HVAC lead verification
HVAC contractors generate contact records through equipment installations, service agreements, maintenance plan enrollments, and emergency dispatch calls — each creating a record with slightly different contact capture standards and different expected lifespans of accuracy. A residential maintenance agreement customer entered three years ago may have sold the home; a commercial facility contact listed as the primary HVAC decision-maker may have changed roles or contractors. Service agreement renewal and equipment replacement campaigns both require reaching the right person, not just a record in a work order system.
What's hiding in your list
Commercial HVAC client contacts are particularly volatile because facilities management roles change through outsourcing, internal reorganization, and property sales — meaning the contact on a multi-year service contract may be three job changes removed from the current decision-maker.
Residential customer records in field service management platforms like ServiceTitan are populated at the time of the first job and rely on customers self-reporting address and contact changes, which rarely happens proactively between service calls.
Equipment replacement prospect lists derived from installation age data often rely on permit records or manufacturer warranty registrations as a source for contact details — data that can be five to ten years old by the time the replacement window arrives.

Frequently asked
How do we verify our service agreement customer list before annual renewal outreach?
Export your active agreement customer segment from ServiceTitan or your field service platform, upload to BounceBlock, and validate emails and phones before the renewal campaign begins. Flagging records with invalid email or disconnected phone ahead of the campaign gives your CSRs a targeted call list to update contact information for customers the automated renewal sequence cannot reach.
Can BounceBlock validate commercial facility contacts where the account has a company name attached?
Yes. For commercial accounts, BounceBlock validates the individual contact email and phone and also enriches the company record — checking whether the business domain is active and the company profile matches what your service records contain. This is useful for commercial HVAC contractors managing large building portfolios where account contacts change frequently.
We want to run an equipment replacement campaign targeting units installed over twelve years ago. How clean is that data likely to be?
Installation records that are twelve or more years old are likely to have significant contact decay — residential customers move, commercial contacts change roles, and email addresses from that era may no longer exist. Running the list through BounceBlock before any campaign investment gives you a realistic deliverability picture. The free 100-row preview at /signup lets you test a sample before committing to a full list clean.
