The best estimating apps for HVAC contractors in 2026
Staxen is the best estimating app for HVAC contractors in 2026 at $59 a month, and the first job is free with no card. Describe the changeout in the attic by voice, and a priced, line-item proposal is ready to text for e-signature, deposit included. Because one app never fits every shop, we also rank ServiceTitan, Housecall Pro, Workiz, Jobber, and Contractor Foreman with verified September 2026 prices and honest downsides.
How this list was chosen
An HVAC estimate has a short shelf life: the homeowner with a dead condenser in July is getting three bids this week. So we weighted speed from site visit to signed proposal, then phone usability, e-signature, and deposit collection. Every pick except ServiceTitan starts under $150 a month, and each was built with a solo-to-small crew in mind rather than a 40-truck fleet. Prices were checked in September 2026, not copied from old roundups.
1. Staxen ($59 a month for Eddie the Estimator, $149 a month for all three AI employees. First job free, no card required.)
Best for: HVAC contractors who want the proposal signed while the urgency is high
Pros:
- Voice-drafted, priced line items you review instead of building from scratch
- Customer signs and pays the deposit from one text link, no app on their end
- Estimates are texted from a dedicated business number, so replies come back to you
- English and Spanish, on web, iOS, and Android
Cons:
- No dispatch board or GPS tracking, which a maintenance-agreement fleet will miss
- Newer product with a smaller template marketplace than the big field service platforms
2. ServiceTitan (Quote only; third parties report $245 to $500 per technician a month plus setup fees of $5,000 or more, as of September 2026)
Best for: HVAC companies running 10 plus techs with a call center
Pros:
- The deepest dispatch, call booking, and price book stack in the trade
- Good-better-best proposal presentation built in
Cons:
- 12-month contract and heavy onboarding cost
- Per-technician pricing gets expensive fast for small shops
3. Housecall Pro (Basic at $59 a month billed annually, $79 month to month, one user, as of September 2026)
Best for: One and two-truck HVAC shops focused on service calls
Pros:
- Solid scheduling, invoicing, and payment collection
- On-my-way texts and online booking customers like
Cons:
- QuickBooks sync and multiple users require higher tiers
- Proposal building is manual line-by-line entry
4. Workiz (Free Lite tier capped around 20 jobs a month; Standard at $225 a month for up to 5 users, as of September 2026)
Best for: Shops that want dispatch features cheaper than ServiceTitan
Pros:
- Free tier lets you evaluate before paying
- Built-in calls and texting on paid plans
Cons:

5. Jobber (Core from $29 a month billed annually, $49 month to month, as of September 2026)
Best for: Small HVAC crews that want simple quotes plus a schedule
Pros:
- Clean quoting with deposits and optional add-ons
- Well-reviewed mobile app for field crews
Cons:
- No HVAC-specific tooling like load calculations or equipment catalogs
- User limits per plan tier
6. Contractor Foreman (From $49 a month billed annually, with a price lock, as of September 2026)
Best for: HVAC contractors doing light commercial bid work
Pros:
- Bids, change orders, submittals, and daily logs at a low price
- Rate locks when you sign up
Cons:
- Cluttered interface with a real learning curve
- Better at project paperwork than fast field quoting
Count your techs before you shop. Under five, and your revenue leaks through slow proposals, not routing, so a $59 estimating tool like Staxen beats a $245 per tech platform you will not fully use. At ten techs with a dispatcher, ServiceTitan's cost starts paying for itself. Try the no-risk entries first: Workiz Lite is free and Staxen's first job is free with no card.
Frequently asked questions
What is the best estimating app for HVAC contractors in 2026?
Staxen is the best fit for HVAC shops under about five techs. You describe the system and scope by voice, Eddie the Estimator drafts priced line items, and the homeowner e-signs and pays a deposit from a text. It costs $59 a month and the first job is free. Larger dispatch-driven companies should evaluate ServiceTitan or Workiz.
Is there a genuinely free estimating app for HVAC work?
Workiz offers a free Lite plan, but it caps around 20 jobs a month, so treat it as an extended trial. Joist no longer has a free plan (it starts at $12 a month), and Invoice Simple's cheapest tier is $6.99 a month with a 3-invoice cap. Staxen gives you the first job free with no card and no time limit, which means you can run one real replacement quote through it before paying a dollar.
How much is Staxen for an HVAC business?
Staxen runs $59 per month per AI employee, or $149 per month for all three. Eddie the Estimator handles proposals, e-signature, and deposits, and Ivy adds invoicing with QuickBooks sync if you take the bundle. Month to month, cancel any time, and the first job is free with no card.
What should an HVAC replacement estimate include in 2026?
A residential changeout estimate should name the exact equipment (brand, tonnage, SEER2 rating), the refrigerant (new systems now ship with R-454B or R-32 after the 2025 transition), line set and electrical scope, permit and disposal fees, and warranty terms. A typical 3-ton full system replacement lands between $8,000 and $12,500 installed in most markets. Skipping a Manual J load calculation to save an hour is how systems get oversized and callbacks happen.
Do I need dispatch software or an estimating app?
They solve different problems. Dispatch software earns its cost when you have enough techs that routing and call booking is the daily headache, usually five or more. An estimating app earns its cost the first time a same-day proposal beats a competitor who mailed theirs on Thursday. Many small HVAC shops run an estimating tool now and add dispatch later.
