What Does “Licensed and Insured” Really Mean for Plumbing & HVAC Services?
Many homeowners assume “licensed and insured” is just marketing fluff—but it’s actually a critical safety and legal requirement in New York.
Licensed: In New York, plumbing and HVAC contractors must hold valid licenses issued by the Department of State (DOS). For plumbing, this typically requires 5+ years of apprenticeship and passing a state exam. HVAC technicians often need EPA Section 608 certification to handle refrigerants legally.
Insured: This includes general liability insurance (covers property damage or injuries) and workers’ compensation (protects you if a worker gets hurt on your property).
⚠️ Did you know? According to the U.S. Bureau of Labor Statistics, nearly 15% of construction-related injuries involve HVAC or plumbing work. Hiring an uninsured contractor could leave you financially responsible.
How to Verify a Plumbing/HVAC Company’s License & Insurance in Hicksville
Don’t just take their word for it. Follow these 3 concrete steps:
Check the New York DOS License Search Visit https://www.dos.ny.gov → “Professional Licensing” → Search by business name or license number. Look for “Active” status and correct trade classification (e.g., “Master Plumber” or “HVAC Contractor”).
Request Proof of Insurance Ask for a certificate of insurance (COI). Call the insurer listed to confirm it’s current and covers at least $1 million in liability.
Read BBB & Google Reviews Look for patterns: Do multiple reviews mention “licensed,” “on-time,” or “fixed it right the first time”? Avoid companies with repeated complaints about unlicensed work.

The risks are real—and costly:

Fines: NY State can fine unlicensed contractors up to $5,000—but you could also be penalized if you knowingly hired them.
Safety Hazards: Improper gas line installation or electrical HVAC work can lead to carbon monoxide leaks or fires.
