If there’s one thing we know for sure it is that we humans have grown accustomed to air conditioning in the hot and steamy Michigan summers! The need to replace a unit is generally quite apparent, as you’ll see in the list below. Keep in mind that repairs to fairly new AC units may still be covered under the manufacturer’s warranty, and routine maintenance checks can keep you from throwing money away because of mechanical inefficiency.
Decreased Cooling Capability
You’re cranking it up, but the air coming through your vents isn’t as cold as it once was, or isn’t cold at all.
Decreased Air Flow
If there is little or no air flow through your vents, your air conditioning compressor is failing. Decreased air flow in one room when others are fine are an indication of problems in your duct work, or the culprit might be a misbehaving thermostat unit.
Moisture around the Unit
You may have a broken or blocked drain tube if you see moisture anywhere, or water pools next the the unit. Leakage or ice forming on the unit can indicate serious problems.
Odd Sounds or Odors
Grinding, squealing, or grating noises indicate failure of some component of your air conditioning unit. Foul smells from your vents indicates the air conditioning wire insulation has burned out. Musty smells indicate mold inside your unit or ductwork, which can pose a significant health risk to your family.
