Best apps for an HVAC business in 2026

HVAC work comes in waves. The first hot week of summer and the first cold night of fall bring every no-cool and no-heat call at once, and in between you live on tune-ups, maintenance plans and the occasional system replacement. Good HVAC software has to cope with both: fast dispatch and invoicing on the busy days, and a reliable way to bring every maintenance customer back twice a year on the quiet ones.

Replacement jobs add another need. A homeowner choosing between a repair and a new system wants options on paper, often with financing, and the tech wants a price book so two techs quote the same job the same way. ServiceTitan, FieldEdge and Profit Rhino all list a pricebook or flat-rate pricing for exactly that.

This page compares six apps, including Workeey, which we make, using each company's own pricing and product pages read in November 2026. If you are mainly looking for the best invoice app for HVAC contractors, the invoicing row in the table is the place to start.

Housecall Pro

Best fit: a residential HVAC company with one to five technicians that wants booking, dispatch and invoicing in one app.

Housecall Pro's Basic plan includes online booking, scheduling and dispatching, quotes, and invoices with payments. Essentials adds route planning, flat-rate pricing, checklists for repeatable tune-ups, and QuickBooks Online sync. Consumer financing is listed too, which helps when a homeowner is looking at a full system replacement.

Pricing: Basic is $59 a month billed annually or $79 month to month, for one user; Essentials is $149 a month billed annually or $189 monthly, with five users included. No free plan; a 14-day trial without a card. iPhone and Android apps.

Who should look elsewhere: a single tech who does not need dispatching and wants to keep costs low.

ServiceTitan

Best fit: an established HVAC company with a call center, several trucks and a sales process for replacements.

ServiceTitan's pricing page lists dispatching, scheduling and call booking, invoicing, a pricebook, mobile estimates, memberships for maintenance customers, payroll, commission tracking and advanced reporting, along with a field mobile app for technicians.

There are three packages: Starter, Essentials and The Works. In the page text all three show the same feature list, and which package carries which feature is shown only in graphics, so ask on the demo call.

Pricing: per-technician pricing; every package says Request Pricing, so there are no public figures.

Who should look elsewhere: an owner-operator who wants a published price; ServiceTitan quotes per technician.

FieldEdge

Best fit: an HVAC service company that sells maintenance agreements and wants its techs to invoice and take payment at the equipment.

FieldEdge's HVAC software makes full service histories, equipment details, agreements and billing information available from anywhere. Techs complete invoices on site, email them straight to the customer and collect payment there. Flat-rate tools keep pricing consistent, QuickBooks syncs automatically, and its marketing tools are aimed at selling service agreements.

The Select plan includes dispatching, booking and scheduling, basic agreements and quotes, and a pricebook with flat-rate pricing. Premier adds quotes with several options, useful for repair-or-replace conversations, and more mobile app licenses.

Pricing: Select, Premier and Elite all say Request Pricing. The FAQ states that FieldEdge does not offer a free trial.

Who should look elsewhere: a contractor who wants to sign up today and see a price first.

Profit Rhino

Best fit: an HVAC company that already has job software but wants a proper flat-rate price book.

Profit Rhino's SmartPrice is a digital flat-rate price book and mobile sales tool for HVAC, plumbing and electrical work. Parts and pricing are updated quarterly, the tech presents options to the homeowner through the mobile sales tool, and its products list includes invoice and payments and a QuickBooks export.

Profit Rhino says success coaching and implementation are required, so plan for a setup period before the first flat-rate quote.

Pricing: SmartPrice Starter is $39 a month per tech, Plus $49 and Pro $59.

Who should look elsewhere: a tech who prices by the hour and does not want a price book.

Jobber

Best fit: an owner-operator HVAC tech or a small crew that wants customers to book tune-ups online.

Jobber's Core plan includes online booking, scheduling, quotes, invoices with online payments and a client hub, which works well for seasonal maintenance where customers pick their own slot. Automated reminders, quote and invoice follow-ups and QuickBooks Online sync arrive on Connect, from $99 a month billed annually.

It is a general field service app, so flat-rate price books and maintenance agreements are not on its pricing page.

Pricing: Core is $29 a month billed annually, $39 with a one-year commitment or $49 with none; extra users cost $29 a month each. No free plan; a 14-day trial without a card.

Who should look elsewhere: a shop that wants flat-rate pricing built in.

Workeey

Best fit: a one-truck HVAC technician who wants invoicing, quotes and a maintenance calendar on the phone, starting free.

Workeey's free plan comes with no card and no end date. You get unlimited invoicing, 23 quick estimates a month, and 10 payment reminder texts a month that you switch on per invoice. Save your service call, diagnostic, capacitor, contactor and refrigerant charges once with your own prices, and repair quotes come together in a few taps. The quote PDF is shared from your phone, a deposit percent can print on it, and after the homeowner agrees, one tap turns it into the invoice.

Invoices are emailed with a pay link for card, Apple Pay, Google Pay or US bank transfer through your own Stripe account, with a small processing fee. In a crawlspace with no signal the invoice is saved, and you email it when you are back in range. Connect your bank and matching payments mark invoices paid. For maintenance customers, a repeating job fills in the next 12 visits, and a day of tune-ups can be put in the best order for the first 11 stops. There is an assistant you can type or talk to. On Pro you add Google Calendar and QuickBooks sync and 30 texts a month; Premium gives unlimited texts.

It has no flat-rate price book like Profit Rhino's or FieldEdge's, no maintenance agreements or memberships, no financing, no dispatching or technician accounts, and no card reader or tap to pay. Deposits are not collected through the app, and the homeowner cannot accept the quote inside Workeey; they tell you yes. Workeey is built for the phone: the Android app is on Google Play, it runs in any phone's browser, and a desktop version is coming soon.

Pricing: free; Pro $5 a month; Premium $19 a month.

Who should look elsewhere: an HVAC company dispatching several technicians, or one that sells memberships and quotes from a flat-rate price book.

How to choose an app for an HVAC business

Count your trucks first. One tech needs fast quotes, fast invoices and a calendar; three to five techs need dispatching; a company with a call center and a replacement sales team is in ServiceTitan or FieldEdge territory. Paying for dispatch you do not use is an easy way to overspend.

Decide how you price. If you charge time and materials, any app that saves your parts and rates will do. If you want every tech to quote the same price for the same repair, you want a flat-rate price book. How to price a job explains the costs that belong in the number, and our guide to the service call fee covers what to charge just to show up.

Plan for maintenance. Tune-up customers are an HVAC company's steadiest income, so check how each app brings them back: memberships, agreements, or at least repeating jobs on the calendar.

Then check invoicing on the worst day of the year. On a 100-degree Saturday you want to finish the invoice and take payment before you leave the driveway. Try that on your own phone before you commit. For other trades, see the best apps for tradespeople.
