Meta description: A practical comparison of HVAC field service software for small-to-mid shops, covering ServiceTitan, Housecall Pro, Jobber, FieldEdge, Workiz, Sensi Predict, and ChatGPT. Real-world advice from a Peoria contractor.

It was 97 degrees last July in Peoria, and my buddy Rick was having the kind of day that makes you want to sell the business and move to Alaska. Three-truck shop down in Morton. His dispatcher Linda was juggling four emergency AC calls with a dry-erase board and a cell phone that wouldn’t stop buzzing. His best tech Mike was sprawled in a crawlspace under a ranch house in East Peoria, flipping through a stained flat-rate pricing book from 2021 trying to quote a blower motor replacement. By the time Mike called the office for a price check, the homeowner had already texted Rick’s competitor and booked with them instead.

Rick lost the job. And this was after he was paying nearly $400 a month for field service software that was supposed to “streamline his operations.”

Rick didn’t need AI to replace Mike. He needed something to answer the damn phone while Mike was under that ranch house, and to price the job before the customer lost patience. Most of these tools aren’t built for that. They’re built for 50-truck operations in Dallas, not a 5-person crew trying to survive July in central Illinois.

I called shop owners in Bloomington and Springfield. I watched demos. I compared pricing. Here’s what actually gets used, and what collects dust.

The Real Problem

Missed calls. Bad quotes. Techs driving from Dunlap to Washington while another guy sits two blocks from the job. Paper invoices that disappear into truck dashboards. Most HVAC contractors lose a huge chunk of online leads because nobody answers fast enough, and when they do, the pricing is a guess. July and August? Chaos. January? You’re paying for software you barely touch.

You don’t need another database. You need something that routes your trucks, prices your jobs, and answers your phones when you’re elbow-deep in a condenser line.

ServiceTitan: The Mercedes Minivan

ServiceTitan starts at $398 a month for the Starter plan. The punchline: the AI features—dynamic pricing and smart dispatch—are locked behind the Pro plan at $998 a month. That’s a used service van payment.

The demo made it clear why people pay it. The AI dispatch cuts travel time by routing the closest tech instead of sending your guy across town when someone’s already around the corner. The dynamic pricing engine adjusts quotes based on season, market, and customer history, so you stop underbidding when demand is through the roof.

But if you’re a one- or two-person shop, this is a joke. Overkill. The learning curve is two to four weeks, and that’s two to four weeks where your office manager is questioning every life choice that led them to this job. At $998 a month, I’d rather put that toward a new service van or just keeping my techs paid during slow winters. ServiceTitan is built for medium-to-large shops with serious volume. Everyone else is buying horsepower they can’t use.

Housecall Pro: The Sweet Spot

Housecall Pro starts at $69 a month, but you need the Pro plan at $169 to get AI job costing, and the Plus plan at $329 for AI lead scoring. This is where small-to-mid-size shops should start.

The AI job costing flags jobs that’ll lose money before you burn gas and labor getting there. The lead scoring prioritizes “my AC just died and my house is 90 degrees” over “how much is a new unit?"—exactly what you want when your board is lit up in July.

The mobile app works offline. That matters when your tech is in a basement with no signal. But the AI is basic compared to ServiceTitan. No native inventory management, so you’re bolting on another tool. And customer support? Users report waiting 24-plus hours for a response. That’s an eternity when your dispatch board is melting down.

Jobber: Good for Small Shops

Jobber’s Core plan is $69 a month, but you need Connect at $129 to unlock the AI quote generator. Grow at $249 adds smart scheduling for up to 10 techs.

Here’s what works: your tech snaps a photo of a condenser, and the AI spits out a quote based on millions of past jobs. A shop owner in Bloomington—Marcus, runs six techs—told me it nails simple residential swaps about four out of five times. Complex commercial diagnostics? You’re still reviewing every line item.

The client portal lets customers approve quotes and pay online, which cuts down on the “I’ll mail you a check” nonsense. But there’s no built-in marketing automation, and the inventory tracking is weak. No barcode scanning. If you’re a solo operator or running up to 10 techs, it’s a good fit. Just don’t expect it to run your whole back office.

FieldEdge: The Maintenance Specialist

FieldEdge is for the maintenance-minded crowd. $199 a month to start, $399 for Professional with AI predictive maintenance.

This one is impressive if you’ve got patience. The AI predicts compressor failures, refrigerant leaks, and capacitor burnout weeks in advance. It hooks into sensors like Sensi and Ecobee. A guy I know in Springfield, runs about eight trucks, told me it boosted his maintenance contract renewals because the system nudges customers before their unit dies.

But it needs six-plus months of historical data to train. If you’re switching from paper or spreadsheets, you’re waiting half a year for the AI to get smart. The mobile app is also clunky on older Android phones, which half your techs probably have. And there’s no marketing or lead generation built in. It’s a specialist tool, not a generalist.

Workiz: The After-Hours Band-Aid

If you get buried in calls and can’t afford a night dispatcher, Workiz is the only tool here that answers your phone at 2 a.m. Starts at $99 a month. The AI voice assistant books jobs and auto-dispatches the nearest qualified tech.

It handles most simple after-hours calls without a human. That’s huge. It also sends customers real-time GPS tracking so they know when to let the dog out.

But the AI voice bot hits a wall fast. It can’t handle complex diagnostic questions. “My unit is making a grinding noise” is fine. “I have a dual-zone VRF system with a refrigerant leak” gets escalated to a human every time. It’s limited to English and Spanish, and there’s no inventory or accounting. Think of it as a really good phone-answering service that also does dispatch, not a full platform.

Sensi Predict: The Thermostat Spy

This isn’t software; it’s a smart thermostat with built-in AI diagnostics. $99 to $149 per unit, plus $15 a month per thermostat for monitoring. Install 10 units, and the contractor dashboard is free.

Emerson says it catches short-cycling, dirty filters, and low refrigerant before the customer notices. Fewer 10 p.m. emergency calls.

The catch? It only works with Sensi thermostats. No universal sensors. If the customer’s Wi-Fi goes out, you’re blind. And you still need a field service platform for scheduling. It’s an add-on, not a foundation.

ChatGPT Custom GPT: The $20 Cheat Sheet

For $20 a month, you can build a custom GPT trained on your pricing books, manuals, and troubleshooting guides.

Techs can ask, “What’s the R-22 replacement for a 3-ton Carrier?” and get an answer in seconds. You can generate estimate language and follow-up emails.

But it’s completely disconnected from your other tools. No integration. You copy and paste everything. And it makes stuff up on rare equipment. Imagine your tech trusting it for a heat exchanger diagnosis and ordering the wrong part. It’s a $20 pocket reference, not a dispatch system.

Head-to-Head

ServiceTitan has the most powerful AI, but you’re paying $998 a month to unlock it. Housecall Pro gives you the best balance at $329 a month for a 10-tech shop. Jobber is the cheapest entry point at $129 for AI quotes, but lighter on back-office tools.

Workiz beats everyone on phone answering, but lacks inventory, accounting, and complex scheduling. FieldEdge wins on predictive maintenance, but you need history and patience. Sensi Predict is in its own lane. And ChatGPT is the duct tape holding the whole operation together.

How to Choose Based on Your Actual Situation

Here’s how I’d break it down if I were running a shop in Peoria.

Solo to 2 techs: Start with Jobber Connect at $129/month. Use the AI quote generator to speed up bids, and pair it with a $20 ChatGPT subscription for quick technical lookups. Don’t buy ServiceTitan if you’re running three vans. You’ll bleed cash.

3 to 10 techs: Housecall Pro Plus at $329/month. The AI lead scoring and job costing will pay for themselves if they prevent even two bad truck rolls a month. That’s gas, labor, and opportunity cost you get back.

10+ techs or multi-location: ServiceTitan Pro at $998/month. It hurts, but at that scale, the dynamic pricing and route optimization save more than they cost. The Springfield guy I mentioned earlier said it added a couple extra calls per tech each week once they got past the learning curve.

Maintenance-heavy business: FieldEdge Professional at $399/month. If you’re trying to sell service agreements and reduce emergency calls, the predictive AI is your best friend. Just be patient during the training period.

After-hours call nightmare: Workiz Scale at $399/month. If you’re losing half your leads to voicemail, the AI voice assistant is cheaper than hiring a night dispatcher.

The Bottom Line: What I’d Actually Buy

If I had to pick one platform to run a small-to-mid HVAC business in 2026, I’d go with Housecall Pro Plus at $329 per month.

ServiceTitan is better on paper, but most shops aren’t big enough to justify the price. Jobber is cheaper, but the lack of inventory and marketing tools means you’ll outgrow it fast. Housecall Pro sits in the sweet spot. The AI job costing stops you from eating a loss on a bad bid. The lead scoring makes sure your best tech isn’t chasing tire-kickers while emergency calls go to voicemail. At $329, it’s not cheap, but it’s not “skip payroll” expensive either.

I’d pair it with a custom ChatGPT for $20 a month so my techs have instant answers in the field. And if I were pushing maintenance contracts hard, I’d add Sensi Predict thermostats to my installs so the diagnostics feed me recurring revenue without me lifting a finger.

No single tool fixes everything. But the right combination stops you from losing money on missed calls, bad quotes, and wasted truck rolls. For most contractors, that’s Housecall Pro Plus, a cheap AI chatbot, and a thermos of strong coffee for the summer rush.

Now go fix some air conditioners. It’s getting hot out there.
