When most people think about an air conditioner filter, it is in terms of how efficient they are and how much dust they will stop. These are important things and should be considered when replacing or upgrading your air conditioner filter.

There is another very important job that your air conditioner filter does. It helps to keep dust from collecting on the evaporator coil of your air conditioning system. The evaporator is located inside the air handler and is one of the four main components of any air conditioning system. The air filter is usually located somewhere just before the evaporator coil.

Everyone knows that any dust that passes through the filter ends up back in your living space and can be very irritating to allergy sufferers and anyone else who is sensitive to dust and airborne contaminants.

What most people don’t realize is that your air conditioner filter also serves another important purpose. It also prevents the evaporator coil from becoming plugged with dust and reducing the efficiency of the equipment.

This evaporator coil is constructed very similar to the radiator in a car. Like your car radiator, it will not be able to do its job without proper airflow. I am comparing the evaporator coil to a car radiator because most of us know what a radiator looks like, but an evaporator coil works to cool air as it passes through.

Over time dust collects between the fins of the evaporator coil and can even form a layer on the surface of the evaporator coil fins (like a blanket). This happens over a period of time and can take months and even years to happen.

If you have your air conditioner serviced regularly, the technician will check this and advise you when it needs to be cleaned. As airflow through the evaporator coil becomes more and more restricted the equipment efficiency begins to decline. This can even cause equipment failure and lead to expensive repairs.

So, cleaner air is not the only benefit you will get from using an efficient air conditioner filter. You will also save money because your air conditioning equipment will perform at a higher efficiency.

A Quick Note From The Publisher... If you like the article above, you may be interested in the following article which is also related to HVAC... Heat Pump: Key to Your Heating and Air Conditioning A heat pump is simply an air conditioner that contains a valve allowing it to let you decide whether you want heat or cool air to circulate throughout your home. The heat pump valve can be adjusted based on your specific needs - providing you with a cool breeze or reversing its flow of Freon, located in the air conditioning refrigerant, and delivering a toasty feel to the room. The heat pump is an electric component that has come a long way from the proprietary gas furnace. Most people are at least familiar with heat pumps and how it can be a cost-effective way to provide the very best in central air conditioning . Depending on your climate and your heating and air conditioning needs, choosing an advanced heat pump system can range anywhere from $2,000 up to a top-of-the-line, more popular brand that is around $8,000. Some of the best heat pumps can be very expensive but are very quiet and are sure to give you more "bang for your buck." Maintaining your heat pump system so it can last you years, comes from taking care of the entire air conditioning system and air conditioning parts . Cleaning the air conditioning air filter at least once a month properly (some air conditioning systems now even have disposable air conditioning filters, ) doing an annual air conditioning inspection with a creditable air conditioning company , and simply paying attention to the heat pump thermostat are all ways to make your heat pump air conditioner last. If you are shopping around for a new heat pump thermostat , look for one that has a variety of features to deliver an overall performance that will give you the best in temperature control. There are two main types of heat pump thermostats and the options are simply based on preference. There are electro-mechanical and electronic...
