Five months of Oak Ridge summer heat adds up
Your air conditioner works from May through September here, five months of afternoons that average 85°F. That is five months of the compressor cycling on and off, day after day, to keep up.
Anderson County has also seen 42 damaging wind events and 8 hail storms since 2015, one dropping a hailstone over an inch across. That kind of weather can bend the fins on your outdoor unit or knock it out of level, and a bent coil fin blocks airflow the system needs to cool the house. A tune-up checks the outdoor unit for that kind of damage, along with the refrigerant charge and the electrical connections that wear from five straight months of running.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
- What does AC maintenance include?
- A technician checks refrigerant charge, cleans the condenser coil, and tests the capacitor and contactor in the outdoor unit. Indoors, they check the evaporator coil and the condensate drain, since a clogged drain line can shut the system down or cause water damage. They also check the thermostat and airflow across the coil, and replace the filter if it needs it. Catching a weak capacitor or a coil losing its ability to transfer heat before summer means it does not fail on the first 85°F afternoon.
- How often does an air conditioner need maintenance?
- Once a year, ideally before the cooling season starts. Here that means getting it done before May, so the system is ready for the five months of cooling that run through September. A yearly check catches a weak capacitor, a low refrigerant charge, or a dirty coil before the unit has to work through a stretch of 85°F afternoons with a problem already in it.
- Is AC maintenance worth it?
- Yes, because most air conditioner breakdowns start as a small problem that maintenance catches early, like a capacitor going weak or a coil losing efficiency as it gets dirty. A system that runs unchecked works harder to do the same job, and that strain is what leads to a compressor failing or a breakdown mid-summer. With cooling needed here from May through September, a unit that is not maintained has five straight months to develop a small problem into a bigger one.
