  1. hvac license in Tennessee: do you need one?

    Most states require an HVAC or mechanical contractor license; the federal EPA Section 608 certification is required to handle refrigerant nationwide. In Tennessee, the state board or agency that handles hvac licensing is linked below — check it, and your city or county business-license office, before you advertise or take a job. If Tennessee doesn't license hvac work at the state level, a local business license (and often liability insurance) is still expected.

  2. What it costs to start a hvac business in Tennessee

    Plan for $10,000–$40,000 (tools, gauges, recovery equipment, van, license, insurance) to get operational. On top of that: about $300 to form a Tennessee LLC, then an annual report is due (~$300), a free EIN from the IRS, and general liability insurance — a few hundred dollars a year for most solo operators.

  3. What a hvac business needs before day one

  4. Form the business in Tennessee

    You can operate as a sole proprietor with no filing, or form an LLC for liability protection — for hands-on hvac work most owners choose the LLC. The Tennessee LLC filing fee is about $300 and formation takes immediate online. Then get a free EIN, open a business bank account, and register for Tennessee sales tax if you'll sell taxable goods or services.

  5. What to charge for hvac in Tennessee

    Diagnostic fee $85–$150, then flat-rate repairs ($200–$1,500) or system replacement ($5,000–$14,000 installed). Maintenance plans at $150–$300/yr per system are the recurring-revenue engine. Check what the established hvac businesses in your city actually charge before you set your rates — pricing to undercut them is the fastest way to work the first year at a loss.

  6. Getting your first hvac customers in Tennessee

    Google + reviews, home-service marketplaces, and partnerships with home inspectors and realtors. Maintenance agreements create predictable revenue. Seasonal marketing (pre-summer, pre-winter) and financing offers convert bigger jobs. Sharply seasonal — first heat wave and first cold snap create weeks of backlog. Pre-season maintenance marketing (April, September) and financing offers on replacements are what level the year out.

  7. The mistake most first-year hvac owners make

    Chasing installs and ignoring maintenance agreements. The install revenue is lumpy and seasonal; the maintenance base is what pays you in the shoulder months and feeds you the replacement leads.
