Air conditioning servicing for homes and businesses in Sandon
For an annual service, the price is £95–£150 + VAT, confirmed before the visit is booked. Larger systems with several indoor units, ducted units or commercial plant are priced on their details. Either way, you know the cost before the engineer arrives. We’re often asked to deal with warning lights on the indoor unit and a musty or damp smell when the unit starts, across wall-mounted split systems, multi-split systems and ceiling cassettes.
Around Sandon, outdoor units sit close to gardens and greenery, where seeds and leaves collect on the coil. A yearly clean keeps the system working well.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order and each visit is recorded.

Your questions about air conditioning servicing in Sandon
Is Sandon within the area you cover?
Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Does my air con in Sandon need a yearly service?
For most homes, once a year. Some manufacturers’ warranty terms ask for regular servicing, so it’s worth keeping the records.
Can I do the refrigerant work myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine, on all the main brands. Send us the make and model, and any records you have.
Will I get records for the system?
Yes. It’s your proof of what was done: the date, the work, and any refrigerant added or recovered.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is written up and F-Gas records kept where they apply.
Do you protect the property while you work?
Floors and furniture near the work are covered with dust sheets before any work starts, and the area is kept tidy throughout. At the end, we clear up and show you what we’ve done.
What happens on the day
We keep the work area tidy as we go, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. The visit takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. For a place like Sandon, the timing is set with you and the travel is our side of the planning.
- First, we agree a time and confirm the cost of the service.
- The engineer runs the system and checks how it’s performing.
- Filters, coils, fans and drains are cleaned and cleared.
- We check the wiring, controls and refrigerant circuit, and leak check systems that need it.
- A final test run follows, then you get the service record.
Preparing for the visit
- Tell us about parking and loading
- Let us know if the units are on a roof, a high wall or in a locked area
- Move furniture away from the wall where we will be working

Common problems we fix in Sandon
Vibration and temperature changes can loosen electrical connections over time. A loose connection can cause faults that come and go, so the engineer checks them as part of the service.
Keep an eye out for these signs:
- Warning lights on the indoor unit
- A musty or damp smell when the unit starts
- Humming, rattling or squealing from the system
Site managers at schools like Sandon Junior Mixed and Infant School can have the site’s units serviced during a holiday.
Before you book anyone
- Who does the electrical work, and whether they can certify it
- Whether you get F-Gas records where refrigerant is involved
- Whether they looked at the job before pricing it

After we have gone
After the visit, a few habits help:
- Leave space around the outdoor unit for air to flow
- Book the service at least once a year
