Step 7 | Post-Installation Care
We don’t walk away—we follow up, support you, and stand by our work
At SumZero Energy Systems, the job isn’t done when the system is installed. In fact, one of the most important phases begins right after the crew leaves your home. We ensure your long-term satisfaction by closing out permits, registering warranties, and checking in after the dust settles.
This is also where we introduce you to our Comfort Club, designed to keep your system running like new for years to come.
Permit Closures and Final Documentation
We take full responsibility for final inspections and town approvals. Once installation is complete, we:
- Schedule and manage any required inspections
- Handle communication with town officials
- Provide documentation as needed for Mass Save® rebate verification
- Finalize any compliance paperwork related to the system or electrical work
You don’t have to call the town—we do it all for you.
System Warranty Registration
We register all eligible equipment warranties directly with the manufacturer, giving you peace of mind and full coverage. You’ll receive:
- A confirmation of registration
- Warranty terms and expiration details
- Support contact info should issues ever arise
This step is often missed by other contractors, but it’s standard at SumZero.
Comfort Club Enrollment & Support
As part of your project close-out, we’ll invite you to join our Comfort Club—a premium maintenance program built for homeowners who want reliable performance, fewer breakdowns, and priority access to service.
Members receive:
- Biannual system tune-ups
- Discounted repairs
- Priority scheduling
- Full system performance checkups
It’s not just maintenance. It’s a plan for long-term peace of mind.
Follow-Up Check-In
You’ll receive a personal follow-up call from your Project Coordinator or a team member within days of the install. We’ll confirm:
- That your system is running as expected
- That all questions have been answered
- That you feel 100% satisfied with the experience
Why This Step Matters
Most HVAC companies leave you with a system and hope for the best. At SumZero, we stay involved long after install day. Because what happens after installation is just as important as what happens during it.
Did You Know?
Every SumZero customer receives a personalized post-installation call and support invitation—something most companies overlook entirely. It’s a small step that keeps long-term trust strong.
Comfort That Lasts Beyond Installation
You chose SumZero because you wanted more than just an installation—you wanted clarity, care, and confidence. Post-install care is how we deliver on that promise, long after the van has driven away.
