HVAC isn't one business — it's a service-call business and a maintenance-agreement business stapled together, both swinging with the weather. Here's how Tabsy fits the way the trade really operates.
Your service plans — spring AC tune-up, fall furnace check — are the closest thing HVAC has to recurring revenue. Tabsy stores each agreement as a recurring job tied to the customer and their equipment, so the spring and fall visits land on the schedule on their own and the membership invoices on its own cycle. No more pulling a binder of agreements every March and wondering who you forgot to call.
The first 95-degree week of summer is when six months of revenue tries to happen in ten days. The bottleneck is never the work — it's the desk. When the phone won't stop, estimates get scribbled on the back of a work order and never sent, and that's a lost job. Build the quote on site from your pricebook, text it for one-click approval before you leave the driveway, and turn it into an invoice the day the install is done.
A failed compressor or a cracked heat exchanger is a fork in the road: a $900 repair or a $7,000 system. The homeowner wants to decide while you're standing in the basement. With a saved pricebook you can put both options on one estimate — repair line items and a full-system replacement — and let them e-sign the one they want before the emotion of "my house is freezing" wears off. The equipment record on their profile means next time you already know the model, age, and history.
A maintenance tune-up and a 5-ton rooftop changeout are not the same call. Sending your newest tech to a refrigerant-charge problem burns a truck roll and a callback. Tabsy's scheduling lets you see the whole crew's day and assign the right person to the right job, with automatic customer reminders so the homeowner is actually home when the tech rolls up.
A note on compliance. System changeouts and new circuits for condensers usually need a mechanical or electrical permit, and EPA Section 608 certification governs anyone handling refrigerant — Tabsy isn't a permit or licensing tool, but keeping the signed estimate, equipment model numbers, and job photos on one customer record makes pulling a permit or backing up a warranty claim far less painful. Example, hypothetical: on a $7,200 furnace-and-coil replacement you might e-sign the contract and collect a deposit in the basement, attach the AHRI match and serial photos to the job, then invoice the balance the day the permit's signed off.
Unlike bloated enterprise software that takes months to learn, Tabsy is designed specifically for small to medium-sized HVAC businesses.
Run your whole HVAC operation — estimates, scheduling, invoicing, and payments — in one place.
