The answer to 'how often to replace air filter' is that most HVAC experts recommend replacing your air filter every 1-3 months, or every 3 months at a minimum. This helps ensure your HVAC system is running efficiently and providing clean, healthy air to your home. The exact replacement frequency can vary depending on factors like the type of filter, the size of your home, and how much the system is used.
Replacing the air filter regularly is an important maintenance task for homeowners. Dirty, clogged filters can reduce airflow, make your HVAC system work harder, and even lead to more expensive repairs down the line. It's a simple and inexpensive way to keep your system running at peak performance.
