How to start an HVAC business
HVAC businesses can earn from tune-ups, repairs and equipment replacements, but those jobs consume different kinds of time and cash. Decide whether you're starting as a service company or an installation company. It is hard to do both well if one technician handles every hot-day call and every scheduled job.
Before you spend on ads
What to figure out first.
Pick your first offer
Start with a scheduled maintenance or diagnostic visit for a narrow equipment type or service zone. Put maintenance membership terms in writing: what visits are included, when they occur, and what happens when a repair or part is not included. Check the credentials your offered work requires.
Find the price floor
Separate diagnostic revenue, repair parts and labor, and install bids in your reports. For installs, add equipment, delivery, direct crew labor, any agreed disposal and paperwork time. For a maintenance plan, budget the actual technician hours you owe later, not just the revenue collected today.
Find your first customers
Fill shoulder-season slots with a specific appointment offer and a clear service area. Ask for equipment age and the customer's concern on intake, without asking them to touch anything. Follow paid repairs and replacements separately so a busy phone is not mistaken for a profitable week.
Keep delivery manageable
Protect capacity for seasonal spikes. Check supplier lead times before promising a replacement date. Track callbacks by equipment and job type; warranty labor and a second trip can change how much the original invoice was worth.
Worked example

Hypothetical inputs, not a quote or forecast. Contribution is not take-home profit. Subtract any overhead, taxes, advertising, and other expenses not included above.
A decision worth getting right
Common question.
Should I advertise installations or tune-ups first?
Lead with the service you can schedule and finish reliably. A tune-up offer can build a repeat calendar, but price the visit on its own merits rather than depending on every visit turning into a replacement.
Where Branch Up Works fits
Build around this work.
Branch Up Works could build equipment-specific landing pages, seasonal reminders, an estimate follow-up workflow and a dashboard separating maintenance, repair and installs.
For accepted operators, the funded plan can cover the agreed build and marketing in exchange for a share of attributed sales you collect. You stay the owner.
