Regular maintenance of an air conditioner is essential for ensuring its longevity and reliability. Without a proper tune-up, your unit could break down when you need it most. Regular AC maintenance includes cleaning or replacing filters to keep the inside of your unit clear of dust and debris, examining condensate drains to prevent clogging and overflow, checking refrigerant levels and pressures to ensure system performance, and checking the entire system for signs of wear or damage. A well-maintained AC can help save money on energy bills and reduce the risk of costly repairs in the future.
