SumZero PROTECT+

Welcome to
the family.

Your installation includes PROTECT+ extended labor coverage. Here's what that means and what to do if you ever need it.

From the Owners

This job has our name on it.

When we started SumZero, we had one rule: do the work the way you'd want it done in your own house.

That means showing up on time, doing the job right, and standing behind it — not because you'll take us to court, but because that's who we are.

PROTECT+ is us putting that in writing. If a covered component fails after the manufacturer's window closes, you call us. We come out. We fix it. You don't pay for the labor. No claims process, no third-party runaround.

Welcome to the family. It means something to us.

What's Included

Three layers of coverage — all active

From the day we finished your installation, you have three things working in your favor.

01

Manufacturer Warranty

Your equipment is registered in your name. Parts covered by the manufacturer — typically 5 to 12 years depending on the system.

02

Workmanship Guarantee

If anything is wrong with how we installed your system, we come back and fix it. Your job is documented and on file.

03

PROTECT+ Labor Coverage

When a covered component needs repair after the manufacturer warranty, we cover the labor. You call, we come out, you pay nothing.

A SumZero technician diagnoses the issue. If it's a covered component, we handle the repair.

You pay nothing for the service labor on covered repairs. The coverage period is shown on your plan documentation.

If you sell the home, PROTECT+ transfers to the new owner. Let us know and we update the record.

While You're Here

Two more things worth knowing

Your installation is covered. Here's how to get even more out of your relationship with SumZero.

Comfort Club

Keep your system running at its best

Club members get an annual inspection per system, priority scheduling, and discounts on every service call. $99 per system per year — and it's the best way to protect the coverage you already have.
