About our air conditioning in Mongewell
Single-room systems are typically £1,200–£2,200 + VAT, while a two-room multi-split is typically £2,800–£4,500 + VAT and three to five rooms £4,500–£8,500 + VAT. Supply, installation, commissioning and F-Gas documentation are all included, with commercial and VRF systems priced after a survey. Whether you call it air con, air conditioning or an air-to-air heat pump, in Mongewell it means the same thing to us: the right unit in the right place, fitted and commissioned properly.
Most installations here are a wall-mounted indoor unit, a short pipe run through the wall and an outdoor unit on the back or side of the property, with the condensate drained away safely.
Around Mongewell, many people choose a system that heats as well as cools, which suits rooms the main heating does not reach well, such as a garden room or loft.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

- Wall-mounted split systems
- Multi-split systems
- Ducted systems
- Air-to-air heat pumps
- VRF systems
What we do, step by step
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. On site, it takes anything from a day for one room to several days for a multi-room or ducted system. Photos of the room and the outside of the property help us plan a visit to Mongewell.
- We survey the rooms and the outside of the property, or work from photos and details for simple jobs.
- The quote is fixed and shows the equipment, where each unit goes and what’s included.
- On the day, we fit the indoor and outdoor units and run the pipework, cable and condensate drain.
- We connect the supply, pressure test the pipework and evacuate it before the refrigerant is released.
- Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.
Before we arrive
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Mention any managing agent or landlord rules we need to follow
- Make sure we can reach the outdoor unit, or where it will go

What we’re called out for in Mongewell
Everything that uses electricity in a room ends up as heat. A small office or a busy room can warm up fast with equipment and people in it, even on a mild day.
If any of these sounds familiar, it’s worth a diagnosis:
- Fans and portables that do not keep up
- Too many options and no clear advice
- An ageing air conditioning system near the end of its life
Brightwell Manor (roughly 2.6 miles north-west) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.
What your quote should include
- Whose warranty applies, and on what terms
- Whether extra work needs your approval first
- The make and model of any parts or equipment being quoted

What you can do yourself, and what needs us
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. If you need something moved, we can quote for it.
Questions from Mongewell
Is Mongewell in your area for air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Mongewell is part of that. Get in touch with the details and we reply the same working day.
Is Mongewell within the area you cover?
Yes, and the size of the place makes no difference to how we work. A few photos and the postcode are enough to get things started.
Are you F-Gas certified?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
How long will the installation take?
Allow a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. The survey tells us how long your installation will need, so you can plan around it.
Who has to arrange F-Gas leak checks?
Responsibility is shared between the operator, normally whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Do you protect the property while you work?
Floors and furniture near the work are covered with dust sheets before work begins, and we tidy up as we go. At the end, we clear up and show you what we’ve done.
Does air conditioning work as heating?
Usually, 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.
What a customer said
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
