Air conditioning repairs in Custom House: local notes
About 64% of homes in Custom House and the neighbourhoods around it have been built since 2000, according to Valuation Office Agency council tax records, and about 76% of households live in flats, according to the last census (2021). Balcony, roof or high wall? Knowing where a flat’s outdoor unit is helps us bring the right access kit. London repairs often depend on reaching the outdoor unit, so access details help us plan. About 5 listed entries lie within half a mile of central Custom House, Warehouse K (grade II) among them. We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that.
Near Custom House station, as anywhere, a photo of the error code on the controller is the quickest way to start a repair.

Air conditioning repair in Custom House, done properly
Any repair we carry out in Custom House starts the same way: the engineer reads the fault codes and checks the electrics, the airflow, the condensate drain and the refrigerant pressures and temperatures. After that, you get a plain explanation and a fixed price for the repair. We are often asked to deal with a suspected refrigerant leak and a noisy indoor or outdoor unit, on multi-split systems, ducted systems and heat pumps.
In a managed building in Custom House, the repair may need booking through the agent or building manager, so tell us who controls access. Outdoor units on roofs may need a key, a permit or an escort, and we plan for that before we arrive.
Warranty periods vary by brand and by product. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

Common questions in Custom House
How do I get a quote for air conditioning repair in Custom House?
Start with a short message: the address, what you need and a picture or two. Where pictures are not enough, a survey comes first and the fixed-price quote follows.
Who do I call if my air conditioning fails in Custom House out of hours?
Custom House is within our area, and the emergency line is open 24/7. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
Do you offer maintenance contracts?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is written up, with F-Gas records where refrigerant work is involved.
Which brands do you work with?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
How long does the work take?
On site, it takes a single visit for many faults, while some repairs need a second visit once parts arrive. Larger systems naturally take longer, and the quote will say how long.
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 electrical circuit is notifiable building work unless a registered competent person does it.
What causes ice on the indoor coil?
Ice is a symptom of low airflow or low refrigerant. A clogged filter, a fan problem or a leak are typical. Switch the system off, let it thaw and ring 07833 053749 or drop us a line.
What we do, step by step
You don’t need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and the rest is down to us. Before we leave, the area is tidied and we explain what we’ve done. In a London area like Custom House, parking and access are worth sorting out before the day.
- You describe the fault, the make and any error code, ideally with a photo.
- At the property, readings and tests narrow the problem down to its cause.
- We explain the cause and give you a fixed price for the repair before any work goes ahead.
- The repair is carried out, and any refrigerant work is leak tested and recorded.
- We run the system, check it’s working properly and note anything else that needs attention.
Getting ready for the visit
- Make sure we can reach the outdoor unit, or where it will go
- Mention any parking restrictions near the property
- Keep pets out of the rooms we’re working in
Getting a quote
The quickest way to a quote is to send photos: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and simple jobs can often be priced without a visit.

After we’ve gone
So the system stays in good health:
- Note any error code, or take a photo of the display
- Only let an F-Gas qualified engineer work on the refrigerant
- Turn the system off if it’s dripping water
A returning symptom is worth reporting quickly. Describe what’s happening and any error code, and we will look into it.
Use the system sensibly. Choose the right mode and a moderate set temperature, and keep doors and windows closed while it runs, so it isn’t running flat out all day.
When to call us in Custom House
When ice forms on the pipes or coil, something else is wrong. Low airflow from blocked filters or a failing fan, or low refrigerant from a leak, are the common causes. Switch the system off and let it thaw before calling us.
Any of these is worth a proper look:
- A unit blowing warm air
- A unit that barely blows any air
- A system that won’t switch on
Schools such as St Joachim's Catholic Primary School can report a fault on the 24/7 line and have non-urgent work done out of term.
Questions to ask before booking
- Proof of F-Gas company certification
- Whose warranty applies, and on what terms
- If the quote is based on a survey, photos or a diagnosis

From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
