🏠 August Home Check: Change Your HVAC Filter

With the AC running non-stop this time of year, a dirty filter can strain your system and drive up energy costs. Check your filter monthly and replace it if it looks dirty.

Claim Avoided: A homeowner's overworked, neglected AC unit overheated and caused an electrical fire after months without a filter change.

A quick check today can save you from a costly repair.

"I really appreciate the help I received when looking for new homeowners insurance back in 2020. Not only did they recognize my need for a many updates in my policy, but they saved me money in the process. Recently, my agent, Doris, looked into other policies that would benefit my needs (without my prompting). Upon doing so, she found a way to reduce my premium on both homeowners and vehicles policies. Her customer service is beyond what I expected!"
