HVAC Software — Field Service, Estimating & Dispatch

Built for the HVAC service day

The four problems generic HVAC software ignores.

If you've ever tried to make Housecall Pro or Jobber behave like proper HVAC field service software, you'll recognize all four.

Maintenance contracts

Recurring jobs per unit — annual furnace check, quarterly filter swap, biannual chiller service. Set once, auto-generate forever.

Equipment history per unit

Every rooftop, every split, every chiller — its own service log, photos, parts list. Walk in already knowing what you did last quarter.

Multi-site dispatch (Pro)

Assign jobs to the right tech by skill, certification, proximity and current load. No more "who's nearest?" group chats.

Emergency callouts

Heatwave at 2pm, a no-cooling call lands. Add the job in 15 seconds, re-route the day, notify everyone affected on WhatsApp. No drama.

HVAC features

Six tools for the actual HVAC service day.

Recurring jobs & maintenance

Annual furnace inspection, quarterly filter swap, biannual chiller service — set the cadence once, Decker auto-generates jobs forever.

Quotes & estimates

Send maintenance contract quotes or one-off repair quotes in 60 seconds. Customer accepts on WhatsApp. Quote-to-invoice in one tap.

Customer CRM & equipment history

Every visit, every reading, every part — against the customer and the unit. Walk in knowing what you serviced last quarter.

Photo job notes with annotations

Photo the unit, mark the suspect part, attach to the job. Annotated proof for the customer and for the warranty.

One-tap WhatsApp invoicing & messaging

Maintenance reminders, ETA pings, invoice and payment nudges — generated and sent in one tap from your own WhatsApp. The channel customers actually read.

Time tracking per job

Hours on each unit, each service call. Build accurate quotes for next year's contract using last year's data.

Estimates & quotes

HVAC estimating software priced like an HVAC tech can afford it.

Quoting a 5-ton system replacement at a residential property and a chiller service contract at a 12-unit apartment complex are not the same job. Generic estimating software pretends they are. Decker's HVAC estimating software handles both, and it costs $19/month flat to do it.

Templates for the jobs you actually quote

Furnace replacement. AC condenser swap. Annual maintenance contract. Refrigerant leak repair. Each as a reusable template, loaded with the labour hours and material line items you've quoted before — so the next estimate takes 90 seconds, not 30 minutes at a desk after the visit.

Quote on site, on your phone

The customer is standing in the utility room with you. They want a number. Decker builds the quote on the phone, pulls in the customer's address, attaches photos of the old unit, and sends it via WhatsApp or PDF before you leave the driveway. They sign on their phone. You're scheduling the install on the way back to the van.

Markup baked in, not bolted on

Set your material markup once (40%? 60%? 100%? — your business, your margin). Every line item from your supplier price list lands in the estimate with markup applied automatically. No spreadsheet. No mental math. No bad quotes that lose you $400 because you forgot the markup at 6 PM.

Accept on WhatsApp, convert to invoice

Customer reads the estimate on WhatsApp. Taps "accept." Decker creates the job, schedules the install, generates the invoice on completion, pulls in any extras you added on-site. One workflow, end to end, in the channel your customers actually use.

Most HVAC estimating software is sold as a $79/user/month add-on to a $99/user/month platform. By the time you've got an estimate ready, you've paid for the privilege of building it. Decker's HVAC estimating software is included in the $19/month Solo plan and the $39/month Pro plan — not a separate module, not a separate fee, not a separate password.

And because Decker is built around the WhatsApp workflow, an estimate sent via Decker has a 60%+ acceptance rate inside 24 hours, based on early founding customer feedback. Compare to email quotes that sit in spam folders for three days.

Dispatch & routing

HVAC dispatch software for teams that don't have a full-time dispatcher.

ServiceTitan's dispatch board was built for HVAC companies running 15 trucks with a dedicated dispatcher in an office chair. Most HVAC service businesses aren't that. Decker's HVAC dispatch software is built for 1–10 technicians, dispatched by the owner from a phone, between their own jobs.

What HVAC dispatch software needs to do for a small team:

Show every tech's day on one screen — current job, next job, location, ETA. One glance from the parking lot of your own job.
Drag-to-reassign — drag a job from one tech to another and Decker automatically notifies the customer on WhatsApp ("your technician will be John instead — same time"). No phone tag.
Emergency callout in 15 seconds — a customer's AC failed at noon in July. You add the job, pick the closest available tech, pre-fill the customer's history, and the tech's phone vibrates with the new dispatch. Total time: under a minute.
Skill-based assignment — refrigerant work needs an EPA 608 certified tech. Decker filters available techs by certification when you assign. No more "wait, can John handle that?" mid-day.
Customer self-serve booking — Pro tier customer portal lets your regular maintenance contract customers book their own service window without ringing the office. Less phone tag, more service revenue.
Site-aware dispatch for commercial — multi-site HVAC contractors get a Sites view where every rooftop unit, every chiller, every air handler is tagged to a building. Dispatch the right tech to the right unit, not just the right address.

For a 4-technician HVAC service company, Decker Pro at $39/month flat replaces a typical $400–$600/month ServiceTitan or Housecall Pro setup — without losing dispatch capability. The flat rate matters when you're calculating the cost of running the business; the ability to dispatch fast matters every single weekday in summer.

Full HVAC FSM platform

HVAC field service management software, in one flat subscription.

"HVAC field service management software" is a category of products that traditionally cost $200 to $500 per user per month. Decker is that category, priced at $19/month for solo HVAC technicians and $39/month flat for HVAC contractor teams up to ten people — no per-user fees, no add-on modules, no enterprise tier upgrades waiting in the wings.

What "HVAC field service management" actually means for a working HVAC business — and how Decker handles each:

Customer relationship management — every customer, every property, every unit serviced, every invoice paid. The HVAC technician CRM that travels in your pocket.
Scheduling and dispatch — daily and weekly calendar view, skill-based assignment, drag-to-reschedule, WhatsApp customer ETAs.
Estimating and quoting — on-site estimates with materials, labour, markup applied automatically.
Mobile invoicing and payments — invoice from the truck, Stripe pay link to the customer, same-day deposits.
Recurring maintenance contracts — set a cadence (quarterly, biannual, annual), Decker auto-creates the job and pre-assigns it.
Equipment and machines inventory — every rooftop, every split, every chiller has its own service history, parts log, photos, downtime stats.
EPA 608 and refrigerant compliance — per-technician certification tracking, refrigerant logs per job, exportable audit trail for spot checks.
Reports that matter — monthly revenue, top customers, outstanding invoices, technician utilisation, contract renewal pipeline.

All of that is in the $39/month Pro plan. No "Compliance Pro Add-On." No "Reporting Pro Module." No "Sales Pro Upgrade." HVAC field service management software is supposed to manage the field service. Decker actually does that, for the price of two coffees a week.

The honest test: name a feature category in your current HVAC FSM platform (ServiceTitan, Jobber, Housecall Pro, FieldEdge) that you actually use weekly. Decker has it. Without the upsell pricing model.

Billing, accounting & inventory — without four subscriptions

HVAC billing software + HVAC accounting software + HVAC inventory software in one app.

Most HVAC businesses pay for HVAC billing software, HVAC accounting software, HVAC inventory software, and an HVAC CRM separately. Decker puts all four into the same app at one flat price.

HVAC billing software (invoicing & payments)

Build the invoice from the customer's rooftop — labour, refrigerant charge, parts, AC unit replaced, sales tax / VAT / GST applied automatically. Stripe pay link inside. Customer pays before you pack up. Same-day deposits to your bank. HVAC billing software the way it should always have worked. Targets: hvac billing software, hvac invoicing software, hvac proposal software.

HVAC accounting software + QuickBooks HVAC integration

Decker tracks income, expenses, refrigerant cost, parts markup, technician labour cost, mileage and tax owed across every job. Profit-and-loss per month, per customer, per unit serviced — one tap. Export to QuickBooks or Xero if your accountant insists. Most solo HVAC techs never need to. Targets: hvac accounting software, hvac bookkeeping software, quickbooks hvac software.

HVAC inventory software (per-unit equipment tracking)

Most "HVAC inventory software" tracks parts in a warehouse. Decker tracks something more useful: per-unit equipment inventory at each customer site. Every rooftop, split, chiller, mini-split — its own service history, photos, refrigerant logs, parts fitted, warranty status. The HVAC inventory that matters for service work. Targets: hvac inventory software, hvac inventory management software.

HVAC CRM + HVAC business management software

"HVAC CRM" usually means customer contact list with sales pipeline. Decker's HVAC CRM means customer + property + every unit + every service + every invoice + recurring contracts against one record. Plus the broader HVAC business management software layer — dispatch board, technician utilisation, monthly P&L, contract renewal pipeline. Targets: hvac crm, crm for hvac companies, hvac business management software, hvac management software, hvac business software.

For HVAC contractors & small businesses

HVAC contractor software for the businesses that grew out of one truck.

HVAC contractor software is supposed to manage the contractor side — multiple technicians, multiple sites, recurring maintenance contracts, equipment inventory, compliance. Most products in this category (ServiceTitan, FieldEdge) start at $400+/month with a multi-year commitment. Decker Pro is HVAC contractor software at $39/month flat for up to ten technicians.

HVAC service company software, HVAC service business software, HVAC service dispatching software — these terms all describe the same product type: software that runs the operational side of an HVAC service company. Decker is built for exactly that, designed phone-first because HVAC technicians don't sit at desks.

HVAC service software for small business + HVAC software for small businesses. If you're a 2–10 technician HVAC operation, you don't need enterprise software with an enterprise price tag. You need HVAC software for small businesses — phone-first, no per-user fee, no implementation consultant required, no 12-month contract minimum. Decker is exactly that.

HVAC field service software, finally priced for actual HVAC businesses.

HVAC field service software has historically been priced for the top of the market. ServiceTitan, Housecall Pro, Jobber, Workiz — all built primarily for HVAC contractor teams of 10+ trucks with a dispatcher and a back-office crew, all priced to match. If you're a one-truck HVAC technician or a small HVAC service business of 3–10 people, the per-user math has been brutal: $59–$79/month per seat is normal, advanced reporting modules cost extra, marketing automation costs extra, the "Pro" tier you actually need is double the headline price, and the bill quietly creeps past $300/month before you've finished your first quarter.

Decker is field service software for HVAC, priced the way a working HVAC business deserves. Solo at $19/month for one-truck HVAC techs and contractors. Pro at $39/month for HVAC service teams of 3–10 technicians. Both tiers flat. Both founding prices locked for life. No per-truck fees. No per-tech fees. No "we noticed you used a feature, so we upgraded your plan" emails. The headline price is the total price — full stop.

For the solo HVAC tech: HVAC scheduling software that works the way your day works. Drag jobs onto your week, auto-route, get a same-day pay-on-the-spot Stripe link to the customer's WhatsApp. Maintenance contracts as recurring jobs, customer history per address (every furnace serviced, every filter changed, every replacement quoted), and an automatic WhatsApp nudge when an invoice goes 3 or 7 days unpaid. The complete HVAC service software for small business, without a single line item on the bill you didn't expect.

For the HVAC contractor team: Decker Pro is HVAC field service management software priced like nothing else in the category. Sites give you a clean place to organize a multi-site commercial portfolio (offices, schools, restaurants, retail). Machines inventory means every rooftop, every split, every chiller, every furnace, every air handler has its own service log, parts list, photos and downtime stats. Technicians are first-class — assign by skill, certification, proximity and current load. Dispatch becomes a 30-second job, not a 30-minute group chat.

What sets Decker apart from other HVAC dispatch software: QR code public fault reporting. Print a QR sticker, stick it on the rooftop unit or the indoor air handler, walk away. The next time a facility manager or tenant notices a problem, they scan the code with their phone camera — no app, no account — and a ticket lands in your queue with the machine ID, the site, photos and a description. Auto-assigned to the right tech. WhatsApp confirmation back to whoever reported it. The single feature that pays for the whole subscription, used by HVAC contractors who service equipment across multiple sites.

Recurring maintenance contracts are a first-class workflow in Decker Pro. Set a cadence per machine type — annual furnace inspection, quarterly filter change, biannual chiller service, monthly cooling tower treatment — and Decker auto-generates jobs and auto-assigns the right tech. Custom checklists (per machine type, per job type) make sure every step gets done and every reading gets recorded. Stock requests let your techs flag the parts they need from the van; your office sees them instantly. Shipments track parts moving between sites or from supplier to van. The leaderboard keeps your team accountable. The activity log answers "who did what when?" without anyone having to write it down.

If you're comparing HVAC service company software, the math is direct: a comparable Housecall Pro setup runs ~$329/month real-world, a comparable Jobber setup runs ~$267/month real-world, and ServiceTitan starts north of that with a long contract attached. Decker Pro is $39/month, flat, locked for life as a founding customer. The savings — $200 to $400/month — are a tank of fuel, a set of gauges, or just margin you keep.

Whether you're a one-truck HVAC tech, a husband-and-wife HVAC service business, or a small HVAC contractor team servicing commercial equipment across multiple sites — Decker is the HVAC field service software priced like you matter. Reserve your founding spot below: Solo at $19/mo if you're solo, Pro at $39/mo for your team. Founding prices lock for life. Full refund if Decker doesn't ship in 90 days.

Compliance & record-keeping

Built for HVAC compliance reality: EPA 608, refrigerant logs, per-tech certifications.

If you've been an HVAC technician for more than a few years, you know two things about field service software: generic software doesn't understand HVAC compliance, and the software that does usually charges you twice as much because of it. Decker is built around what working HVAC contractors actually need to track — without making compliance a separate paid module.

EPA 608 certification tracking (per technician)

In the United States, anyone who maintains, services, repairs, or disposes of equipment that could release ozone-depleting refrigerants must hold a Section 608 certification (Type I, II, III, or Universal). Decker Pro lets you store each technician's EPA 608 certification type, certifying body, certificate number and expiry date inside their technician profile. When a certification approaches its 12-month-before-expiry mark, Decker reminds you on WhatsApp. When a job is being assigned that requires a specific type, Decker filters available techs by the certifications they actually hold. No more "oh, I thought he was Universal-certified" mid-job.

Refrigerant record-keeping (without a separate compliance app)

Every job that touches refrigerant — recovery, recharge, leak repair, system retrofit — gets a refrigerant-log entry in Decker: refrigerant type (R-410A, R-32, R-454B, R-22 legacy, etc.), pounds recovered, pounds added, leak rate if applicable, and the certifying technician. Records stay with the machine (not just the job), so when you sell the business or face an EPA spot check, the multi-year service history per unit is exportable as a clean PDF. Compliance becomes a by-product of doing your normal job entries, not an extra admin task.

State and provincial HVAC license tracking

State HVAC licensing varies wildly — California's C-20, Florida's CMC, Texas's TACL, the provincial Red Seal endorsements in Canada, Gas Safe registration in the UK. Decker stores your business license number and each technician's individual license (where applicable), with expiry alerts at 60-day and 14-day windows. License numbers can be auto-pulled into your customer-facing invoices and quotes when required by local regulations — a small detail that prevents real headaches with state contractor boards.

Why this matters more than feature-counting

Most "field service software" platforms treat HVAC as a tagged customer type and call it a day. Decker treats HVAC as a first-class workflow — refrigerant types, certification tracking, multi-site machine inventory, and recurring maintenance cadence are core, not bolted on. The reason this is in the $39/month Pro tier and not a separate $99/month "Compliance Pro" add-on is simple: HVAC contractors deserve to keep their margin, not hand it back to their software vendor every month.
