About our air conditioning repair in Mayfair
Our emergency line runs 24/7 for urgent breakdowns, 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 will talk you through what happens next. If the problem is a system that keeps cutting out and a unit that has lost refrigerant, we can sort it out.
London systems in Mayfair often run long hours in summer, and that’s when faults show: weak cooling, water leaks, error codes or a unit that won’t start. A photo of the error code and the unit’s label helps us arrive with the right parts in mind.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual so it’s to hand next time.

Common questions in Mayfair
Is there an emergency air con repair line for Mayfair?
Yes. Our 24/7 emergency line covers Mayfair. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
Can I get a fixed-price quote for air conditioning repair in Mayfair?
Send us pictures of the room or the system and a few details about the property. Simple jobs can be priced from photos; otherwise we arrange a site survey and then give you a fixed-price quote.
How soon will you get back to me?
You’ll hear from us the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
How long will you be on site?
On site, it takes anything from an hour or so to a full day, depending on the fault and the parts. Bigger or more complicated systems take longer, and we’ll tell you what to expect.
Do you provide F-Gas records?
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.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule with a fixed price. Leak checks required by the F-gas rules can be built in for larger systems.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
Aftercare tips
Once we’ve finished, these simple steps help:
- Do not keep resetting a breaker that trips
- Only let an F-Gas qualified engineer work on the refrigerant
- Keep to the service interval the manufacturer recommends
If a repair does not make sense, you’ll hear it from us, with the reasons. If replacement is the better option, we can quote for it on the same visit.
Book an annual service. A service cleans the coils and drain, checks the electrics and the refrigerant circuit and catches small faults early and that’s usually simpler than a breakdown repair.
System by system
VRF systems
VRF systems often hold enough refrigerant to need regular F-gas leak checks. Any leak we find and repair is recorded, and the operator keeps the records.
Condensate drains and pumps
The drain is cleared, the pump tested and the fall checked until the condensate runs away properly. If a pump has failed, we replace it and test it before we leave.
Pricing air conditioning repair in Mayfair
Your quote is based on your property. We consider:
- The electrical supply and whether a new circuit is needed
- The brand, model and parts involved
- A single visit or a regular plan
Leaving a fault or an overdue service rarely makes the work cheaper. Small problems, from blocked filters to slow leaks, tend to get worse, and a struggling system uses more electricity to do less. If you’re not sure what’s needed, ring us on 07833 053749 or email us and we’ll give you an honest view and a fixed price.
What we need to know
Simple jobs can often be priced from photos and some basics. Send what you can of the following:
- Your consumer unit or fuse board
- The paperwork from the last service, if you have it
- A short video of any fault, such as a noise or a flashing light
To get a fixed-price quote, ring 07833 053749 or use the quote form and tell us about the property and what you need. A few photos make it quicker. You’ll hear back from us the same working day.

What happens on the day
Each visit follows the same order: check the plan with you, put the dust sheets down, do the work, check the system and talk you through it. On site, the work takes a single visit for many faults, while some repairs need a second visit once parts arrive. Before a visit in Mayfair, we ask where the van can stop and how we reach the outdoor unit.
- Tell us the make, the symptoms and any error code, and send a photo of the display if you can.
- The engineer reads the fault codes and checks the electrics, airflow, drain and refrigerant circuit.
- 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.
- The system is run and checked in every mode, and we tell you about anything else we noticed.
Before we arrive
- Keep pets and children away from the work area
- Make sure we can reach the consumer unit or fuse board
- Make sure someone can let us in at the agreed time
