How Fieseros transforms HVAC operations

HVAC is a business defined by seasons. For six months of the year, work is steady — preventive maintenance visits, the occasional install, filter changes. Then a heatwave or cold snap hits, and suddenly you have 50 emergency calls before lunch. HVAC service management software that can't handle both modes — the steady recurring revenue engine and the seasonal surge — isn't really HVAC software. Fieseros is built for both, with scheduling and dispatch designed for the realities of the trade.

The recurring revenue side of HVAC is where strong businesses are built. A well-run HVAC company should have hundreds of preventive maintenance contracts — spring AC tune-ups, fall furnace inspections, quarterly commercial rooftop checks — that generate predictable income year-round and keep customers loyal. But managing those contracts in spreadsheets or paper files is a losing battle. Contracts get forgotten, customers don't get called, and a competitor swoops in with a friendly reminder. Fieseros automates the entire maintenance contract lifecycle: scheduling, SMS reminders, dispatch, invoicing, and renewal. You set it once, and the recurring revenue keeps flowing.

Equipment tracking is the second pillar of a strong HVAC operation. When a customer calls about "the AC in the upstairs bedroom that keeps tripping," you need to know exactly which unit that is — model, serial, install date, what was repaired last summer, whether it's still under warranty. Fieseros keeps a complete asset record for every piece of equipment at every customer site, tied to a single customer CRM so the full history is one click away. This isn't just operational efficiency — it's how you build trust. When a technician walks up to a unit already knowing its history, customers notice. And when it comes time to recommend a replacement, you have the data to back it up.

Finally, there's compliance — the part of HVAC that keeps business owners up at night. EPA 608 certification, gas furnace qualifications, manufacturer-specific training — each technician has different credentials. Track technician certifications and qualifications so dispatchers can assign the appropriate technician to each job. Fieseros stores each technician's certification documents in their profile and shows their skills on the dispatch board so you can match techs to jobs manually. Equipment service history is logged per asset, with photos and notes attached to every visit, so you have a complete record in any dispute. This is what air conditioning software should do: not just schedule jobs, but protect the business running them — and integrate with broader field service management tools as you grow.

Frequently asked questions

Everything HVAC business owners ask before switching to Fieseros.

How does Fieseros handle the summer and winter HVAC rush?

Seasonal demand is the defining challenge of an HVAC business. When the first heatwave or cold snap hits, call volume can spike dramatically overnight. Fieseros handles the surge in three ways: first, an emergency triage queue that prioritizes calls by urgency (no AC in 100°F with elderly residents gets priority). Second, dynamic dispatch that shows every available technician, their certifications, and live location so you can route the right tech to the right job fast. Third, automated Email, SMS, and Push notifications that keep customers informed — ETA, technician name, status updates — so they stop calling you for updates. Fieseros helps you automate customer communication so fewer opportunities are missed during peak periods.

Can I track preventive maintenance contracts in Fieseros?

Yes — preventive maintenance contracts are a core workflow in Fieseros. You define each contract once: customer, equipment, service frequency (spring tune-up, fall furnace check, bi-annual, quarterly), price, and renewal date. Fieseros then automatically schedules each visit, sends the customer an SMS reminder before the appointment, dispatches the technician, generates the invoice, and tracks the contract renewal date. When renewal time approaches, Fieseros alerts you to reach out and lock in another year. Fieseros automates the maintenance contract lifecycle: scheduling, reminders, dispatch, invoicing, and renewal tracking.

How does equipment service history work in HVAC software?

Every piece of HVAC equipment — central AC unit, furnace, heat pump, mini-split, commercial rooftop unit — gets an asset record in Fieseros. That record stores the model number, serial number, install date, warranty info, and complete service history: every repair, every tune-up, every part replaced, every photo taken. When a customer calls about "the AC in the upstairs bedroom," you can pull up that exact unit and see what was repaired last summer, what the tech noted, and whether it's still under warranty — before you even dispatch.

How does Fieseros show technician skills on the dispatch board?

Each technician in Fieseros has a profile where you can list their skills and store their certification documents — EPA 608, NATE, manufacturer-specific training, and more. When you're dispatching, Fieseros shows each available technician's skill tags right on the dispatch board so you can match the right tech to the right job yourself. You stay in control of who goes where — no automatic filtering, just the information you need at a glance.

Does Fieseros support after-hours and emergency pricing for HVAC services?

Fieseros supports emergency, weekend, evening, and holiday surcharges through pricing rules, so you can charge the right price for after-hours or urgent HVAC work. You can also apply a call-out fee, per-km travel fee, and minimum or maximum caps. No manual price lookups, no undercharging for after-hours work.

Can I automate filter change and tune-up reminders to customers?

Absolutely. Filter changes are the highest-leverage reminder an HVAC business can send — they keep equipment running efficiently, prevent expensive breakdowns, and generate goodwill (and often a tune-up visit). Fieseros sends automated SMS reminders at the interval you define for each piece of equipment — monthly for 1-inch filters, quarterly for 4-inch, annually for media filters. Customers tap to confirm they changed it themselves, or tap to schedule a service visit. Fieseros automates the reminder workflow so customers stay on top of filter changes and you stay top-of-mind for service work.
