Air conditioning replacement is removing an old system — often one using R22 or R410A refrigerant — and installing new, more efficient equipment, re-using pipework where it is safe and compatible.

Guildford and surrounding areas

Guildford supports a mix of high-street retail, professional offices, hospitality and light industry. Woking is about 9 km away.

That includes premises in GU1 and the surrounding districts. Nearby, we also cover Godalming (about 6 km), Woking (about 9 km) and Aldershot (about 13 km). In Guildford we work with offices, shops and hospitality premises, from a single room to a whole floor; each job starts with a heat load check rather than a guess from the floor area.

What the job covers

  • Condition survey of the existing system
  • Pipework re-use assessment, flushing where suitable
  • Removal and disposal of old equipment
  • Installation of new efficient units
  • Commissioning and new F-gas records

How a job in Guildford works

  1. Survey

    We record what is installed, its condition and refrigerant, and what can be re-used. For sites in Guildford we confirm access and parking beforehand.

  2. Plan the swap

    Removal and installation are scheduled to keep downtime short.

  3. Recover and remove

    Refrigerant is recovered into certified cylinders and the old units removed.

  4. Install and commission

    New units are fitted, tested and commissioned with fresh records.

Before you book in Guildford

Pipe re-use

Re-use depends on pipe size, condition, cleanliness and the new refrigerant. We test before relying on it.

Neighbours and noise

Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.

R22

Since 1 January 2015, R22 systems cannot be maintained using virgin or recycled R22. If one leaks, the practical fix is usually replacement.

Leased premises

If your Guildford premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.

Typical premises in Guildford

  • Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
  • Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
  • Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
  • Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.

In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.

Questions about replacement and upgrades in Guildford

How much does it cost to replace air conditioning in Guildford?

Guide prices in Guildford run from about £1,895 to £5,095 per indoor unit, plus VAT. A typical job (replacing a 3–4 unit system, re-using sound pipework) costs £6,850–£16,695 plus VAT. We fix the price in writing after a free survey.

Do you also cover Godalming, Woking and Aldershot?

Yes. Alongside Guildford, we also cover Godalming, Woking and Aldershot. Each has its own page with local guide prices.

Which postcodes do you cover in Guildford?

All of them, including GU1. Give us your postcode when you enquire and we will confirm the visit details.

Will a new system be cheaper to run?

Usually. Modern inverter systems are considerably more efficient than equipment from 15–20 years ago, though savings depend on use.

Should we replace R410A systems now?

Not necessarily. If an R410A system is working well and maintained, keep it. Plan replacement when it becomes unreliable or expensive to run.
