How air conditioning works in SM5
We fit wall-mounted splits, multi-split systems, ducted systems and ceiling cassettes, with VRF for larger buildings. The right choice depends on the rooms, the building and how visible you want the indoor units to be and we talk you through it on the survey. The work covers VRF systems, multi-split systems and ceiling cassettes, and the jobs we see most are a system on old refrigerant that’s due for replacement and a business premises that overheats in summer.
We book the visit for a day and time that suit you, and we keep you posted if anything changes. On arrival, the engineer compares the job with the survey, your photos or the details you gave us. If something is different, we talk it through with you before carrying on. After that, it takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer.
- You send pictures, or we visit and survey the rooms and outside.
- Each room is sized and the unit positions agreed, then you get a fixed-price quote.
- We protect the area, then fit both halves of the system.
- We run and connect the pipes, cable and drain, then pressure test and evacuate the circuit.
- We commission, show you the controls and leave the F-Gas and warranty paperwork.
What affects the price in SM5
Height, access and the distance between the indoor and outdoor units can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.

Air conditioning across SM5: local notes
In SM5, as across England, the same permitted development rules apply: cooling-only units are not covered, listed buildings need consent and conservation areas restrict outdoor units facing a road.
Across London and the South East, we reply to enquiries the same working day, and our emergency line is open 24/7.
Carshalton: Living close to Church of All Saints? Some older properties in parts like that are protected, and the survey finds out whether yours is. Close to Carshalton station? A small study or box room used for work can typically be cooled with a single indoor unit.
What we’re called out for in SM5
Poor sleep is one of the most common reasons homeowners ask about air conditioning. Once a bedroom has soaked up heat during the day, opening a window may not bring the temperature down far enough, particularly when there’s no breeze.
Keep an eye out for these signs:
- A loft room or top floor that bakes in summer
- An old system that needs replacing
- Bedrooms and offices that overheat in summer
- Rooms heated by plug-in heaters
What owners can safely do
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.
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and phone us on 07833 053749 or use the quote form.
Aftercare tips
A little care keeps the system in better shape. We recommend:
- Flag any change in how the system sounds or performs
- Leave space around the outdoor unit
- Choose a comfortable set temperature rather than the lowest
- Close windows and doors while the system is cooling
Commissioning is the last stage: every mode is tested before we go. We check it’s running as the manufacturer intends, then show you the controls and the timer, so you are confident using it.
Give the outdoor unit room to breathe. Leaves, plants, bins and stored items around it restrict the airflow, which makes the whole system less efficient.
What affects the quote in SM5
Jobs vary more than people expect. What affects the quote:
- Whether it’s a one-off job or part of a maintenance contract
- The number of rooms, units or zones
- The equipment or parts the job needs
- The condition of any existing system
No two properties are the same, so we price each one individually. The system, the access, the pipe routes and the parts involved all play a part.
What we need to know
To help us quote quickly, send us:
- A photo of the consumer unit with the cover closed
- Your installation or service records
- Wide photos of the room or the existing unit
- The outside wall, roof or yard where the outdoor unit sits or would go
Every quote starts with a look at the job, from a site survey or, where the job is straightforward, from pictures and measurements. After that, we send a fixed price so you know the cost before we begin.
Questions from SM5
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in SM5 and across Greater London. Tell us who should receive the paperwork.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for problems that can’t wait for a planned visit. Call 07833 053749 and tell us what’s happened.
Where does the outdoor unit go?
The position is agreed on the survey, not on the day. It must have clear airflow and space for servicing, and walls or roofs facing a road can raise planning questions. We’ll tell you what to check before we fit it.
Do I need planning permission?
Not always. On a house, air-to-water heat pumps and, since 2025, air-to-air systems that heat as well as cool can be permitted development if they meet the conditions. Permission is more likely to come up for cooling-only units, listed buildings, flats and road-facing positions in conservation areas and the survey picks it up. This is general information, not legal advice.
Will you make a mess?
We start with protection: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
Why use an F-Gas certified company?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before you book anyone, and we are happy to show ours.
When will I hear back?
On the same working day you contact us. Then we agree a date that works for you, with a fixed price before work starts.
