AC & Air Conditioner Repair in Elko New Market, MN

AC repair calls in Elko New Market homes
Many air conditioners in Elko New Market are as old as the houses, which puts them in their late teens or twenties. At that age, expect run capacitors that bulge and fail, contactors pitted from years of cycling, condenser fan motors with dry bearings and, eventually, refrigerant leaks at the coil. Anything made before 2010 may hold R-22, and a refrigerant leak on an R-22 system that old rarely justifies the repair.
Some calls turn out not to be failures. A builder-sized AC that's too big for the house reaches the setpoint quickly and leaves the air sticky, which a blower-speed change can partly fix.

AC repair in Elko New Market: questions
Our Elko New Market AC shuts off for a while on hot afternoons, then comes back. Is something wrong?
Maybe not. If your air conditioner is enrolled in a utility cycling program, such as MVEC's Energy Wise or Xcel's Saver's Switch, the utility can turn the condenser off for short periods during peak demand. If it isn't enrolled, the usual suspects are a dirty condenser coil tripping on high pressure, a failing capacitor or fan motor, or an overheating compressor. Rinse the coil, and call if the shutoffs continue.
Our Elko New Market AC cools the house, but it still feels clammy. Is it too big?
Possibly. Builders often picked tonnage by square footage, and an oversized unit satisfies the thermostat in a few minutes and stops before the coil has had time to wring out much moisture. Setting the blower to a lower cooling speed, or using a dehumidify setting if the furnace has one, helps. At replacement, a Manual J usually lands smaller, and a two-stage unit runs longer, drier cycles.
