HVAC maintenance software,
built by people who've done the work.
PPM that builds its own jobs, F-Gas-ready records on every asset and a schedule that absorbs reactive work without losing the plan.
Built by people who've run real maintenance contracts — not a software company guessing at what a missed PPM visit or an overdue leak check actually costs you.
HVAC maintenance is too important for spreadsheets.
The day-to-day reality for most HVAC contractors looks like this.
PPM visits quietly slipping
Planned preventative maintenance dates tracked in spreadsheets get missed, and a skipped service is the breakdown you'll be fighting next week — usually at the worst possible time.
F-Gas records stuck on paper
Refrigerant logs, leak checks and charge calculations scribbled on site then filed in a drawer — slow to find, easy to lose, and a problem the moment an auditor asks for them.
Reactive breakdowns wrecking the plan
Emergency call-outs land with no warning and blow apart the planned schedule, leaving engineers double-booked and PPM work pushed back again and again.
Asset history scattered across vans
Each AHU, chiller and split system has a service history living in different engineers' heads and notebooks, with no single record of what was done and when.
Designed around how HVAC compliance actually works.
Curcle isn't a generic CRM with a schedule bolted on. The planning, records and reporting are shaped around F-Gas, TM44 and the manufacturer service intervals every HVAC contractor is responsible for.
- F-Gas Regulation (EU 517/2014, retained in UK law) — controls on fluorinated greenhouse gases
- Refrigerant logs and mandatory leak checks at intervals set by CO2-equivalent charge
- TM44 air-conditioning inspections for systems over 12kW under the Energy Performance of Buildings regulations
- F-Gas certification for company and engineers (Category I–IV) for refrigerant handling
- Manufacturer service intervals and PPM schedules to keep warranties and equipment cover valid
Everything an HVAC contractor needs in one place.
From the PPM schedule to the F-Gas record — connected, not scattered.
PPM contracts that build their own jobs
Set a planned maintenance schedule once and Curcle auto-generates the visits, so periodic servicing never quietly slips past due.
F-Gas-ready records on every asset
Leak checks, refrigerant added and recovered, and charge details captured against the unit — ready to evidence the moment an auditor asks.
A schedule that absorbs reactive work
Drag-and-drop reactive breakdowns onto the day without losing the plan — Curcle keeps PPM and emergency call-outs on the same board.
Full asset & service history per unit
Every AHU, chiller, split system and condenser on one register, with its complete service, parts and refrigerant history in one place.
Readings & checks captured on site
Engineers record temperatures, pressures, photos and check results from the mobile app — no end-of-day retyping back at the office.
Audit packs in two clicks
Produce a complete, client-ready compliance pack — including F-Gas and TM44 records — for any site or asset on demand.
