About our air conditioning repair in Box Hill
A sealed system shouldn’t lose refrigerant, so if it’s low, there’s a leak. Simply adding gas means it will leak away again. We locate the leak, repair it, test, evacuate and recharge and write it up in the F-Gas records. If you are dealing with a unit that barely blows any air and frost on the pipework, we can help.
Around Box Hill, repairs tend to be home systems, garden rooms and a few businesses. Describe the fault and send a photo of the unit’s label so we can plan the visit.
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. It also keeps you on the right side of any warranty terms that ask for servicing.

What the work involves, system by system
Circuit boards and sensors
Testing comes before any part is replaced because swapping parts on a guess wastes money. Some parts need ordering from the manufacturer and we will explain any wait.
Condensate drains and pumps
We clear the drain, test the pump and check the fall until the condensate runs away properly. Failed pumps are replaced and test it before we leave.
What we do, step by step
The visit goes in the diary at a time that works for you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the photos you sent. If something is different, we talk it through with you before carrying on. From there, the work takes as long as the fault needs, from a quick fix to a return visit for parts. Photos of the room and the outside of the property help us plan a visit to Box Hill.
- We start with what the unit is doing, the make and any code.
- On the diagnosis visit, we test the electrics, airflow, drain and refrigerant.
- The fault is explained simply and the repair priced up front.
- Once you are happy, the repair is done and any refrigerant work recorded.
- We test the system in operation and leave you a note of the fault and the fix.
How to prepare
- Have the make and model of any existing unit to hand
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Keep pets and children away from the work area

Common questions in Box Hill
Do you cover Box Hill for emergency air conditioning repairs?
Yes. Our 24/7 emergency line covers Box Hill. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
Do you cover Box Hill for air conditioning repair?
Yes, Box Hill is within the area we cover. Tell us a little about the job and we’ll take it from there.
Do you work on systems someone else installed?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
My air con is showing an error code. What should I do?
The code is the system’s own clue to the fault, but testing confirms the cause. Write down the code and turn the unit off if it has stopped, then give us a ring on 07833 053749, or email if that’s easier.
Who is responsible for leak checks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
How long does the work take?
That depends on what’s involved, but in most cases it takes a single visit for many faults, while some repairs need a second visit once parts arrive. We will confirm it with the quote.
What does F-Gas certified mean?
Companies working on equipment that contains F gas must be certified by an approved body, and each engineer needs the right qualifications too. It’s how you know the refrigerant is being handled legally and safely.

When it’s something else
Not every problem is solved by air conditioning repair, and we will tell you before we start. It won’t put right:
- An old system with obsolete parts
- A building problem rather than a system fault
- A system that was undersized for the room in the first place (that needs a bigger system, not a repair)
If you’re not sure, just phone us on 07833 053749 or drop us a line and we’ll give you a straight answer before you book.

Pricing air conditioning repair in Box Hill
The price is fixed before any work begins. It takes into account:
- Whether we need access equipment for high-level work
- The electrical supply and whether a new circuit is needed
- The pipe route between the units
The cost depends on the type of system and how many units are involved, the access and what the work involves. We give you a fixed price before we start, so you know where you stand.
Before you get in touch
There’s no need for technical detail. Just send:
- The fuse board and where it is in the property
- The outside wall, roof or yard where the outdoor unit sits or would go
- The paperwork from the last service, if you have it
