Air conditioning repair in Hay Street
We repair air conditioning on all the main brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. It doesn’t matter who installed it, so tell us the make and model if you know it. We’re often asked to deal with air conditioning running but not cooling and ice forming on the indoor unit or pipes, across wall-mounted split systems, ceiling cassettes and multi-split systems.
Outdoor units in a place like Hay Street can be near hedges and fields, so leaves, seeds and cobwebs on the coil are worth checking first.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

How it works
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. On site, it takes an hour or two to diagnose most faults, with the repair time depending on what we find. Seeing the property in photos first means the trip to Hay Street can be planned properly.
- You tell us the symptoms, the make and any error code.
- A diagnosis visit finds the cause with proper tests.
- You get the cause explained and a fixed price for the repair.
- With your go-ahead, we carry out the repair, recording any refrigerant work.
- We test the system in operation and leave you a note of the fault and the fix.
Before we arrive
- Make sure we can reach the consumer unit or fuse board
- Let us know if the building has a permit or sign-in process
- Tell us about parking and loading

What a repair looks like in Hay Street
The 2021 Census found about 67% of households in detached or semi-detached houses. A photo of the outdoor unit and its surroundings tells us what access the visit needs. Historic England lists about 4 buildings and structures within half a mile of the centre of Hay Street, including The Cottage (grade II). Should a unit ever need replacing on a listed building or in a conservation area, ask us about consent first.
Schools such as Jenyns First School and Nursery can report a fault on the 24/7 line and have non-urgent work done out of term. If the display shows a code, write it down: it helps narrow down the fault.

What happens if it’s left?
The rules on refrigerant affect repairs. R410A systems can still be repaired legally, though the GB phase-down is making R410A harder and dearer to buy, so for older systems we compare the cost of a repair with a replacement. Dealing with it now is normally simpler than a breakdown later.
A single unit or a whole estate, the quote is built the same way: what needs doing, how we get to it and what it needs. The price is fixed before work begins, and the quote sets out the VAT.

What air conditioning won’t do
A few issues sit outside what this work can do:
- A supply fault outside the property
- A building problem rather than a system fault
- A unit that was never big enough for the room

What we work on in Hay Street
- Ducted systems
- Ceiling cassettes
- Wall-mounted split systems
- Multi-split systems
- VRF systems
- Heat pumps
What the work involves, system by system
Multi-split systems
Refrigerant leaks on a multi-split can be anywhere on several pipe runs. Each run is checked, then repair, pressure test and recharge.
Circuit boards and sensors
Circuit boards and temperature sensors control how the system runs. A failed sensor can make a unit stop, run oddly or show an error code, and boards can fail after a power surge or with age.
Common questions in Hay Street
Do you cover smaller places like Hay Street?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can you do air conditioning repair in Hay Street?
We do: Hay Street falls inside our working area. Tell us a little about the job and we will take it from there.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used and we’ll propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
What does the error code on my air conditioning mean?
Each manufacturer uses its own codes, and one code can have more than one cause. Tell us the code, the make and the model and we will test the system to confirm the cause.
Does servicing affect my warranty?
It depends on the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Either way, keep a record of every service.
Can I do any of the installation myself?
No, not the refrigerant side. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Why is water dripping from my indoor unit?
Most leaks come from a blocked drain, a failed pump or a unit that has dropped out of level. Ice on the coil from low airflow or low refrigerant can also melt and drip. Switch the unit off and call us on 07833 053749, or email if that’s easier.
What a customer said
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
