Many homes have inefficient filters that trap less than ten percent of the particulate that is drawn into heating and cooling systems. Once dust and debris overcome a standard household filter and begin to accumulate in the mechanical systems and ductwork, airflow is restricted, efficiency reduced, and air contamination is accelerated. The average six-room house accumulates 40 pounds of dust each year. That’s a lot for your air filters to handle. Talk to Lea Heating & Air Conditioning to make sure you’re utilizing the very best and proper filters for your HVAC equipment. Make sure to schedule yearly, comprehensive cleaning of your heating and cooling systems, as well as ductwork.
