Owner checks or an engineer?
On air conditioning, the filters in the indoor unit are typically the one part owners can clean where the manufacturer’s manual explains how. 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.
Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It makes our diagnosis quicker, and a photo of the display helps even more.
Air conditioning installation in New Marston
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, with VRF for larger buildings. The right choice depends on the rooms, the building and how visible you want the indoor units to be, and we explain the options on the survey. Most enquiries from New Marston start with one hot room: a bedroom, a home office or a loft conversion. That’s normally a single wall-mounted split, from £1,200 + VAT.
Outdoor units around New Marston often sit on the ground or a low wall bracket at the back of the house, where it’s out of sight from the road and easy to service.
Warranty periods vary by brand and by product. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

Questions from New Marston
Do I need planning permission for air conditioning in New Marston?
It depends on the property. The Headington Hill Conservation Area is close to the centre of New Marston. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact Oxford City council, which is normally the planning authority for New Marston.
Do you cover New Marston for air conditioning?
Yes, New Marston is within the area we cover. Tell us a little about the job and we’ll take it from there.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s a legal requirement, and it also matters for the manufacturer’s warranty. We are happy to quote for the full job, supply to commissioning.
Do you work on all makes?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and tell you why.
Where will you put the outdoor unit?
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 the position can affect planning.
What does F-Gas certified mean?
Companies working on equipment that contains F gas must be certified by an approved body, and the engineers need their own qualifications. It means the refrigerant in your system is handled legally.
What does it cost to install air conditioning?
It depends on the rooms, the system and the pipe route, but a single-room split is typically £1,200–£2,200 + VAT. Long pipe runs, difficult access, a new circuit and premium indoor units push the price up, and commercial systems are priced after a survey.

When to call us in New Marston
Portable units are often where people start, and why they call us. Portables push their warm air out through a hose in the window, so the window can’t close properly and the noisy part of the unit is in the room. With a split system, the compressor lives outside.
What we are most often called about:
- Rooms that get too hot to sleep or work in
- An ageing air conditioning system near the end of its life
- An office, shop or restaurant that’s uncomfortable for staff and customers
With historic houses such as Holywell Manor about 0.7 miles south-west, it’s a reminder that older homes nearby may be listed, which changes the planning rules.

- Then the prescription: the right system and size for each room, on a fixed-price quote.
- The treatment: units fitted, pipework and drain routed, and the electrics installed.
- 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.
Preparing for the visit
