Dirty air filters cause a heating and cooling system to work harder and break down faster. That’s because unfiltered dust and grime works into parts, creating friction that causes unnecessary wear and eventually failure.
How much does a dirty air filter cost you?
- Reduced air flow in the home, leading to up to 15% higher operating costs
- Leads to costly duct cleaning or replacement
- Lowers system efficiency
To avoid these expenses, change filters monthly when your heating and cooling system’s in regular use. Discuss cleaning the unit and ductwork with your heating and cooling service professional.
