What you can do yourself, and what needs us
Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and ring 07833 053749, or email if that’s easier.
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo of the display helps even more.

London homes in Penge can be short of outside space, so the outdoor unit may end up on a rear wall, a flat roof or a balcony. We look at noise towards neighbours and windows as well as looks, and the pipe run is planned to be short, neat and out of the way.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Air conditioning in Penge: local notes
The Valuation Office Agency’s council tax figures put about 47% of homes in and around Penge before 1919, and about 66% of households live in flats, according to the 2021 Census. Older properties often mean solid walls and period details, so pipe runs are planned to stay neat and out of sight. In flats, the lease and the freeholder typically decide where an outdoor unit can go, and the permitted development rules for flats are tighter. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.
If you work from home near Penge West station, a home office that overheats is one of the easiest rooms to cool. Homes near Church of St John the Evangelist are a good example of where we look up the heritage status of the building before fixing anything to it.
Penge is about 1 mile west of Beckenham, in Greater London. Wherever you are in the SE20 postcode area, our engineers can take on air conditioning. Count every place we list in Greater London and you reach 764, with Penge on the list.

Why it’s worth doing now in Penge
New systems now use lower-impact refrigerants. From 2025, single splits under 3 kg cannot use refrigerants with a GWP over 750, which is why R32, with a GWP of 675, is now common. R410A, used in many older systems, has a GWP of 2088. In a London building, getting the freeholder’s or agent’s agreement can take a while, so it’s worth starting early.
The cost depends on the system and the number of rooms or units, how easy the units are to reach and the parts and time the job needs. We give you a fixed price before we start, so there are no surprises.

What affects the cost of air conditioning
The diagnosis comes before the price. We look at:
- One-off work versus a regular service cycle
- The equipment or parts the job needs
- What electrical work the job needs
Several rooms, units or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed price.
Asking for a quote
Good photos often save a visit. The most useful are:
- Your installation or service records
- The make and model of the system, from the label
- Where the property is and what kind of building it is
The quickest way to a quote is to send pictures: 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 simple jobs can often be priced without a visit.
Your questions about air conditioning in Penge
Is Penge in your area for air conditioning?
Yes. Penge is one of the places we cover. Just call us on 07833 053749 or send an email with a few details.
Do I need permission to put air conditioning in my flat in Penge?
In many cases, yes, once the lease and the building’s rules are checked. 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.
Where will you put the outdoor unit?
The position is agreed on the survey, not on the day. It needs space around it to breathe and room for an engineer to service it, and walls or roofs facing a road can raise planning questions. We explain the options and any permissions to check.
Which type of system should I choose?
There’s no single best type. A split suits one room, a multi-split several, a ducted system hides the unit, and a cassette spreads air across larger rooms. The survey ends with a recommendation and the reasons.
What warranty do I get?
Warranty is the manufacturer’s own, on its terms. Terms differ by brand, and we set them out on your quote.
Does air conditioning work as heating?
In most cases, yes. A heat pump moves heat from the outside air into the room, so it gives out more heat than the electricity it uses. To replace your main heating, there are extra conditions, including for the £2,500 Boiler Upgrade Scheme grant for air-to-air heat pumps.
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 recorded and F-Gas records kept where they apply.
How it works
We book the visit for a day and time that suit 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. From there, the work takes a day or more, depending on the number of rooms, the pipe routes and the access. A note on parking and access helps us plan a visit to Penge.
- You send photos, or we visit and survey the rooms and outside.
- Output, positions and price are settled before anything is booked.
- On the day, dust sheets go down and the indoor and outdoor units are fitted.
- Connections are made, checked for leaks and pulled down to a vacuum.
- It’s switched on, checked and handed over with its records.
Getting ready for the visit
- Mention any parking restrictions near the property
- Clear access to the fuse board
- Give us access to the outside wall, roof or yard where the outdoor unit sits
