About our air conditioning servicing in Coldharbour
Every hour, an indoor unit draws the room’s air through its filter and over its coil again and again. Whatever is in the air, from dust to pet hair, collects on the filter and coil. A service clears it away, letting air pass through the unit properly and the condensate drain away. If you’re dealing with new noises from the indoor or outdoor unit and a unit showing a fault code, we can help.
Around Coldharbour, outdoor units sit close to gardens and greenery, where seeds and leaves collect on the coil. A yearly service clears them.
Warranty periods vary by brand and by product. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

System by system
Refrigerant performance and leak checks
The law requires leak checks once a system reaches 5 tCO2e, at least yearly up to 50 tCO2e and every 6 months from 50 to under 500 tCO2e. Hermetically sealed equipment holding less than 10 tCO2e doesn’t need them.
Indoor and outdoor coils
Coil fins are thin and easily flattened. We note any damage and tell you if it’s affecting performance.
What owners can safely do
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.

A photo of the outdoor unit and its surroundings tells us what access the visit needs. Coldharbour’s centre falls inside the Coldharbour, Hildenborough Conservation Area.

Aftercare tips
Systems last better with the right care. We suggest:
- Rinse the indoor unit filters every few weeks when the system is in heavy use
- Shut doors to the room so the system isn’t cooling the whole house
- Make sure the condensate outlet can drain
Once we’ve gone, use the system as normal and see how it performs. If anything seems off, give us a ring on 07833 053749 or use the quote form and we’ll look into it.
Check that the condensate pipe outside can still drain. If the outlet is blocked, the water has to go somewhere, and that’s usually back towards the indoor unit.
Coldharbour: your questions answered
Does my air con in Coldharbour need a yearly service?
A yearly visit is right for most households. Some manufacturers’ warranty terms ask for regular servicing, so it’s worth keeping the records.
Do you cover smaller places like Coldharbour?
We do. Villages and hamlets get the same service as the bigger towns. A few pictures and the postcode are enough to get things started.
What does an air con service involve?
Both the indoor and outdoor units are checked and cleaned: filters, coils, drains and fans, then the electrics, the controls and how the refrigerant circuit is performing. You get a record of the visit.
Do you protect the property while you work?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
Is a regas part of an air conditioning service?
The service checks how the refrigerant circuit is performing, but does not include adding gas. If it’s low, a leak repair comes first and the regas follows with a fixed price for each step.
Do you do service contracts for air con?
We do. A contract sets out how often we visit and what each visit covers with the price fixed when you accept the quote. It suits anyone who would rather not track service dates.
Can I do any of the installation myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
A customer’s words
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
