A CHANGE for the BETTER Swap out your HVAC system filter to save energy and money


W


hen it comes to energy efficiency in the home, sometimes small changes can make a big impact. A small, unglamorous task like changing the filters on your HVAC system makes your unit run more efficiently – keeping your house cooler in the summer and warmer in the winter. It also saves money. And the savings gained from having your system run more efficiently can be applied to more fun or entertaining pursuits that your family can enjoy together.


The lowdown on dirt


As you move around your home, you drive dust into the air from carpets, furniture and drapes. Regardless of where it comes from, dust and dirt trapped in a system’s air filter leads to several problems, including:


• Reduced air flow in the home and up to 15 percent higher operating costs


• Costly duct cleaning or replacement • Lowered system efficiency


MAINTAINING YOUR AIR CONDITIONER


Routinely replace or clean your air filters. This can lower your AC’s energy consumption by 5-15 percent.


Check your AC’s evaporator coil every year and clean it as necessary.


If your coil fins are bent, use a “fin comb” to straighten them.


If you have a split system, be sure to clean debris and leaves from the fan, compressor and condenser.


Making the switch


Now, that you know the facts, it’s time to get busy changing or cleaning the air filter in your heating/cooling system. Many HVAC professionals recommend that you clean or change the filter on your air conditioner or furnace monthly. It’s simple and easy, and in many cases, it only takes a few minutes.


Filters are available in a variety of types and efficiencies, rated by a Minimum Efficiency Reporting Value (MERV). MERV, a method developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers, tests filter effectiveness. The higher the MERV number, the higher the filter’s effectiveness at keeping dust out of your system. While most types of filters must be replaced, some filters are reusable. And don’t forget about the winter months. Your heating system needs to work as efficiently as possible to keep you warm (and your loved one feeling snuggly), and a clean air filter helps it do just that.


Annual maintenance can improve your comfort and increase efficiency and life of your air conditioner.


 Occasionally pass a stiff wire through your unit’s drain channels to prevent clogs.


For window air


conditioners, inspect the window seals to keep cool air from escaping.


If you aren’t confident in performing maintenance chores, hire a pro.


Heating and cooling professionals recommend turning your system off before changing the air filter. Make sure that the arrow on the filter – which indicates the direction of the airflow – is pointing toward the blower motor. When you’ve made the change, turn your system back on.


A teachable moment


Beyond saving money and improving the air quality in your home, changing your air filter is a great opportunity to teach your family more about energy efficiency. Consider getting everyone involved, and the entire family will learn how simple changes can make a big difference.
