It is estimated that about half of all homeowners in the United States have a home warranty policy.1 This raises the question of whether HVAC filters are covered by these policies and what benefits they may provide to homeowners.


Home warranties typically cover most major household components like furnaces, air conditioners, heating systems, water heaters, refrigerators and other appliances. However, the exact items covered vary widely between companies and plans so it is important for consumers to read their individual agreements carefully before purchasing a plan. In general, most basic home warranties do not include coverage for HVAC filters but some higher-end plans may offer such protection.


The benefit of having an HVAC filter included in a home warranty plan would be that repairs or replacements due to normal wear and tear could be performed without any additional cost to the homeowner. While this type of coverage can sometimes add significant value to a home warranty plan, it should also be weighed against potential drawbacks such as increased monthly premiums or limited service providers available through the particular company offering the plan. Ultimately, each consumer’s situation will dictate which kind of policy makes sense for them and provides best overall value.
