Best Air Conditioning Software UK (2026): 7 Tools Compared

"Best" depends on what you install. If you run a general trade business and air conditioning is one of many jobs, a broad field-service platform may be enough. If you install air conditioning regularly, you need the engineering — room-by-room sizing, system design and F-Gas — that general tools don't attempt. Here are the tools UK installers actually shortlist in 2026, and who each one suits.

1. Vento — best for air-conditioning specialists

Vento is the only UK all-in-one built specifically for air conditioning. It runs a room-by-room heat load (Manual J) as you survey, matches correctly sized units from a SEER/SCOP catalogue, produces scaled split/multi-split drawings, generates a branded proposal the customer e-signs, takes the deposit, and keeps an F-Gas register — one flat-price platform instead of a job tool plus a calculator plus a quote tool. Pricing is flat per tier (from £39/mo billed annually), not per user, so it stays cheaper as your team grows. Best for: air-con installers who want sizing, design, proposals and compliance in one place.

2. Tradify — best lightweight job admin

A clean, popular tool for quoting, scheduling and invoicing across trades. It's easy to use and good value for general admin, but it doesn't size a system or produce a heat-load calculation, so you'll pair it with a separate calculator. Priced per user. Best for: small firms wanting simple admin who size systems elsewhere.

3. Commusoft — best for large maintenance operations

A mature field-service and CRM platform with strong planned-maintenance, asset and scheduling features. Deep for multi-engineer service businesses, but general-trade in focus and priced per user with a minimum seat count. Best for: larger maintenance-led operations across trades.

4. Payaca — best for renewables-led quoting

Good-looking quotes, payments and workflow with a renewables slant. Capable on the sales side, but air-con design and sizing aren't its focus, and entry pricing sits at the enterprise end. Best for: renewables/heat-pump firms that also do some air conditioning.

5. ServiceM8 — best for very small teams

A lightweight job app for quoting, scheduling and invoicing small jobs. Simple and affordable, but no air-con engineering. Best for: sole traders wanting a minimal job app.

6. Joblogic — best for commercial contractors

Field-service management aimed at commercial and maintenance contractors, strong on planned maintenance and asset management. General-trade focus rather than air-con design. Best for: commercial maintenance contractors.

7. Simpro — best for complex project workflows

A powerful operations platform for larger contractors handling complex projects and inventory. Comprehensive but heavier to run and priced accordingly, with no air-con-specific sizing or design. Best for: larger contractors with complex project and stock needs.

How to choose

• Do you size and design systems? If yes, pick air-con-specific software — otherwise you'll bolt a calculator onto a general tool.
• How many users? Flat pricing beats per-seat once you have two or three engineers.
• Do you need F-Gas and Regs records? Better to have them come out of the same job than a separate system.
• Can you quote on site? First-visit proposals with e-sign and a deposit convert far better than emailed quotes.
