We know you\u2019ve heard this before. You should change the air conditioner<\/a> filter in your home about once a month, or at least, every three months. Often, a reminder to change a home\u2019s air conditioner filter is met with a groan. Many people see it as a chore that\u2019s somewhat optional, or that can be put off for a long period of time if needed.<\/p>\n\n\n\n

That\u2019s because so many people don\u2019t realize how an air filter actually works or the damage a dirty filter can do. It\u2019s not just about your air quality. Dirty air conditioner filters can actually waste energy and lead to the early demise of your air conditioner! Regular filter changes are a key part of air conditioner maintenance, helping to improve efficiency, extend the lifespan of your system, and ensure optimal performance.<\/p>\n\n\n\n

Neglecting maintenance of the entire AC system can lead to a decline in performance and increased energy use. A clean air conditioner runs far more efficiently than a dirty one. Annual maintenance is essential for ensuring all parts of the air conditioning system are operating within their proper specifications. Learn more in today\u2019s guide, and stock up on filters. Changing your filter is a simple task that is worth it in the long run.<\/p>\n\n\n\n\n\n\n\n

The filter serves as your air conditioner\u2019s bodyguard<\/h2>\n\n\n\n

An air filter actually protects your air conditioner from damage. If particulates in the air were able to freely move throughout your air conditioner, it could pummel the system, damaging the blower motor and one or more components such as coil fins or the blower unit, especially if airflow is restricted. Dirt and debris can also accumulate on coil fins, which may block airflow through the system and reduce efficiency. Inspecting AC coils and fins is essential to maintain system efficiency. Regular maintenance of coil fins ensures your air conditioner operates at peak performance. Since larger particulates are trapped in the filter, it cannot do such damage to the blower unit.<\/p>\n\n\n\n

Many people see an air filter primarily as a way to keep their air clean, eliminating many allergens like pollen and pet dander from the air they breathe every day. While this is true, in part, it\u2019s not the air filter\u2019s primary purpose. The air filter was designed to protect your equipment, first and foremost, which is why you may need a more powerful filter if clean air is your goal. Ask a local technician whether an air purifier<\/a> should be added to your HVAC system.<\/p>\n\n\n\n

A clogged filter does its job too well<\/h2>\n\n\n\n

A clogged air filter will still block particulates from circulating throughout the HVAC system. But that\u2019s because it blocks air from circulating as well! That means, first of all, that you\u2019ll feel a lot less comfortable.<\/p>\n\n\n\n

Maintaining optimal airflow is crucial for system efficiency, comfort, and the longevity of your HVAC equipment. Homeowners should replace filters regularly as part of routine AC maintenance, as filter replacement is key to maintaining system efficiency. Maintaining an air conditioner requires monthly air filter changes every 1\u20133 months, and the outdoor condenser unit should be kept free of debris with 2 feet of clearance.<\/p>\n\n\n\n

Air may not be able to make it through a blocked filter the way it\u2019s supposed to, and this will cause a lot of problems for your air conditioner. Since the system was designed for a certain amount of airflow and sized for your home\u2019s particular needs, you can expect some problems to result from an air conditioner that is not getting the correct airflow. When the system starts, pay attention for any strange noises, as these could indicate underlying mechanical issues that need professional attention.<\/p>\n\n\n\n

A blocked filter causes financial stress and discomfort<\/h2>\n\n\n\n

Some amount of dirt will accumulate in your air filter with time, even if you rarely use the air conditioner. The blower fan will still attempt to suck in air through the clogged filter in order to reach the temperature setting on the thermostat. Of course, it will come up short. The air conditioner must keep running much longer than it normally would, which means\u2026<\/p>\n\n\n\n
