- Weaker cooling than last year
Looking after your system
How well a system lasts depends on use and care. We suggest:
- Shut doors to the room so the system is not cooling the whole house
- Leave space around the outdoor unit for air to flow
- Report drips, smells or noises early
If you’d rather not keep track of service dates yourself, ask about a maintenance contract. We agree the visits and the cost up front so you don’t have to remember.
Act on the early signs. Odd noises, smells and drips are cheaper to sort out before they grow than after a breakdown.
Air conditioning servicing for homes and businesses in Cold Harbour
Whether a leak check is required depends on how much refrigerant the system holds and which refrigerant it is. Under the GOV.UK rules, 5 to under 50 tCO2e means a leak check at least every 12 months, and 50 to under 500 tCO2e means every 6 months. We work out where your system sits and check it accordingly. The work covers wall-mounted split systems, multi-split systems and ceiling cassettes, and people most often call us about new noises from the indoor or outdoor unit and air conditioning that isn’t cooling as well as it did.
Around Cold Harbour, outdoor units sit close to gardens and greenery, where seeds and leaves collect on the coil. A yearly clean keeps the system working well.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

What else we do in Cold Harbour
Why act early in Cold Harbour
Servicing is planned, priced and booked at a time that suits you. A breakdown arrives without warning and that makes a planned service the simpler way to look after the system. Small faults tend to grow, so it’s worth dealing with them early.
Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a system working harder than it should costs more to run. If you are not sure what’s needed, phone 07833 053749 or send an email for straight advice and a fixed price.
Why us?
- We work on all the leading brands
- We reply to enquiries the same working day

Air conditioning servicing around Cold Harbour
Central Cold Harbour is inside a conservation area. About 4 listed entries lie within half a mile of central Cold Harbour, Folly Cottage (grade II) among them. We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that. About 47% of homes across Cold Harbour and its surrounding area date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures, and the 2021 Census found about 70% of households in detached or semi-detached houses. Wall bracket, ground pad or flat roof: knowing where the outdoor unit is saves time on the day.
Most homes book one service a year; busy offices and shops may want more. Site managers at schools like Knowl Hill Church of England Primary Academy can have the site’s units serviced during a holiday.

How we price air conditioning servicing
The diagnosis comes before the price. The main factors are:
- A single visit or a regular plan
- Whether the existing supply is suitable
- How easy the units are to reach
One room or a whole building, we price it on the same basis: the work involved, the access and the equipment. The price is fixed before any work starts, and the quote sets out the VAT.
Asking for a quote
When you contact us, it’s useful to have:
- Any previous service or F-Gas records
- A few photos of the room and the wall the unit is on, or will go on
- Where the outdoor unit is, or where you’d like it
Quotes do not take long. Call or email with a few details and we’ll come back to you the same working day. If we need to see the property first, we book a survey at a time that works for you.
What we do, step by step
You don’t need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and the rest is down to us. At the end, we tidy up and run through the work with you. Work in Cold Harbour is booked in advance at a time that suits you.
- First, we agree a time and confirm the cost of the service.
- The engineer runs the system and checks how it’s performing.
- Then the cleaning: filters, coils, fan and the drain line.
- The electrics, controls and refrigerant performance are checked, with a leak check where required.
- We run the system again and leave you a service record.
Getting ready for the visit
- Let us know if the units are on a roof, a high wall or in a locked area
- Tell us about parking and loading
- Tell us about any building rules, permits or sign-in

Advice
Cold Harbour: your questions answered
Is Cold Harbour in your area for air conditioning servicing?
We do: Cold Harbour falls inside our working area. Tell us a little about the job and we will take it from there.
Does my air con in Cold Harbour need a yearly service?
A yearly visit is right for most households. Larger systems holding 5 tonnes CO2 equivalent or more also need a leak check at least every 12 months under the F-gas rules.
When will I hear back?
You will hear from us the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
Do you work on all makes?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and tell you why.
Why use an F-Gas certified company?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before booking anyone and we’ll gladly show you ours.
Which accreditations do you hold?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
How long will the engineer be here for the service?
As a guide, it takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. Ducted units in ceiling voids and outdoor units in awkward places can add time, and we’ll tell you in advance.

“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.”
