Brand-agnostic
The discount comes from the install, not the brand
Every device we install is carrier recognized. The discount comes from the certified install and the documentation, not the brand. We match the device to your home, your plumbing, and your carrier's approved list during the 15-minute assessment.
Understanding which insurance form you carry (HO-A, HO-B, or HO-3) matters because the form determines whether your claim settles at replacement cost or depreciated value.
