Vento vs Field Ascend
Field Ascend is field-service management software for trade and service businesses. Field Ascend covers scheduling, job tracking and field-service admin across trades. Vento is purpose-built for air conditioning: it sizes the system, designs it and produces the proposal, not just manages the field work.
The comparison below is at a category level: both handle the day-to-day admin of running a trade business, but only Vento is built around air-conditioning design and engineering. Field Ascend's exact features vary by plan and change over time — confirm current details on Field Ascend's website.

"Varies" means the capability exists in some form or depends on plan/integration. General field-service platforms cover many trades; air-con-specific engineering like room-by-room heat-load and refrigerant system design is not something they set out to do. We don't speak for Field Ascend's product — verify current capabilities directly.
General field service, configured to fit
Field Ascend is field-service management software for trade and service businesses: jobs, engineers, scheduling and the record of what was done. Like most platforms in this category it is built to be adapted — configured to the way your business works rather than arriving with one trade's assumptions baked in.
That flexibility is the selling point, and for a multi-trade service business it is the right one.
Configurable is not the same as built-in
Here is the trade-off worth being clear-eyed about. A configurable platform can usually be made to hold air-conditioning information — custom fields for refrigerant charge, a document upload for a drawing, a checklist for commissioning.
What configuration does not do is the arithmetic. It will not calculate a room's heat load, match a unit's capacity against it, check a pipe run, work out CO₂e from charge and GWP, or schedule the next leak check from that figure. Those are calculations, not fields, and they either exist in the product or they do not. Confirm directly with Field Ascend what is built in rather than configurable.
Vento has them built in, because it was built for one trade and can afford to assume what the job is. See everything Vento includes.
What to compare on
Ask what setting it up actually involves: who does the configuration, how long before you are live, and what that costs on top of the subscription. A platform that needs a month of someone's time is more expensive than its price list suggests.
Then compare like for like: with Vento you are live on your next survey, because there is nothing to configure — the air-conditioning assumptions are the product.
Vento’s pricing is published and flat: plans start at £49 a month, with the Professional plan at £149 a month including 3 seats and extra seats at £25. Every plan has a 14-day free trial and there is no multi-year term to sign. See the full pricing for what each plan includes.
Frequently asked questions
Can a general field-service platform be configured for air conditioning?
It can usually be configured to store air-conditioning information in custom fields. What configuration cannot add is the calculation — heat load, capacity matching, CO₂e from charge and GWP, leak-check scheduling. Ask any vendor which of those are built in rather than something you would set up yourself.
How long does Vento take to set up?
You can run your first survey the day you sign up. Loading your own equipment list and prices is worth doing early so quotes use your buy prices rather than catalogue ones, and that is a short job rather than an implementation project.
Does Vento do planned maintenance?
Yes — recurring service plans, certificates, and leak-check due dates that come out of each system's refrigerant charge rather than a manually kept diary.
Where Vento wins for air-con installers
- The engineering is built in — Room-by-room heat load, capacity matching and scaled system drawings are part of the workflow — not a separate CAD seat, spreadsheet or add-on a general tool can't provide.
- Purpose-built, not adapted — Vento only does air conditioning, so surveying, sizing, drawings and F-Gas fit how your jobs actually run — where Field Ascend is built to serve many trades at once.
- Win the job on the visit — Survey, design, proposal, e-sign and deposit happen in one visit, so you leave with a signed job and money in the bank.
If you run several trades, a broad platform like Field Ascend may suit you. If air conditioning is your business, Vento is built for exactly that.
