and cooling system is likely the most expensive appliance in your home, and it works nearly year-round in North Carolina. This checklist splits maintenance into what you can handle yourself and what genuinely requires a professional — season by season.
Monthly (5 minutes): check your air filter and replace it when it looks dirty — every 30–90 days for one-inch filters, sooner during spring pollen season or if you have pets. Walk around the outdoor unit and clear leaves, grass clippings, and debris, keeping two feet of clearance on all sides. Glance at vents and returns to make sure furniture or rugs aren't blocking airflow.
Every spring (before cooling season): rinse the outdoor condenser coil gently with a hose to wash off pollen and dust, check that the condensate drain line is flowing, test your AC on a mild day so you find problems before the first 90-degree week, and change the filter. Then schedule a professional cooling tune-up.
Every fall (before heating season): test the heat on a cool day and listen for unusual noises, check that flues and vents outside are clear of nests and debris, replace batteries in your thermostat and — importantly — your carbon monoxide detectors, and swap the filter again. Then schedule a professional heating tune-up.
What to leave to a professional: refrigerant levels and leak detection, electrical components and capacitors, heat exchanger inspection (a safety-critical carbon monoxide check), burner and flame sensor cleaning, blower motor service, ductwork evaluation, and full system performance testing. These require tools, training, and in some cases EPA certification — and they're where the real preventive value lives.
The reason this matters here: our systems cool from April through October and heat through winter, with humidity and heavy pollen adding strain most climates don't have. Homes that follow this checklist routinely get 15–20+ years out of equipment, while neglected systems fail years early.
If you'd rather not track any of this, that's exactly what our Energy Savings Agreement is for — two professional visits a year (spring and fall), priority scheduling, and repair discounts, so your system simply gets what it needs.
