How we handle air conditioning servicing in Donnington
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 Donnington and the rest of West Sussex, whatever the make. We are often asked to deal with humming, rattling or squealing from the system and weaker cooling than last year, on air-to-air heat pumps, wall-mounted split systems and VRF systems.
Several units at a home near Donnington can be serviced in one visit.
The records are your system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

What we do, step by step
Each visit runs to the same pattern: agree the plan on site, put the dust sheets down, do the work, check the system and explain it all to you. The visit itself takes anything from an hour for a simple split system to most of a day for a larger installation. For a village like Donnington, tell us about narrow lanes, gates and parking when you book.
- It begins with a few questions about the make, the rooms served and any symptoms.
- The indoor units are opened up and the filters, coils and drain trays cleaned.
- The outdoor unit is cleaned and checked, and debris cleared from around it.
- 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
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Let us know if the units are on a roof, a high wall or in a locked area
- Have the make and model of any existing unit to hand

Common questions in Donnington
Is the coast a problem for outdoor units in Donnington?
It can, as Donnington is within about 3 miles of the sea, where salt in the air is hard on coils and fixings. A yearly service that rinses and checks the outdoor coil matters more near the sea.
Is Donnington within the area you cover?
Yes, smaller places are covered as well as towns. Send a few details and pictures, and we reply the same working day.
Do you provide F-Gas records?
Yes. Every visit is written up, including F-Gas records for any refrigerant work. File them with the system’s paperwork.
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 any work starts.
Does the manufacturer’s warranty require regular servicing?
Each manufacturer sets its own terms. Some warranties may include conditions about regular servicing so it’s worth reading yours. We can explain the terms, and each visit is recorded.
Why use an F-Gas certified company?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before you book and we’ll gladly show you ours.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us in Donnington and across West Sussex. Tell us who should receive the paperwork.
Leave it or put it right?
A musty smell from the system is rarely something that clears on its own. The cure is cleaning where the dirt has built up, rather than masking it. A system that is left with a fault, or without a service, typically costs more to run.
Putting several jobs into one visit can make for a more efficient booking. Mention every unit or room you need covered and we will price it together.

When to call us in Donnington
A slow leak can go unnoticed for a long time. Performance drops slowly and only becomes obvious when the weather is at its extreme.
Look out for these signs:
- A unit showing a fault code
- A system that struggles to cool on warm days
- Smells coming from the indoor unit
Site managers at schools like Chichester High School For Girls can have the site’s units serviced during a holiday.

Keeping systems in Donnington running
Donnington is within about 3 miles of the coast. Coastal outdoor units are worth checking for corrosion at every service.

The Parish Church of St George, listed at grade I, is one of roughly 12 protected buildings and structures in the half-mile around Donnington’s centre.

What the work involves, system by system
Indoor and outdoor coils
The indoor coil is where the air is cooled or warmed. We clean it so air can pass through the fins and heat can pass in and out, and we look for damage or corrosion.
Filters
Certain indoor units carry additional filters alongside the main ones. They’re checked too, and we explain what the manufacturer suggests.
