Most overheating comes from heat gained through the day. Sun through large windows, roof lights and glazed doors is the biggest source in many rooms, and the heat lingers long after the sun has moved round.
Customers normally contact us when they notice something like this:
- Too many options and no clear advice
- Fans and portables that don’t keep up
- A business premises that overheats in summer
If your home is in one of the older streets near Church of St John the Evangelist, it’s worth checking whether it’s listed or in a conservation area before an install.
Before booking anyone

What else we do in Old Coulsdon
Pricing air conditioning in Old Coulsdon
Before we fix a price, we need to know a few things. We check:
- A single visit or a regular plan
- Which make and model is being fitted or worked on
- Access, including height, roofs and ladders
A single unit or a whole estate, we price it on the same basis: what needs doing, how we get to it and what it needs. The price is fixed before we start, and the quote sets out the VAT.
What to send for a quote
Photos and a few facts are often enough to price a simple job. Useful things to send:
- A close-up of the unit’s label showing the model number
- The outside wall, roof or yard where the outdoor unit sits or would go
- Photos showing the indoor unit and the space around it
Getting a quote is straightforward. Call or email with a few details and we will come back to you the same working day. Where a survey is needed, we arrange a time that suits you.
Your questions about air conditioning in Old Coulsdon
Do you cover Old Coulsdon for air conditioning?
Yes. Old Coulsdon is one of the places we cover. Get in touch with the details and we reply the same working day.
Is air conditioning in Old Coulsdon permitted development?
The answer turns on the property and where the outdoor unit would sit. The half-mile around the middle of Old Coulsdon holds about 6 listed buildings and structures. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask Croydon council, which is usually the planning authority for Old Coulsdon.
Should I choose wall-mounted, ducted or cassette?
There’s no single best type. Wall-mounted splits suit single rooms, multi-splits run several rooms from one outdoor unit, ducted systems hide the unit in the ceiling, and cassettes suit offices and larger rooms. We recommend one on the survey and explain why.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used, and we’ll suggest a schedule with a fixed price. Leak checks required by the F-gas rules can be built in for larger systems.
What accreditations do you have?
As the law requires for refrigerant work, we are an F-Gas certified company. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Do you look at the job first?
Yes, always. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need, and the quote is based on that.
Whose job is it to check the system for leaks?
Responsibility is shared between the operator, typically whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
How the visit works
The visit goes in the diary at a time that works for you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, it takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. If your building in Old Coulsdon has a managing agent, a concierge or sign-in rules, mention them when you book.
- We start by looking at the rooms, the walls and where the outdoor unit can go.
- You receive one fixed figure covering the kit, the fitting and the positions we agreed.
- The indoor unit is fixed in place, the outside unit positioned, and the connecting runs put in tidily.
- Power is wired in, the joints are proved leak-tight under pressure and a vacuum pump draws out air and moisture.
- We commission the system, show you the controls and leave the F-Gas records and the manufacturer’s warranty details.
Preparing for the visit
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Let us know where we can park and unload
- Dig out any previous service or F-Gas records

Air conditioning around Old Coulsdon
The Valuation Office Agency’s council tax figures date about 47% of homes in and around Old Coulsdon to the post-war years, 1945 to 1972, and the 2021 Census found about 76% of households in detached or semi-detached houses. Homes of that age normally have cavity or solid brick walls, and we check which before planning the pipe route. 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. In London, outdoor unit positions, building rules and access tend to need more planning than the install itself.
With historic houses such as Addington Palace about 5 miles north-east, it’s a reminder that older homes nearby may be listed, which changes the planning rules.
