Heat Cool in Louisville
Homeowners in Louisville, especially in the winter when the weather is dry need to change their furnace filters at 
least every other month. A furnace in Louisville goes back and forth: heat cool, heat cool and can attract serious dust and dirt. Don’t bother checking it, just change it. You would not believe the downside of a dirty filter. It could cost you thousands of dollars not including the extra energy your system needs to heat your home. In Louisville our extreme temperatures put a real load on the heating and especially the cooling systems. Why does a filter need to be changed?
Proper airflow through your system. Clogged filters hamper airflow, forcing your furnace to work harder to preserve your preferred temperature. In general, airflow restrictions due to dirty filters is what cause evaporator coils to ice up, equipment to run longer than it should have to, and eventually lead to cracks in heat exchangers aka thousands of dollars!

- Locate your old furnace filter behind a panel in your furnace that either slides out or can be removed when you loosen a set of screws.
- Remove the dirty filter and, write down the dimensions. Go to the store and buy at least five new filters. This will help you change them more often because it will be easy.
