Air conditioning across RM9: what to expect
The best installations are planned before a single hole is drilled. We look at each room’s size, glazing, orientation and use, then agree where the indoor and outdoor units go and how the pipework, cable and condensate drain will run before you get a fixed-price quote. The work covers ceiling cassettes, multi-split systems and wall-mounted split systems, and the jobs we see most are a loft room or top floor that bakes in summer and a room that’s unbearable on warm days.
Each visit runs to the same pattern: agree the plan on site, protect the area, do the work, test what we’ve done and explain it all to you. The visit itself takes a day or more, depending on the number of rooms, the pipe routes and the access.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- Then the work: units up, pipes and drain run, and a new circuit where needed.
- 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.
How we quote
Several rooms, units or sites on one quote often makes better use of the time. Mention every unit or room you need covered, and you’ll get one fixed price.

Getting a price
Here’s what helps us quote: the address and the type of property, photos of the rooms or units, the make and model of any existing system and anything you’ve noticed, such as an error code or a noise. Once you have those, phone 07833 053749.
Local landmarks in Becontree
We fit and service air conditioning in homes and premises around Robert Clack School, Parsloes Park and St Joseph's Catholic Primary School and the streets around them. Nearby too are St George's (less than half a mile south-east) and Eastbrook pub (0.9 miles east). Becontree’s nearest station is Chadwell Heath station, about 1.5 miles north-west. Other landmarks nearby include Redbridge Museum (3 miles west) and The Brewery (2.4 miles north-east). Not far away are Dagenham Village Churchyard.
Where we install in RM9
In RM9, as across England, the same permitted development rules apply: an air-to-air system that heats as well as cools can be permitted development on a house, but cooling-only units, listed buildings and outdoor units facing a road in conservation areas need more care.
We’re based in East Grinstead and work across London and the South East, RM9 included. Each job starts with a survey and a fixed-price quote.
Becontree: Around St George's, a quick check of the listing and conservation maps is part of planning any install. Eastbury Manor House, about 2.1 miles south-west, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.
Why act early?
There’s a tax point for homes: installing energy-saving materials in residential accommodation is zero-rated until 31 March 2027, then 5%. HMRC says most air conditioning units are air source heat pumps, but each case depends on the facts and we confirm the VAT on your quote. This is general information, not tax advice.
What your quote should include
- What happens if the job turns out to be different on the day
- Proof of F-Gas company certification
- What the manufacturer’s warranty covers and for how long
- Which VAT rate the quote uses, and why
Looking after your system
Every system needs looking after, and most of it is easy. A few tips:
- Keep the handover documents somewhere safe
- Refit filters properly after cleaning
- Keep the outdoor unit clear of leaves, plants and clutter
- Flag any change in how the system sounds or performs
Commissioning is the last stage: every mode is tested before we go. Once it’s running properly, we take you through the controls and settings so you know how to get the best from it.
Report drips, noises or error codes early. Water from the indoor unit, a new rattle or a code on the display normally means something needs attention, and early repairs are typically simpler.
Different systems, different jobs
Multi-split systems
A multi-split runs several indoor units from one outdoor unit. It saves wall space outside and suits homes where several rooms need cooling and each indoor unit has its own controls.
Pipework and condensate drains
Air conditioning takes moisture out of the air when it cools, which the condensate drain takes away. Where it cannot fall naturally to a drain, a condensate pump lifts it, and we plan that on the survey.
How we price air conditioning
The price is fixed before any work begins. It takes into account:
- What kind of system it is
- How many units are involved
- Whether the existing supply is suitable
- The condition of any existing system
Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you are unsure, give us a ring on 07833 053749 or write to us at info@aircondoctor.co.uk and we will give you an honest view and a fixed price.
Asking for a quote
Photos let us diagnose from a distance. Try to include:
- The outdoor side of the property, including any roof or flat area
- Your installation or service records
- A short video of any fault, such as a noise or a flashing light
- The rating plate or label on any existing unit
Published ranges are a starting point; the quote is built on your property, because no two buildings, rooms or systems are the same. After a look at the job, by pictures or a survey, the price is fixed. To get going, call 07833 053749, or email if that’s easier.
RM9 questions
Can landlords and managing agents book you?
Yes. From a single let flat to offices, shops and public buildings, we work the same way: a look first, a fixed-price quote and written records.
Do you survey before quoting?
Yes. Every job is looked at first, on a survey, or from your pictures and details where the job is simple. A fixed-price quote follows.
Can I have air conditioning in a flat?
It depends on the building and the lease. Balconies, flat roofs and rear walls can all work, subject to consent, and we check the options on the survey. This is general information, not legal advice.
Is planning permission needed for the outdoor unit?
Not necessarily. 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. Cooling-only units, listed buildings, flats and road-facing spots in conservation areas are where it typically comes up and the survey picks it up. This is general information, not legal advice.
Will skipping a service affect the warranty?
For some brands, yes. Read the manufacturer’s terms, or send us the make and model and we will explain them, and book the service at the interval they recommend.
Do you protect the property while you work?
Protection goes down first: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
Why use an F-Gas certified company?
The law says any company working on equipment containing F gas has to be certified, and the engineers need their own qualifications. It’s how you know the refrigerant is being handled legally and safely.
