Air conditioning in NW26: how it works
We approach an installation much as a doctor approaches a patient: the survey diagnoses what the rooms need, the installation is the treatment and commissioning is the sign-off. The sign-off includes testing every mode, showing you the controls and handing over the F-Gas records. We are often asked to deal with rooms under the roof that stay hot into the night and a business premises that overheats in summer, on VRF systems, wall-mounted split systems and multi-split systems.
Protection comes first: sheets over the floor and any furniture nearby, and we ask before moving anything. After that, anything electrical is made safe and we start. It takes about a day for a single-room system, longer for multi-room and ducted systems, and we tidy up before we leave.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Next, a recommendation for each room and a fixed price.
- Then the work: units up, pipes and drain run, and a new circuit where necessary.
- Checks: a pressure test for leaks, then a vacuum to clear moisture.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.

Photos are enough for some jobs; others need a visit first. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.
Around Harlesden
Locally, jobs take us to houses, flats and workplaces close to John Keble CofE Primary School, Royal Oak Inn and Roundwood Park, among other places. Other local landmarks include The Swaminarayan School (1 mile north-west), St Claudine's Catholic School for Girls (within half a mile north-east) and Church of All Souls (under half a mile south). Harlesden has its own railway station: Willesden Junction station. Other landmarks nearby include Central Middlesex Hospital (1 mile west) and Brent Museum and Archives (1.1 miles north-east). For a walk, there’s Castlebar Hill and The Long Water.
Air conditioning across NW26: local notes
Our air conditioning work across NW26 takes in places such as Harlesden, College Park and Old Oak Common and the smaller places around them. We cover every place we list for NW26, 3 in all.
Our area stretches from Greater London through Surrey, Kent and Sussex to Hampshire, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and NW26 sits within it. You reach the same people wherever you are in it.
Harlesden: With historic houses such as Pitzhanger Manor about 3.1 miles south-west, it’s a reminder that older homes nearby may be listed, which changes the planning rules. If you work from home near Willesden Junction station, a home office that overheats is one of the easiest rooms to cool.
Safe owner checks
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
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.
Why it fails
Rooms overheat mostly because of heat they gain during the day. Sun through large windows, roof lights and glazed doors is the biggest source in many rooms, and the heat lingers long after the sun has moved round.
Customers normally contact us after spotting something like this:
- Portable units that are noisy and barely cope
- Not knowing which system, size or brand to choose
- An ageing air conditioning system near the end of its life
- Rooms that get too hot to sleep or work in
Why deal with it now?
New systems now use lower-impact refrigerants. From 2025, single splits under 3 kg can’t use refrigerants with a GWP over 750, which is why R32, with a GWP of 675, is now common. R410A, used in many older systems, has a GWP of 2088.
Comparing quotes
- If the quote is based on a survey, photos or a diagnosis
- Whether you get F-Gas records where refrigerant is involved
- Why the equipment they’re quoting suits the job
- Whose warranty applies, and on what terms
Fixed-price quotes for air conditioning in NW26
The diagnosis comes before the price. The main factors are:
- A single visit or a regular plan
- The equipment or parts the job needs
- The pipe route between the units
- What we find on the survey or diagnosis
The price reflects the work, not guesswork. That is why we look at the job first, from pictures or on a survey, and why the quote is fixed before work begins.
Helping us quote
You do not need the technical terms. Just send:
- Your consumer unit or fuse board
- A few pictures of the room and the wall the unit is on, or will go on
- The outside wall, roof or yard where the outdoor unit sits or would go
- The rating plate or label on any existing unit

Questions from NW26
Do you survey before quoting?
Yes. Every job is looked at first, on a survey, or from your photos and details where the job is simple. Then you get a fixed-price quote.
Can the outdoor unit go on a roof or at ground level?
The position is agreed on the survey, not on the day. It needs space around it to breathe and room for an engineer to service it, and a position facing a road can bring extra planning considerations. We will tell you what to check before we fit it.
Is the equipment covered by a warranty?
Warranty comes from the manufacturer and depends on the brand and product. Daikin, for instance, gives a standard 2 years on split air conditioning and we explain the terms for your brand on the quote.
Will I get records for the system?
Yes. You get a written record of every visit, including F-Gas records for any refrigerant work. Keep them with the manual and the warranty documents.
Do you work in NW26?
Yes. Our engineers work in NW26, within the South East and London area we cover. We are based in East Grinstead, West Sussex.
How long will the installation take?
It takes a day or more, depending on the number of rooms, the pipe routes and the access. We confirm the time when we quote, so you can plan around it.
Can you look at a system you didn’t fit?
Yes. Systems fitted by other companies are fine from all the leading brands. Tell us the make and model and send any paperwork you have.
