Wall-mounted air conditioning unit above the bed in a Surrey home
A wall-mounted split in the main bedroom is the most common job we fit in Guildford.

Most people looking for air conditioning — or aircon — in Guildford want one of three things: a bedroom they can actually sleep in during a heatwave, a loft conversion that isn't unbearable from June to September, or a living room or kitchen-diner with big glass doors that turns into a greenhouse every afternoon. All three are straightforward jobs for a wall-mounted split system.

Tell us which rooms you want cooled and we'll arrange a free survey. We measure each room properly — glazing, orientation, insulation and how it's used — check where the outdoor unit can go, and give you one fixed written price covering everything. No day rates, and nothing added on the day.

What we install in Guildford homes

Most of what we fit is a split system: an indoor unit on the wall, a compact outdoor unit outside, and a small refrigerant pipe between them through one core-drilled hole. Almost every modern split is an air-to-air heat pump, so it heats in winter as well as cooling in summer.

  • Bedroom air conditioning. Usually a 2.5kW wall-mounted unit. The quietest models, such as the Daikin Perfera, run at around 19 dB(A) on their lowest setting — quieter than a whisper.
  • Living rooms and kitchen-diners. Typically 3.5kW to 5kW, sized for the room's real heat load, which large south- or west-facing glazing pushes up.
  • Loft conversions. Rooms under the roof gain heat fast and usually need a bigger unit than their floor area suggests. Air conditioning in a loft conversion is one of the most common requests we get in Guildford's terraces and semis.
  • Conservatories and garden rooms. Glass rooms need more capacity than their size suggests, and a heat pump makes them usable in winter too.
  • Several rooms. A multi-split runs two to five indoor units from one outdoor unit — cheaper overall than separate systems and only one unit on the wall outside.

We fit leading brands including Daikin, Mitsubishi Electric and Fujitsu. Read more about air conditioning installation or how an air-to-air heat pump heats a room.

What air conditioning costs in Guildford

Typical installed prices, supplied and fitted including VAT:

  • One room: £1,800 to £2,600 for a 2.5kW split, or £2,200 to £3,000 for a 3.5kW.
  • One large room: £2,600 to £3,700 for a 5kW unit.
  • Two rooms on a multi-split: £3,500 to £5,000.
  • Three rooms: £4,800 to £6,500.

The things that move a Guildford price are pipe run length, where the outdoor unit can go, whether the walls are solid or cavity, and any new electrical work. We check all of them at the survey and include them in one fixed written figure. Our air conditioning installation cost guide breaks the full range down, including the extras to look for on any quote.

Guildford's homes, and what they mean for an installation

The town centre and older streets

Guildford Borough Council looks after around 40 conservation areas, including the town centre and Charlotteville and Warren Road. Many of the houses on the streets climbing away from the High Street are Victorian or Edwardian with solid walls, which take longer to core-drill than a modern cavity wall, and owners often want the pipework hidden. Where the outdoor unit would be visible from the road, we plan its position at the survey — usually on a rear or side wall, out of sight.

Merrow, Burpham, Stoughton and Onslow Village

The interwar and post-war suburbs are usually the simplest installations in Guildford: cavity walls, a back garden or side return for the outdoor unit, and short pipe runs. A bedroom or living room here is typically a one-day job.

Flats and newer developments

Apartments near the station and in the newer developments behave like London flats. The outdoor unit usually needs the freeholder's or managing agent's consent, and a balcony or flat-roof position may need access equipment. We bring the details the managing agent will ask for to the survey.

The Surrey Hills villages

Shere, Gomshall, Albury, Compton and Peper Harrow sit in or beside the Surrey Hills National Landscape, with plenty of period and listed cottages. Domestic air conditioning installation here is mostly about discretion: a low-profile outdoor unit tucked out of view, and pipework run neatly or concealed where the wall allows.

Not sure your home is suitable? Most are — a free survey will tell you.

Planning permission in Guildford

For most Guildford houses, the outdoor unit falls under permitted development if it meets the conditions on size, position and noise at the boundary. The Planning Portal's guidance on air conditioning sets those conditions out. Listed buildings and conservation areas are the common exceptions, and Guildford has a lot of both. We check which applies to your home at the survey, before any equipment is ordered, and help with the paperwork if consent is needed.

Air conditioning servicing and repair in Guildford

Air conditioning maintenance matters as much as the installation. An annual service — around £90 for a single split system — cleans the filters and coils, checks the refrigerant and electrics, and keeps the manufacturer warranty valid. We service and repair all the major brands, including systems another company installed. Guildford is the furthest west we travel regularly, so for a breakdown we'll tell you honestly how soon we can get there.

Why Guildford homeowners choose Kelvara

We survey before we price. A figure given over the phone without seeing the property is a guess, and guesses get revised upwards once the engineer arrives.

One fixed written price. Equipment, labour, materials, electrical work, commissioning and making good, in one figure agreed before we start.

F-Gas qualified engineers. Anyone handling refrigerant legally needs to be. It's worth checking with any air conditioning installer you're considering.

Questions

Air conditioning in Guildford — common questions

How much does air conditioning installation cost in Guildford?

Roughly £1,800 to £2,600 for a single-room split system supplied and fitted, £3,500 to £5,000 for two rooms on a multi-split, and £4,800 to £6,500 for three. Larger rooms need a bigger unit and cost more. After a free survey we give you one fixed written price, so what you are quoted is what you pay.

Do I need planning permission for air conditioning in Guildford?

For most houses, no — the outdoor unit usually falls under permitted development if it meets the conditions on size, siting and noise. Guildford has around 40 conservation areas, including the town centre, and listed buildings are common in the older streets and villages. In those, an outdoor unit visible from the road may need consent from Guildford Borough Council. We check this at the survey, before anything is ordered.

Which villages around Guildford do you cover?

All of them within the borough and its edges, including Shalford, Bramley, Wonersh, Chilworth, Albury, Shere, Gomshall, Compton, Puttenham, Peper Harrow, Worplesdon, Jacob's Well, Send and Ripley. If you're not sure whether we cover your address, ask.

Can air conditioning heat my Guildford home in winter?

Yes. Almost every modern split system is an air-to-air heat pump, so it heats as well as cools — and does so far more efficiently than electric heaters. It's a popular choice for loft conversions, extensions and garden rooms that the central heating doesn't reach properly.

Do you service and repair air conditioning in Guildford?

Yes, including systems another company installed. An annual service starts at around £90 for a single split system and keeps the manufacturer warranty valid. For breakdowns, Guildford is the furthest west we travel regularly, so we'll tell you honestly on the phone how soon we can get there.
