How we handle air conditioning in Colden Common

Single-room systems are typically £1,200–£2,200 + VAT, two rooms on a multi-split £2,800–£4,500 + VAT, and three to five rooms £4,500–£8,500 + VAT. Those ranges include supply, installation, commissioning and F-Gas documentation, with commercial and VRF systems priced after a survey. Air con, air conditioning, a split system: whatever you call it, in Colden Common 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.

In a smaller place like Colden Common, most installs are in houses and cottages, often with gardens, which normally leaves room for an outdoor unit. The wall type and how the electrics reach the unit are often the main things to check.

Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

The process

Our engineers arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. On site, it takes anything from a day for one room to several days for a multi-room or ducted system. Around Colden Common, access is normally simple, though gates and garden access are worth mentioning.

  1. We survey the rooms and the outside of the property, or work from photos and details for simple jobs.
  2. You receive one fixed figure covering the kit, the fitting and the positions we agreed.
  3. Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
  4. The electrical supply is connected, and the refrigerant circuit is pressure tested and evacuated.
  5. Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.

How to prepare

  • Move furniture away from the wall where we’ll be working
  • Make sure someone can let us in at the agreed time
  • Keep pets and children away from the work area

Ask for a quote

Every quote starts with a look at the job, from a site survey or, where the job is straightforward, from photos and measurements. Then you get a fixed price so you know the cost before we begin.

Advice

Honest limits

To be straight with you, there are a few things this work won’t fix:

  • Central heating repairs
  • Work that needs permission from a landlord or the council
  • Building damp that has a structural cause

If you are not sure, just call 07833 053749 or fill in the contact form and we will give you a straight answer.

Where we work

  • Ducted systems
  • VRF systems
  • Ceiling cassettes
  • Wall-mounted split systems
  • Multi-split systems
  • Air-to-air heat pumps

System by system

Ceiling cassettes

Cassettes are good at even airflow across a large floor area with just a grille visible in the ceiling.

Offices, shops and commercial rooms

Systems over 12 kW of effective rated output bring extra duties for the building, such as a TM44 inspection by an accredited energy assessor at least every 5 years. We can arrange and prepare for it.

Keeping the system healthy

Aftercare is straightforward, and it makes the next visit easier:

  • Have the system serviced once a year
  • Use moderate settings for comfort and economy
  • File the paperwork with the manual

The filters are the one part you’ll look after yourself, so we show you how. Clean them every few weeks when the system is in heavy use, following the manual, and keep space clear around the outdoor unit.

Do not ignore small changes. A drip, a noise or a flashing light is often an early sign of a fault, and early repairs are normally simpler.

Air conditioning in Colden Common: local notes

About 72% of households live in detached or semi-detached houses, according to the last census (2021). With homes like that, finding a sensible outdoor unit position is rarely hard, and a multi-split lets two or more rooms run off it.

About 4.8 miles south-west stands South Stoneham House. Listed homes in any area need consent first, so tell us if yours is one. Around Church of the Holy Trinity, a quick check of the listing and conservation maps is part of planning any install.

Colden Common is about 2 miles north-east of Eastleigh, in Hampshire. Anywhere in SO21, we cover air conditioning. Our Hampshire coverage runs to 683 places, and Colden Common is one of them. Guildford, roughly 37 miles off, has its own page on this site.

Our engineers cover all of SO21 and SO50 and the roads nearby. Local streets include St Vigor Way, Ash Close and Birch Close, and we cover them all. Close to Colden Common, our area also takes in Brambridge (1 mile south-west), Nob's Crook (1 mile south-east), Lord's Wood (1 mile south-west), Highbridge (1 mile south-west) and Fisher's Pond (1 mile south-east). Further out, we also cover Winchester (4 miles north), Gosport (15 miles south-east), Fareham (11 miles south-east) and Horndean (15 miles south-east).

Colden Common questions

Do you cover smaller places like Colden Common?

Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.

Is air conditioning in Colden Common permitted development?

That depends on the building and where the outdoor unit goes. Around 10 listed entries sit within 0.5 miles of central Colden Common. 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 Winchester City council, which is typically the planning authority for Colden Common when it matters.

How do I know what size unit to get?

Sizing is done on the survey, room by room. An undersized unit never catches up, and an oversized one cycles and wastes energy, so we explain why we’ve chosen a particular output.

Why does F-Gas certification matter?

F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. In Great Britain, that certification is a legal requirement, not an optional extra, and AirCon Doctor is certified.

Which accreditations do you hold?

As the law requires for refrigerant work, we’re an F-Gas certified company. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.

Does air conditioning work as heating?

Yes, most modern split systems run as heat pumps, so they can heat a room in winter. The Energy Saving Trust points out that an air-to-air heat pump is often just called air conditioning. We confirm the heating function of the model we quote.

Will you need to do electrical work?

Usually, yes. The fuse board is checked on the survey, and any electrical work goes on the quote and we install and certify the circuit as NICEIC approved contractors.

A customer’s words

“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.”
