The Top AC Problems That Cause Failures And Need To Be Repaired Soon


Soon, it will be time to turn your AC on, but there may be problems that you need to have repaired first. The most common air conditioner problems start before you ever turn your system on. Therefore, you probably want to know how to deal with some of the most common problems. The following top AC problems are issues you need to have fixed before they cause failures:

Damage to Condensing Unit

The condensing unit is the outdoor component of your air conditioning. It is also an area where a lot of problems begin before turning your system on. Some of the common condensing unit problems that need to be repaired include the following:

  • Damaged fins on the condensing coil
  • Damage due to storms and debris
  • Damage due to dirt and grime buildup

The damage to condensing units is often caused during the winter months. Therefore, you will want to inspect it for damage when doing spring maintenance. This will ensure these problems are fixed before you turn the AC on.

Issues With AC Fans

There are several fans with AC systems that can cause efficiency and cooling issues. Problems with fans can cause the system to not cool properly or reduce airflow at the HVAC vents. Some of the issues with AC fans that may need to be repaired include the following:

  • Damage to fan blades
  • Failing fan motor components
  • Fan motor failures (usually requires replacement)

The problems with the fans can be due to damage to the condensing unit or issues with the blower for ductwork. You will want to have these areas checked before you turn your system on.

Compressor or Condensing Coil Leaks

Another area where you may need to deal with common AC problems is the condensing coils and compressor. This is where refrigerant gases provide the cooling for your home. Therefore, you may need to check for leaks in these areas. Problems that can cause leaks and damage the compressor include the following:

  • Dirty AC units
  • Blocked condensation lines
  • Electrical component failures
  • Overcharged compressor

Leaks need to be repaired before your system can be charged to prepare for warmer weather.

Issues With Thermostats and Controls

There may also be issues with the HVAC thermostats that cause problems with your AC. These issues may affect the efficiency of your system or cause it to not work at all. Some of the problems with AC thermostats and controls include the following:

  • Failure of electrical controls
  • Wrong thermostat settings
  • Issues with thermostat wiring or backup batteries

Thermostats are a common problem when switching to cooling. Therefore, you want to make sure your thermostat is on the correct cooling setting before calling for help.

Problems With Ductwork and HVAC Dampers

Ductwork and dampers for HVAC systems can also cause problems with your AC. These issues can reduce airflow and affect the efficiency of your system. Problems with HVAC ductwork and dampers that need to be repaired include the following:

  • Jammed dampers
  • Leaks in ductwork and air handler
  • Closed vents and problems with HVAC vents

Automated dampers are a common problem with modern zoned HVAC systems because they can get jammed or stop working.

The problems with your AC will only get worse if you neglect the repairs and wait for your system to fail. Contact an AC repair service for help dealing with these issues before they become costly.

Talking About Electric Heating Systems

Hi there, my name is Shelley. Welcome to my site about electric heating systems. Electric heat has recently fallen out of favor due to the efficiency of natural gas systems. Electric heat is still suitable for small buildings that do not need the high temps provided by upgraded systems. I will use this site to explore all of the building types that can benefit from electric heating systems. I will also share information about system components, installations and repairs. I welcome you to come by often to learn more about this exciting topic. Thanks for coming by. See you soon.
