HVAC maintenance is crucial for good indoor air quality (IAQ). It involves cleaning air filters, ducts, and system components like coils and fans. This maintenance removes contaminants, improves airflow, and ensures energy efficiency. Neglecting HVAC maintenance can lead to poor IAQ, higher energy costs, and system malfunctions. Regular maintenance creates healthier indoor environments and extends HVAC system lifespan. Visit https://limric.com/air-conditioning/ for more information.
