Two months of real heat, then long stretches of nothing

Summer afternoons in Waldoboro average 75°F, and the season only runs July and August. That is a short window for an air conditioner to do its work, but it also means the system sits idle most of the year. A unit that starts and stops after months of rest is more likely to hesitate or trip on the first hot day than one running steadily.

Lincoln County has logged 19 damaging wind events and 3 hail storms over the past ten years, with hail up to an inch. Wind can rock an outdoor unit on its pad or throw debris into the fins. Hail that size can bend them. Either way, the coil cannot shed heat the way it should, and the air coming out feels weaker than it used to.

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

  • A new one at the federal minimum, 13.4 SEER2$160 a year
  • An older air conditioner$170 a year

Estimates for a typical Lincoln 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 of the time the filter is clogged and starving the system of airflow, or the refrigerant level is low from a leak somewhere in the line. A dirty outdoor coil can cause the same thing, since it stops the unit from shedding heat properly. Check the filter first. If it is clean and you are still getting warm air, the system needs a contractor to check refrigerant charge and the coils.
Why is my AC leaking water?
The condensate drain line is probably clogged, which backs water up and sends it somewhere in the house instead of outside. It can also happen if the coil ices over and then melts faster than the drain can handle. Shut the system off so the ice can melt and check whether the drain line is blocked. If water keeps showing up after that, have a contractor look at the coil and the drain.
Why won't my AC turn on?
Start with the thermostat. Check that it has power, is set to cool, and the temperature is actually below the room temperature. If the thermostat looks fine, check the breaker for the outdoor unit, since a tripped breaker will keep it from starting at all. If the breaker keeps tripping, that points to a problem in the unit itself and a contractor should take a look before you reset it again.
