Your HVAC system should be professionally maintained twice a year, once in the spring before heavy air conditioning use and once in the fall before heating season. Regular maintenance helps your system run efficiently, prevents breakdowns, and extends the life of your equipment.

If your system freezes, turn the system off and allow it to thaw completely before running it again. Frozen coils are often caused by restricted airflow, dirty filters, or refrigerant issues, so it’s best to have a professional technician inspect the system.

First check your thermostat settings, circuit breaker, and air filter to make sure everything is functioning properly. If the system still isn’t running, it’s best to call a qualified HVAC technician to diagnose and repair the issue safely.

Most air filters should be changed every 1–3 months depending on the filter type and your home environment. Regular filter changes improve airflow, help your system run efficiently, and keep the air in your home cleaner.
