Methodology
Two independent rankings, no composite score. By location count: total locations operated across Delaware (the chains and aggregators). By revenue and popularity: total review count across web and social channels (the cleanest available popularity proxy). Each row rolls up one HVAC company across all their locations.
HVAC company records draw from 12+ public and private data sources, refresh weekly, and are independently verified against at least two of them, including state license rosters from the Delaware Medical Board and publicly available business records. Owner contacts come from a separate 20+ source scan and refresh monthly.

Common questions
Why use review count as the popularity proxy?
HVAC company revenue is notoriously hard to find publicly: most HVAC companies are independent, privately held, and don't publish financials. Review count is the cleanest available proxy for size and how established a business is, so the HVAC companies with the most reviews are typically the ones running the most volume.
Where are most Delaware HVAC companies concentrated?
Top Delaware HVAC company clusters by review volume: Newark, Wilmington, New Castle, Frankford. Orbital tracks 204 active HVAC companies across the state. 33 of them operate multiple locations.
How many HVAC companies are in Delaware?
Orbital tracks 204 active HVAC companies across Delaware. 33 operate multiple locations, accounting for the bulk of locations across the state.
Who is this list for?
B2B vendors who sell into HVAC companies: equipment manufacturers, parts and refrigerant distributors, field service management software, fleet and dispatch software, capital providers, M&A brokers, marketing agencies, and professional services. It is not a consumer directory and is not optimised for booking appointments.
How do I get owner contact info (mobile phone, email) for these HVAC companies?
Every HVAC company on the list has verified owner / GM contacts available upon signing up with Orbital. You get mobile phones, work emails, and decision-maker titles, not generic front-desk numbers. Contact records come from a separate scan of 20+ public and private data sources, independently verified before unlock, and refreshed monthly.
How often does the data refresh?
HVAC company records refresh weekly. Contact records refresh monthly. New HVAC companies that pass two-source verification get added on the next refresh, and HVAC companies that drop signals get flagged in the platform but are not silently removed from list snapshots.
