Why Timely Replacement of Filter Matters For Your AC Unit

The air filter in your air conditioner is not there to just keep the air coming out of it clean. In fact, the air filter plays an important role in helping your system work properly. Cleaning or changing the air filters is an important step in air conditioner maintenance. It helps in heading off a number of potential issues. It also helps in improving energy efficiency. You can also prevent costly air conditioning repairs.These are a few reasons why timely cleaning or replacement of dirty air filters matters so much:

Short Cycling

Every air conditioner is supposed to cycle on and off at intermittent intervals throughout the day. However, dirty air filters cause those cycles to become more frequent than they should be. This doesn’t just cause noise pollution in your Bay Area home. It also means uncomfortable temperature changes and wasted energy.

Freezing Up

Air can move freely through the unit with good and clean air filters. Dirty air filters tend to restrict the flow of air in the house. This can cause cold air to build up inside the air conditioner, which may lower its internal temperature. Cold air buildup will eventually cause ice formations on the evaporator and condenser coils. You don’t want this to happen since it will put immense pressure on the air conditioner. Your system will also experience more wear and tear.

Uneven Cooling

Restricted airflow is not good for any air conditioner. This is true even if the cold air buildup doesn’t result in freezing. You may notice uneven cooling in your home with hot and cold spots. This means you may end up paying more for lower comfort levels.

Allergen Buildup

You need to keep air filters clean if anybody in your home has allergy problems or suffers from asthma. Dirty air filters cause mold, mildew, and other allergens to spread throughout the house. These allergens can build in your air duct system. They will linger there for weeks and months even if you replace the dirty air filter. Forced air system will cause the allergens to be released in your indoor environment. A mold problem is a major drawback of clogged or dirty air filters.

Excess Wear and Tear

Air conditioners tend to last for a long time when they are maintained properly. Quality air filters can help in stopping dust and dirt from building up on the internal components of your unit. You may experience serious maintenance issues with a dirty, clogged, or bad air filter. Your unit will also suffer additional wear and tear. In the long run, you may have to replace the entire air conditioning unit before its time.

In the meanwhile, you may get slapped with high repair bills. These repair issues would never have cropped up if the air filters had not been dirty. This is an added expense that can be prevented by ensuring the air filters remain clean.

System Efficiency is Reduced

You are not saving any money if you are not getting your air filters replaced because of the added cost. You are only hurting your finances in the long run by doing this. Dirty air filters tend to reduce system efficiency, which increases utility bills.
