Air Conditioning Servicing in Booker

About our air conditioning servicing in Booker
We are asked to service systems for many different reasons: smells at start-up, a unit that struggles on hot days, drips from the indoor unit, or a service that is overdue. Whatever the reason, the visit follows the same thorough checks. If the problem is noisy fans or rattling from the outdoor unit and no service record for the last year or more, we can help.
We book services in Booker at a time that suits you, and most single systems take an hour or two.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

When to call us in Booker
The indoor coil is cold and wet when the system is cooling. Dust sticks to a wet surface, and over time the coil and drain tray can get dirty enough to smell.
Keep an eye out for these signs:
- A unit showing a fault code
- Condensate leaking into the room
- New noises from the indoor or outdoor unit
Booking before the first hot spell means the system is ready when you need it.
Questions to ask before booking
- What records you get at the end
- Whether the company is F-Gas certified, and whether you can check it
- Whether the quote is a fixed price

Booker questions
Will you come out to Booker?
We do. Villages and hamlets get the same service as the bigger towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is Booker in your area for air conditioning servicing?
Yes, Booker is within the area we cover. Tell us a little about the job and we’ll take it from there.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for problems that cannot wait for a planned visit. Call 07833 053749 and tell us what’s happened.
Is a regas part of an air conditioning service?
Not as a routine part of the service. If a system has lost refrigerant, it has leaked from somewhere. We check the refrigerant performance, and if we suspect a leak we explain how it can be found and repaired.
How much does an air conditioning service cost?
It’s £95–£150 + VAT for an annual service. Where the system is larger or more complex, we price it from the details you give us, so the cost is fixed before we start.
How long will the engineer be here for the service?
As a guide, it takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. Units that are hard to reach can take longer, and we will tell you in advance.
Why does F-Gas certification matter?
Certification shows a business is approved to work on systems that hold F gas refrigerant. That is not optional: it’s required by law, and we hold it.
Why deal with it now?
If your system needs F-gas leak checks, they are not optional. Missing one leaves you without the check and the record and it’s far easier to stay on schedule. A system that is left with a fault, or without a service, normally costs more to run.
Putting several jobs into one visit often makes better use of the time. Mention every unit or room you need covered and we will price it together.

Honest limits
Not every problem is solved by air conditioning servicing, and we’ll tell you before we start. It does not solve:
- Parts that have failed and need replacing
- Heat gains the system was never sized for
- A refrigerant leak, which needs finding and repairing, not topping up
If you are not sure, just phone us on 07833 053749, or email if that’s easier and we will give you a straight answer before you book.
Where we work
- Wall-mounted split systems
- Ceiling cassettes
- Ducted systems
- Multi-split systems
- VRF systems
- Air-to-air heat pumps
How it works
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. The visit takes anything from an hour for a simple split system to most of a day for a larger installation. Seeing the property in photos first helps us plan the trip to Booker.
- When you book, we ask what make it is, how many rooms it serves and whether anything seems wrong.
- The engineer switches the system on and checks how it behaves before taking anything apart.
- Filters are cleaned, coils treated and the drain tray and pipe cleared.
- We check the electrics, the controls and how the refrigerant circuit is performing, and carry out a leak check where the rules call for it.
- Before leaving, the engineer writes up the visit and talks you through anything worth knowing.
Getting ready for the visit
- Dig out any previous service or F-Gas records
- Mention any managing agent or landlord rules we need to follow
- Let us know if the units are on a roof, a high wall or in a locked area
