Blackheath: your questions answered
Who do I call if my air conditioning fails in Blackheath out of hours?
The emergency line is open around the clock, and Blackheath is one of the places it covers. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
How do I get a quote for air conditioning repair in Blackheath?
Use the quote form, or email, with a description of the job. Straightforward work can be priced remotely. Bigger jobs get a survey and a written fixed price.
Can I do any of the installation myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Can you set up regular servicing?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Every visit is recorded, with F-Gas records where refrigerant work is involved.
My air con is showing an error code. What should I do?
The code is the system’s own clue to the fault, but it isn’t the whole answer. Write down the code and turn the unit off if it has stopped, then phone us on 07833 053749, or email if that’s easier.
Do you protect the property while you work?
We start with protection: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
Why is there ice on my air conditioning pipes?
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 call 07833 053749 or use the quote form.
Air conditioning repair in Blackheath, done properly
Refrigerant doesn’t get used up, so if it’s low, there’s a leak. Simply adding gas means it will leak away again. We locate the leak, repair it, test, evacuate and recharge and write it up in the F-Gas records. The work covers VRF systems, wall-mounted split systems and ducted systems, and common reasons people get in touch are ice forming on the indoor unit or pipes and a unit that won’t start.
Air conditioning repairs in Blackheath are often in flats, offices and shops, where the outdoor unit may be on a balcony, a rear wall or the roof. Telling us where the outdoor unit is and how we reach it saves time on the visit.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

Air conditioning repair around Blackheath
The Valuation Office Agency’s council tax figures put about 42% of homes in the Blackheath area before 1919, and Census 2021 figures found about 66% of households live in flats. If you live in a flat, mention any roof hatch, balcony or managing agent we’ll need to get to the outdoor unit. In London, access to outdoor units on roofs and balconies can need planning, so tell us how to reach yours. Central Blackheath is inside the Blackheath Conservation Area. Draw a one-mile circle round the middle of Blackheath and it takes in 3 conservation areas. Historic England lists about 112 buildings and structures within half a mile of the centre of Blackheath, including Numbers 1 to 14 (consecutive) the Paragon (grade I). Day-to-day work on an existing system is not affected; a replacement outdoor unit on a protected building might be.
When cooling fails at a school like All Saints' Church of England Primary School Blackheath, we can time non-urgent repair work around lessons. Near Blackheath station, as anywhere, a photo of the error code on the controller is the quickest way to start a repair.

What you can do yourself, and what needs us
Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It makes our diagnosis quicker, and a photo of the display helps even more.
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrical side needs a competent person. If you need something moved, we can quote for it.
The process
You do not need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. Before we leave, the area is tidied and we explain what we have done. A note on parking and access helps us plan a visit to Blackheath.
- You tell us the symptoms, the make and any error code.
- On the diagnosis visit, we test the electrics, airflow, drain and refrigerant.
- The fault is explained simply and the repair priced up front.
- With your go-ahead, we carry out the repair, recording any refrigerant work.
- The system is run and checked, and you get a written note of the repair.
How to prepare
- Mention any parking restrictions near the property
- Mention any roof access, ladders or high-level work
- Plan for pets to be kept clear during the visit
Getting a price

Advice
Keeping the system healthy
Aftercare is straightforward, and it makes the next visit easier:
- Book an annual service after the repair
- Stop the unit if water is coming through a ceiling
- Check the filter, the mode and the set temperature before calling us
After a repair, the basics matter: clean filters every few weeks in heavy use and space around the outdoor unit. An annual service is the best way to catch the next fault before it stops the system.
Sensible use helps. Moderate settings and a closed room mean less strain, so it isn’t running flat out all day.

We work for landlords, letting agents and managing agents as well as homeowners and businesses. Tell us who the contact on site is and who should receive the paperwork, and we’ll keep everyone informed.
Bigger systems bring extra duties: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We can arrange it, prepare the system for it and fix what it finds.
From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
