Defect of the Week

Three different houses in one week had furnace filters that were installed backwards. That doesn't sound like a big deal, but it really is. First of all, the filter itself is designed with wire or cardboard reinforcing on one side. If the filter is installed backwards, that reinforcement can’t protect the filter material from being sucked in towards the blower, which can cause serious damage to the blower. When installing your filter, check to see if there is an arrow on the edge of the filter. That arrow should point towards the furnace, not back into the return air duct.

Most people think the filter’s job is to keep the house clean. It does, to some extent. But, the filter’s most important job is to keep the blower and all of the interior parts of the furnace and air conditioner clean. That way they work more efficiently. A dirty filter restricts air flow through the heating and cooling system, causing it to overheat and age faster. So, change your filter regularly.

And, another thing to remember is that your "furnace" filter doesn't just work when the furnace is running. Most heating and cooling systems in houses run air through the filter for the air conditioner, too. So now is the time to check your furnace filter, look for the arrows indicating the direction of airflow, and make certain that it installed correctly. Or, have me check it when I'm inspecting the house for you. You will, literally, breathe easier.
