Air con servicing in Heathrow

How we handle air conditioning servicing in Heathrow
Servicing does not mean topping up refrigerant. The refrigerant circuit is sealed, so a system that’s short of gas has a leak somewhere. Where the checks suggest gas has been lost, the right step is to find the leak, and we will set out how. If the problem is air conditioning that isn’t cooling as well as it did and systems that need a 6 or 12-monthly leak check, we can sort it out.
Most systems around Heathrow need servicing once a year, best done before summer.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

How the visit works
Think of the visit in three stages: look, put right and sign off. First we check the system or the space against the plan, then we do the work, and finally we test, record and explain. Most of the time goes on the middle part, which takes an hour or so for a single wall-mounted unit, longer for a multi-split system. For a place like Heathrow, the timing is set with you and the travel is our side of the planning.
- We start with the details of the system and anything you’ve noticed.
- Inside, the filters, coil and drain tray of each indoor unit are cleaned.
- The outdoor unit gets its own clean, with leaves and debris cleared away.
- Electrical connections, controls and refrigerant performance are tested.
- Anything we find is explained, with a fixed price if it needs a repair.
Preparing for the visit
- Clear a path to the units and the space around them
- Make sure someone can let us in at the agreed time
- Dig out any previous service or F-Gas records

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.

Why deal with it now?
A service can find a worn part or a loose connection while the system is still running. Waiting until the unit stops means dealing with it on the hottest day of the year. A system that is left with a fault, or without a service, normally costs more to run.
A single unit or a whole estate, the quote is built the same way: the work involved, the access and the equipment. The price is fixed before work begins, with VAT shown clearly.

FAQs for Heathrow
How often do you service systems in Heathrow?
A yearly visit is right for most households. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.
Will you come out to Heathrow?
Yes. Heathrow is within the area we cover across London and the South East. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
When will I hear back?
You’ll hear from us the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
Do you work on systems someone else installed?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
Who has to arrange F-Gas leak checks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
How long will the engineer be here for the service?
A typical service takes anything from an hour for a simple split system to most of a day for a larger installation. Units that are hard to reach can take longer, and we’ll tell you in advance.
Can I fit air conditioning or a heat pump myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
What air conditioning servicing cannot fix
Some problems need a different service or another trade:
- Parts that have failed and need replacing
- A system short of gas because of a leak
- A unit that was undersized when it was chosen
Not sure which it is? You can phone us on 07833 053749 or use the quote form and we’ll tell you honestly before booking.

What a customer said
“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.”
