Air Conditioning Installation & Servicing Comfort All Year Round
Wall mounted splits, multi-split and ducted systems from Daikin, Mitsubishi Electric, Fujitsu, Samsung and LG, installed, serviced and repaired by F-Gas certified engineers. Heats in winter as well as cools in summer, and 0% VAT applies on most residential installations.
How much will it cost to run?
Less than most people expect. A typical wall unit costs about 11p an hour to cool one room and about 17p an hour to heat it. Put in your own electricity rate and see what it would cost you.
Choosing between the system types
Single split. One outdoor unit serving one indoor unit. The straightforward choice for a single room, a home office or a bedroom.
Multi split. One outdoor unit serving several indoor units. Fewer outdoor units on the wall, and usually the sensible answer for two or three rooms.
Ducted. Concealed in a ceiling void with grilles in the rooms. Neatest visually, most involved to fit, and best considered during building work rather than after.

Call and talk to an engineer, or send us the details and we will come back to you with a price.
Air conditioning heats as well as cools
Modern units are heat pumps and run in reverse to provide heating. In mild weather that is frequently cheaper to run than gas central heating for a single room, which makes a unit in a home office or a conservatory useful all year rather than for a few weeks in summer. See what a unit costs to run per hour and per month at the current price cap, with a calculator you can set to your own rooms and hours.
What decides where units go
Indoor units need a route for pipework and condensate drainage to the outdoor unit, so the practical positions are usually more limited than people expect. Outdoor units need clear airflow and a sensible position for noise, particularly near a neighbouring boundary or below a bedroom window. We will walk the route with you before quoting.
Fitted right first time, F-Gas certified
Survey, supply, installation and commissioning by our own engineers, with the trunking run properly.
Planning permission
Most domestic installations fall under permitted development, but conditions apply and they are stricter on flats, listed buildings and conservation areas. We will flag it if your property looks like one of the exceptions. Do not take a blanket yes from anyone on this.
Servicing keeps the warranty
Manufacturers generally require documented annual servicing for warranty cover. See air conditioning servicing.

Questions people ask about air conditioning
How much does air conditioning cost to install?
It depends on the number of rooms and where the outdoor unit can go, so we price every installation after a free survey and give you a fixed written quote. A single-room split system is the starting point; a multi-split serves several rooms from one outdoor unit. We install Daikin, Mitsubishi Electric, LG and Samsung and there is no call-out fee in working hours.
Does air conditioning heat the house in winter?
Yes. The split systems we install are air-to-air heat pumps, so the same unit heats in winter and cools in summer. In heating mode a modern unit delivers around three to four units of heat for every unit of electricity, which makes it one of the cheapest ways to heat a single room, home office or extension.
Do I need planning permission for air conditioning?
Usually not. In England a domestic outdoor unit under 1.5 cubic metres (0.6 for a flat), not on a pitched roof and not on a front wall facing the road, falls within permitted development following the 2025 rule change. Listed buildings and conservation areas are the exceptions, and leaseholders need the freeholder's consent. We tell you at the survey if your property is one of the exceptions.
How much does air conditioning cost to run?
Less than most people expect. A typical single-room unit draws around 0.5 to 1 kW while running, so an evening of cooling costs a few tens of pence at current tariffs, and in heating mode it is usually cheaper per unit of heat than a plug-in electric heater. Keeping the filters clean and having the system serviced keeps it at that level.
Are you F-Gas registered?
Yes. Vantage is F-Gas certified through Refcom, registration REF1024550, which is a legal requirement for anyone installing or working on air conditioning refrigerant circuits. Every installation is commissioned, leak-tested and comes with a 12 month labour guarantee on top of the manufacturer warranty.
