How to Start an HVAC Business: Key Steps for Success

Starting an HVAC (Heating, Ventilation, and Air Conditioning) business is a smart move—demand for installation, repair, and maintenance services remains strong year-round. Whether you're a qualified HVAC technician ready to go solo or you're planning to scale a small team, this guide covers the key steps to start and grow a successful HVAC business from scratch.


🔧 1. Gain the Right Qualifications and Licences

Before you start, ensure you’re properly trained and certified.

In the UK:

  • You must hold a City & Guilds NVQ Level 2 or 3 in Refrigeration and Air Conditioning

  • F-Gas certification (Category 1) is legally required to handle refrigerants

  • Get your business registered with REFCOM or an approved F-Gas register

💡 If you're in the US, check for state-specific licensing requirements, EPA 608 Certification, and HVAC contractor licences.


🧾 2. Register and Set Up Your Business

Choose your business structure:

  • Sole Trader – Simple and fast to set up

  • Limited Company – More protection and better for growth

You’ll also need:

  • VAT registration if turnover exceeds £90,000

  • Business bank account

  • HMRC registration (for UK tax and self-assessment)


🛡️ 3. Get Insurance and Legal Protection

Operating an HVAC business involves risk. Protect your company with:

  • Public Liability Insurance (essential)

  • Employers’ Liability Insurance (if hiring staff)

  • Professional Indemnity Insurance (optional but helpful)

  • Tool and Van Insurance

  • Health & Safety policy (required if you have 5+ employees)

💡 Consult a local insurance broker to get tailored coverage.


🧰 4. Buy Your Tools, Equipment, and Van

Start with the essential HVAC tools and work up from there:

Core tools:

  • Manifold gauge set

  • Vacuum pump

  • Leak detectors

  • Digital thermometer

  • Pipe cutters, flaring tools, brazing kits

  • PPE (gloves, eye protection, masks)

Also, invest in a reliable van or work vehicle for transporting equipment and refrigerants safely.


📋 5. Set Your Services and Pricing

Offer services based on your expertise and local demand:

  • Air conditioning installation and repair

  • Furnace and boiler servicing

  • Heat pump installation

  • Commercial and residential HVAC maintenance

  • Emergency repair services

💡 Use hourly rates, flat job pricing, or maintenance contract packages. Be competitive but profitable.


🧾 6. Set Up Quoting, Booking & Invoicing Systems

Use digital tools to manage jobs professionally:

  • Job management software (e.g., Jobber, SetJob, ServiceM8)

  • Accounting software (e.g., Xero, QuickBooks)

  • CRM system to track customers and recurring maintenance schedules

Create branded:

  • Quotes and estimates

  • Maintenance plans

  • Invoices and payment links
