Different systems, different jobs
Multi-split systems
Refrigerant leaks on a multi-split can be anywhere on several pipe runs. Each run is checked before the system is repaired, tested and recharged.
VRF systems
In a VRF system, many indoor units share outdoor plant. We use the system’s fault history and codes, then test to confirm and the repair is priced before work begins.

What happens if it’s left?
If your system uses R22, the options are narrower. R22 depletes the ozone layer, and servicing with new R22 isn’t allowed, which usually makes replacement the sensible route after a refrigerant fault. We explain why and quote for a new system if that’s the right answer. Small faults tend to grow, so it’s worth dealing with them early.
Whatever the property, the quote works the same way: what’s needed, how we reach it, the parts and the labour. Call for a fixed-price quote and we will explain each part.

What happens on the day
You don’t need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and the rest is down to us. Before we leave, the area is tidied and we explain what we have done. We plan the visit to Sopwell from the survey or your pictures.
- It starts with the symptoms: what the unit is doing, the make and any code on the display.
- At the property, readings and tests narrow the problem down to its cause.
- Nothing is repaired until you’ve heard what’s wrong and agreed a fixed price.
- With your agreement the part is replaced or the fault put right, and refrigerant work goes in the F-Gas log.
- The system is run and checked in every mode, and we tell you about anything else we noticed.
How to prepare
- Make sure someone can let us in at the agreed time
- Keep pets out of the rooms we are working in
- 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 before any work starts.

Sopwell: your questions answered
Do you cover Sopwell for air conditioning repair?
Yes. Sopwell is one of the places we cover. To start, call us on 07833 053749 with a few photos.
Is there an emergency air con repair line for Sopwell?
Yes. Our 24/7 emergency line covers Sopwell. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is written up, with F-Gas records where refrigerant work is involved.
How long does the visit take?
The work itself takes an hour or two to diagnose most faults, with the repair time depending on what we find. Bigger or more complicated systems take longer, and we will tell you what to expect.
Is there a survey before the work?
Yes. We always look before we price, on a survey, or from your pictures and details where the job is simple. Then you get a fixed-price quote.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Do I need to service the system to keep the warranty?
That depends on the brand. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim and we’ll tell you what your brand asks for.
