About our air conditioning repair in Dalston
For breakdowns that can’t wait, there’s a 24/7 emergency line, such as a server room overheating or water coming through a ceiling. Call 07833 053749 and tell us the make, the symptoms and any error code and we’ll talk you through what happens next. Common call-outs are for a unit that barely blows any air and a unit that has lost refrigerant, across VRF systems, ceiling cassettes and heat pumps.
Many buildings in Dalston have a managing agent or security desk, so let us know who needs to know we are coming. Outdoor units on roofs may need a key, a permit or an escort, and we plan for that before we arrive.
The records are your system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

Leave it or put it right?
For a faulty system in Dalston, an early diagnosis is the sensible first step. The visit takes anything from an hour or so to a full day, depending on the fault and the parts, and you get a fixed price for the repair before any work goes ahead, and our emergency line runs 24/7. Hot weather is when everyone in London wants air conditioning, so it’s easier to plan the work in Dalston early.
Putting the work off seldom saves money. Faults and wear in a system tend to grow, and a system working harder than it should costs more to run. If you are unsure, ring 07833 053749 or drop us a line and we will give you an honest view and a fixed price.

What we are called out for in Dalston
Some faults stop the unit completely: a failed fan motor, a fault on a circuit board, a damaged cable between the units or a tripped circuit. A breaker that trips a second time should be left off until an engineer has looked at it.
Customers usually contact us after spotting something like this:
- Water leaking from the unit or through the ceiling
- Frost on the pipework
- A system that runs but doesn’t cool the room
If your system near Dalston Junction station stops in a hot spell, our 24/7 line is open.

- Whether the manufacturer’s warranty depends on regular servicing
The process
Each visit follows the same order: agree the plan on site, protect the area, do the work, check the system and explain it all to you. The visit itself takes a single visit for many faults, while some repairs need a second visit once parts arrive. Parking bays, permits and roof or balcony access are the first things we ask about in Dalston.
- Describe the problem and the brand, and mention any code on the display.
- On the diagnosis visit, we test the electrics, airflow, drain and refrigerant.
- You get the cause explained and a fixed price for the repair.
- Once you are happy, the repair is done and any refrigerant work recorded.
- The system is run and checked, and you get a written note of the repair.
Before we arrive
- Find the manual or the paperwork for the system, if you have it
- Let us know where we can park and unload
- Keep pets out of the rooms we are working in

Some jobs can be priced from pictures, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.

FAQs for Dalston
What’s the best way to get a price for air conditioning repair in Dalston?
Use the quote form, or email, with a description of the job. Simple jobs can be priced from photos; otherwise we arrange a site survey and then give you a fixed-price quote.
Is Dalston in your area for air conditioning repair?
Yes. Dalston is one of the places we cover. To start, call 07833 053749 or drop us a line with a few pictures.
Can you repair an R22 air conditioning system?
Replacement is normally the better answer. R22 can’t be topped up with new gas, and parts for old models are scarce, so a new system on a modern refrigerant is normally the better investment.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Dalston and across Greater London. Tell us who should receive the paperwork.
Do I need to service the system to keep the warranty?
It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so check the terms or ask us. Either way, keep a record of every service.
Will I get records for the system?
Yes. It’s the record a manufacturer or the next engineer will ask to see: the date, the work, and any refrigerant added or recovered.
Why use an F-Gas certified company?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before you book and we’ll gladly show you ours.
