Given the high cost and expenses incurred in operating the unit, it's important that you keep the unit serviced regularly.
An important part of the air conditioner is the filter. It prevents dirt from getting inside the system and doing major damage to the unit. Knowing more about the air filter will help in making the right decision regarding the unit. Here are some important facts that you should know about air conditioning filters.
1. Not all air filters are the same
Some people presume that only one type of filter is installed in the air conditioner. The reality is that there are many sizes and types of filters. Some are reusable after cleaning while others are for one-time use only. The filters have different ratings and prices. A professional technician can tell you about the recommended filter for your air conditioner.
2. You need to inspect your air filter regularly
An air filter collects dirt and dust over time and therefore must be cleaned regularly. The EPA recommends that you inspect your AC filter at least every 3 months. In case you reside in a dusty area, or there are pets or children inside the house, you should consider getting the filter inspected every month. Regular inspection will ensure that a clogged filter won't result in damage to the unit.
3. Bigger is not always better
Keep in mind that only a specific size of filter will be suitable for an air conditioner. Going out and buying the biggest filter is not recommended. Installing a wrong size of air filter will result in inefficient filtering of the dust particles. This will result in accelerated wear-and-tear on the system. Again, a professional technician will guide you in buying the right size of filter.
4. Don't always just default to the highest rating
Every air conditioner requires a filter with a particular Minimum Efficiency Reporting Value (MERV) rating. Knowing that the highest rating is 16, some people buy the highest-rated filter. But the fact is that a filter with a higher-than-required filter might actually restrict air flow. This will strain the air conditioner and may cause damage to the system. That brings us to our final thing to consider…
5. Let a professional do the work
Filters should be installed, inspected, and cleaned by an experienced technician. Some people, in order to save money, try to clean the filter by vacuuming it. Others try to wash the filter in the washing machine. However, DIY cleaning often damages the filter. An experienced technician has the required tools and equipment to clean the filter safely.
The professional will also thoroughly clean the filter to prevent the buildup of bacteria and mold. These can enter the rooms through the vents thereby posing a health risk to the household.
