About our air conditioning servicing in Old Oak Common
Whether a leak check is required depends on how much refrigerant the system holds and which refrigerant it is. GOV.UK sets the frequency by the system’s tonnes of CO2 equivalent (tCO2e): at least every 12 months from 5 to under 50 tCO2e, and every 6 months from 50 to under 500 tCO2e. We tell you which band your system falls into and carry out the checks it needs. If you’re dealing with water dripping from the indoor unit and a unit showing a fault code, we can help.
For a flat or office in Old Oak Common, tell us where the outdoor unit is and how we reach it, as that affects how long the service takes. If the building has a managing agent, we can book in with them.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

Common problems we fix in Old Oak Common
How often a system needs servicing depends partly on how hard it works. A system used for heating as well as cooling, or one in a busy workplace, sees far more running hours, and they benefit from regular attention.
It’s time to call us if you are dealing with:
- Systems that need a 6 or 12-monthly leak check
- Drips or damp patches below an indoor unit
- New noises from the indoor or outdoor unit
For a school like Old Oak Primary School, maintenance visits can be booked out of term.
Questions to ask before you book
- How VAT is shown, and which rate applies
- Whose warranty applies, and on what terms
- Whether anyone has checked the property or the system first
Servicing in Old Oak Common: local notes
The centre of Old Oak Common lies within a conservation area. There are 4 conservation areas within a mile of the centre of Old Oak Common. For most visits that makes no difference. It only comes up when an outdoor unit has to be replaced on a protected building. The Valuation Office Agency’s council tax figures show about 42% of homes in the Old Oak Common area were built in 2000 or later, and the last census (2021) found about 67% of households live in flats. If you live in a flat, mention any roof hatch, balcony or managing agent we’ll need to get to the outdoor unit. City dust and debris build up on London outdoor units, which is why servicing matters.

Looking after it afterwards
So the system stays in good health:
- Report drips, smells or noises early
- Clean the filters between services, as the manual describes
- Close windows when the air conditioning is running
If you’d rather not keep track of service dates yourself, ask about a maintenance contract. We agree the visits and the cost up front, and we get in touch when the next one is due.
Check that the condensate pipe outside can still drain. A pipe that is been knocked or covered can back up into the indoor unit.
FAQs for Old Oak Common
How often do you service systems in Old Oak Common?
Normally once a year for homes, more often for busy business systems. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.
Do you cover Old Oak Common for air conditioning servicing?
Yes. We work across London and the South East from our base in East Grinstead, and Old Oak Common is part of that. Just ring us on 07833 053749 or use the quote form with a few details.
How long will the engineer be here for the service?
It takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. The number of indoor units and how easy they are to reach make the biggest difference, and we will give you an idea when we book.
What’s included in an air conditioning service?
Both the indoor and outdoor units are checked and cleaned: the filters, coils, drain and fans, followed by the wiring, controls and refrigerant performance. You get a record of the visit.
Will you regas my air conditioning on a service?
We check refrigerant performance on every service, but adding gas is separate work. If it’s low, a leak repair comes first and the regas follows, priced before work begins.
Will you make a mess?
Protection goes down first: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
When is an F-gas leak check required?
The rules are based on tCO2e, which comes from the refrigerant charge and its GWP. 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.
Pricing air conditioning servicing in Old Oak Common
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether it’s a simple split or a larger system
- What state the existing equipment is in
- The number of rooms, units or zones
Several rooms, units or sites on one quote can make for a more efficient booking. Mention every unit or room you need covered and we’ll price it together.
What to send for a quote
When you contact us, it’s useful to have:
- A close-up of the unit’s label showing the model number
- Any error code or flashing light on the display
- The fuse board and where it is in the property
Photos are enough for some jobs; others need a visit first. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.
How the visit works
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First comes a careful look at the system or the space, then the work itself, and finally we test, record and explain. The middle part takes longest, which takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. Before a visit in Old Oak Common, we ask where the van can stop and how we reach the outdoor unit.
- First, we agree a time and confirm the cost of the service.
- The engineer runs the system and checks how it’s performing.
- Then the cleaning: filters, coils, fan and the drain line.
- Electrical and refrigerant checks follow, including a leak check if the rules require one.
- We run the system again and leave you a service record.
Before we arrive
- Keep pets out of the rooms we’re working in
- Clear the space around the indoor unit, or where it will go
- Mention any parking restrictions near the property
Get a fixed-price quote
Our prices page gives typical ranges, but your quote is based on your job, because no two buildings, rooms or systems are the same. Once we have looked at the job, from photos or on a survey, you get a fixed price. To start, give us a ring on 07833 053749 or email us.
