About our air conditioning servicing in Northumberland Heath
We’re asked to service systems for many different reasons: a musty smell, weak cooling, water dripping indoors or simply because it’s been a while. The same full set of checks applies whatever prompted the call. Typical jobs include leak check records that need bringing up to date and drips or damp patches below an indoor unit, on VRF systems, wall-mounted split systems and ducted systems.
Systems in Northumberland Heath often run in both summer and winter, which is a good reason for a yearly service. Outdoor units on balconies and roofs pick up city dust and debris, which a service clears.
AirCon Doctor is an F-Gas certified company and 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.

Owner checks or an engineer?
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Never try to top up, release or handle refrigerant yourself. 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.

If a repair turns into a replacement on a listed building or in a conservation area, we check the planning position before changing the outdoor unit.

Your questions about air conditioning servicing in Northumberland Heath
How do I get a quote for air conditioning servicing in Northumberland Heath?
Use the quote form, or email, with a description of the job. Straightforward work can be priced remotely. Bigger jobs get a survey and a written fixed price.
How often should air conditioning in Northumberland Heath be serviced?
A yearly visit is right for most households. Some manufacturers’ warranty terms ask for regular servicing, so it’s worth keeping the records.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
What does an air con service involve?
Filters, coils, fans and the condensate drain are all cleaned and checked. The electrics, controls and refrigerant circuit are tested too, with an F-gas leak check where the system requires one.
How soon will you get back to me?
You will hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
Will you regas my air conditioning on a service?
Refrigerant is only added after the leak that caused the loss has been dealt with. Topping up without finding the leak means the gas escapes again, so we don’t recommend it.
Does my air conditioning need an F-gas leak check?
It depends on the system’s tonnes of CO2 equivalent (tCO2e). At 5 to under 50 tCO2e, it’s at least every 12 months; at 50 to under 500 tCO2e, every 6 months. Hermetically sealed systems under 10 tCO2e are exempt.
What happens on the day
Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we have done and answer any questions, and anything that needs a follow-up is pointed out there and then. The visit takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in Northumberland Heath.
- We ask about the system: the make, the number of indoor units and any problems you’ve noticed.
- The engineer switches the system on and checks how it behaves before taking anything apart.
- Filters, coils and the condensate drain are cleaned and cleared.
- Temperatures and pressures tell us how the refrigerant circuit is doing, alongside checks on the wiring and controls.
- We leave you a record of the service and explain anything we found.
Getting ready for the visit

What air conditioning won’t do
Before you book, it helps to know what’s not included:
- Poor original installation, such as drains without a proper fall
- A refrigerant leak, which needs finding and repairing, not topping up
- Heat gains the system was never sized for
Not sure which it is? You can call 07833 053749 and we’ll tell you honestly before booking.
Parts of the system we cover
- Ducted systems
- Wall-mounted split systems
- Air-to-air heat pumps
- Multi-split systems
- Ceiling cassettes
- VRF systems
For landlords and property managers
Records are where property maintenance often slips. Each visit produces a dated record, plus the F-Gas records where refrigerant is involved, so you can show what was done and when.
From a single flat to a whole estate, the approach is the same: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
