What does “non-prorated” mean?
It means the coverage never decreases. Whether it's year 5 or year 40, you have the exact same protection as on day one. Many competitors use pro-rated warranties where you pay an increasing percentage of replacement costs over time.
Is the warranty transferable?
Yes. If you sell your home, the full remaining warranty transfers to the new homeowner at no cost. This adds real resale value to your property.
What about the installation?
Our installation is backed separately. We also provide a free 3-year anniversary inspection where we visit your home to verify everything is still performing perfectly.
