How to start an LLC for a HVAC business
HVAC contractors handle refrigerants regulated by the EPA, gas furnaces and electrical work, often in attics and crawl spaces. Claims range from carbon monoxide to water damage from a clogged condensate line. An LLC holds the mechanical license, the trucks and the service plans.
Our registered agent is optional: $74.25 a year, the same at renewal. Questions first? Ray or Vinny picks up at (954) 470-8356.

Why HVAC business owners form an LLC
Carbon monoxide and gas
Furnace installs bring the most serious claims.
Condensate leaks
Water damage from AC drains is common.
Heat and attic work
Crew injuries in extreme heat are a workers' comp risk.
An LLC keeps the company's debts and claims away from your personal assets when you run it as its own business: its own bank account, contracts signed in its name, and no mixing of money. It does not cover your own negligence, and lenders often ask for a personal guarantee. Insurance comes first.
