Regular air conditioning maintenance keeps your system running efficiently and helps you avoid a breakdown during the first real heat wave of the summer. Some of it you can handle yourself — the rest is worth leaving to a professional tune-up visit.
What You Can Safely Check Yourself
Change or clean the air filter. A dirty filter is one of the most common causes of poor AC performance — it restricts airflow and makes the system work harder. Check it monthly during peak season and replace or clean it as needed.
Keep the outdoor unit clear. Make sure leaves, grass clippings, and debris aren’t blocking airflow around your outdoor condenser unit, and trim back any vegetation growing too close to it.
Check that vents and returns are unobstructed. Furniture or rugs blocking a supply or return vent reduce airflow and can strain the system.
Watch for warning signs. Unusual noises, weak airflow, warm air when it should be cool, or higher-than-usual energy bills are all signs your system needs a professional look.
What Needs a Professional Tune-Up
A proper AC maintenance visit goes beyond what’s safe or practical for a homeowner to do: checking refrigerant levels, inspecting and tightening electrical connections, cleaning the condenser and evaporator coils, testing capacitors and the compressor, and verifying the system is operating at correct pressures. Refrigerant and electrical work in particular require EPA certification and licensing — refrigerant is regulated, and the electrical connections inside an AC unit carry real shock hazard if handled incorrectly.
How Often to Schedule Maintenance
Most manufacturers and technicians recommend a professional tune-up once a year, ideally in spring before cooling season ramps up. Staying current on maintenance also helps preserve your manufacturer’s warranty, which often requires documented annual service.
