Coldharbour questions
Is Coldharbour in your area for air conditioning servicing?
Yes. Coldharbour is one of the places we cover. Tell us a little about the job and we’ll take it from there.
Is Coldharbour within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. Send a few details and photos, and we reply the same working day.
How often should air conditioning be serviced?
At least once a year is a sensible routine for most systems. Systems that work hard, such as those used for heating or in busy workplaces, may benefit from more frequent visits, and your manufacturer’s terms may set their own expectations.
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Does my air conditioning need an F-gas leak check?
Only if the system is at or above the threshold of 5 tCO2e. Plenty of small splits sit under it, as 3 kg of R32 works out at about 2.0 tCO2e. We read the charge from the label and work it out for you.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
Do you top up refrigerant during a service?
A service doesn’t include adding refrigerant. If a system has lost refrigerant, it has leaked from somewhere. We check the refrigerant performance, and if we suspect a leak we explain how it can be found and repaired.
How we handle air conditioning servicing in Coldharbour
For homes with one or two units and businesses with many, we can set up a maintenance contract. We agree the visits, what each one covers and the price with your quote, and the servicing happens on schedule. If you are dealing with noisy fans or rattling from the outdoor unit and weaker cooling than last year, we can help.
Most systems around Coldharbour need servicing once a year, best done before summer.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. That also helps where the warranty terms ask for regular servicing.

Signs you need air conditioning servicing in Coldharbour
How often a system needs servicing depends partly on how hard it works. Heat pumps used for winter heating and units in busy offices, shops or kitchens get through a lot of air and so builds up dirt more quickly.
Any of these is worth a proper look:
- New noises from the indoor or outdoor unit
- A service that’s overdue
- An unpleasant odour when the system runs
Water dripping from the indoor unit often traces back to a drain that needs clearing.

Servicing in Coldharbour: local notes
Central Coldharbour is inside the Coldharbour Conservation Area. On the National Heritage List, around 5 entries fall within 0.5 miles of the middle of Coldharbour; Christ Church (grade II) is one. For most visits that makes no difference. It only comes up when an outdoor unit has to be replaced on a protected building. VOA council tax data put about 40% of homes in and around Coldharbour before 1919, and about 76% of households live in detached or semi-detached houses, according to Census 2021 figures. Access to the outdoor unit is the one detail that most changes how a visit is planned.
A service once a year suits most home systems, and some business systems need more.

What the work involves, system by system
Maintenance contracts
The visit frequency is set around the system and how it’s used, rather than a one-size plan.
Condensate drains and pumps
Slime and debris build up in drain trays over time. A clean tray means fewer drips and fewer smells.
How it works
If the system has to be off for part of the visit, we tell you before we start so it doesn’t catch you out. For businesses, we can typically work room by room or zone by zone. On site, it takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. Rural lanes and tight entrances are worth mentioning before a visit to Coldharbour.
- We start with the details of the system and anything you’ve noticed.
- Each indoor unit has its covers lifted so the filters, coil and tray can be cleaned.
- Outside, the coil is cleaned, the fan checked and the area cleared.
- We test the electrics, the controls and how the refrigerant circuit is performing.
- Anything we find is explained, with a fixed price if it needs a repair.
Getting ready for the visit
- Arrange for someone to be there to let us in
- Move furniture away from the wall where we will be working
- Make sure we can reach the outdoor unit, or where it will go
How to get a quote
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. Then you get a fixed price so you know the cost before we begin.

Why deal with it now?
A musty smell from the system is rarely something that clears on its own. Cleaning the coil, the fan and the drain tray deals with the cause, rather than masking it. Getting the date in early helps for a place like Coldharbour.
Every job is different, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all play a part.
