About our commercial air conditioning in Crooked Billet
Every commercial job is commercial systems priced after survey. We look at the building, the people in it, the equipment and the hours it’s used, and a fixed-price quote follows. That way the system fits the site and the price is clear before work starts. Common call-outs are for planning ahead for the HFC phase-down and installs that must fit around trading hours, on wall-mounted split systems, ceiling cassettes and ducted systems.
London buildings in Crooked Billet can have little space for outdoor plant, so condensers often go on roofs, in light wells or in plant rooms. VRF systems keep outdoor plant down by serving many rooms from few outdoor units.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

How it works
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 photos or the details you gave us. Anything unexpected is raised with you before we go further. From there, the work takes as long as the site and the system need, from a short install to a phased project planned around opening hours. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in Crooked Billet.
- We visit the site to look at the building, how it’s used and what the system needs to do.
- The written quote is fixed and lists the plant, where it goes and the order of works.
- The work is planned around your opening hours, with out-of-hours or phased work where it helps.
- Indoor and outdoor units, pipework, condensate and controls are installed and the electrics connected.
- The system is commissioned and you receive the F-gas records, handover notes and manufacturer paperwork.
Preparing for the visit
- Tell us about any building rules, permits or sign-in
- Make sure someone can let us in at the agreed time
- Move furniture away from the wall where we’ll be working
How to get 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, you get a fixed price before any work is booked.

Safe owner checks
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. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
What commercial air conditioning can’t fix
It’s worth knowing the limits before booking:
- Planning permission or landlord consent on your behalf
- Building work beyond the installation itself
- Acting as the energy assessor
If in doubt, give us a ring on 07833 053749 or send an email and we will say what we think.
What the work covers

What commercial work looks like in Crooked Billet
Food Standards Agency records list about 208 restaurants, cafés and canteens, about 6 hotels and guest houses and about 28 schools and colleges in and around Crooked Billet, up to about a mile and a half out. Each of those is a different cooling job, from kitchen heat to quiet bedrooms and server rooms. The 2021 Census found about 45% of households live in flats. In mixed streets, commercial outdoor units have to be placed and sized with the homes nearby in mind. In London, commercial installs often need landlord consent, agreed plant positions and out-of-hours working.
If you look after a school such as Wimbledon College, classroom, office and IT room cooling is usually installed in the holidays. Churches and halls such as Christ Church are often used a few hours at a time, which suits a system that heats or cools a space quickly, once consents are in place.

Common questions in Crooked Billet
Can I fit air conditioning in Crooked Billet without planning permission?
The answer turns on the property and where the outdoor unit would sit. Central Crooked Billet sits inside the Wimbledon West Conservation Area. Permitted development only covers heat pumps that are not used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where necessary, we check with Merton council, which is normally the planning authority for Crooked Billet.
Is Crooked Billet in your area for commercial air conditioning?
Yes. Crooked Billet is one of the places we cover. Tell us a little about the job and we’ll take it from there.
What are the F-gas responsibilities for commercial air conditioning?
The duties depend on how much refrigerant the system holds. Systems at or above 5 tCO2e need leak checks and records, and from 500 tCO2e automatic leak detection is required.
Do you provide ongoing maintenance for businesses?
Yes, maintenance contracts cover servicing, F-gas leak checks and records. The visits and price are fixed with your quote.
Will skipping a service affect the warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim and we will tell you what your brand asks for.
Which commercial systems do you fit?
Wall-mounted, cassette, ducted, multi-split and VRF or VRV systems. We recommend the type that suits your space.
How are commercial air conditioning installs priced?
After a site survey, with a fixed-price quote. The number of zones, the type of system, access and timing all play a part.
What affects the quote in Crooked Billet
The survey or diagnosis tells us what the work involves. We look at:
- Access, including height, roofs and ladders
- The type of system, from a single split to a larger system
- How many units are involved
The pipe route, the height of the units and how we reach them can all change the price. Each of those is built into the quote and give you a fixed price before work begins.
Asking for a quote
To speed up the quote, please include:
- The remote or wall controller showing any error
- The address and the type of property
- The paperwork from the last service, if you have it
Every quote shows the VAT clearly, and the rate that applies to your job is stated. VAT can differ between homes and businesses and between kinds of work, so we confirm it in writing rather than guess. To get one, phone us on 07833 053749 or use the quote form.
