Air Conditioning Problems Due to a Clogged Air Filter

Regular maintenance for your air conditioning system is something you need to have professionals handle. However, there are a few small maintenance tasks you can take care of on your own during the year, and one of them is making sure to clean or change the air filter for the AC once a month during periods when it runs on a regular basis, and every three months when it isn’t in regular use. The air filter will otherwise become clogged with debris, and this can cause some major troubles with the air conditioner.

If you need air conditioning repair in Fontana, CA due to air filter problems—or any kind of problems—simply call Avis Plumbing, Heating and Air. We have a long history of service to the Inland Empire when it comes to keeping air conditioners in great shape, so trust to us to restore and maintain your home’s AC.

What might go wrong due to a clogged filter

  • Reduction in airflow: The main purpose of the air filter on an air conditioner is to trap particles that enter through the return air vent and keep them from entering the AC’s cabinet. If the airflow from the return vents becomes blocked due to clogging in the filter, it will choke off airflow for the entire system. You will experience sluggish flow from the vents in the room and less comfort.
  • Frozen coils: If less warm air is reaching the AC cabinet, it will lead to the refrigerant in the evaporator coils remaining too cold. The warm air current across the coils is necessary for them to absorb heat, and if the refrigerant inside the coils doesn’t warm up, it will start to freeze water vapor along the coil. This ice buildup will start to block heat exchange, causing the air conditioner to lose cooling power. You need professionals to defrost the coils to get the AC working once again.
  • Damaged interior components: If a filter becomes heavily congested, it will start to let debris get through and inside the air conditioner’s cabinet. This can lead to numerous repair issues, but the most common is that dust and dirt across the blower motor will cause it to work with greater stress and may even burn out.

Routine changing or cleaning of the filter will help you avoid these problems. But you still need professional maintenance once a year to make sure your AC remains in top working order.
