Safe owner checks
On air conditioning, the filters in the indoor unit are normally the one part owners can clean where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and phone 07833 053749 or drop us a line.
Commercial air conditioning in Cookham Dean, done properly
Air conditioning systems with an effective rated output over 12 kW must have a TM44 inspection at least every 5 years. An accredited energy assessor carries it out; we are not assessors, but we prepare systems for inspection and act on what the report finds. If you are dealing with changes of use that need a new layout and leak check schedules that have slipped, we can help.
Around Cookham Dean, there’s normally space for outdoor plant away from the road.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

Different systems, different jobs
F-gas records and TM44
The operator of a system at or above 5 tCO2e must have it leak checked and keep records. We carry out the checks and provide the records.
Hotels and schools
In schools, the holidays are the natural time for installation, with the programme agreed well in advance.
What we do, step by step
We book the visit for a day and time that suit you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your pictures or the details you gave us. Anything unexpected is raised with you before we go further. From there, the work takes from a couple of days for a few cassettes to a planned programme for a whole building. Photos of the existing unit help with repairs and servicing in Cookham Dean.
- An engineer walks the building with you to understand its layout, its users and its heat sources.
- We send a fixed-price quote showing the system, the unit positions and how the work will be phased.
- The work is planned around your opening hours, with out-of-hours or phased work where it helps.
- On site, the team mounts the plant, runs and proves the pipework, and wires the controls.
- Commissioning, F-gas records and a handover of the controls finish the job.
How to prepare
- Dig out any previous service or F-Gas records
- Tell us about any building rules, permits or sign-in
- Mention any parking restrictions near the property
Getting a quote
Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.

Cookham Dean questions
Is planning permission needed for air conditioning in Cookham Dean?
The answer turns on the property and where the outdoor unit would sit. Central Cookham Dean sits inside a conservation area. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask Windsor and Maidenhead council, which is normally the planning authority for Cookham Dean.
Is Cookham Dean in your area for commercial air conditioning?
Yes. Cookham Dean is one of the places we cover. To start, call us on 07833 053749 or email us with a few photos.
How long will it take to install air conditioning in our building?
As a guide, it takes anything from a day or two for a small office to several weeks of phased work on a large building. Phased or out-of-hours work may extend it but keeps the business running.
Do I get paperwork after the visit?
Yes. Each visit is written up, including F-Gas records for any refrigerant work. Keep them with the manual and the warranty documents.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for breakdowns that can’t wait. Ring 07833 053749 any time and explain the problem.
Will you make a mess?
Protection goes down first: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up, with F-Gas records where refrigerant work is involved.
