Advice
Air conditioning servicing in Harrow on the Hill, done properly
Servicing covers both halves of the system: the indoor units in the rooms and the outdoor unit outside. Filters and coils are cleaned, the drain is cleared, and the electrics, controls and refrigerant performance are all checked. We carry out air conditioning servicing for homes and businesses in Harrow on the Hill and the rest of Greater London, for most leading brands. The work covers multi-split systems, ducted systems and VRF systems, and the jobs we see most are condensate leaking into the room and air conditioning that isn’t cooling as well as it did.
In a London area like Harrow on the Hill, many systems run hard in summer and for heating in winter, so a yearly service keeps them efficient. In London, outdoor coils collect dust, grime and leaves, which a service clears.
Any work on the refrigerant circuit is recorded: 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.

Common questions in Harrow on the Hill
Do you cover Harrow on the Hill for air conditioning servicing?
Yes. We work across London and the South East from our base in East Grinstead, and Harrow on the Hill is part of that. Just phone 07833 053749 or email us with a few details.

The easiest way is to ring 07833 053749 or fill in the contact form with a few details and pictures. Simple jobs can be priced from photos; otherwise we arrange a site survey and then give you a fixed-price quote.
Will I get records for the system?
Yes. Each visit is written up, and any work on the refrigerant circuit goes in the F-Gas records. Keep them with the manual and the warranty documents.
Do you work on systems someone else installed?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used, and we’ll suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.
How long does the work take?
That depends on what’s involved, but as a guide it takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. We’ll give you a firmer idea when we quote.
What does F-Gas certified mean?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. It’s worth checking before you book, and we’re happy to show ours.
Why deal with it now?
Smells from an indoor unit tend to come back each time it runs. The cure is cleaning where the dirt has built up, rather than masking it. Planning ahead in Harrow on the Hill means you choose the date, not the weather.
Height, access and the distance between the indoor and outdoor units all affect the cost. Each of those is built into the quote, and the price is fixed before any work starts.
Why book with us
- Every job looked at before it’s priced
- A 24/7 emergency line
- F-Gas company certification
- Warranty terms set out brand by brand
What owners can safely do
Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
Don’t move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. Ask us to quote for a move instead.

“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.”
