Service & Maintenance
Planned maintenance that keeps systems running and avoids surprises.
What we offer
Tailored service contracts for residential, commercial and industrial HVAC. We catch issues early, document everything for compliance, and prioritise your call-outs.
Planned maintenance answers a different question to a breakdown call. Nothing has failed yet, the point is to keep it that way, and to be able to prove the equipment has been looked after. Every contract begins with a survey that produces an asset register: each unit listed with make, model, serial number, refrigerant type and charge, location, access requirements and age. Without that list, maintenance is guesswork and any quote is fiction. It is common to find at least one unit on site that nobody knew was there.
Visit frequency comes from the equipment and its duty rather than from a house rule. Comfort cooling in an office generally suits an annual or twice-yearly cycle timed either side of summer. Air handling units in commercial use want two visits as a minimum, quarterly where duty is heavy. Domestic MVHR is usually annual filter work with a longer interval for full recommissioning. Kitchen extract is governed by cooking hours under the TR19 Grease standard, and boilers and oil-fired plant stay annual whatever else is agreed.
A planned visit is a measurement exercise with a clean-down attached. Depending on the asset that means filter and belt changes, coil and condensate cleaning, bearing and vibration checks, electrical readings across motors, drives and contactors, refrigerant pressures and superheat, combustion analysis on fuel-burning plant, function testing of controls and safety devices, and flow figures compared against design or against the previous visit. Recording the numbers is the part that matters. One set of readings tells you the plant works today; a run of them tells you what is quietly getting worse.
Contracts carry the paperwork side too, which is usually what gets forgotten until somebody asks for it. Under the F-Gas Regulations the operator of refrigerant-containing equipment must keep records of quantities added and recovered, and of leak checks, for several years. Insurers routinely ask for evidence of kitchen extract cleaning to the TR19 Grease standard before settling a claim. Ventilation commissioned to Part F only stays compliant if airflows are periodically verified. That documentation is issued after each visit and held on file against the asset.
Timing is planned backwards from the season and forwards from your operating hours. Cooling is best serviced in spring, before the first hot week finds every weak component at once. Heating and oil-fired plant are better in late summer and early autumn, while parts are readily available. Schools take their programme in the holidays, hospitality outside service, industrial sites around planned shutdowns. We agree the calendar at the start of the contract so keys, permits and escorted access are arranged before anyone travels.
Each visit produces a written report against the asset rather than a generic tick sheet: what was found, what was done, the readings taken, consumables used, and recommendations split into what needs attention now and what can be planned. That split is deliberate — it separates genuine remedial work from items that can wait for the next budget cycle, and gives warning before a unit reaches the end of its life instead of a surprise on the coldest morning. An annual condition report pulls the whole estate together in one place.
- Asset register built from an on-site survey
- Planned preventive maintenance to an agreed calendar
- Readings and findings logged against each individual unit
- F-Gas, TR19 and Part F records held on file and issued
- Filters, belts and consumables ordered ahead of the visit
- Priority attendance for contract sites
- Annual condition report and replacement planning
Common questions
- What is actually included in a maintenance contract, and what is not?
- Included: the scheduled visits, labour, the standard consumables agreed at the outset such as filters, belts and cleaning materials, all readings and function tests, and the written report and compliance records afterwards. Not included by default: repair parts, remedial works identified during a visit, and anything arising from damage or misuse — those are quoted separately. The scope is written against your asset list rather than left open to interpretation later.
- How many visits a year does our equipment actually need?
- It varies asset by asset, and the survey settles it. Manufacturer requirements, warranty conditions and how hard the plant is run all pull the number one way or the other, as does the environment — a unit in a dusty or greasy space works through filters far faster than an office cassette. We would rather set an interval we can justify from the equipment in front of us than apply one figure across a whole site.
- We have never had a service contract — where do you start?
- With a survey. An engineer walks the building, lists every unit with make, model, serial, refrigerant type and charge, records access constraints and notes current condition and anything obviously outstanding. That produces the asset register and a proposed visit calendar. Where the survey turns up work needed before maintenance is meaningful, we separate it out as its own job so a contract does not quietly absorb an existing backlog.
- Do you keep the records we need for compliance and insurance?
- Yes. Service reports, refrigerant additions and recoveries, leak-check dates and results, airflow readings and kitchen extract cleaning evidence are recorded against the asset and issued after each visit. F-Gas record-keeping obligations sit with the operator of the equipment, so having everything in one place matters when an insurer, auditor or incoming facilities manager asks. The whole file can be supplied on request at any point.
- Can visits be scheduled around our opening hours?
- Yes, and most commercial maintenance is done outside trading hours as standard: kitchens overnight, offices early morning or at weekends, schools during holidays, industrial plant around planned shutdowns. The calendar is fixed at the start of the contract year and each visit confirmed in advance so keys, permits and escorted access are arranged beforehand. Out-of-hours working is normal for us rather than something to be negotiated each time.
- We have several sites — can they go on one contract?
- They can. Each site is surveyed individually so it gets its own asset register and visit frequency, then all of them are coordinated under a single agreement with one point of contact. Reporting is consolidated, giving one view of what has been done across the estate and what remains outstanding. Visit calendars are staggered to suit each location's operating pattern and access arrangements.
