Presque Isle summers barely ask anything of your AC

Summer afternoons here average 74°F. That's mild enough that most homes get through the season with the air conditioner barely working, if it runs at all.

What wears on a system in Aroostook County isn't the heat, it's the weather that comes with it. The area has logged 161 damaging wind events and 56 hail events over the past ten years, with hail up to 2.5 inches. An outdoor unit sitting through that can end up with a bent fan, a cracked fan blade, or coil fins pounded flat by hail. You might not notice until the next warm stretch, when the system runs but can't cool like it should, or the outdoor fan makes a new noise it never made before.

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

  • A new one at the federal minimum, 13.4 SEER2$90 a year
  • An older air conditioner$100 a year

Estimates for a typical Aroostook 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?
The most common reason is a dirty air filter choking off airflow across the coil, which can cause it to ice up and blow warm air until it thaws. Low refrigerant from a leak is another common cause, and it will not go back to normal cooling until a contractor finds the leak and adds refrigerant. A failing compressor can also do this, since that is the part that actually cools the air. Check the filter first, since that is the one thing you can rule out yourself.
Why is my AC leaking water?
Most of the time this is a clogged condensate drain line, where the water that normally drips outside backs up and finds another way out, often through the ceiling or around the indoor unit. Algae and dirt build up in that line over time and block it. A dirty air filter can cause the same problem indirectly, since it lets the coil ice up, and the water shows up when that ice melts. A contractor can clear the line and check whether the drain pan or pump is also part of the problem.
Why won't my AC turn on?
Check the thermostat first, since dead batteries or a setting knocked off cool will stop the system before it ever starts. If the thermostat looks right, a tripped breaker is the next likely cause, and it is worth checking the electrical panel. Presque Isle has had 161 damaging wind events over the past ten years, and storms like that can trip a breaker or damage the outdoor unit's disconnect. If the breaker holds and the thermostat is set correctly, the problem is likely inside the unit itself, and that calls for a contractor to look at it.
