System by system
Filters
A clogged filter cuts the airflow through the unit. That makes it harder for the system to reach the temperature you’ve set, which is why filters are always part of the service.
Wall-mounted, ducted and cassette units
With a ducted system, the unit is hidden above the ceiling. We need access to the unit, its filters and its drain, so let us know where the hatch is.
Air conditioning servicing for homes and businesses in Cores End
Servicing is also a chance to spot faults early. We listen to the fans, look at the pipework and insulation, test the controls and check the electrical connections are sound, and tells you about anything that looks like it’s heading for trouble. The work covers ceiling cassettes, air-to-air heat pumps and wall-mounted split systems, and the jobs we see most are iced-up coils or pipework and F-gas leak checks falling due.
We plan the trip to Cores End and can service more than one unit in one visit, which keeps it simple.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

What we do, step by step
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. You only need to give us clear access to the units, or their planned positions, and to the fuse board. On site, the work takes an hour or so for a single wall-mounted unit, longer for a multi-split system. Photos of the existing unit help with repairs and servicing in Cores End.
- 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 is cleaned and checked, and debris cleared from around it.
- 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.
Preparing for the visit
- Mention any parking restrictions near the property
- Tell us about any building rules, permits or sign-in
- Clear access to the fuse board

Honest limits
We will not sell you work that does not address the problem, so these are the things it won’t cover:
- Pipework or drainage that was badly installed in the first place
- Heat from large windows, roof spaces or equipment beyond the system’s capacity
- A system that’s too small for the room it serves

Questions from Cores End
Do you cover Cores End for air conditioning servicing?
We do: Cores End falls inside our working area. Get in touch with the details and we reply the same working day.
How often should air conditioning in Cores End be serviced?
For most homes, once a year. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.
Are you F-Gas certified?
AirCon Doctor is an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We’re also Checkatrade members.
Do you work on systems someone else installed?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Who is responsible for leak checks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
What does F-Gas certified mean?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. In Great Britain, that certification is a legal requirement, not an optional extra, and we hold it.
What’s included in an air conditioning service?
A full clean and check of the system. Filters, coils and drains are cleaned, and the electrics, controls and refrigerant circuit checked with leak checks where the rules require them.
