What happens on the day
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. You only need to give us clear access to the units, or their planned positions, and to the fuse board. The visit takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Pictures of the space and where the outdoor unit could go let us plan the work in Northend.
- You send photos, or we visit and survey the rooms and outside.
- Output, positions and price are settled before anything is booked.
- We protect the area, then fit both halves of the system.
- Connections are made, checked for leaks and pulled down to a vacuum.
- The system is commissioned, the controls explained and the F-Gas records handed over.
Before we arrive
- Let us know if the building has a permit or sign-in process
- Make sure we can reach the consumer unit or fuse board
- Unlock any gate, garage or side passage we need

Advice
Air conditioning installation in Northend
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi are among the brands we fit. The survey ends with a recommendation and the reasons for it, and the manufacturer’s warranty terms are set out on your quote. Modern air conditioning heats as well as cools: in heating mode they work as an air-to-air heat pump, so a system bought for summer earns its keep in winter too.
The outdoor unit position is the biggest single decision: we balance airflow, noise, the pipe run and access for future servicing.
Around Northend, many people choose a system that heats as well as cools, which suits garden rooms, lofts and extensions that the main heating struggles with.

Northend: your questions answered
Do you cover smaller places like Northend?
Yes. Northend is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
Can you do air conditioning in Northend?
Yes. We work across London and the South East from our base in East Grinstead, and Northend is part of that. Just call 07833 053749 with a few details.
Can landlords and managing agents book you?
Yes. From one rented home to commercial buildings, we work the same way: a look first, a fixed-price quote and written records.
Where does the outdoor unit go?
It can go on a wall bracket, at ground level or on a flat roof, chosen for the pipe route, airflow and access. We also think about noise near bedrooms and neighbours and position can affect planning.
Can I do the refrigerant work myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Whose job is it to check the system for leaks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Do you offer emergency call-outs?
Yes. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will tell you what to do first.

Air conditioning around Northend
Census 2021 figures found about 68% of households in detached or semi-detached houses. With homes like that, finding a sensible outdoor unit position is rarely hard, and a multi-split lets two or more rooms run off it. The centre of Northend lies within the Northend Conservation Area. Draw a one-mile circle round the middle of Northend and it takes in 2 conservation areas. On the National Heritage List, around 5 entries fall within 0.5 miles of the middle of Northend; Northend Farmhouse (grade II*) is one. That matters for air conditioning: permitted development does not apply within the grounds of a listed building, in a conservation area the outdoor unit can’t go on a wall or roof facing a road, and a unit used only for cooling isn’t covered at all, so we check with Buckinghamshire council, typically the planning authority here where necessary.
Starting with one room is common, and the outdoor unit can be chosen with more rooms in mind. With historic houses such as Stonor Park about 2.1 miles south, it’s a reminder that older homes nearby may be listed, which changes the planning rules.
Northend is about 8 miles north-west of Marlow, in Oxfordshire. Our engineers cover Northend for air conditioning, along with the rest of Oxfordshire. Northend is one of 443 towns, villages and districts in Oxfordshire where we work. Guildford, roughly 31 miles off, has its own page on this site.

Owner checks or an engineer?
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.
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and ring us on 07833 053749 or send an email.
Managing agents and facilities teams in Northend
Larger air conditioning systems in buildings need more than servicing: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We arrange the inspection, get the system ready and put right anything it picks up.
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. Where a building is let or managed, the lease or contract should make clear who looks after the system, and we can work for either side.
What air conditioning can’t fix
In fairness, some problems need a different answer:
- Damp or condensation caused by leaks or poor ventilation in the building (that needs the cause fixing)
- Stuffy rooms that need fresh air rather than cooling
- A building fabric problem such as single glazing or no loft insulation
Not sure which it is? You can ring 07833 053749 or send an email and we’ll tell you honestly.

“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.”
