Questions from Hexton
Do you cover Hexton for emergency air conditioning repairs?

Yes. Hexton is one of the places we cover. Get in touch with the details and we reply the same working day.
How does the warranty work?
The manufacturer’s warranty, on the manufacturer’s terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Can you set up regular servicing?
Yes. Tell us what you have and how it’s used and we will propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
What does F-Gas certified mean?
For refrigerant work, both the engineer and the company need the right F-gas credentials. Ask to see proof before booking anyone and we will gladly show you ours.
Which accreditations do you hold?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we’re Checkatrade members. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Will skipping a service affect the warranty?
That depends on the brand. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim, so we explain the terms on your quote.
Air conditioning repair in Hexton
A symptom is only a clue: warm air, drips and error codes can each have several causes. A unit blowing warm air might have a blocked filter, a failed sensor, a fault on the circuit board or a refrigerant leak, which is why diagnosis comes first. Typical jobs include poor airflow even with clean filters and air conditioning running but not cooling, on ceiling cassettes, heat pumps and ducted systems.
Outdoor units in a place like Hexton can be near hedges and fields, and a coil clogged with leaves or seeds is a common cause of weak cooling.
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 every service is written up.

Air conditioning repairs in Hexton: local notes
About 77% of households live in detached or semi-detached houses, according to the 2021 Census. Let us know where the outdoor unit sits and whether a ladder is needed to reach it. Central Hexton is inside the Hexton Conservation Area. About 13 listed entries lie within half a mile of central Hexton, Church of St Faith (church of England) (grade II*) among them. Day-to-day work on an existing system isn’t affected; a replacement outdoor unit on a protected building might be.
A photo of the error code and the unit’s rating label helps us plan the repair. For a school like Hexton Junior Mixed and Infant School, urgent repairs can be booked straight away and bigger work in the holidays.

Looking after it afterwards
Systems last better with the right care. We suggest:
- If there’s ice on the pipes, switch off and let it melt
- Switch the unit off if water is leaking from it
- Book an annual service after the repair
Once the fault is fixed, we test the system in operation. We check it’s cooling or heating as it should and that the fault hasn’t left anything else behind, and we tell you about anything we noticed.
Sensible use helps. Choose the right mode and a moderate set temperature, and keep doors and windows closed while it runs and the system doesn’t have to work as hard.
What you can do yourself, and what needs us
On air conditioning, the filters in the indoor unit are usually the one part owners can clean, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
When something else is needed
Before you book, it helps to know what’s not included:
- A building problem rather than a system fault
- A refrigerant fault on an R22 system (new R22 cannot be used for servicing, so replacement is usually the answer)
- A unit whose parts are no longer made (replacement may be the only option)
If in doubt, call us on 07833 053749, or email if that’s easier and we will say what we think.

How it works
Each visit runs to the same pattern: check the plan with you, put the dust sheets down, do the work, test what we’ve done and talk you through it. The visit itself takes anything from an hour or so to a full day, depending on the fault and the parts. We agree a date with you and plan the visit to Hexton so we arrive with what’s needed.
- Diagnose: test the system until the cause is clear.
- Then the prescription: what’s wrong and what it will cost to put right.
- If the repair isn’t worth doing, we say so and explain the options.
- Treat: carry out the repair, sealing any leak before refrigerant goes back in.
- The sign-off: the system tested in operation and the work recorded.
Getting ready for the visit
- Plan for pets to be kept clear during the visit
- Tell us about parking and loading
- Move furniture away from the wall where we’ll be working
