Air conditioning servicing around Deptford
The middle of Deptford is part of the Deptford High Street Conservation Area. There are 12 conservation areas within a mile of the centre of Deptford. Church of St Paul, listed at grade I, is one of roughly 56 protected buildings and structures in the half-mile around Deptford’s centre. That only matters for replacements, where a new outdoor unit on a protected building can need consent. VOA council tax data show about 34% of homes in Deptford and the neighbourhoods around it were built in 2000 or later, and about 79% of households live in flats, according to Census 2021 figures. In flats, outdoor units are often on balconies, roofs or high walls, so tell us how we reach yours. City dust and debris build up on London outdoor units, which is why servicing matters.
Offices and shops near Deptford station can have their systems serviced without closing. For a school like Tidemill Academy, maintenance visits can be booked out of term.

About our air conditioning servicing in Deptford
An annual service is £95–£150 + VAT, confirmed before the visit is booked. Larger systems with several indoor units, ducted units or commercial plant are priced on their details. Either way, you know the cost before the engineer arrives. If you’re dealing with leak check records that need bringing up to date and drips or damp patches below an indoor unit, we can help.
Systems in Deptford 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.
We are an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Rented and managed buildings
Larger air conditioning systems in buildings need more than servicing: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Let us know who will give us access and who the records should go to, and we will keep everyone informed.
Why deal with it now?
Some manufacturers may set conditions on their warranties, and servicing may be among them. If yours does, a gap in the service history could matter if a fault comes up later. We can go through the terms with you. Planning ahead in Deptford means you choose the date, not the weather.
Leaving a fault or an overdue service rarely makes the work cheaper. Small problems, from blocked filters to slow leaks, tend to get worse, and a system working harder than it should costs more to run. If you’re not sure what’s needed, phone us on 07833 053749 or write to us at info@aircondoctor.co.uk for straight advice and a fixed price.

The process
The work area is kept tidy throughout, with sheets down and mess cleared as we go. Any holes, fixings or cable routes are agreed with you before we drill. The visit takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. Send us a few phone pictures and we can often price a straightforward job in Deptford before visiting.
- First, we agree a time and confirm the cost of the service.
- Before any cleaning, the system is run so we can see how it behaves.
- We clean the filters, coils and fans and clear the condensate drain.
- We check the wiring, controls and refrigerant circuit, and leak check systems that need it.
- We run the system again and leave you a service record.
Getting ready for the visit
- Make sure someone can let us in at the agreed time
- Find the manual or the paperwork for the system, if you have it
- Clear a path to the units and the space around them

FAQs for Deptford
Do you cover Deptford for air conditioning servicing?
Yes. We work across London and the South East from our base in East Grinstead, and Deptford is part of that. Tell us a little about the job and we’ll take it from there.
How often do you service systems in Deptford?
Usually once a year for homes, more often for busy business systems. Larger systems holding 5 tonnes CO2 equivalent or more also need a leak check at least every 12 months under the F-gas rules.
Do you work on all makes?
We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
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 when we finish.
Can I fit air conditioning or a heat pump myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
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 instance, is about 2.0 tCO2e. We read the charge from the label and work it out for you.
What do you check on an air conditioning service?
A full clean and check of the system. That means filters, coils and drains, plus electrical connections, controls and refrigerant performance with leak checks where the rules require them.
What owners can safely do
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Owner care supports servicing; it doesn’t replace it. 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.
