Air conditioning repair in Upper Holloway, done properly
Refrigerant does not get used up, so if it’s low, there’s a leak. Topping up without a repair only delays the next breakdown. We find and fix the leak, pressure test, evacuate and recharge to the manufacturer’s charge, then record it in the F-Gas records. Common call-outs are for a unit that has lost refrigerant and a system that runs but doesn’t cool the room, on ceiling cassettes, VRF systems and multi-split systems.
London systems in Upper Holloway often run long hours in summer, which is when weak cooling, leaks and error codes tend to appear. The error code on the display, the make and the model are the most useful things to send us.
We’re an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Your questions about air conditioning repair in Upper Holloway
Do you cover Upper Holloway for emergency air conditioning repairs?
Upper Holloway 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.
Can you do air conditioning repair in Upper Holloway?
Yes, Upper Holloway is within the area we cover. Get in touch with the details and we reply the same working day.
Do you look at the job first?
Yes. Photos often do the job for simple work, while bigger systems and repairs that need testing get a visit.
Will you make a mess?
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 before we leave.
What causes ice on the indoor coil?
The coil gets too cold when air can’t move across it or when the refrigerant charge is low. A dirty filter is worth checking first and if that is not it, we’ll find the cause.
Can you look at a system you didn’t fit?
Yes. Systems fitted by other companies are fine, on all the main brands. Tell us the make and model and send any paperwork you have.
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 it works
There’s very little for you to do 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 Upper Holloway.
- 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.
- The fault is explained simply and the repair priced up front.
- 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.
Preparing for the visit
- Let us know if the units are on a roof, a high wall or in a locked area
- Make sure we can reach the consumer unit or fuse board
- Dig out any previous service or F-Gas records
Getting a price
Photos are enough for some jobs; others need a visit first. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, the quote is fixed before anything goes ahead.

Leave it or put it right?
The rules on refrigerant affect repairs. Repairing and recharging existing R410A systems is still legal, but R410A is getting scarcer and dearer to buy as the GB phase-down tightens and we weigh that up when we advise you. Booking in spring means a home or office in Upper Holloway is ready before the first hot week.
Whatever the property, the quote works the same way: the equipment, the access, the work involved and the time it takes. Call for a fixed-price quote and we’ll explain each part.
Why us?
- Listed on Checkatrade
- A 24/7 emergency line
- Enquiries answered the same working day
- Leading brands including Daikin, Mitsubishi Electric and Fujitsu

What affects the cost of air conditioning repair
Some jobs are bigger than they look, and some smaller. What affects the quote:
- What we find on the survey or diagnosis
- How many units are involved
- The pipe route between the units
What you pay reflects the actual work. That is why we look at the job first, from pictures or on a survey, and the price is agreed before we start.
Helping us quote
To speed up the quote, please include:
- Photos showing the indoor unit and the space around it
- Where the outdoor unit is, or where you’d like it
- The make and model of the system, from the label
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and simple jobs can often be priced without a visit.
What air conditioning repair can’t fix
Before booking, it helps to know what’s not included:
- No power to the building at all
- A discontinued model with no parts available
- A building problem rather than a system fault
If in doubt, give us a ring on 07833 053749 or email us and we’ll say what we think before you book.
Parts of the system we cover
- Ceiling cassettes
- Multi-split systems

What a repair looks like in Upper Holloway
The centre of Upper Holloway lies within a conservation area. Draw a one-mile circle round the middle of Upper Holloway and it takes in 7 conservation areas. Listed buildings are part of the picture here: about 14 within half a mile of the centre, such as Cromwell House (grade I). If a repair turns into a replacement on a listed building or in a conservation area, we check the planning position before changing the outdoor unit. The Valuation Office Agency’s council tax figures put about 59% of homes in Upper Holloway and the neighbourhoods around it before 1919, and the 2021 Census found about 78% of households live in flats. In flats, outdoor units are often on balconies, roofs or high walls, so tell us how we reach yours. In London, access to outdoor units on roofs and balconies can need planning, so tell us how to reach yours.
