When the cooler temperatures finally stuck around, you were thrilled.

Finally, those of us who live in warmer parts of the United States wouldn’t have to sweat just stepping out of our cars. We are happy to give our air conditioners a break. On a related note, we can also get a vacation from higher than normal utility bills—at least for a few months.

We know what you might be thinking. “What? There’s another filter in my home?”

Well, it depends. Here in Texas, the filter that’s working during the winter months is typically just your air duct return air filter, the same one you regularly change for your air conditioner. What you might not realize is that it is just as important to change this filter when you turn on the heater in your home as during the summer months.

In colder parts of the country, some homes may have a warm air furnace. In these units, a dedicated furnace filter is typically … Read Full Post »
