Air conditioning for Farnham

How it works

Each visit follows the same order: check the plan with you, put the dust sheets down, carry out the job, test what we’ve done and talk you through it. On site, the work takes a day or more, depending on the number of rooms, the pipe routes and the access. Most visits to homes in Farnham are booked for a weekday, with businesses fitted around trading.

  1. We survey the rooms and the outside of the property, or work from photos and details for simple jobs.
  2. Cooling loads are worked out room by room, and the written price names the make, the model and every position.
  3. The units go up and the pipework, cable and condensate drain are run neatly between them.
  4. The electrical supply is connected, and the refrigerant circuit is pressure tested and evacuated.
  5. The system is commissioned and checked in every mode, and we hand over the controls, F-Gas records and warranty information.

Getting ready for the visit

  • Clear the space around the indoor unit, or where it will go
  • Keep pets and children away from the work area
  • Have the make and model of any existing unit to hand

Ask for a quote

Some jobs can be priced from photos, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, the quote is fixed before anything goes ahead.

Advice

Air conditioning for homes and businesses in Farnham

Most modern split systems run as heat pumps, so they can heat as well as cool. The Energy Saving Trust recognises that air-to-air heat pumps often go by the name air conditioning, and a well-chosen system can earn its keep all year round. Most enquiries from Farnham start with one hot room: a bedroom, a home office or a loft conversion. That’s typically a single wall-mounted split, from £1,200 + VAT.

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.

Farnham has a mix of older and newer homes, and the walls decide a lot about the install. Older solid walls need more drilling than modern cavity walls, and a loft or a void can hide a pipe run that would otherwise be on show.

Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

FAQs for Farnham

Do you cover Farnham for air conditioning?

Yes. We work across London and the South East from our base in East Grinstead, and Farnham is part of that. Tell us a little about the job and we will take it from there.

Will air conditioning in Farnham need planning permission?

There’s no single answer: the building and the outdoor unit position decide it. The Farnham Conservation Area is close to the centre of Farnham. 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 the local planning authority (for Farnham, usually Waverley council) when it matters.

Do you offer maintenance contracts?

Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up and F-Gas records kept where they apply.

How soon will you get back to me?

You’ll hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.

Which accreditations do you hold?

AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re also Checkatrade members.

Will you need to do electrical work?

Most of the time, yes: a dedicated circuit is needed. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and as NICEIC approved contractors we install and certify it as part of the job.

What does F-Gas certified mean?

Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before booking anyone, and we are happy to show ours.

Common problems we fix in Farnham

In shops, offices and restaurants, the heat comes from customers, staff, equipment and lighting as well as the sun. Comfortable staff and customers are the usual reason businesses get in touch, along with keeping equipment rooms at a steady temperature.

Common reasons people call us include:

  • Working from home in a room that gets too warm
  • An office, shop or restaurant that is uncomfortable for staff and customers
  • An ageing air conditioning system near the end of its life

Plenty of people near Farnham station split the week between the train and a spare room, and that spare room is often the first to get a unit.

Questions to ask before you book

What affects the quote in Farnham

We quote each job individually. This is what makes a difference:

  • Whether we need access equipment for high-level work
  • The distance and route between the indoor and outdoor units
  • The size of the job

No two properties are the same, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all make a difference.

Asking for a quote

Photos let us diagnose from a distance. Try to include:

  • The address and the type of property
  • The make and model of the system, from the label
  • Your installation or service records

Our prices page gives typical ranges, but your quote is based on your job, because no two buildings, rooms or systems are the same. Once we’ve looked at the job, from photos or on a survey, you get a fixed price. To start, give us a ring on 07833 053749 or email us.

Safe owner checks

Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.

Owners can handle the everyday basics: 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.

Air conditioning in Farnham: the local picture

About 63% 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.

If your home is in one of the older streets near St Joan of Arc's Church, it’s worth checking whether it’s listed or in a conservation area before an install.

A recent job in Farnham

Castle Street, Farnham (GU9)

Property
A grade ii listed townhouse used as a law firm.
Work carried out
Installation of a Fujitsu multi-split system serving three offices and a client meeting room. The listed building setting required a pre-application planning discussion with Waverley Borough Council, which confirmed the outdoor unit could be positioned in the rear garden. All external fixings and pipework were sympathetically finished.
Outcome
The conservation officer confirmed the installation was acceptable and the firm reported that the meeting room in particular: previously used for client meetings in all weather: was now comfortable throughout the summer, improving client impressions significantly.
