How the visit works
The visit goes in the diary at a time that works for you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the photos you sent. Anything unexpected is raised with you before we go further. After that, it takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. Let us know who controls access to the building in Hounslow, as that saves time on the day.
- It begins with a few questions about the make, the rooms served and any symptoms.
- Inside, the filters, coil and drain tray of each indoor unit are 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.
- Anything we find is explained, with a fixed price if it needs a repair.
Preparing for the visit
- Clear access to the fuse board
- Let us know where we can park and unload
- Mention any roof access, ladders or high-level work

Air conditioning servicing in Hounslow
Air conditioning pulls room air through a filter and across a cold coil many times an hour. Dust, fluff and anything else in the air ends up on those parts. Servicing removes it, letting air pass through the unit properly and the condensate drain away. The work covers ceiling cassettes, ducted systems and multi-split systems, and the jobs we see most are drips or damp patches below an indoor unit and humming, rattling or squealing from the system.
For a flat or office in Hounslow, tell us where the outdoor unit is and how we reach it, as that affects how long the service takes. Managed buildings may need the visit booked through the agent.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Let and managed properties
Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We’re happy to deal with either side and send the records to whoever needs them.
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Let us know who will give us access and who the records should go to, and we will keep everyone informed.
Aftercare tips
Systems last better with the right care. Here’s what we suggest:
- Read the warranty conditions for your brand
- Book the service at least once a year
- Leave space around the outdoor unit for air to flow
Put the next service in the diary right away. Many people book in spring, before the cooling season, or in autumn if they use the system for heating, though any time of year works.
Give the outdoor unit room to breathe. Leaves, garden waste, bins and climbing plants all restrict the airflow and should be moved away.
Questions from Hounslow
How often do you service systems in Hounslow?
Once a year suits most home systems. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.
Can you do air conditioning servicing in Hounslow?
Yes. Hounslow is one of the places we cover. Just give us a ring on 07833 053749 or use the quote form with a few details.
Will you regas my air conditioning on a service?
A regas is a separate job, done once a leak has been found and fixed. Adding gas without a repair just lets it leak away again and that’s money wasted.
Do you do service contracts for air con?
Yes. A contract sets out how often we visit and what each visit covers with the price fixed when you accept the quote. It suits anyone who would rather not track service dates.
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’s a legal requirement, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
Who has to arrange F-Gas leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Can you look at a system you didn’t fit?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Send us the make and model, and any records you have.
Keeping systems in Hounslow running
The Valuation Office Agency’s council tax figures show about 30% of homes in Hounslow and the neighbourhoods around it were built in 2000 or later, and Census 2021 figures found about 49% of households live in flats. Balcony, roof or high wall? Knowing where a flat’s outdoor unit is helps us bring the right access kit. London outdoor units collect city dust and grime, so the outdoor coil gets particular attention on a service. 3 conservation areas lie within a mile of central Hounslow. Worton Hall, listed at grade II, is one of roughly 6 protected buildings and structures in the half-mile around Hounslow’s centre. We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that.
If you run premises near Hounslow station, ask about servicing several units in one visit. If you look after a school such as Chatsworth Primary School, servicing is easiest in the holidays.
