How to Start an HVAC Business
Starting an HVAC business requires more than technical skill. Licensing, insurance, business formation, pricing, and customer acquisition all need to be in place before you can operate legally and profitably. This guide covers the key steps — and Metrix Score can evaluate where you stand on each one.
Check your readiness first
Before diving into the steps, see where you stand today. The free Metrix Score assessment evaluates your HVAC business readiness across six categories.

HVAC contractor licensing varies by state. Most states require a specific mechanical or HVAC contractor license, often with experience and exam requirements. Check your state licensing board for current requirements.
2Get your EPA certification
If you handle refrigerants, EPA Section 608 certification is federally required. This is separate from your state contractor license.
3Form your business entity
Register an LLC, corporation, or other legal entity. This separates personal and business liability. Obtain your EIN from the IRS.
4Secure insurance
General liability insurance is essential. Workers compensation is required in most states if you have employees. Commercial auto and tools/equipment coverage protect your assets.
5Set up your finances
Open a business bank account, set up accounting, and establish a pricing structure that covers your costs and target margin. HVAC service calls, installations, and maintenance contracts each need separate pricing models.
6Define your services and market
Choose between residential and commercial, new installation and service/repair, or a mix. Define your service area and target customer. Specialization often outperforms being a generalist early on.
7Build your customer acquisition system
Referrals, online presence, Google Business Profile, and relationships with general contractors and property managers are common starting points. Track what works and invest accordingly.
8Establish supplier relationships
Equipment distributors, parts suppliers, and refrigerant sources need to be established before your first job. Negotiate terms and credit where possible.
