Air conditioning in Marks Gate
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. Need an air conditioning installer for Marks Gate? We’re based in East Grinstead and cover London and the South East, as an F-Gas certified company with NICEIC approval.
A typical install in Marks Gate is an indoor unit high on an outside wall, a neat pipe run and an outdoor unit on a bracket or ground pad, with the condensate drained away safely.
In a village like Marks Gate, many homes are older, and some are listed. We check that first, because permitted development does not apply within the grounds of a listed building.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

Why deal with it now?
The best time to plan air conditioning is before the hot weather, not during it. When people buy in a hurry, the unit is often the wrong size or badly placed, which is costly to undo. Booking the survey early gives you time to weigh up the options. Booking before summer means the work in Marks Gate is done before the hot weather.
Several rooms, units or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.
Why people in Marks Gate choose us

What we do, step by step
Every visit follows the same order: agree the plan on site, put the dust sheets down, carry out the job, check the system and explain it all to you. On site, the work takes a day or more, depending on the number of rooms, the pipe routes and the access. Rural lanes and tight entrances are worth mentioning before a visit to Marks Gate.
- We survey the property, or work from your pictures for a simple job.
- Output, positions and price are settled before anything is booked.
- We protect the area, then fit both halves of the system.
- Pipework, cable and drain are run, the circuit is connected and the pipework is pressure tested and evacuated.
- It’s switched on, checked and handed over with its records.
Preparing for the visit
- Have the make and model of any existing unit to hand
- Tell us about parking and loading
- Let us know where the consumer unit is
Ask for a quote
Our prices page gives typical ranges, but your quote is based on your job, because no two buildings, rooms or systems are the same. After a look at the job, by photos or a survey, the price is fixed. To start, ring us on 07833 053749 or write to us at info@aircondoctor.co.uk.

How we price air conditioning
We quote each job individually. These are the things that affect it:
- Whether the existing supply is suitable
- How easy the units are to reach
- How many units are involved
Putting the work off seldom saves money. Small problems, from blocked filters to slow leaks, tend to get worse, and a struggling system uses more electricity to do less. If you are not sure what’s needed, call us on 07833 053749 and we will give you an honest view and a fixed price.
Helping us quote
When you contact us, these details help:
- The remote or wall controller showing any error
- Where the property is and what kind of building it is
- Your installation or service records
To help us quote: where the property is and what kind of building it is, 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, give us a ring on 07833 053749 or write to us at info@aircondoctor.co.uk.
Marks Gate: your questions answered
Is Marks Gate in your area for air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Marks Gate is part of that. Just ring us on 07833 053749 or write to us at info@aircondoctor.co.uk with a few details.
Will air conditioning in Marks Gate need planning permission?
It comes down to the building and the spot chosen for the outdoor unit. Around 7 listed entries sit within 0.5 miles of central Marks Gate. Put simply: reversible systems on houses can be permitted development, cooling-only ones can’t, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact Barking and Dagenham council, which is normally the planning authority for Marks Gate.
Do I get paperwork after the visit?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
What size air conditioning unit do I need?
We size each room on the survey, from its size, glazing, orientation and use. An undersized unit never catches up, and an oversized one cycles and wastes energy and we explain the output we recommend.
Can you look at a system you didn’t fit?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Send us the make and model, and any records you have.
Do you work on all makes?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.
Who is responsible for leak checks?
Responsibility is shared between the operator, typically whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.

How the job changes from property to property
Outdoor unit positions
On flats and terraced houses, space outside is often the deciding factor. Every option is checked on the survey and we flag any consent you may need.
Pipework and condensate drains
Between the units run the refrigerant pipes, the control cable and the condensate drain. We agree the route with you before we drill, and keep it as short and neat as the building allows.
From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
