10 Air Conditioning Problems You Should Know About

Seasonal changes and intense weather can harm your air conditioning system. From time to time, it is important to be aware of the common problems your AC may face and their solutions. Delaying maintenance or servicing can result in further damage, leading to costly repairs or replacement. You would never want your air conditioner to fail in the middle of a heatwave, right?

With some knowledge and understanding, you can avoid costly repairs and keep your air conditioning unit running smoothly all year. That is why we have compiled a list of the ten most common AC problems, their solutions, and how to spot them. Keep reading for some tips for preventive maintenance. 

  1. Air Conditioner Not Turning On

Your air conditioner not turning on can arise from a variety of issues, ranging from electrical failure to blockage. First, check the power source and circuit breakers if your AC unit is not turning on. The problem could be with the condensing unit or thermostat if everything seems to be running as it should.

  1. Air Conditioner Not Blowing Cold Air

If your air conditioner is running but not producing cold air, it could indicate low refrigerant levels or a clogged evaporator coil. The best way to diagnose and remedy this underlying problem is to have a professional HVAC technician from AccuTemp Refrigeration take a look.

Refrigerant levels are crucial as they help your air conditioner run effectively. Low refrigerant levels can severely affect the performance of your unit and lead to more costly repairs.

  1. Air Conditioner Freezing Up Outside Unit

Sufficient airflow is necessary for your AC unit to function as expected. Your outside unit may freeze up when the fan motor isn’t working properly or when dust and dirt build up in the condensing coils. Regularly cleaning and maintaining the fan motor to avoid this AC issue.

  1. AC Refrigerant Leak

The consequences of not spotting and fixing a refrigerant leak in time can be serious. If your AC unit has a refrigerant leak, it can’t cool the air properly and could cause further damage to other components in the system, like the compressor or evaporator coil.

Have one of our HVAC technicians at AccuTemp Refrigeration check your unit for signs of leaking as soon as possible if you suspect this to be the problem.

  1. Air Conditioner Making Noises

Unusual noises from your AC unit are usually a sign of something wrong. Grinding or rattling can signal a problem with the motor or fan, while squealing could indicate electrical failure.

Fixing these issues yourself is dangerous and could cause more damage to your AC unit. It is a good idea to always leave electrical issues to qualified technicians to avoid electrocution and fires.

  1. Frozen Evaporator Coil

Evaporator coils are crucial components of an air conditioner as they help absorb heat. Your AC’s evaporator coils may freeze if the air filter is clogged or the refrigerant levels are too low.

Inspecting and cleaning your AC unit’s filters on a schedule helps prevent this issue, along with other common AC problems, and solutions will be easier to implement. Also, check the indoor temperature setting, ensuring it is set no lower than 68°F.

  1. Electric Control Failure

This AC problem occurs due to electrical failure or malfunction of the thermostat. It causes your AC unit to start or stop cycling erratically, which, in turn, can cause the system to run inefficiently.

It can also be caused by a broken wire or loose connection, resulting in the system failing to start. The best way to diagnose this issue is via trial and error testing, with a technician helping you to identify the cause.

  1. Air Conditioner Leaking Water Outside

If your AC unit leaks water outside, it is likely due to an obstructed or broken condensate drain line. You can easily fix this issue by unclogging the drain line and replacing all damaged parts.

  1. Drainage Problem

Clogged or damaged drain lines are well-known issues among air conditioning problems. Water can leak into your home, leading to mold growth and other problems, if this issue isn’t repaired in time.

  1. Sensor Problem

System malfunction can occur if the AC unit’s temperature sensor is faulty or out of place. The sensor plays a crucial role in controlling your AC unit’s temperature settings and keeping it running efficiently.
