How to check a provider’s FDNY listing

New York City requires companies that service commercial cooking exhaust systems to hold an FDNY company certificate, and FDNY publishes the approved companies. You do not need to take any directory’s — including our — word for a company’s status. Here is the check, in order.

1. The approved companies list

Download the FDNY’s Approved Commercial Cooking Companies List (a PDF, regenerated as companies are approved and renewed). It lists each company with its list number, address, phone, principal, insurance expiration, and approval expiration. Check three things:

• The company appears, under a name you can match (LLC punctuation varies).
• The approval expiration is in the future — approvals renew annually, and the list shows the date each company is approved through.
• The list’s own date is recent; a company missing from a fresh list may have let its approval lapse, or renamed.

2. What the approval means — and what it does not

The company certificate exists so that the principal behind the company has documented field experience and holds a Certificate of Fitness (W-64 or P-64), and so the company keeps insurance records current with FDNY. An approval tells you FDNY’s records show the company in this category on a given date. It does not tell you whether a specific crew does careful work, shows up on time, or cleans up — that is what references, written scope, and our quote comparison are for.

3. Precipitator endorsements

Some kitchens have electrostatic precipitators (ESP units) in the exhaust path. Servicing them is a separate endorsement: the list shows which precipitator manufacturers each company is approved for, and who holds that endorsement. If your kitchen has an ESP unit, filter for companies with precipitator service and confirm yours is a covered manufacturer.

4. The disciplined list

FDNY also publishes a list of disciplined companies and individuals. It is worth a look before you sign, the same way you would check any contractor’s record.

5. Outside the five boroughs

An FDNY approval is a New York City credential. New Jersey and Connecticut run their own programs for fire-protection contractors — a NYC-listed company can be legitimate and still not hold the credentials it would need to service your location across state lines. Ask a company directly what credentials cover your address.
