About our air conditioning servicing in Underhill
Air conditioning pulls room air through a filter and across a cold coil many times an hour. Whatever is in the air, from dust to pet hair, collects on the filter and coil. A service clears it away, so the system can move air properly and the drain can do its job. If you are dealing with humming, rattling or squealing from the system and iced-up coils or pipework, we can sort it out.
In Underhill, a business system may need a leak check by law as well as a service, depending on its refrigerant charge. The check is recorded, with the next date noted.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

Keeping systems in Underhill running
London outdoor units collect city dust and grime, so the outdoor coil gets particular attention on a service. Draw a one-mile circle round the middle of Underhill and it takes in 3 conservation areas. Church of St John the Baptist, listed at grade II*, is one of roughly 13 protected buildings and structures in the half-mile around Underhill’s centre. We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that.
Site managers at schools like St Catherine's RC School can have the site’s units serviced during a holiday. Most homes book one service a year; busy offices and shops may want more.

Before you call an engineer
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and ring us on 07833 053749.
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. If you need something moved, we can quote for it.
Honest limits
We will always give you a straight diagnosis, so here’s what air conditioning servicing won’t do:
- Parts that have failed and need replacing
- A system that is too small for the room it serves
- Poor original installation, such as drains without a proper fall
If in doubt, phone 07833 053749 or drop us a line and we’ll say what we think.
Parts of the system we cover
- Multi-split systems
- Air-to-air heat pumps
- Ducted systems
- Ceiling cassettes
- Wall-mounted split systems
- VRF systems
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. On arrival, the engineer compares the job with the survey, your photos or the details you gave us. Anything unexpected is raised with you before we go further. From there, the work takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. Some blocks in Underhill need contractor details in advance, so tell us what your building needs.
- We book a time that suits you and confirm the price.
- Before any cleaning, the system is run so we can see how it behaves.
- Filters, coils, fans and drains are cleaned and cleared.
- The electrics, controls and refrigerant performance are checked, with a leak check where required.
- We run the system again and leave you a service record.
Before we arrive
- Clear the space around the indoor unit, or where it will go
- Keep pets and children away from the work area
- Let us know if the building has a permit or sign-in process
Ask for a quote
VAT is set out clearly on every quote, and the rate that applies to your job is stated. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it on the quote. For a fixed-price quote, phone 07833 053749, or email if that’s easier.

Filters
The filter is the first line of defence for the indoor unit. On a service, they’re cleaned and checked for tears and we’ll say if one needs replacing.
Condensate drains and pumps
Slime and debris build up in drain trays over time. Cleaning them helps with drips and with musty smells.
Your questions about air conditioning servicing in Underhill
How often do you service systems in Underhill?
Usually once a year for homes, more often for busy business systems. Some manufacturers’ warranty terms ask for regular servicing, so it’s worth keeping the records.
Is Underhill in your area for air conditioning servicing?
Yes, Underhill is within the area we cover. Tell us a little about the job and we will take it from there.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up and F-Gas records kept where they apply.
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, and we’ll give you an idea when we book.
Which accreditations do you hold?
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.
Do you look at the job first?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the job needs and how to do it and the fixed price is built on it.
Which brands do you work with?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
