What happens if it’s left?
Putting up with another summer of portable units and fans rarely makes sense. A properly installed split moves heat outside, keeps the noisy parts out of the room and most of the time heats too, so it works for you in winter as well. Hot weather is when everyone in London wants air conditioning, so it’s easier to plan the work in Carshalton early.
Homes, offices, shops and public buildings are all priced the same way: what’s needed, how we reach it, the parts and the labour. Call for a fixed-price quote and we will explain each part.

About our air conditioning in Carshalton
Good air conditioning starts with the right system in the right place. We look at each room’s size, glazing, orientation and use, and we agree the unit positions and the route for the pipes, cable and drain before you get a fixed-price quote. For air conditioning in Carshalton, one call covers the survey, the fixed-price quote, the installation and the F-Gas paperwork.
A single room takes a day in most homes, with multi-room systems taking longer depending on pipe routes, and we leave the room clean and the controls explained.
Space outside is often tight in Carshalton, as in much of London, which means a rear wall bracket, a flat roof or a balcony is often the best spot for the outdoor unit. We look at noise towards neighbours and windows as well as looks, and we plan the pipe route so it’s as short and tidy as the building allows.
Think of the paperwork as the system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

Offices, shops and commercial rooms
Larger buildings may suit VRF, which runs many indoor units from shared outdoor units. Commercial and VRF systems are priced after a survey and the quote sets out the design.
Pipework and condensate drains
Air conditioning takes moisture out of the air when it cools, and the condensate drain carries it away. Where it cannot fall naturally to a drain, a condensate pump lifts it, and we plan that on the survey.
After we have gone
Aftercare is straightforward, and it helps at the next service:
- Let filters dry fully before you put them back
- Close windows and doors while the system is cooling
- Clean the filters every few weeks when the system is in heavy use
Before we leave, the system is commissioned and tested in each mode. Once it’s running properly, we take you through the controls and settings so you know how to get the best from it.
Don’t ignore small changes. A drip, a noise or a flashing light is often an early sign of a fault and catching it early keeps the repair small.
Air conditioning in Carshalton: the local picture
The Valuation Office Agency’s council tax figures show about 39% of homes in and around Carshalton date from 1919 to 1939. Homes of that age normally have cavity or solid brick walls, and we check which before planning the pipe route. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.
If you commute from Carshalton station and work from home on other days, one wall-mounted unit in the home office is often all that is needed. Nonsuch Mansion (roughly 2.7 miles west) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.
Carshalton is about 4 miles south-east of Wimbledon, in Greater London. Wherever you are in the SM5 postcode area, we can help with air conditioning. In Greater London alone we list 764 places and Carshalton is among them.

What happens on the day
The first job on site is protection: sheets over the floor and any furniture nearby and nothing is moved without asking you. After that, anything electrical is made safe and we start. The work on site takes anything from a day for one room to several days for a multi-room or ducted system, and we tidy up before we leave. Parking bays, permits and roof or balcony access are the first things we ask about in Carshalton.
- We survey the rooms and the outside of the property, or work from photos and details for simple jobs.
- You receive one fixed figure covering the kit, the fitting and the positions we agreed.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- We connect the supply, pressure test the pipework and evacuate it before the refrigerant is released.
- The system is commissioned and checked in every mode, and we hand over the controls, F-Gas records and warranty information.
Preparing for the visit
- Make sure we can reach the outdoor unit, or where it will go
- Have the make and model of any existing unit to hand
- Clear access to the fuse board
Getting a price
The quickest way to a quote is to send photos: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and many jobs can be priced from that.

Your questions about air conditioning in Carshalton
Do you cover Carshalton for air conditioning?
Yes. Carshalton is one of the places we cover. Get in touch with the details and we reply the same working day.
Can I have air conditioning in a flat in Carshalton?
Often, yes, but the lease and the freeholder normally have a say. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Can air conditioning heat my home as well?
Normally, yes. Running as a heat pump, it moves heat in from outside rather than making it from electricity alone. To replace your main heating, there are extra conditions, including for the £2,500 Boiler Upgrade Scheme grant for air-to-air heat pumps.
Can I do the refrigerant work myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
What accreditations do you have?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. We are also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
How long does air conditioning installation take?
Most single-room systems take a day. Multi-split, ducted and cassette systems take longer, and we tell you how long on the quote.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule with a fixed price. Leak checks required by the F-gas rules can be built in for larger systems.
