• Anyone who maintains, services, repairs or disposes of equipment that could release refrigerant must be certified under EPA Section 608, which matters for every HVAC startup. Source: U.S. EPA: Section 608 technician certification requirements
• An EIN from the IRS is free to get and is required once you hire employees. Most banks ask for one to open a business account. Source: IRS: Get an employer identification number

How to use the Plumbing and HVAC Business Launch Kit

1. Describe the business. Trade, name, city, service area, services, who you serve and why customers should call you.
2. Build the startup budget. Truck, tools, licensing, insurance, parts, website, software, launch marketing and a cash cushion.
3. Find your break-even. Monthly fixed costs, your pay goal, average ticket and margin give the jobs per week you need.
4. Pick your first marketing moves. Google profile, website, reviews, door hangers, partners and memberships.
5. Print the plan. Print it, save it as a PDF or download it to share with a lender, partner or spouse.
6. Work the checklist. Licensing, money, operations and the first 100 customers, ticked off as you go.

How to start a plumbing business

1. Get licensed. Most states license plumbers and plumbing contractors separately. Know which license lets you pull permits and run your own company.
2. Set up the business. Entity, registered name, EIN, business bank account and insurance before the first paid job.
3. Price from real costs. Truck, insurance and your own time cost more than most new owners expect. Build a price book from day one.
4. Get found. Verify your Google Business Profile, publish a simple website and ask every early customer for a review.
5. Stay lean. Buy the tools the work needs, not the tools you might need someday.

How to start an HVAC business

Everything above applies, plus two HVAC specifics. Refrigerant work requires EPA Section 608 certification for the techs who do it. And HVAC demand swings with the weather, so plan cash for mild months and offer a maintenance membership from the start, so spring and fall tune-ups keep the schedule full between peaks.

Plumbing business plan: what goes on one page

• What you do and where: services, customers and service area.
• Why people call you: one or two honest reasons, like a master license, same-day service or upfront prices.
• Startup budget: every cost, with a cash cushion.
• The numbers: gross profit per job, break-even jobs per week, revenue and payback at your target.
• First 100 customers: the marketing moves you will make.
• Milestones: jobs per week at month one, three and six.

A lender or investor may want a longer traditional plan. Start here, then expand.

HVAC business plan numbers: break-even in jobs per week

Break-even is easier to act on as jobs a week than as dollars. Add monthly fixed costs, marketing and the pay you need, then divide by gross profit per job. If the answer is eight jobs a week, you know exactly what the first months have to look like.

How to get plumbing and HVAC customers in the first 90 days

• Verify your Google Business Profile with the right primary category and real photos.
• Ask every one of your first customers for a review, by text, right after the job.
• Leave door hangers on the homes around every job.
• Meet realtors, home inspectors and property managers. They need reliable trades all year.
• Offer a maintenance membership on every invoice so first customers become repeat customers.
• Add Local Services Ads once you pass Google's verification checks, and answer every call live.

Then follow the 90-day Plumbing Marketing Playbook.

Plumbing and HVAC business names that work

The best trade names are easy to say on the phone, easy to spell and easy to remember on the side of a truck. Your last name or region plus the trade is a classic for a reason. Before you print anything, search your state business registry and the USPTO trademark database, and check the domain. The name tool in the kit gives you starting ideas.
