Two months of work, then months of sitting idle

Your air conditioner in Bath gets asked to run in July and August, then sits the rest of the year. Summer afternoons here average 76°F, which is mild, so the system isn't working against extreme heat when it does run.

The long stretch of not running is what catches up with it. A capacitor or contactor can weaken while the unit sits unused, and the first hot day you turn it on is when that weak part gives out. You'll hear it as a hum with no start, or the unit starts and then trips off. It's not the heat that gets your AC here. It's asking it to start after months of doing nothing.

A new air conditioner would save little on running costs in Sagadahoc County, so the repair decision comes down to the unit's condition.

  • An older air conditioner$200 a year

Estimates for a typical Sagadahoc County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Maine fuel prices and NOAA climate normals. Your home will differ.

Repair makes sense when a part like a capacitor or contactor has failed.

Replacement makes sense when the compressor has failed or the system uses R-22 refrigerant, which is no longer made.

Why is my AC not blowing cold air?
Most often the filter is clogged and starving the system of airflow, or the refrigerant level is low from a leak. A dirty filter makes the coil work harder until it freezes over, which cuts cold air even though the blower still runs. If the air coming out is warm and weak, check the filter first since that is the one thing worth looking at before calling someone out.
Why is my AC leaking water?
The drain line that carries condensation away is clogged or the pan underneath has rusted through. Your AC pulls moisture out of the air as it cools, and that water is supposed to run out through a drain line to the outside. When that line clogs with algae or debris, the water backs up and drips inside instead, usually near the indoor unit.
Why won't my AC turn on?
Check the thermostat batteries and the breaker first, since those cause more no-start calls than anything inside the unit. If both are fine, the capacitor that gives the compressor its starting jolt may have failed, which is common and won't fix itself. A contractor can test the capacitor and the electrical connections quickly once you rule out the thermostat and the breaker.
