About our air conditioning repair in Hadley
Not sure whether it’s worth calling an engineer? Check the filter, the mode, the set temperature and the remote’s batteries first, and if that doesn’t fix it, call us on 07833 053749 or send an email. We reply to enquiries the same working day. The work covers ducted systems, ceiling cassettes and multi-split systems, and the jobs we see most are a system that keeps cutting out and a noisy indoor or outdoor unit.
London systems in Hadley 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.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

How the visit works
If the system has to be off for part of the visit, we tell you before any work starts, so you can plan around it. For businesses, we can typically work room by room or zone by zone. The work takes as long as the fault needs, from a quick fix to a return visit for parts. If your building in Hadley has a managing agent, a concierge or sign-in rules, mention them when you book.
- We start with what the unit is doing, the make and any code.
- On the diagnosis visit, we test the electrics, airflow, drain and refrigerant.
- The fault is explained simply and the repair priced up front.
- Once agreed, the repair goes ahead.
- It’s tested running, and the write-up is left with you.
How to prepare
- Tell us about any building rules, permits or sign-in
- Arrange for someone to be there to let us in
- Make sure we can reach the outdoor unit, or where it will go
Getting a quote

Common questions in Hadley
How do I get a quote for air conditioning repair in Hadley?
The easiest way is to give us a ring on 07833 053749 or fill in the contact form with a few details and pictures. Straightforward work can be priced remotely. Bigger jobs get a survey and a written fixed price.
Do you cover Hadley for emergency air conditioning repairs?
Yes: ring the emergency line, day or night, from anywhere in Hadley. Have the make, model and error code ready, and we’ll talk you through what happens next.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
Why isn’t my air con cooling?
Common causes are a blocked filter, the wrong mode or set temperature, an outdoor unit that cannot breathe, a failed sensor or board, or low refrigerant from a leak. Check the filter and the settings first, then phone 07833 053749 or fill in the contact form if it’s still not cooling.
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
What does the error code on my air conditioning mean?
Codes differ by brand, and the same code can cover several faults. Send us a photo of the display with the make and model, and we will diagnose the fault on site.
Do I get paperwork after the visit?
Yes, always. New installations come with commissioning details, F-Gas records and warranty information, while repairs and services get a written note of what was found and done.
How we price air conditioning repair
The survey or diagnosis tells us what the work involves. The main factors are:
- A single visit or a regular plan
- Access, including height, roofs and ladders
- Whether the existing supply is suitable
What you pay depends on the system and the number of rooms or units, how easy the units are to reach and the parts and time the job needs. You get a fixed price before we start, so you know where you stand.
Asking for a quote
Photos let us diagnose from a distance. Try to include:
- The postcode and whether it’s a home, flat or business
- Where the outdoor unit is, or where you’d like it
- Photos showing the indoor unit and the space around it
VAT is set out clearly on every quote, and the rate that applies to your job is stated. VAT can differ between homes and businesses and between kinds of work, so we confirm it on the quote. For a fixed-price quote, ring us on 07833 053749.
Safe owner checks
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
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 or a short video of the display is even better.
Leave it or put it right?
A struggling system costs more to run. A dirty coil, a blocked filter or a low refrigerant charge all make the system work harder for less cooling and the extra work wears the parts faster. Getting the work done in Hadley before summer avoids the busiest weeks.
Whatever the property, the quote works the same way: what’s needed, how we reach it, the parts and the labour. Call for a fixed-price quote and we’ll go through it with you.

Air conditioning repairs in Hadley: local notes
Hadley’s centre is no more than about a third of a mile from the Monken Hadley Conservation Area. In the mile around Hadley’s centre, 2 conservation areas have been designated. Listed buildings are part of the picture here: about 77 within half a mile of the centre, such as Church of St John the Baptist (grade II*). Should a unit ever need replacing on a listed building or in a conservation area, ask us about consent first. About 42% of homes in Hadley and the neighbourhoods around it were built before 1919, according to the Valuation Office Agency’s council tax figures. Access to the outdoor unit is the one detail that most changes how a visit is planned. In London, access to outdoor units on roofs and balconies can need planning, so tell us how to reach yours.
The rating label on the unit gives the model number, which helps us bring the right parts. If a system fails at a school such as Susi Earnshaw Theatre School, our 24/7 line takes the call, and planned repairs can wait for the holidays.
