Air conditioning servicing in Hook's Cross
A service is not the same as a regas. The refrigerant circuit is sealed, so a system that is 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’ll set out how. We are often asked to deal with smells coming from the indoor unit and frost or ice on the refrigerant pipes, across multi-split systems, VRF systems and air-to-air heat pumps.
In a village like Hook's Cross, outdoor units often face hedges, fields or gardens, so leaves, seeds and cobwebs collect on the coil. A yearly service clears them.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

Managing agents and facilities teams in Hook's Cross
Portfolio owners often want one contractor and one number. We work across London and the South East, so a run of properties can go into one programme and kept to a regular schedule.
Bigger systems bring extra duties: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We can arrange it, prepare the system for it and fix what it finds.

What else we do in Hook's Cross
Common problems we fix in Hook's Cross
Condensate has to drain away from every indoor unit. Sludge and debris can block the tray, the pipe or the pump, and the water then has nowhere to go but out of the unit.
Common reasons people call us are:
- A system that struggles to cool on warm days
- Systems that haven’t been serviced for a while
- Water dripping from the indoor unit
If you look after a school such as Barnwell School, servicing is easiest in the holidays.

Listed buildings are part of the picture here: about 4 within half a mile of the centre, such as Staples Farmhouse (grade II*). Should a unit ever need replacing on a listed building or in a conservation area, ask us about consent first. About 54% of homes in the Hook's Cross area date from 1945 to 1972, according to Valuation Office Agency council tax records, and about 55% of households live in terraced houses, according to the last census (2021). In a terrace, the route to the back garden decides how the visit is planned.
Spring is a good time for a service, before the system is needed for cooling.

Different systems, different jobs
Maintenance contracts
For businesses, a contract keeps servicing and any required leak checks on schedule, with records kept for each visit.
Indoor and outdoor coils
Outside, the coil gives off or picks up heat. Leaves, dirt and debris clog the fins, so we clean it and clear the area around the unit.
How it works
Each visit follows the same order: agree the plan on site, protect the area, carry out the job, check the system and explain it all to you. The visit itself takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. Visits to Hook's Cross are agreed with you in advance and planned so the job can be finished in one trip where possible.
- 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.
- The outdoor unit is cleaned and checked, and debris cleared from around it.
- We test the electrics, the controls and how the refrigerant circuit is performing.
- If a repair is needed, you hear why and what it costs before anything is done.
How to prepare
- Let us know where we can park and unload
- Name a contact who can meet us at the agreed time

FAQs for Hook's Cross
Is Hook's Cross within the area you cover?
Yes, smaller places are covered as well as towns. A few pictures and the postcode are enough to get things started.
Can you do air conditioning servicing in Hook's Cross?
Yes. We work across London and the South East from our base in East Grinstead, and Hook's Cross is part of that. Get in touch with the details and we reply the same working day.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
How soon will you get back to me?
The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
What does an annual air con service cost?
From £95 to £150 + VAT for the annual service, confirmed before we book. If the service finds a fault, we price the repair separately and only go ahead if you agree.
How long will the engineer be here for the service?
It takes a short visit for one split system, longer for multi-split, ducted or commercial plant. Access and the number of units decide most of the time so we will confirm the time when we book.
Do you provide F-Gas records?
Yes. Every visit is written up, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
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.”
