About our air conditioning repair in New Barnet
A sealed system shouldn’t lose refrigerant, 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 and write it up in the F-Gas records. If the problem is rattling, buzzing or grinding noises and a system that runs but doesn’t cool the room, we can help.
In a London area like New Barnet, a lot of the systems we repair serve flats and small offices, where the outdoor unit may be on a balcony, a rear wall or the roof. Knowing where the outdoor unit sits, and how to get to it, helps us plan the repair.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Each brand sets its own conditions, and we are happy to talk you through them.

Do you need air conditioning repair in New Barnet?
Most indoor unit leaks come back to the condensate. The drain may be blocked or kinked, the condensate pump may have failed, or the unit may not be level, and ice on the coil that melts can drip too.
Look out for any of the following:
- Water leaking from the unit or through the ceiling
- Frost on the pipework
- A system that keeps cutting out
If a system fails at a school such as St Mary's CofE Primary School, our 24/7 line takes the call, and planned repairs can wait for the holidays.
Questions to ask before you book

What you can do yourself, and what needs us
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and give us a ring on 07833 053749.
Don’t move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. Ask us to quote for a move instead.
Why it’s worth doing now in New Barnet
Waiting for hot weather to see whether a fault sorts itself out rarely works. If the system is faulty now, it will be faulty in a heatwave, when you need it most and it’s easier to deal with before you depend on it. If a lease or managing agent is involved in New Barnet, start the conversation early.
The price reflects the work, not guesswork. That is why we look at the job first, from pictures or on a survey, and why the quote is fixed before we start.

Your questions about air conditioning repair in New Barnet
Do you cover New Barnet for emergency air conditioning repairs?
The emergency line is open around the clock, and New Barnet is one of the places it covers. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
How do I get a quote for air conditioning repair in New Barnet?
Send us pictures of the room or the system and a few details about the property. Where pictures are not enough, a survey comes first and the fixed-price quote follows.
Will you work on another installer’s system?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Do you work for landlords and businesses?
Yes. From a single let flat to offices, shops and public buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
Why is my air conditioning blowing warm air?
It can be anything from a dirty filter to a refrigerant leak. We read any fault code and test the system to find which, then give you a fixed price to fix it.
Do you survey before quoting?
Yes. Photos often do the job for simple work, while bigger systems and repairs that need testing get a visit.
How long does the visit take?
It depends on the job, but most of the time it takes a single visit for many faults, while some repairs need a second visit once parts arrive. We will confirm it with the quote.
