The 5 Types of HVAC Estimating Software
Sort the options by how they get quantities before you compare features. Product details and prices below are from each company's own website as of October 2026.
| Type | How it gets quantities | Built for | Examples (from their sites) | Published price |
|---|---|---|---|---|
| Duct and sheet metal estimating | Takeoff of rectangular, round and oval ductwork, sheet metal and HVAC equipment from plans | Commercial and industrial sheet metal contractors bidding from drawings | FastDUCT: "designed to meet the needs of commercial and industrial sheet metal contractors." Wendes: "Built for Commercial HVAC Sheet Metal Contractors" | FastDUCT: $4,995 one time or $250 a month (first application). Wendes: no price on its HVAC page |
| General plan takeoff | Trace and count on digital plans, then apply assemblies for material, labor and waste | Estimators with a plan set who want one takeoff tool across trades | PlanSwift: "Quickly trace linear takeoff for A/C line sets" and measure "ductwork, piping, equipment" | $2,000 a year (Essential) or $3,000 a year (Core), per seat |
| Load calc and design suites | Load calculation and duct design drive a parts list and a customer proposal | Contractors who size and design systems in-house | Wrightsoft Right-Suite Universal: load, duct design, parts list and proposal in one Windows program | Residential Package $900 a year; Right-J Mobile $150 a year |
| Field service platforms | Techs pick tasks from a flat-rate pricebook; office handles dispatch and billing | Service and replacement shops running several trucks | ServiceTitan: pricebooks and Good-Better-Best presentations on the mobile app | Not listed; pricing through a demo |
| AI estimators built from a site visit | AI drafts line items from photos, a voice walkthrough, notes and measurements | Residential replacement, add-on and remodel work bid from a walkthrough | EstimationPro (details below) | 3 estimates free, then $79 or $149 a month |
FastDUCT's purchase price includes the first year of maintenance; after that it lists $1,250 a year for the first application. PlanSwift offers a 14-day free trial with no card. Wendes shows no price on its HVAC page, and ServiceTitan's flat-rate page sends you to a demo for pricing. Price tracks the type: the takeoff tools run $2,000 a year or more per seat (PlanSwift) or $4,995 up front (FastDUCT), which makes sense if you bid from plan sets every week.
7 Questions to Ask Before You Pay for an HVAC Estimating Tool
Run every option through these before a demo call. A tool that fails the first question is the wrong type, no matter how good the rest is.
-
1. Where do your quantities come from?
Commercial duct work bid off drawings needs takeoff. A residential changeout bid from a walkthrough does not, and a takeoff tool will sit idle. Pick the type before you compare features.
-
2. Who does the load calc?
If you size equipment in-house and your inspector wants the calc, you need a load tool whatever else you buy. Some suites tie the load straight into the proposal; most estimating tools do not run one.
-
3. Flat rate, or priced job by job?
Service calls fit a pricebook. Replacements and installs swing with equipment, access and duct condition. Make sure the tool handles the work that makes up most of your revenue.
-
4. Where do equipment prices come from?
Your distributor quote, a built-in database or regional averages. Equipment is the biggest number on a changeout bid, so you need to override it with your real cost on every job.
-
5. Can you show more than one option?
Homeowners replacing a system often want to compare efficiency levels. Check that you can present tiers side by side without building three separate estimates.
-
6. What happens after you send it?
Follow-up, e-signature, deposits and payments. Some tools stop at the estimate; some carry the job through to getting paid.
-
7. What does it really cost?
Monthly or annual price, per-user or per-estimate limits, setup and training time. Some, like ServiceTitan, send you to a demo for pricing, so get the number in writing.
What a Residential HVAC Estimate Has to Include
Whatever software you use, check the output against this list before it goes to the customer. Anything missing is either free work or a change-order argument later.
- Equipment: condenser or heat pump, coil, furnace or air handler, with model numbers, size and efficiency rating so the customer can compare bids line for line.
- Removal: taking out the old equipment, refrigerant recovery and haul-away.
- Line set: reuse or replace. Write which one you priced, and check the new equipment's installation instructions before you assume reuse.
- Electrical: disconnect, whip and circuit for the outdoor unit. Say whether the existing circuit is reused or a new one is included, and who pulls that permit.
- Pad, drain and venting: equipment pad or wall bracket, condensate drain or pump, and furnace venting and gas connection.
- Ductwork: plenum and transitions to fit the new equipment, plus any new runs, sealing or insulation, priced by the linear foot.
- Controls: thermostat, and zoning if the job has it.
- Permit and inspection: its own line. Fee schedules vary by jurisdiction.
- Exclusions and allowances: what is not in the price, and how you handle what you find in the attic or crawlspace.
Equipment sizing, venting, clearances and duct requirements depend on the code your jurisdiction adopted and the manufacturer's instructions. Check your local code before you price them.
Worked Example: 3-Ton AC and Furnace Changeout
A 1,800 sq ft house with a worn-out 3-ton AC and gas furnace. Your load calc confirms 3 tons. The walkthrough notes: the existing line set and circuit can be reused, two trunk joints in the crawlspace leak, the back bedroom runs warm and needs its own supply run, and the exposed trunk has no insulation. Here is the bid at typical installed prices (labor, material, overhead and profit in each unit price).
| Line item | Qty | Unit price | Total |
|---|---|---|---|
| Replace 3-ton split AC and gas furnace: remove old equipment, set new condenser, coil and furnace, all labor | 1 job | $8,000 | $8,000 |
| Smart thermostat, installed | 1 each | $300 | $300 |
| Seal leaking trunk joints (mastic and foil tape) | 1 job | $450 | $450 |
| New supply run to the back bedroom | 25 LF | $30 | $750 |
| Insulation wrap on exposed trunk in the crawlspace | 40 LF | $4 | $160 |
| Mechanical permit and inspection | 1 permit | $200 | $200 |
| Total | $9,860 | ||
Each unit price is the typical figure in our pricing reference, which puts a full AC and furnace replacement at $5,500 to $12,000, a smart thermostat at $200 to $450, minor duct repair and sealing at $200 to $700, new ductwork at $18 to $55 per linear foot, duct insulation wrap at $2 to $6 per linear foot and a mechanical permit at $80 to $450.
Check the big line against your real costs. The $8,000 has to cover the condenser, coil and furnace, the crew's day, materials, overhead and profit. The reference puts a 2 to 5 ton condensing unit alone at $900 to $3,500, equipment only. Say your changeout takes a two-person crew one 10-hour day (plug in your own crew and hours). At a $100 billed rate (our reference range is $75 to $150 an hour), that is 20 hours, or $2,000 of labor. Add your distributor's quote for all three pieces of equipment to that. If what is left can't carry your overhead and profit, raise the line before the bid goes out. For a full labor-hour build-up on this kind of job, see how to price an HVAC job.
Write the assumptions. This bid reuses the line set and the outdoor circuit. If the new equipment's instructions or your inspection rule that out, a new line set or circuit is its own line, priced before you start, not a surprise after.
Prices vary by region. These are national ranges for 2026. Use your own labor rate and get local distributor quotes before you commit to a number.
Where Residential HVAC Bids Lose Money
Pricing equipment from last month's numbers
Equipment is the biggest line on a changeout, and EPA's 2025 fact sheet describes shortages and price spikes on R-454B during the refrigerant transition. Pull a current distributor quote for the exact models before you send the bid, and set an expiration date on the estimate.
No room for what's in the attic or crawlspace
I'm a remodeler, not an HVAC contractor, but I've been burned the same way: hidden conditions show up once you start, and in older homes touching one system often means bringing others up to current code. Put an allowance or a clear exclusion in the bid for duct and access problems you can't see on the walkthrough.
Only one option on a replacement
A homeowner replacing a system is usually comparing efficiency levels and warranties across bids. Showing two or three tiers on the same estimate lets them pick without calling someone else for a second number.
Sending the bid and never following up
A lot of jobs are won on the second or third follow-up, not the first estimate. Most contractors send a bid and never chase it, so the one who follows up stands out. I forget too when I'm busy on a job site, which is why I let software do it.
Where EstimationPro Fits (and Where It Doesn't)
I built EstimationPro because my own remodeling estimates took hours. HVAC is one of the trades you can pick when you start an estimate. You describe the job with photos, a voice walkthrough, notes and measurements, and AI builds a priced line-item estimate with rates adjusted for your region. You review and edit every line, set your markup, and send a branded PDF or a link the customer can approve. Good-Better-Best tiers are built in. Contractors save 2+ hours per estimate.
Estimates sent from EstimationPro get automatic follow-up: at 24 hours if unopened, 48 hours after opening with no response, and a final one at 7 days. Pro adds e-signatures, deposits and invoices.
What it does not do:
- Load calculations or duct design
- Dedicated duct takeoff from scaled plan sets
- Dispatch, crew routing or field-service management
- Ordering materials
Pricing: 3 AI estimates free with no card. Then Starter at $79 a month (10 estimates) or Pro at $149 a month (25 estimates). No contract. 30-day guarantee: saves you time and beats your spreadsheet, or your money back.

Frequently Asked Questions
Do I need load calculation software to estimate HVAC jobs?
You need a load calc to size new equipment, and estimating software usually does not do one. Design suites like Wrightsoft Right-Suite Universal combine the load, duct design, a parts list and a proposal in one Windows program. If you only need the number, run the load first (our HVAC load calculator gives a starting point, and the Manual J guide walks through it), then price the tonnage the load calls for. Check whether your jurisdiction wants a load calc with the permit.
Flat-rate pricebook or a priced estimate for each job?
Both, for different work. A flat-rate pricebook charges one fixed price per task, which fits repeat service and repair calls a tech can quote at the door. Replacements and new installs vary with equipment, access, line set and duct condition, so most contractors price those job by job. ServiceTitan, for example, sells flat-rate pricebooks and Good-Better-Best presentations built from them.
Can a spreadsheet or template do the job instead?
At low volume, yes. An HVAC estimate template covers equipment, line set, electrical, ductwork, labor and permit lines. What a template does not do is send the bid, show you whether the customer opened it, follow up or take a deposit. Weigh those against how many bids you send a month.
How should I price equipment with the refrigerant change?
Get a current quote from your distributor for the exact condenser or heat pump, coil and furnace or air handler before the bid goes out, and put model numbers on it. EPA says most major manufacturers have already moved new residential equipment to R-454B, and in September 2025 it proposed dropping the installation deadline for R-410A equipment made before 2025. Check the current rule and what your distributor actually stocks.
Does EstimationPro do Manual J, duct design or takeoff from plans?
No. It does not run load calculations, design duct systems or do a dedicated duct takeoff from scaled plan sets. It builds the estimate from what you capture on a site visit: photos, a voice walkthrough, typed notes and measurements. You size the equipment from your own load calc and decide what the job needs.
