Smithfield air conditioning servicing
Air conditioning servicing in and around Smithfield, from the first look to the final check with the price fixed before work begins.
- No service record for the last year or more
- Air conditioning that isn’t cooling as well as it did
- Drips or damp patches below an indoor unit
What the work involves, system by system
Wall-mounted, ducted and cassette units
Ceiling cassettes are common in offices, shops and restaurants. We drop the grille to clean the filters and check the condensate pump.
Refrigerant performance and leak checks
The engineer looks at how well the system is moving heat, checking temperatures and pressures against what the system should achieve. If something points to a leak, we tell you and set out the options.
Air conditioning servicing in Smithfield, done properly
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, and the servicing happens on schedule. The work covers ducted systems, ceiling cassettes and multi-split systems, and the jobs we see most are water dripping from the indoor unit and a musty or damp smell when the unit starts.
Commercial systems in a London area like Smithfield may need F-gas leak checks as well as a service, depending on how much refrigerant it holds. We record the checks and tell you when the next one is due.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Keeping systems in Smithfield running
About 32% of homes in and around Smithfield have been built since 2000, according to Valuation Office Agency council tax records, and Census 2021 figures found about 97% of households live in flats. Outdoor units serving flats can be awkward to reach, so let us know where yours is. City dust and debris build up on London outdoor units, which is why servicing matters. The middle of Smithfield is part of the Smithfield Conservation Area. Draw a one-mile circle round the middle of Smithfield and it takes in 26 conservation areas. About 472 listed entries lie within half a mile of central Smithfield, The Charterhouse (grade I) among them. That only matters for replacements, where a new outdoor unit on a protected building can need consent.
Schools such as Charterhouse Square School can book servicing for half term or the summer break, when rooms are empty. For an office near Farringdon station, servicing can be booked before or after working hours.
Smithfield is about 1 mile north of London, in Greater London. Whatever kind of property you have in Smithfield, our engineers can help with air conditioning servicing. You will hear back from us the same working day and our emergency line runs 24/7. Count every place we list in Greater London and you reach 764, with Smithfield on the list.
Not far from Smithfield, a recent job of ours was on Greenwich High Road, Greenwich (SE10), about 5 miles south-east: installing a Mitsubishi Electric wall-mounted unit in the retail area and a second unit in the stockroom and office.

Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Keep the drain outlet clear
- Book the service at least once a year
- Call about new noises or smells rather than waiting
The best time to book the next service is now, while you remember. Spring suits systems used mainly for cooling, and autumn suits those used for heating although we service all year round.
Keep the area around the outdoor unit clear. Plants, bins and stored items piled around it get in the way of the air it needs, so clear them back.
How it works
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 don’t need a separate electrician for the electrical side. The work takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. If a freeholder or agent needs to agree the work in Smithfield, we can send them the details.
- We ask about the system: the make, the number of indoor units and any problems you’ve noticed.
- The system is run and checked before anything is opened up.
- Filters, coils and the condensate drain are cleaned and cleared.
- We check the electrics, the controls and how the refrigerant circuit is performing, and carry out a leak check where the rules call for it.
- We leave you a record of the service and explain anything we found.
How to prepare
- Make sure someone can let us in at the agreed time
- Let us know if the units are on a roof, a high wall or in a locked area
- Let us know if the building has a permit or sign-in process

FAQs for Smithfield
How often do you service systems in Smithfield?
Once a year suits most home 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 cover Smithfield for air conditioning servicing?
Yes. Smithfield is one of the places we cover. Tell us a little about the job and we’ll take it from there.
Is a regas part of an air conditioning service?
A service doesn’t include adding refrigerant. The refrigerant circuit is sealed, so a system that is short of gas has a leak. We check the refrigerant performance, and if we suspect a leak we explain how it can be found and repaired.
What does F-Gas certified mean?
For refrigerant work, both the engineer and the company need the right F-gas credentials. Ask to see proof before you book anyone and we’ll gladly show you ours.
What accreditations do you have?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we’re Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Can I fit air conditioning or a heat pump 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 can quote for the whole job, from supply to commissioning.
How soon will you get back to me?
On the same working day you contact us. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
What affects the cost of air conditioning servicing
You will get a fixed price before we start. It takes into account:
- How easy the units are to reach
- The pipe route between the units
- The brand, model and parts involved
Our prices page shows typical ranges, but your price depends on the job in front of us. For a fixed-price quote, ring 07833 053749 or email us, and we’ll talk you through it.
Helping us quote
What to send for a quote:
- Any error code or flashing light on the display
- The rating plate or label on any existing unit
- Photos showing the indoor unit and the space around it
For a fixed-price quote, call us on 07833 053749 or fill in the contact form and tell us about the property and what you need. A few photos make it quicker. We reply to enquiries the same working day.
