Regular filter replacement helps your heating and cooling system operate at peak levels and improves IAQ (indoor air quality) while extending the life of your equipment. It is important to change filters regularly to ensure proper airflow and to keep your home free from dust, allergens and germs. Depending on the type of filter you have, you may require monthly filter replacements. Your Legacy Mechanical Heating and Cooling Experts service or installation technician will recommend the ideal filters and replacement schedules for your unit(s).
