About our air conditioning servicing in Chiswell Green
A service is not the same as a regas. The refrigerant circuit is sealed, so a system that’s short of gas has a leak somewhere. If the performance checks point to a leak, we explain the options for finding and fixing it rather than just topping up. Typical jobs include ice forming on the pipework or outdoor unit and an unpleasant odour when the system runs, across air-to-air heat pumps, ceiling cassettes and wall-mounted split systems.
For most homes near Chiswell Green, a service once a year keeps the system efficient and the filters clean, and regular servicing can be a condition of some manufacturers’ warranties.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

Questions from Chiswell Green
How often do you service systems in Chiswell Green?
For most homes, once a year. Some manufacturers’ warranty terms ask for regular servicing, so it’s worth keeping the records.
Do you cover smaller places like Chiswell Green?
Yes. Chiswell Green is within the area we cover across London and the South East. Send a few details and photos, and we reply the same working day.
What’s included in an air conditioning service?
A clean of the parts that collect dirt and a check of the parts that do the work. Filters, coils and drains are cleaned, and the electrics, controls and refrigerant circuit checked, and F-gas leak checks where they apply.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is the law, not just our preference, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
Which manufacturers do you install and repair?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
How quickly will you reply?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
How much time does an air con service need?
As a guide, it takes a short visit for one split system, longer for multi-split, ducted or commercial plant. Ducted units in ceiling voids and outdoor units in awkward places can add time and we will let you know before the visit.
What affects the cost of air conditioning servicing
The diagnosis comes before the price. The main factors are:
- One-off work versus a regular service cycle
- What state the existing equipment is in
- The type of system, from a single split to a larger system
Putting several jobs into one visit often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed price.
Asking for a quote
Photos let us diagnose from a distance. The most useful are:
- Your consumer unit or fuse board
- The paperwork from the last service, if you have it
- Where the property is and what kind of building it is
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and many jobs can be priced from that.
Do you need air conditioning servicing in Chiswell Green?
A slow leak can go unnoticed for a long time. Performance drops slowly and only becomes obvious when the weather is at its extreme.
Reasons to give us a call include:
- Water dripping from the indoor unit
- Ice forming on the pipework or outdoor unit
- No service record for the last year or more
For a school like Killigrew Primary and Nursery School, maintenance visits can be booked out of term.
What to look for in a quote
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
- Whether they hold F-Gas company certification, not just individual qualifications
- The make and model of any parts or equipment being quoted
What happens on the day
Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. So on the day, you do not need a separate electrician for the electrical side. On site, it takes a short visit for one split system, longer for multi-split, ducted or commercial plant. Around Chiswell Green, access is usually simple, though gates and garden access are worth mentioning.
- It begins with a few questions about the make, the rooms served and any symptoms.
- The indoor units are opened up and the filters, coils and drain trays cleaned.
- Outside, the coil is cleaned, the fan checked and the area cleared.
- 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.
Getting ready for the visit
- Mention any parking restrictions near the property
- Clear access to the fuse board
- Keep pets and children away from the work area
