Air conditioning servicing for homes and businesses in Dunsfold
People in Dunsfold book a service for all sorts of reasons: a musty smell, weak cooling, water dripping indoors or simply because it’s been a while. Whatever the reason, the visit follows the same thorough checks. Common call-outs are for drips or damp patches below an indoor unit and humming, rattling or squealing from the system, on VRF systems, ducted systems and air-to-air heat pumps.
Around Dunsfold, outdoor units sit close to gardens and greenery, so leaves, seeds and cobwebs collect on the coil. A yearly clean keeps the system working well.
Each manufacturer sets its own warranty period. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

Different systems, different jobs
Fans and electrics
We look at the wiring and terminals for anything loose or discoloured. Loose connections can cause faults that come and go, so this matters.
Indoor and outdoor coils
Room air passes over the indoor coil, which takes heat out or puts it in. Cleaning removes the dust that coats the fins and any damage is noted.
Keeping systems in Dunsfold running
Census 2021 figures found about 78% of households in detached or semi-detached houses. If the outdoor unit is high up or behind a locked gate, mention it when you book. Dunsfold’s centre is no more than about a third of a mile from the Dunsfold Conservation Area. There are 2 conservation areas within a mile of the centre of Dunsfold. Listed buildings are part of the picture here: about 24 within half a mile of the centre, such as Church of St Mary and All Saints (grade I). For most visits that makes no difference. It only comes up when an outdoor unit has to be replaced on a protected building.
Water dripping from the indoor unit often traces back to a drain that needs clearing. Booking before the first hot spell means the system is ready when you need it.

Why act early in Dunsfold
A service costs a set price and fits around your diary. A fault picks its own moment, so a planned visit is the easier option. Waiting rarely makes an air conditioning problem smaller.
The cost depends on the system and the number of rooms or units, how easy the units are to reach and the parts and time the job needs. We give you a fixed price before work begins, so there are no surprises.

Before you call an engineer
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
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 a breaker trips again after you reset it, leave it off and give us a ring on 07833 053749 or write to us at info@aircondoctor.co.uk.

Your questions about air conditioning servicing in Dunsfold
Is Dunsfold within the area you cover?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
Do you cover Dunsfold for air conditioning servicing?
Yes. We work across London and the South East from our base in East Grinstead, and Dunsfold is part of that. Just call us on 07833 053749 or fill in the contact form with a few details.
Do you protect the property while you work?
Protection goes down first: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
When is an F-gas leak check required?
The rules are based on tCO2e, which comes from the refrigerant charge and its GWP. At 5 to under 50 tCO2e, it’s at least every 12 months; at 50 to under 500 tCO2e, every 6 months. Hermetically sealed systems under 10 tCO2e are exempt.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Can I fit air conditioning or a heat pump myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s the law, not just our preference, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
Do you provide F-Gas records?
Yes. It’s the record a manufacturer or the next engineer will ask to see: the date, the work, and any refrigerant added or recovered.
What happens on the day
We keep the work area tidy as we go, with dust sheets down and offcuts and packaging cleared up. Any holes, fixings or cable routes are agreed with you before we drill. On site, it takes a short visit for one split system, longer for multi-split, ducted or commercial plant. We agree a date with you and plan the visit to Dunsfold so we arrive with what’s needed.
- 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.
- Readings are taken on the electrics and refrigerant circuit, and the controls are tried in each mode.
- If a repair is needed, you hear why and what it costs before anything is done.
How to prepare
- Dig out any previous service or F-Gas records
- Make sure we can reach the consumer unit or fuse board
- Unlock any gate, garage or side passage we need
