HVAC & Sheet Metal Calculator: air flow, duct offset tools for tradesmen.
"AC Calculator - HVAC Sizing" wins the first glance for "hvac calculator": screenshot 1's "Find the Perfect AC Size for Your Space" and screenshot 2's labelled room inputs make the job obvious. "HVAC & Sheet Metal Calculator" trades that immediacy for feeling and credibility, pairing tradesmen-at-work photos with "Journeymen Save Time and Avoid Costly Errors" and a faceplate branded by a named trade-calculator maker. The gap for "AC Calculator - HVAC Sizing" is entirely human proof: no person, no room, no numbers anyone can verify.

App B
Value Proposition
A leads"AC Calculator - HVAC Sizing"'s first screenshot states "Find the Perfect AC Size for Your Space", and screenshot 4 delivers a suggested capacity of 30,000 BTU/h.
"HVAC & Sheet Metal Calculator" opens on an "Angle 53.13512" readout under "Advanced Math for the Trades"; the concrete payoff only arrives on screenshot 2.
Clarity
A leadsScreenshot 2 shows labelled inputs for ceiling height, room width and occupants producing "22,841 BTU/h"; screenshot 4 adds tons, kW and kcal conversions.
"HVAC & Sheet Metal Calculator"'s keypad carries trade-only labels like "Seg Radius" and "Fan Law 3"; screenshot 3's bullets explain the functions more plainly.
Emotional Hook
B leadsCallouts read "Your ideal AC size is ready!" and "Perfect match for your space and needs", but no room, installer or homeowner appears anywhere.
Screenshot 2 pairs "Journeymen Save Time and Avoid Costly Errors" with photos of tradesmen cutting duct, running overhead pipe and servicing a condenser.
Trust Signals
B leadsAcross all four screenshots of "AC Calculator - HVAC Sizing" there are no download counts, standards references, testimonials or certification badges.
The faceplate reads "SHEET METAL AND HVAC MATH by CALCULATED INDUSTRIES" on screenshots 1, 3 and 4; no testimonials, counts or badges beyond that.
Reviews of "AC Calculator - HVAC Sizing" split between a large group of tradespeople who call the BTU/tonnage sizing fast and useful on site and a recurring minority who question the numbers, with one user writing 'Not accurate though. Would not trust it for a/c purchase.' The same sample repeatedly asks for inputs the tool does not take, naming ceiling height, window details in advanced mode, and a metric/imperial unit switch, and a few reports describe the app failing to launch on specific Samsung devices. "HVAC & Sheet Metal Calculator" has only four reviews, too few to establish recurring pain points, though three of them are positive and one ties the app to union trade work.

HighAC Calculator - HVAC Sizing stakes out the specifying end of the job: what capacity the equipment needs to be, what it costs, and whether an inverter unit pays back. HVAC & Sheet Metal Calculator stakes out the fabrication and balancing end: duct offsets, wrapper lengths, trig, and "Fan Law Functions for Test and Balance (TAB)". For a user searching "hvac calculator" these are not competing answers to one question, they are two different jobs sharing a keyword, and the listings currently sort themselves by sizing versus field math.
App A
Positioning
Equipment sizing and cost calculator
Target audience
Anyone specifying an AC or heat pump unit
Value promise
Get BTU/h capacity, equipment type, price and running-cost comparison fast
Tone
plain, benefit-led, briskly practical
App B
Positioning
Trade math for ductwork
Target audience
Sheet metal fabricators and test-and-balance HVAC technicians
Value promise
Trade-specific dimensional math, geometry and trig on the job
Tone
feature-focused, technical, specification-style
Gap
AC Calculator - HVAC Sizing leads with the sizing decision (BTU/h, equipment type, "inverter vs. conventional energy consumption"), while HVAC & Sheet Metal Calculator leads with execution math for work already specified ("Offset functions for 'S'-shaped bends in ductwork", CFM/RPM/SP/BHP fan laws).
Opportunity
The sizing and cost-justification half of the keyword is uncontested here, so AC Calculator - HVAC Sizing can own the pre-install question of what unit to fit and what it will cost to run.
Risk
AC Calculator - HVAC Sizing names no user anywhere in the visible copy, closing instead on "in-app purchases", while the rival subtitle says "for tradesmen", so a working installer scanning the results may read it as a homeowner estimator and never open it.
Strategic advantage
The running-cost comparison between inverter and conventional units is a selling argument, not just a number, which makes AC Calculator - HVAC Sizing useful to installers and dealers who have to justify a unit choice to the person paying for it.
Missed opportunity
Neither listing claims a defensible basis for its numbers, no reference to load-calculation method, sourcing of the price data, or accuracy the user can put in front of a customer. Trustworthy-enough-to-quote-from is open ground in a category where both sides currently sell raw calculation capability.

Slight gap
On hvac calculator, HVAC & Sheet Metal Calculator holds rank 1 and AC Calculator - HVAC Sizing sits at 10, but that gap is wider than the listings justify: AC Calculator - HVAC Sizing answers the sizing question most searchers of this term actually have, and comes out narrowly ahead overall. The rank looks contestable rather than locked, because the top slot is held by fabrication and balancing math sharing a keyword with a different job.
Why it wins
AC Calculator - HVAC Sizing owns the specifying end of the work, BTU/h, equipment type and inverter versus conventional running cost, and its first screenshot states the job outright with "Find the Perfect AC Size for Your Space", while HVAC & Sheet Metal Calculator leads with duct offsets and fan laws for work already specified. Its review base is also large enough to show real on-site use by tradespeople, against four reviews on the rival side.
Biggest opportunity
The phrase hvac calculator appears in neither the title nor the short description of AC Calculator - HVAC Sizing, whose "Air conditioner or Heat Pump" line restates scope and names no user, so the keyword and the audience are both open ground on the listing that already has the stronger positioning.
Next priority
Worth testing is a short description that carries the phrase plus the payer-facing outcome, such as "HVAC calculator for installers: BTU, tons, kW and running-cost payback", since the rival subtitle says "for tradesmen" and an installer scanning hvac calculator may currently read AC Calculator - HVAC Sizing as a homeowner estimator. Pair it with showing the assumptions behind each BTU result, which is the recurring accuracy doubt that could erode the lead.
