Don't Ignore These Warning Signs of a Broken Air Conditioner

Indicators the Old AC Needs Repair or Replacement

Summer is one of the worst possible times to have a broken AC. Unfortunately, due to the heavy usage during the hottest months, that is when they tend to break down. If homeowners know the symptoms that point to a need for AC repair, they can get the problem dealt with before it becomes an emergency. The signs below indicate a home may need air conditioning repair or AC replacement.

Sign #1: The House is Too Warm

This symptom can be disguised by or attributed to the heat outside. Sometimes when it is exceptionally warm, an air conditioner may have trouble keeping the home at optimal temperature. Still, it should not be hot in the home, no matter the temperatures outside. If an air conditioning unit is having significant trouble keeping the home at a comfortable temperature, there may be a need for air conditioning replacement. Even if the whole unit does not need to be replaced, several things could be wrong.

• Clogged or dirty air filter
• Air duct damage or obstruction
• Malfunctioning blower
• Coolant leak
• Short cycling

Sign #2: Energy Bills are Through the Roof

Just how long has that HVAC unit been there? As any appliance or machine ages, it gains wear and tear and loses efficiency. This means the machine will work much harder to reach the same comfort level within the home. More energy use means that utility bills will spike. The unit may experience overheating issues, which can lead to other problems. Though pieces can be replaced, there is sometimes so much use that replacing all the necessary parts is more expensive than replacing the whole unit. If a homeowner has seen a significant increase in their bills without a significant increase in usage, then there is likely a problem with the system’s efficiency.

Sign #3: Unpleasant Sounds or Smells

Another indicator of a problem with the unit is when it starts making strange noises or strange smells coming from the vents. Many problems like this can be fixed by a professional fairly easily, while others may require a more significant repair or complete replacement.

• Banging: A banging sound can indicate that something has come loose within the unit and may be caught in a moving part. If not dealt with, it can cause more damage within the unit.
• Whistling or Hissing: This can be a sign of a leak. This can be in the air ducts or, more seriously, in the coolant tubing.
• Musty Smells: If the unit is not draining properly, it can lead to moisture buildup, and mold or mildew may begin to grow. This can stem from several problems, including dirty air filters and ducts.
•  Burning Smells: This can be due to an electrical issue and should be dealt with immediately.
