Air conditioning servicing in Charlton, done properly
Many manufacturers attach conditions to their warranties, and some of those may include regular servicing. Each brand sets its own terms, and we can explain what yours says. You get a record of each service to keep with the warranty paperwork. The work covers air-to-air heat pumps, ceiling cassettes and multi-split systems, and people most often call us about error codes or flashing lights on the indoor unit and air conditioning that isn’t cooling as well as it did.
Several units at a home near Charlton can be serviced in one visit, which keeps it simple.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

Keeping systems in Charlton running
The centre of Charlton lies within the Charlton Conservation Area. There are 5 conservation areas within a mile of the centre of Charlton. Historic England lists about 9 buildings and structures within half a mile of the centre of Charlton, including Maydencroft Manor (grade II*). That only matters for replacements, where a new outdoor unit on a protected building can need consent. At about 31 miles from central London, Charlton sits inside the area we cover across London and the South East.
Site managers at schools like Highbury Infant School and Nursery can have the site’s units serviced during a holiday. Booking before the first hot spell means the system is ready when you need it.

How it works
The visit goes in the diary at a time that works for you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the photos you sent. If something is different, we talk it through with you before carrying on. After that, it takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. Photos of the existing unit help with repairs and servicing in Charlton.
- It begins with a few questions about the make, the rooms served and any symptoms.
- Each indoor unit has its covers lifted so the filters, coil and tray can be 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.
- If a repair is needed, you hear why and what it costs before anything is done.
How to prepare
- Clear access to the fuse board
- Find the manual or the paperwork for the system, if you have it
- Make sure someone can let us in at the agreed time

Advice
What else we do in Charlton
What you can do yourself, and what needs us
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
FAQs for Charlton
Can you do air conditioning servicing in Charlton?
Yes. Charlton is one of the places we cover. To start, ring 07833 053749 or write to us at info@aircondoctor.co.uk with a few photos.
Do you cover smaller places like Charlton?
Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Whose job is it to check the system for leaks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We will work out which band applies to yours.
Do you work on commercial properties?
Yes. From a single let flat to offices, shops and public buildings, we work the same way: a look first, a fixed-price quote and written records.
Are you F-Gas certified?
We are an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re also Checkatrade members.
How often should air conditioning be serviced?
We recommend an annual service and more often for systems in constant use. The manufacturer’s warranty terms may say something about servicing, so it’s worth reading them.
How quickly will you reply?
The same working day. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
For landlords and property managers
Portfolio owners often want one contractor and one number. Our area covers Greater London and the South East, so a run of properties can go into one programme and kept on a regular cycle.
We also work for facilities teams in offices, schools and public buildings across Hertfordshire. Work can be phased by floor, zone or building to keep disruption down.
From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
