Your AC doesn't work hard here, but the weather still gets to it
Summer afternoons in Calais average 76°F, so your air conditioner isn't running flat out the way one in a hotter place would. That's easy on the compressor. But the unit still sits outside all year, through wind and hail, whether it's running or not.
Washington County has seen 67 damaging wind events and 7 hail events over the past ten years, with hailstones up to an inch. That kind of weather can bend fins on the outdoor coil or knock the unit out of level, and none of it shows up as a problem until the next hot stretch when you actually need the cooling. A tune-up checks the coil, the fins, and the pad the unit sits on, so a stretch of bad weather doesn't turn into a system that won't cool when you finally need it.

- What does AC maintenance include?
- A technician checks refrigerant level, cleans the condenser coil, and tests the capacitor and contactor that start the compressor. They also check the fan motor, inspect the wiring for wear, and change or clean the filter if that's not already part of your routine. Outside, they'll clear debris from around the condenser unit so it can pull air through the coil the way it's built to.
- How often does an air conditioner need maintenance?
- Once a year is standard, usually before the weather turns warm. Even with Calais summer afternoons averaging a mild 76°F, the coil and electrical parts still sit outside through wind and weather all year. A yearly check gives a technician the chance to catch a weak capacitor or a coil clogged with debris before it fails.
- Is AC maintenance worth it?
- Yes, because most AC failures trace back to something a technician would have caught. A capacitor that's starting to go, a coil coated in debris, low refrigerant from a slow leak. All of these show up during a routine check, long before they'd cause the system to quit. Calais has recorded 67 damaging wind events over the past ten years, and wind like that can blow debris into the outdoor unit or work a wiring connection loose without you knowing it.
