Welling air conditioning
Air conditioning across Welling and nearby, from the first look to the final check and a fixed price agreed before we start.
- A system on old refrigerant that is due for replacement
- Commercial rooms that are too warm for staff
- A loft room or top floor that bakes in summer
Air conditioning in Welling, done properly
We install leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. We recommend a model on the survey and explain why it suits the room, along with the manufacturer’s warranty terms on your quote. Modern air conditioning heats as well as cools: in heating mode they work as an air-to-air heat pump, so a system bought for summer earns its keep in winter too.
Many installs in Welling can go ahead as permitted development, but listed buildings, conservation areas and flats need more care: we flag that at the survey.
Across London, and in Welling too, a lot of air conditioning goes into flats and terraces rather than detached houses. So the first questions are where the outdoor unit can sit, how the pipes get to it and whose permission is needed. In a flat, the lease and the freeholder usually come into it, and we can give you the details they’ll ask for.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. That also helps where the warranty terms ask for regular servicing.

Welling questions
Can you do air conditioning in Welling?
We do: Welling falls inside our working area. Get in touch with the details and we reply the same working day.
Do I need permission to put air conditioning in my flat in Welling?
Often, yes, but the lease and the freeholder usually have a say. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Which type of system should I choose?
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. The survey ends with a recommendation and the reasons.
Do I need a new electrical circuit?
Most systems need their own supply from the consumer unit. 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.
Why use an F-Gas certified company?
Certification shows a business is approved to work on systems that hold F gas refrigerant. That is not optional: it’s required by law, and we hold it.
Can I do the refrigerant work myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
How does the warranty work?
Warranty is the manufacturer’s own, on its terms. Terms differ by brand, and we set them out on your quote.
Fixed-price quotes for air conditioning in Welling
Your quote is based on your property. We consider:
- Whether we need access equipment for high-level work
- The brand, model and parts involved
- How far the pipework has to run, and where
The cost depends on the system and the number of rooms or units, the access and what the work involves. You get a fixed price before we start, so you know where you stand.
What we need to know
A few details help us quote accurately. With your enquiry, please include:
- The paperwork from the last service, if you have it
- A photo of the consumer unit with the cover closed
- The outside wall, roof or yard where the outdoor unit sits or would go
Getting a quote is straightforward. Send a few details and pictures, and we reply the same working day. If we need to see the property first, we book a survey at a time that works for you.
Keeping the system healthy
Simple habits make a real difference. Our advice:
- Refit filters properly after cleaning
- Keep the room closed while it runs
- Choose a comfortable set temperature rather than the lowest
Questions after the installation go to the same number. Tell us what the system is doing, and any code on the display and we will help you sort it out.
Book an annual service. A service cleans what you can’t reach and picks up faults before they stop the system and keeps the warranty paperwork right where servicing is a condition.
Different systems, different jobs
Offices, shops and commercial rooms
Systems over 12 kW of effective rated output bring extra duties for the building, including a TM44 inspection by an accredited energy assessor at least every 5 years. We can arrange the inspection and get the system ready for it.
Ducted systems
Ducted units can feed several rooms through a network of ducts, which suits new builds, extensions and refurbishments where ceilings are open.
What we do, step by step
Think of the visit in three stages: look, put right and sign off. First we check the system or the space against the plan, then the work itself, and finally we test, record and explain. Most of the time goes on the middle part, which takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. For a job in Welling, tell us about parking, permits and access to the building when you get in touch.
- First the diagnosis: a survey of the rooms, the walls, the outside and the electrics.
- Next, a recommendation for each room and a fixed price.
- Then the work: units up, pipes and drain run, and a new circuit where needed.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
How to prepare
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Make sure we can reach the consumer unit or fuse board

Air conditioning around Welling
VOA council tax data show about 75% of homes in the Welling area date from 1919 to 1939, and about 71% of households live in detached or semi-detached houses, according to the 2021 Census. We check the wall construction on homes of that age, as it decides how the pipework goes through. Houses typically have a side or rear wall with room for the outdoor unit, and a multi-split can serve several rooms from one outdoor unit. In London, outdoor unit positions, building rules and access tend to need more planning than the install itself.
Danson House (roughly 0.4 miles south-east) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on. If you commute from Welling station and work from home on other days, one wall-mounted unit in the home office is often all that’s needed.
