Air conditioning servicing in Sutton Common
Whether a leak check is required depends on how much refrigerant the system holds and which refrigerant it is. GOV.UK sets the frequency by the system’s tonnes of CO2 equivalent (tCO2e): at least every 12 months from 5 to under 50 tCO2e, and every 6 months from 50 to under 500 tCO2e. We work out where your system sits and check it accordingly. Common call-outs are for a system that struggles to cool on warm days and a service that’s overdue, across wall-mounted split systems, multi-split systems and ducted systems.
Systems in Sutton Common often run in both summer and winter, so a yearly service keeps them efficient. In London, outdoor coils collect dust, grime and leaves, which a service clears.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, ready for the next service or a warranty query.

Pricing air conditioning servicing in Sutton Common
Before we fix a price, we need to know a few things. We look at:
- How many units are involved
- The distance and route between the indoor and outdoor units
- What kind of system it is
Every job is different, so each one gets its own fixed-price quote. The system, the access, the pipe routes and the parts involved all make a difference.
Helping us quote
To speed up the quote, send us:
- Any error code or flashing light on the display
- The outside wall, roof or yard where the outdoor unit sits or would go
- The address and the type of property
VAT is set out clearly on every quote, with the rate that applies to your job. VAT can differ between homes and businesses and between kinds of work, so we confirm it on the quote. For a fixed-price quote, call 07833 053749 or drop us a line.
What we do, step by step
Where something has to be switched off during the work, we agree it with you first, so you can plan around it. For businesses, we can normally work room by room or zone by zone. On site, it takes an hour or so for a single wall-mounted unit, longer for a multi-split system. If your building in Sutton Common has a managing agent, a concierge or sign-in rules, mention them when you book.
- You tell us the brand, the number of indoor units and any symptoms.
- Inside, the filters, coil and drain tray of each indoor unit are cleaned.
- Outside, the coil is cleaned, the fan checked and the area cleared.
- We test the electrics, the controls and how the refrigerant circuit is performing.
- We explain what we found and price any repair before it’s done.

Sutton Common: your questions answered
What’s the best way to get a price for air conditioning servicing in Sutton Common?
Send us pictures of the room or the system and a few details about the property. Straightforward work can be priced remotely. Bigger jobs get a survey and a written fixed price.
Do you cover Sutton Common for air conditioning servicing?
Yes, Sutton Common is within the area we cover. Just call us on 07833 053749 or use the quote form with a few details.
When is an F-gas leak check required?
The requirement starts at 5 tCO2e. Many small split systems fall below it: 3 kg of R32, for example, is about 2.0 tCO2e. We read the charge from the label and work it out for you.
Will you work on another installer’s system?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
How often does air con need a service?
At least once a year is a sensible routine for most systems. Where the system runs most of the year, more frequent servicing can help and it’s worth checking what your manufacturer recommends.
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 are happy to show ours.
Can I do any of the installation myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is a legal requirement, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
Different systems, different jobs
Filters
Certain indoor units carry additional filters alongside the main ones. We check these as well and explain what the manufacturer recommends.
Fans and electrics
We test the controls, the modes and the timers so you know it does what you ask.
Looking after your system
A little care keeps the system in better shape. Our advice:
- Don’t wait for a small drip to become a leak
- Read the warranty conditions for your brand
- Keep the service records with the warranty paperwork
Where the system needs F-gas leak checks, the result is recorded, and the next check is due within the period the rules set. We can book it in ahead of time.
Give the outdoor unit room to breathe. Leaves, garden waste, bins and climbing plants all restrict the airflow, so clear them back.
From one of our customers
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
