- A study or office that overheats during the day
- Rooms heated by plug-in heaters
- Fans and portables that do not keep up
Keeping the system healthy
Systems last better with the right care. Here’s what we suggest:
- Keep to the service interval the manufacturer recommends
- Flag any change in how the system sounds or performs
- Keep the room closed while it runs
The work area is left tidy: sheets removed, packaging cleared up and pipe holes sealed. Outside, the pipework is neatly fixed and protected, so the job looks as tidy as it works.
Book an annual service. The engineer cleans the coils and drain, checks the electrics and the refrigerant circuit and catches small problems early and keeps the warranty paperwork right where servicing is a condition.
Air con installers in Cumnor
The best installations are planned before a single hole is drilled. Each room is assessed for its size, windows, direction and how it’s used, and we agree the unit positions and the route for the pipes, cable and drain, all before the price is fixed. Whether you call it air con, air conditioning or an air-to-air heat pump, it’s the job we do every week across Oxfordshire.
New circuits are done by our NICEIC approved electricians, so the electrical paperwork comes with the installation.
Around Cumnor, many people choose a system that heats as well as cools, which suits garden rooms, lofts and extensions that the main heating struggles with.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

Fixed-price quotes for air conditioning in Cumnor
You’ll get a fixed price before work begins. It takes into account:
- Whether we need access equipment for high-level work
- Whether it’s a one-off job or part of a maintenance contract
- What electrical work the job needs
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 any work starts.
What to send for a quote
To speed up the quote, please include:
- The postcode and whether it’s a home, flat or business
- The make and model of the system, from the label
- Photos showing the indoor unit and the space around it
Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.
FAQs for Cumnor
Is planning permission needed for air conditioning in Cumnor?
That depends on the building and where the outdoor unit goes. Central Cumnor is a short walk from the Cumnor Conservation Area. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the local planning authority (for Cumnor, typically Vale of White Horse council) when it matters.
Do you cover Cumnor for air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Cumnor is part of that. Just phone us on 07833 053749 with a few details.
How long does air conditioning installation take?
Allow about a day for a single-room system, longer for multi-room and ducted systems. We confirm the time when we quote, so you can plan around it.
Can I use air conditioning to heat a room?
Most of the time, yes. Running as a heat pump, it moves heat in from outside rather than making it from electricity alone. To replace your main heating, there are extra conditions, including for the £2,500 Boiler Upgrade Scheme grant for air-to-air heat pumps.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine, on all the main brands. Tell us the make and model and send any paperwork you have.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
Do you work on all makes?
We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Landlords, agents and facilities managers
Whether it’s one property or many, the approach is the same: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
We also work for facilities teams in offices, schools and public buildings in Cumnor and across Oxfordshire. Larger buildings can be done in stages to keep disruption down.
How it works
The visit goes in the diary at a time that works for you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the photos you sent. If something is different, we talk it through with you before carrying on. After that, it takes a day or more, depending on the number of rooms, the pipe routes and the access. We plan the trip to Cumnor around you.
- First comes a site survey, or photos and measurements for a straightforward job.
- The quote is fixed and shows the equipment, where each unit goes and what’s included.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- The electrical supply is connected, and the refrigerant circuit is pressure tested and evacuated.
- We commission the system, show you the controls and leave the F-Gas records and the manufacturer’s warranty details.
Preparing for the visit
- Clear a path to the units and the space around them
- Keep pets and children away from the work area
- Mention any roof access, ladders or high-level work

A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
