An HVAC company installs, repairs and maintains heating, cooling and ventilation systems. When a furnace fails in January or the air conditioning dies in July, the homeowner calls the same day. That urgency is what makes the business resilient when other home spending slows.
It is part of the home services industry. The Bureau of Labor Statistics projects HVAC technician jobs to grow 8% from 2024 to 2034, and the median wage was $61,010 in May 2025, so skilled people are in demand.
Who it suits
Experienced HVAC technicians ready to run their own company. This is not a business to learn on the job. Most owners spend several years as technicians first.
Licensing comes first
Most states require an HVAC or mechanical contractor license, often with proof of experience and an exam. Anyone who handles refrigerants needs EPA Section 608 certification. Some cities add their own permit rules for installations. Check with your state licensing board before you take your first job.
Startup costs
A service van, diagnostic tools, refrigerant recovery equipment, a parts inventory, licensing, insurance and dispatch software. You can save money with a used van and by buying parts as jobs come in.
How it makes money
Three streams: emergency repair calls, system replacements (high ticket, lower frequency) and maintenance plans. A plan where customers pay yearly for two tune-ups plus priority service builds predictable revenue and fills slow seasons.
How to grow
Hire your first technician once you are turning down work. Hiring is the hardest part, so pay competitively and consider training apprentices. Many owners also partner with home builders or property managers for steady volume.
Watch out for
Seasonal swings between peak summer and winter and mild spring and fall months. Plan cash flow around them, and use maintenance visits to keep technicians busy in the shoulder seasons.
