About our commercial air conditioning in Mill Hill
Businesses cannot always stop for an installation. Work can be done in the evening, at weekends or in phases so disruption is kept down. The programme is agreed before we start. If you are dealing with older systems on refrigerants that are getting scarcer and ageing air conditioning that keeps breaking down, we can help.
London buildings in Mill Hill can have little space for outdoor plant, so condensers often go on roofs, in light wells or in plant rooms. VRF systems can serve many indoor units from a small number of outdoor units, which helps in dense areas.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

Safe owner checks
Owner care supports servicing; it doesn’t replace it. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
Mill Hill: your questions answered
Can I have air conditioning in a flat in Mill Hill?
In many cases, yes, once the lease and the building’s rules are checked. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Can I fit air conditioning in Mill Hill without planning permission?
It depends on the property. The centre of Mill Hill is in the Mill Hill Conservation Area. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the local planning authority (for Mill Hill, typically Barnet council) when it matters.
Will you make a mess?
We start with protection: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards before we leave.
Is Mill Hill in your area?
Yes. We work in Mill Hill and the rest of Greater London, as part of our area across London and the South East. For a fixed-price quote, call us on 07833 053749 or write to us at info@aircondoctor.co.uk.
What kind of air conditioning can you install in a business?
We install wall-mounted, cassette, ducted, multi-split and VRF systems. We recommend the type that suits your space.
What accreditations do you have?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Do you offer commercial maintenance contracts?
Yes, maintenance contracts cover servicing, F-gas leak checks and records. We agree the schedule and cost up front.
Why deal with it now?
TM44 inspections are required at least every 5 years for systems over 12 kW. Acting on the findings can improve how the system runs and we can do the work they recommend. Getting the work done in Mill Hill before summer avoids the busiest weeks.

The process
Our engineers arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. The work itself takes as long as the site and the system need, from a short install to a phased project planned around opening hours. If your building in Mill Hill has a managing agent, a concierge or sign-in rules, mention them when you book.
- You tell us about the building and what’s needed.
- We survey the site to check heat gains, layout and access.
- We set out the options, the price and the programme.
- Installation goes ahead around the business.
- We commission it, hand it over and can set up a maintenance contract.
Preparing for the visit
- Make sure we can reach the outdoor unit, or where it will go
- Let us know if the building has a permit or sign-in process
- Mention any parking restrictions near the property
Ask for a quote
Here’s what helps us quote: where the property is and what kind of building it is, pictures of the rooms or units, the brand and model of anything already fitted and any symptoms, from error codes to drips. Once you have those, call 07833 053749 or drop us a line.

System by system
Ceiling cassettes
Installing a cassette needs room in the void and a way to drain the water. Many have a built-in pump to lift the condensate and that’s checked when it’s serviced.
Server and comms rooms
Server room systems need regular servicing to stay reliable and we can cover it under a contract.

Each of those is a different cooling job, from kitchen heat to quiet bedrooms and server rooms. London commercial jobs typically involve a landlord or managing agent, and plant space is often tight.
