How we handle air conditioning servicing in Dulwich
Maintenance contracts suit anyone who would rather not have to remember when the next service is due. We agree the visits, what each one covers and the price with your quote, so the system is looked after on a regular schedule. We’re often asked to deal with smells coming from the indoor unit and no service record for the last year or more, on ducted systems, wall-mounted split systems and multi-split systems.
Systems in Dulwich often run in both summer and winter, so a yearly service keeps them efficient. Outdoor units on balconies and roofs pick up city dust and debris, which a service clears.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. Keep it with the system’s paperwork so it’s to hand next time.

Before you call an engineer
Good habits make our visits easier, not unnecessary. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.

Questions from Dulwich
What’s the best way to get a price for air conditioning servicing in Dulwich?
Send us photos 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.
How often should air conditioning in Dulwich be serviced?
Typically once a year for homes, more often for busy business systems. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.
Do you look at the job first?
Yes, always. We diagnose before we treat: the survey tells us what the job needs and how to do it, and the quote is based on that.
Is Dulwich in your area?
Yes. Dulwich is part of the area we cover, within the South East and London area we cover. Our base is in East Grinstead, West Sussex.
Which accreditations do you hold?
AirCon Doctor is an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We are members of Checkatrade too.
How long does the visit take?
It depends on the job, but in most cases it takes a short visit for one split system, longer for multi-split, ducted or commercial plant. We will confirm it with the quote.
When will I hear back?
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.
Leave it or put it right?
If your system needs F-gas leak checks, they are not optional. Missing one leaves you without the check and the record and it’s far easier to stay on schedule. Getting the work done in Dulwich before summer avoids the busiest weeks.
Putting several jobs into one visit can make for a more efficient booking. Mention every unit or room you need covered and we will price it together.

How the visit works
The first job on site is protection: dust sheets over floors and furniture near the work and nothing is moved without asking you. Then the electrics are made safe and the work begins. It takes an hour or two for most homes, and longer where there are several indoor units or a ducted system, and we clear up before we go. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in Dulwich.
- You tell us the brand, the number of indoor units and any symptoms.
- Each indoor unit has its covers lifted so the filters, coil and tray can be cleaned.
- The outdoor unit gets its own clean, with leaves and debris cleared away.
- Readings are taken on the electrics and refrigerant circuit, and the controls are tried in each mode.
- If a repair is needed, you hear why and what it costs before anything is done.
How to prepare
- Make sure we can reach the consumer unit or fuse board
- Move furniture away from the wall where we’ll be working
- Keep pets out of the rooms we’re working in
