Northaw questions
How often should air conditioning in Northaw be serviced?
A yearly visit is right for most households. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.
Is Northaw 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.
What does an air con service involve?
Filters, coils, fans and the condensate drain are all cleaned and checked. We also check the electrical connections, the controls and the refrigerant performance, with an F-gas leak check where the system requires one.
Can you come out in an emergency?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we’ll agree what happens next.
Can you set up regular servicing?
Yes. We offer maintenance contracts, 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.
What accreditations do you have?
We are an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re members of Checkatrade too.
Do you look at the job first?
Yes. We always look before we price, on a survey, or from your photos and details where the job is simple. Then you get a fixed-price quote.
How we handle air conditioning servicing in Northaw
A service is not the same as a regas. Refrigerant runs in a sealed circuit and shouldn’t need adding to. Where the checks suggest gas has been lost, the right step is to find the leak, and we’ll set out how. Common call-outs are for ice forming on the pipework or outdoor unit and smells coming from the indoor unit, on multi-split systems, ducted systems and ceiling cassettes.
Around Northaw, 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. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

Servicing in Northaw: local notes
Northaw’s centre is no more than about a third of a mile from the Northaw Village Conservation Area. About 15 listed entries lie within half a mile of central Northaw, Parish Church of St Thomas a Becket (grade II*) among them. If a repair turns into a replacement on a listed building or in a conservation area, we check the planning position before changing the outdoor unit. Valuation Office Agency council tax records date about 44% of homes in and around Northaw to the post-war years, 1945 to 1972, and about 84% of households live in detached or semi-detached houses, according to Census 2021 figures. If the outdoor unit is high up or behind a locked gate, mention it when you book.
Spring is a good time for a service, before the system is needed for cooling.

The process
Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we’ve done and answer any questions, and anything that needs a follow-up is pointed out there and then. All told, the work takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. For a village like Northaw, tell us about narrow lanes, gates and parking when you book.
- First, we agree a time and confirm the cost of the service.
- Before any cleaning, the system is run so we can see how it behaves.
- We clean the filters, coils and fans and clear the condensate drain.
- 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.
Before we arrive
- Clear the space around the indoor unit, or where it will go
- Find the manual or the paperwork for the system, if you have it
- Make sure we can reach the outdoor unit, or where it will go

Indoor and outdoor coils
Coil fins are thin and easily flattened. We’ll point out damaged fins and whether they matter.
Refrigerant performance and leak checks
tCO2e is the refrigerant charge in kg multiplied by its global warming potential, divided by 1,000. As an example, 3 kg of R32 comes to about 2.0 tCO2e, while 3 kg of R410A is about 6.3 tCO2e. We check the label on your system and tell you where it sits.
What we are called out for in Northaw
Vibration and temperature changes can loosen electrical connections over time. A loose connection can cause faults that come and go which is why they’re checked on every service.
The things we’re asked about most include:
- Air conditioning that isn’t cooling as well as it did
- F-gas leak checks falling due
- Water dripping from the indoor unit
If you look after a school such as Northaw Church of England Primary School, servicing is easiest in the holidays.

A customer’s words
“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.”
