HVAC Canvassing Software in 2027: 5 Picks Compared

Key Takeaways

HVAC canvassing software is a phone app and back-office layer that assigns door-to-door territories, plans routes, logs every door knocked, and hands interested homeowners to a CRM or job queue.

TL;DR: Choose by how a lead leaves the door, not by the logo. Three of the five tools here publish a per-user price you can budget today, one publishes a flat monthly tier with a household cap, and one asks for a quote before it shows any number.

• Start with the category decision: a canvassing app is a different purchase from a full field service platform, and all five tools here lead with canvassing.

• Only Knockio's Growth and Organize plans list estimates and invoices (Growth also lists work orders and payments) on the pricing page, so check it first if you need billing in the same app.

• Ecanvasser's Core plan is $99 a month for unlimited users, but live rep tracking is a separate $99 add-on, which changes the math at four reps.

• Spotio publishes no price and offers no free trial, so expect a sales call before you have a number.

• Get every price in writing with its billing period, because the vendor pages disagree in places and two of them do not say whether a figure is monthly or annual.

How we evaluated these tools

This is an informed buyer's guide built from public information. We read each vendor's own pricing and feature pages, opened an independent pricing aggregator, checked a federal consumer rule page, and read trade and vendor articles that we label as vendor-owned. We did not run trials, interview customers, or survey contractors, so nothing here is a measured result. We also did not produce a composite score, because several vendors publish too little for a fair number.

The first two rows come first because they decide whether reps use the app every day and whether the monthly bill still makes sense at four or more reps. The rows are unweighted and the order is our judgment, so reorder them if your team's priorities differ.

Pricing: what each vendor publishes

Pricing checked November 13, 2026. Figures come from each vendor's own pricing page unless a sentence names a different source.

Team plan: $59 per user per month according to SalesRabbit (2026). That page lists the Team plan as billed monthly and includes advanced canvassing, plan routes, and rep location tracking. The Pro tier appears as $75 and $49 side by side, and the page does not say which figure applies to monthly billing and which to annual. A third-party listing, according to Toolradar (2026), shows Pro at $75 per user per month, billed monthly, with prices last confirmed November 7, 2026. Enterprise is quote-based.

The Starter plan on RepCard is $24 per user per month and the Pro plan is $49 per user per month, according to RepCard (2026). Canvassing tools and API access sit in Pro, not Starter, so a team that needs door-level maps should budget at the Pro price. The page shows a yearly and monthly toggle with a "Save 17%" label but does not say which billing period the figures reflect. Enterprise is custom.

Spotio does not publish a number. Its pricing page describes user-based, quote-based pricing for its B2B, B2C, and Custom plans and says no free trial is offered, though pilot programs can be arranged for qualified prospects, according to Spotio (2026). The same page says a dedicated customer success manager is included for 25 or more licenses.

Two cautions apply. The Ecanvasser page shows "$234 billed monthly" under both paid plans and a calculator that returns $299 and $1,299 for recommended database sizes, so get a written number that names one plan and one household count. The RepCard and SalesRabbit pages leave billing periods unclear in places, so we show the figures as listed rather than converting them.

Cost by team size

Prospect seat: $25 per user per month for 1–4 users according to Knockio (2026). The page lists $20 per user for five or more users, bills monthly with no contract, and charges 15 cents per pre-knocked address. It does not say whether the address fee is one-time or recurring, so ask before you budget a full territory.

The Core plan on Ecanvasser is $99 a month for unlimited users, according to Ecanvasser (2026). That plan caps the database at 50,000 households and lists real-time field tracking as a separate $99 monthly add-on. The Pro plan at $599 a month raises the cap to 1,000,000 households, and the public API is a $99 add-on on Pro.

These are base-plan seat costs per month, before add-ons and address or lead data. Knockio's figures use $25 per user up to four users and $20 from five. Ecanvasser's figure covers unlimited users but excludes the $99 tracking add-on, which would make it $198 a month at every team size in this table. RepCard's figures assume the Pro price applies, and SalesRabbit's figures use the Team plan, which does not include Pro features such as API access.

Worked example: four reps on one ZIP code

Take a four-rep replacement crew working one ZIP code with 10,000 pre-knocked addresses over a six-month season. On Knockio's Prospect plan, four seats at $25 each cost $100 a month, or $600 over six months, and we leave out the optional pre-knocked address data (15 cents per address, which would add $1,500 if it is a one-time fee) so the comparison stays like for like, since other vendors' lead-data add-ons are not priced here. On Ecanvasser's Core plan, unlimited users cost $99 a month and real-time tracking adds $99, for $198 a month or $1,188 over six months, provided the ZIP code's door list stays under the 50,000-household cap. The same four seats on RepCard's Pro plan run $196 a month, or $1,176 over six months, and SalesRabbit's Team plan runs $236 a month, or $1,416. Before add-ons, Ecanvasser Core is lowest at $594 and Knockio close behind at $600. Once you add the live tracking that Knockio's Prospect plan already includes, Ecanvasser rises to $1,188, and SalesRabbit's Team plan is highest at $1,416. Seat price is only part of the cost; leads that stall after the knock are covered in the section on where leads leak below, where status changes appear as lead_status_history_item records.

Feature matrix

"Not stated" means the vendor page we read does not say. It does not mean the feature is absent, so ask the vendor before you rule a tool out.

Five tools: where each one fits and where it stops

SalesRabbit

• Best fit: a team that wants a door-to-door app with a free one-user tier to start, then a Team plan for maps, plan routes, and rep location tracking. The Team plan also includes Digital Sales Tools and Amplify Analytics on the pricing page.

• Limitations: the Pro price appears twice without a billing basis, and implementation packages are required with no prices shown. Enterprise adds SSO and a custom SLA. Add-ons such as DataGrid AI and Digital Contracts are separate line items.

• Implementation: start on Team if you need maps and routes only. Move to Pro when you need API and integrations or custom fields, and budget for an implementation package before go-live.

• Evidence: SalesRabbit pricing page and SalesRabbit developer docs.

RepCard

• Best fit: a sales team that also wants referral, review, and training tools in the same app. RepCard's HVAC page describes seasonal door-to-door pushes and multi-crew management, and it says its canvassing maps assign territories and route reps.

• Limitations: Starter has no canvassing tools, so Pro at $49 per user is the realistic entry for door work. The pricing page does not say whether its prices are monthly or annual. The HVAC page's percentage claims are the vendor's own and unsourced, so we did not rely on them.

• Implementation: budget for Pro, and confirm in writing whether the ServiceTitan or FieldRoutes integration that the HVAC page mentions in a blog teaser is available on your plan.

• Evidence: RepCard pricing page and RepCard HVAC page.

Spotio

• Best fit: field sales teams that want route planning on the B2B plan, offline access on the B2C plan, and implementation support on all plans.

• Limitations: no published price and no free trial. The page does not mention an API, and tailored integrations appear only on the Custom plan. Location tracking and offline access are described under different plans, so confirm which one your crew would get.

• Implementation: ask for a pilot, which the page says can be arranged for qualified prospects, and get a written quote that lists each add-on.

• Evidence: Spotio pricing page.

Knockio

• Best fit: small HVAC teams with one to four reps who want low per-user pricing, route planning, real-time rep tracking, and digital contracts on the Prospect plan. Teams that also need invoices and payments in one app should look at Growth.

• Limitations: Prospect has no estimates or invoices. The address fee adds to cost, and the page does not say whether it recurs. Scale is quote-only for 100 or more users, and engage phone numbers are an optional add-on at $15 per number per month.

• Implementation: Prospect and Organize both list Zapier and FlowChef integrations. Ask for the trigger and field list before you build anything, because the pricing page does not publish them.

• Evidence: Knockio pricing page.

Ecanvasser

• Best fit: a team of four or more reps that wants unlimited users on one flat plan. The page lists unlimited users and unlimited teams on all paid plans, plus territory mapping, route planning, appointment scheduling, and offline canvassing on Core.

• Limitations: Core's 50,000-household cap, the $99 tracking add-on, the API add-on on Pro, and conflicting figures on the page. Enterprise requires a 12-month minimum term. The page says data is deleted within 30 days of a cancellation request, so export before you cancel.

• Implementation: use the 7-day free trial, which the page says is available once per customer, to load one territory and count households against the cap.

• Evidence: Ecanvasser pricing page.

When NOT to use US Tech Automations: skip a custom workflow if a tool already covers your gap. If you run one or two reps, the Knockio Prospect plan with its Zapier link is simpler to start than any custom design. If your only gap is text follow-up after the knock, a dedicated messaging tool may fit better. If nobody on your team will review an exception queue each morning, a configured workflow adds a failure point rather than removing one.

Why owners are looking at door-to-door again

Door-to-door HVAC selling is an old channel that fell out of favor. A column in Contracting Business argued that canvassing could return, noting that few owners canvass themselves and recommending that owners hire salespeople to canvass and hold them accountable, according to Contracting Business (2022). The column is several years old, so read its prediction as opinion, not data.

ServiceTitan's guide, published December 11, 2025, lists the upside: reps create their own leads, learn to handle objections, and do not need a large marketing budget. It also lists the costs: reps hear objections often, canvassing is time-intensive, and the channel is hard to scale without tracking, routing, and follow-up tools, according to ServiceTitan (2025). ServiceTitan sells field service software, so its framing favors a process layer, and you should weigh it that way.

Where leads leak after the door

The gap that costs the most is usually between the knock and the callback. A rep logs an interested homeowner on a phone, and the lead sits in an app that does not talk to scheduling.

A proposed, configurable workflow from US Tech Automations would start when a rep changes a door's status to interested in the canvassing app. The action reads that lead's status history through the vendor's API, creates or updates the CRM contact, and opens a callback task for the sales manager. On SalesRabbit, the API returns each status change as a lead_status_history_item record, according to SalesRabbit developer docs (2026), so the workflow could push those changes into a CRM queue, and a manager would still review every replacement quote before a crew is sent. The output is one queue showing the address, the equipment age the rep recorded in a custom field, and a callback window the manager sets. Prerequisites are an API key on a plan that includes API access (Pro on SalesRabbit, Pro on RepCard, and an add-on to Pro on Ecanvasser), a field map signed off by the operations lead, and a named owner for the exception queue. Human review points are a manager approving any replacement quote before a crew is booked, and someone confirming local solicitation rules before any follow-up visit.

US Tech Automations could configure a second proposed design for Knockio users. Knockio's pricing page lists Zapier and FlowChef integrations on the Prospect and Organize plans, so the design would start from one of those connections. The page does not publish trigger names or contact fields, so the first step is a field inventory with the vendor. The action would merge duplicate contacts across crews and suspend follow-up on any do-not-contact status, and the output is a daily exception report that the operations lead reviews each morning. Prerequisites are the Zapier plan, the field inventory, and an approval step before any automated text or call goes out.

If your gap is text follow-up after the knock rather than the callback, our SMS software guide for HVAC companies covers that channel.

The legal check before you knock

Federal rules add a cancellation right for some in-home sales, and state and city rules often go further. Cooling-off threshold: $25 for sales made at the buyer's home according to 16 CFR Part 429 (2026). The rule defines a door-to-door sale as one with a purchase price of $25 or more made at the buyer's residence, or $130 or more at other locations, and requires the seller to tell the buyer they may cancel at any time before midnight of the third business day after the sale. Build that disclosure into the contract template in your canvassing app, and confirm the app timestamps each sale so you can prove when it happened.

Check your state, county, and city for solicitation hours, permit requirements, and no-soliciting restrictions before the first crew goes out. The field-service guide cited above notes that some cities have strict soliciting rules and others require permits.

DIY versus a stitched-together automation

Some buyers build this in Zapier, Make, or n8n, or hire a developer to write it in-house. Those tools can support run histories, retries, error branches, and audit evidence when they are configured that way. The buyer still has to design and own observability, idempotency (so a retried webhook does not create a duplicate contact), escalation, access controls, and maintenance when a vendor changes its API. A proposed US Tech Automations design could configure those pieces differently, with run history and retry rules set up at the start, an escalation path to a named manager, and access limits by role. The prerequisites are the same either way: API access on the plan you choose, a field map, and a named owner. Nothing in this section describes a live deployment.

Who this is for

Who this is for: an owner or operations lead at a small HVAC business that already sends reps door to door, or plans to, and needs a phone app before a full field service suite.

Red flags: you need a written price before any sales call, and Spotio's quote-only model will slow you down. You want scheduling, dispatch, and invoicing in one system, which a canvassing app will not give you on its own. No one on your team will own the exception queue after go-live.

Decision checklist

• Count the reps who will knock in your busiest month, and price that number on each vendor's page.

• Confirm whether tracking, offline use, and API access are included or are add-ons.

• Ask for the household or lead cap in writing.

• Confirm the billing period (monthly or annual) for every figure you plan to budget.

• Ask for the data-export and deletion policy before you sign.

• Check local solicitation rules before the first knock.

Common mistakes

• Comparing headline prices and skipping add-ons, such as Ecanvasser's $99 tracking add-on.

• Assuming RepCard's Starter tier includes door-level canvassing. The page lists canvassing tools under Pro.

• Buying a quote-only tool without a pilot or a written price.

• Connecting a CRM before a field map exists, which turns duplicate contacts into a cleanup project.

• Reading a Pro price as monthly when the page does not say so.

Frequently asked questions

Do I need canvassing software if only one person knocks doors?

Not always, because SalesRabbit offers a free Lite tier for one user with limited features, which can be enough to test the workflow.

Which plan with canvassing has the lowest published per-user price?

Among plans that include canvassing features, Knockio's Prospect plan has the lowest published per-user price, at $25 for one to four users and $20 for five or more. RepCard's Starter plan is cheaper at $24, but it does not list canvassing tools.

Which tools list estimates or invoicing?

On the pricing pages we read, only Knockio's Growth and Organize plans list estimates and invoices, and Growth also lists work orders and payments.

Is there a free trial?

Ecanvasser offers a 7-day free trial once per customer, and Spotio offers none. SalesRabbit's free Lite tier covers one user with limited features, and RepCard's free plan is for personal use.

Can I get Spotio's price without a sales call?

No, not from its pricing page, which publishes no figures and says pricing is quote-based.

Choosing a shortlist before the season

Start with three numbers: the reps who will knock in your busiest month, the households in your territory, and the number of seats that need invoicing in the same app. Then ask each shortlisted vendor for a written price for that exact setup, including add-ons, the billing period, and the data-export terms.
