Best Software for HVAC Companies (2026)

For residential HVAC companies under about 15 technicians, the default software picks in 2026 are Jobber and Housecall Pro, with FieldEdge for shops that live in QuickBooks and sell maintenance agreements. Solo operators and small crews that self-schedule can skip dispatch software and run quotes, invoices, and follow-up on RadiusOS at $19/month flat. ServiceTitan is the 20-plus-truck enterprise answer, and commercial mechanical contractors are a different market entirely, where ServiceTrade fits.

Here are seven tools, with pricing as of Q3 2026. Several HVAC vendors are quote-based with no public pricing; those figures are reported from third-party teardowns and marked as such. Confirm with the vendor before budgeting.

Sort yourself first

Residential or commercial? Residential service and install is Jobber, Housecall Pro, FieldEdge, and ServiceTitan territory. Commercial mechanical with maintenance contracts and inspections is ServiceTrade territory. Tools rarely cross that line well.

Do you dispatch daily? Multiple techs on a schedule board means you need real dispatch software. An owner-operator who self-schedules does not, and can spend a tenth as much.

Where does revenue leak? Missed calls, unquoted estimates, or quoted estimates that go silent are three different problems with three different fixes.

1. Jobber: the small-shop default

Pricing: solo plans from $29/month billed annually ($49 monthly); team plans from ~$169/month; extra users ~$29 each.
Best for: 1 to 15 tech residential crews that dispatch daily.

The easiest-to-learn dispatch platform with the cheapest real entry price: scheduling, quoting, invoicing, payments, and a client portal that homeowners actually use. HVAC-specific gaps worth knowing: job costing is gated to the ~$149/month Grow tier, reporting is thin, and there is no inventory management, which matters once you stock parts. The full comparison and alternatives guide cover the trade-offs.

2. Housecall Pro: automation-forward, add-ons add up

Pricing: from $59/month billed annually ($79 monthly) for 1 user; Essentials $149/month; MAX $299/month; proposals, GPS, and voice tools cost extra below MAX.
Best for: solo to 10-tech residential shops that want online booking and automated customer messaging.

The other default answer, with the fastest onboarding in the category, strong customer notifications, online booking, and consumer financing on invoices. Its AI answers website chats and analytics questions; voice call answering is a separately priced add-on. The recurring complaint is the add-on ladder turning a $59 plan into a $150-plus reality. Full breakdown in the comparison.

3. RadiusOS: quotes and follow-up without the dispatch tax

Pricing: free plan; Pro $19/month flat, not per user.
Best for: owner-operators and small crews that self-schedule replacements and service.

RadiusOS (that's us; grade accordingly) is for the HVAC shop whose leak is the estimate pipeline, not the schedule board. Walk & Talk captures the site visit as photos plus voice and writes the recap, Snap to Quote drafts the line items, the homeowner signs from their phone, and quiet quotes come back each morning with a follow-up email already drafted. Replacement quotes are exactly the kind of four-figure decision homeowners sit on for two weeks; the follow-up is where those close.

It has no dispatch board, GPS, inventory, flat-rate price book integrations, or QuickBooks sync. A shop rolling three trucks a day needs one of the platforms above; the ServiceTitan comparison maps the whole size ladder. See RadiusOS for HVAC for the fit.

4. FieldEdge: the QuickBooks and service-agreement pick

Pricing: quote-based; reported around $100/month per office user and $125/month per field tech, plus setup fees of $500 to $2,000. A 5-tech shop typically lands near $800 to $1,200/month. Confirm with the vendor.
Best for: 3 to 20 tech residential shops that live in QuickBooks and sell maintenance agreements.

FieldEdge's QuickBooks sync is consistently rated the deepest in the category, and its flat-rate pricing books plus service-agreement management are genuine differentiators for the maintenance-plan business model. The trade-offs: a dated interface, opaque quote-based pricing with add-on creep (inventory and advanced reporting cost extra), and less polish than newer rivals.

5. Workiz: dispatch with a built-in phone system

Pricing: free Lite plan for up to 2 users; paid plans roughly $187 to $270/month, confirm with the vendor.
Best for: 3 to 20 tech phone-heavy operations.

Native VoIP, call tracking, call recording, and two-way texting inside the dispatch platform, which matters for HVAC shops that book by phone. Complaints center on cost at small sizes and features gated to upper tiers. The free two-user tier makes it easy to evaluate honestly.

6. ServiceTitan: the enterprise graduation

Pricing: quote-only; estimated $125 to $398 per technician per month on annual contracts, plus onboarding commonly estimated at $5,000 to $15,000.
Best for: 20-plus-truck operations with a staffed call center.

The category heavyweight: call-center telephony with recorded and scored calls, dispatch optimization, payroll, inventory and purchase orders, memberships, and enterprise reporting. It earns its price at scale and punishes shops that buy it early; ServiceTitan itself says the platform is not optimized for companies with 3 or fewer techs. The alternatives guide covers the step-down options.

7. ServiceTrade: the commercial mechanical lane

Pricing: per-technician and quote-based; reported from about $89/tech/month billed annually, with office users free.
Best for: commercial mechanical contractors running maintenance agreements and inspections.

The rare platform actually built for commercial service: agreements, inspection workflows, deficiency-to-quote pipelines, and a customer portal with service history, with free office seats that make the pricing scale sensibly. It is the wrong tool for residential consumer work, and its listicle appearances are almost exclusively in commercial roundups, which is where it belongs.

The short version

Residential, dispatching daily: Jobber or Housecall Pro; Workiz if the phone is your front door.
QuickBooks-centric with maintenance plans: FieldEdge.
Solo or small crew, estimate follow-up is the leak: RadiusOS, free to start.
20-plus trucks with a call center: ServiceTitan.
Commercial mechanical: ServiceTrade.
