Importance Of Changing Filters Regularly
Changing filters regularly in your Lennox furnace safeguards your indoor air quality and optimizes furnace performance. A clean filter traps dust, pollen, and allergens, reducing the probability of respiratory issues. When you neglect filter changes, these contaminants accumulate, worsening indoor air quality.
Regular replacement enhances energy efficiency. Clogged filters force your furnace to work harder to maintain your desired temperature, leading to higher energy bills. A new filter improves airflow, allowing your furnace to operate smoothly.
Changing filters also prolongs your furnace’s lifespan. Overworking the system due to a clogged filter can lead to mechanical failures. By maintaining clean filters, you help avoid costly repairs.
Aim to change your filters at least every three months, or monthly during peak usage seasons. Always check your filter for signs of dirt or wear. This proactive approach ensures comfort and energy savings in your home.
