The answer to 'air filter installation cost' is that the cost can vary widely depending on several factors. Generally, the cost to have a professional HVAC technician install a new air filter ranges from around $50 to $200 or more. The price is influenced by the size and type of filter, the accessibility of the filter location, and the labor rates in your local area.
Homeowners may be able to install some basic air filters themselves for a lower cost, but it's important to follow the manufacturer's instructions carefully. For more complex or difficult-to-access filters, it's best to hire a qualified HVAC professional to ensure the job is done properly and safely.
