A dirty filter and evaporator coil mean your system uses more power and may reduce the system’s lifespan.
This may surprise you, but we don’t really like cleaning evaporator coils. For one thing they are difficult to get to being inside the house. But mostly, because simply it is often a service which could have been avoided and performed at a later time.
The primary reason air-conditioning and heating systems have filters is to reduce the amount of dirt and dust inside the system. Contaminants like this are tough on an air conditioner, straining the unit’s ability to cool the home.
HVAC filters are inexpensive and easy to replace. And be sure to use a quality pleated filter. The newer pleated filters are much more effective than the old style filters and are widely available.
Dirt buildup serves as both an insulator and restricts airflow, which prevents the evaporation coil from effectively absorbing heat inside your home, that heat transfer process is what keeps you cool at home. The evaporator coil draws heat out of the air inside of your home to cool it down. When it becomes dirty, it not only will severely cut down the total energy efficiency of the system, something you will notice with gradually increasing electric bills, it will also have an impact which can shorten the life-span of other components such as fan motors and your air conditioning compressor.
The most important maintenance task that will ensure the efficiency of your air conditioner, and your savings, is to routinely replace its filters. Clogged, dirty filters block normal airflow and reduce a system’s efficiency significantly. With normal airflow obstructed, air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil’s heat-absorbing capacity. Replacing a dirty, clogged filter with a clean one can lower your air conditioner’s energy consumption by 5% to 15% while keeping your evaporator coil cleaner and extending the time before it needs cleaning.
The benefits of frequently changing your filters:
- Helps maximize the air flow within your house
- Will serve to lengthen the lifespan of your air conditioning unit
- Saves you money on your electrify bills and service costs
How often to change your air filters can depend on the following:
- The type of air filter you are using, (please use a pleated filter)
- The overall indoor air quality
- How many pets are in the home
- The number of people occupying the home, and
- The level of air pollution and particulates like dust and pollen around the home
It is important to understand that the suggestion for how to replace the filter you see on the package is based upon a nationwide average.
Because of our very lengthy cooling season and the fact air-conditioning systems will run almost continuously during the hottest season, here are our suggestions for a air conditioning system filter change schedule in Bryan and College Station:
- Vacation home or single occupant and no pets or allergies: every 2 months.
- Average suburban home without pets: every 45 days
- Add a dog or cat: every 30 days
- Add more than one pet or anyone has allergies: 30 days and more often, particularly when in the heat of the summer.
Whether you have central air conditioning or room air conditioners, keeping the air filters clean can lower your AC unit’s electricity use by 5 percent to 15 percent, according to the U.S. Department of Energy. And since cooling your home is a big source of energy consumption, keeping your AC filters clean can help save money on your monthly electric bill.
A clean filter prevents the evaporator coil from soiling quickly. In time, however, the evaporator coil will still collect dirt. This dirt reduces airflow and insulates the coil, reducing its ability to absorb heat. To avoid this problem, check your evaporator coil every year and have it cleaned as necessary.
