Ducted systems

How we handle commercial air conditioning in Harefield
We design, install and look after air conditioning for businesses in Harefield and across Buckinghamshire. That includes offices, shops, restaurants, hotels, schools and server rooms, and each one gets a system chosen for how the space is used. We’re often asked to deal with new tenancies needing cooling and heating and staff complaining about the temperature, on server and comms room cooling, VRF systems and ducted systems.
Businesses near Harefield often have room for outdoor units on the ground at the back, which keeps them tidy and easy to reach.
Aftercare is simple, and most of it is in the manual: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. That also helps where the warranty terms ask for regular servicing.

What we do, step by step
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. The visit takes as long as the site and the system need, from a short install to a phased project planned around opening hours. We plan the visit to Harefield from the survey or your pictures.
- An engineer walks the building with you to understand its layout, its users and its heat sources.
- You get a fixed-price quote with the equipment, the layout and the programme set out.
- 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.
- We commission the system, record the refrigerant details and hand over the controls and documents.
Preparing for the visit
- Let us know if the building has a permit or sign-in process
- Clear the space around the indoor unit, or where it will go
- Dig out any previous service or F-Gas records
Getting a quote
Getting a quote is straightforward. Call or email with a few details and we’ll come back to you the same working day. Where a survey is needed, we arrange a time that suits you.

For landlords and property managers
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Let us know who will give us access and who the records should go to and we’ll copy in whoever needs it.
When the building owner and the occupier are different, the lease or tenancy agreement normally sets out who maintains what. We can quote either party, and the paperwork can go to both.

Questions from Harefield
Is Harefield in your area for commercial air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Harefield is part of that. Get in touch with the details and we reply the same working day.
Do you cover smaller places like Harefield?
Yes, smaller places are covered as well as towns. Send a few details and pictures, and we reply the same working day.
What does the operator have to do under the F-gas rules?
The duties depend on how much refrigerant the system holds. From 5 tCO2e, leak checks and records are needed, and from 500 tCO2e automatic leak detection is required.
Who has to arrange F-Gas leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We will work out which band applies to yours.
Which brands do you work with?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
How are commercial air conditioning installs priced?
Each commercial job is surveyed and then priced. It means the system and the programme fit your building, and the quote you get is fixed.
Do I need planning permission?
Not always. Permitted development can cover a heat pump on a house, including an air-to-air system that heats as well as cools since 2025, provided the conditions are met. Permission is more likely to come up for cooling-only units, listed buildings, flats and road-facing positions in conservation areas and the survey picks it up. This is general information, not legal advice.
What you can do yourself, and what needs us
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Good habits make our visits easier, not unnecessary. Simple care keeps the air moving through the system, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
