5. Sensor problems. To keep a room comfortable, window air conditioners have a thermostat sensor behind the control panel, which measures the temperature of air coming into the evaporative coil. If the sensor is knocked out of position, the air conditioner can cycle on and off too often or otherwise behave erratically.
Of course, what Hutchinson is too polite to say is that you should have tested the AC well before the start of hot weather. Too often we hope for the best because we think it saves money.
So if your air-conditioning is operating just fine and dandy, you might want to make an appointment with your service contractor to check out the furnace before winter blows in.
Even if your air-conditioning is doing well, you probably are not enthusiastic about spending the arm and the leg needed to pay for comfort this summer. Owens Corning, the maker of that pink insulation, has these suggestions:
Program your thermostat — Homeowners can save energy and money using a programmable thermostat with the air conditioner to automatically adjust the setting at night or when no one is home. Waiting to turn on the air conditioner when you return home won’t cool your home any faster; it could result in excessive cooling and unnecessary expense.
