About our air conditioning servicing in Mongewell
Every hour, an indoor unit draws the room’s air through its filter and over its coil again and again. Whatever is in the air, from dust to pet hair, collects on the filter and coil. Servicing removes it, letting air pass through the unit properly and the condensate drain away. Common call-outs are for systems that haven’t been serviced for a while and frost or ice on the refrigerant pipes, on ducted systems, VRF systems and ceiling cassettes.
Most systems around Mongewell need servicing once a year, best done before summer.
Aftercare is simple, and most of it is in the manual: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

What happens on the day
Where something has to be switched off during the work, we agree it with you first so it does not catch you out. In a business, work can often be done one area at a time. The work takes a short visit for one split system, longer for multi-split, ducted or commercial plant. A note on how to find the property and where to park makes a visit to Mongewell easier.
- It begins with a few questions about the make, the rooms served and any symptoms.
- Each indoor unit has its covers lifted so the filters, coil and tray can be cleaned.
- Outside, the coil is cleaned, the fan checked and the area cleared.
- We test the electrics, the controls and how the refrigerant circuit is performing.
- We explain what we found and price any repair before it’s done.
Preparing for the visit
- Keep pets out of the rooms we’re working in
- Tell us about parking and loading
- Clear a path to the units and the space around them

Other services in Mongewell
Rented and managed buildings
Larger air conditioning systems in buildings need more than servicing: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We can arrange it, prepare the system for it and fix what it finds.
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Let us know who will give us access and who the records should go to and we’ll copy in whoever needs it.
Keeping systems in Mongewell running
About 44 miles out from central London, Mongewell is part of the South East area we work across. In the mile around Mongewell’s centre, 2 conservation areas have been designated. Historic England lists about 18 buildings and structures within half a mile of the centre of Mongewell, including Church of St Mary (grade II*). For most visits that makes no difference. It only comes up when an outdoor unit has to be replaced on a protected building.
Spring is a good time for a service, before the system is needed for cooling. For a school like Crowmarsh Gifford Church of England School, maintenance visits can be booked out of term.

Mongewell questions
How often do you service systems in Mongewell?
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.
Will you come out to Mongewell?
Yes, and the size of the place makes no difference to how we work. A few photos and the postcode are enough to get things started.
Will I get records for the system?
Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.
Can you look at a system you didn’t fit?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Is a regas part of an air conditioning service?
A regas is a separate job, done once a leak has been found and fixed. Topping up without finding the leak means the gas escapes again, so we don’t recommend it.
How long does an air conditioning service take?
Expect it to take anything from an hour for a simple split system to most of a day for a larger installation. Access and the number of units decide most of the time so we will confirm the time when we book.
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.
Keeping the system healthy
Looking after it is simple, and it helps at the next service:
- Clear leaves and debris from around the outdoor unit
- Hold on to every service report
- Keep the filters clean between visits
After the service, you get a record of what was done, with the checks carried out and anything we’d recommend. Keep it with the manufacturer’s paperwork so you have the whole history together.
Make sure condensate pipes outside are not crushed, blocked or buried. If the outlet is blocked, the water has to go somewhere, and that’s normally back towards the indoor unit.
Why it’s worth doing now in Mongewell
A dirty filter or coil makes the system work harder for the same result. A service puts that right with a clean, and it means the system isn’t straining through the summer. An early booking makes the visit to Mongewell easier to arrange.
Putting several jobs into one visit often makes better use of the time. Mention every unit or room you need covered, and you’ll get one fixed price.
