Our Process
At SumZero, we prioritize a seamless customer experience throughout the process, from the initial call to the final walkthrough, ensuring clarity and comfort with our high-performance heat pump systems:
90-Min Consultation & Site Survey
Your journey begins with a comprehensive home visit where we evaluate your current system, energy usage, and insulation levels. We assess feasibility, introduce the Mass Save® program, and gather detailed load data to build a system around your home—not a template. During this visit, we will conduct a thorough evaluation of your existing energy system, including your current energy consumption patterns and the insulation levels of your home. This assessment allows us to determine the feasibility of implementing energy-saving solutions and introduce you to the benefits and incentives offered by the Mass Save® program.
As a crucial part of this evaluation, we will collect comprehensive load data specific to your home. This data will enable us to design a customized energy-saving system that is tailored to your unique needs and requirements, rather than relying on a one-size-fits-all approach.
Custom Design & Proposal
We specialize in creating a custom heat pump solution that is specifically designed to meet the unique layout and performance requirements of your home. Our comprehensive proposal will not only include an optimized system design tailored to your needs but also highlight rebate-eligible options that can help you save money. Additionally, we provide a clear and detailed step-by-step breakdown of your installation journey, ensuring that you are well-informed and comfortable throughout the entire process.
Client Onboarding
We meticulously align the project timeline, establish key milestones, and assign a dedicated Project Coordinator who will be your main point of contact throughout the process. This crucial phase is where we schedule installation dates and walkthroughs, initiate the necessary permits and rebates, and begin constructing the comprehensive project file. This file is essential for ensuring that every aspect of the project is organized and ready, ultimately leading to a seamless and efficient execution of your project from start to finish.
Mass Save® Kickoff
Navigating the Mass Save® program can often feel like a daunting task, but we are here to simplify the experience for you.
Our dedicated Concierge Team takes care of every aspect of the process, ensuring a seamless journey from start to finish.
We handle everything from scheduling assessments to submitting all necessary paperwork on your behalf. Additionally, we assist you in applying for the 0% HEAT Loan, and once your project is completed, we take care of processing the rebate documentation for you, making it hassle-free.
Project Designer Walkthrough
Prior to the installation process, a dedicated SumZero Project Designer will come to your home to verify the final placement of your project. During this visit, they will address any questions you may have and ensure that no detail is overlooked. This thorough approach guarantees that you have complete clarity and confidence in the project before any work begins, setting the stage for a successful outcome.
Installation Execution
Our dedicated installation teams are committed to providing clean and efficient work while ensuring minimal disruption to your daily routine. Once the installation is complete, your system will be thoroughly commissioned and tested. We will then guide you through a comprehensive system walkthrough, ensuring you are fully acquainted with its features and functionalities.
Post-Installation Care
We take care of closing out all necessary permits, registering warranties for your peace of mind, and enrolling you in our exclusive Comfort Club, which provides ongoing maintenance services. Additionally, we make it a priority to follow up with you to ensure that you are completely satisfied with our services. We also extend an invitation for you to join our referral community, where you can connect with others and share your positive experiences.
