How we handle air conditioning repair in Kemprow
Age alone doesn’t decide whether a repair is worth it. A fan fault on an older unit can be worth fixing, while a compressor failure may tip the balance. We look at the fault, the parts, the refrigerant and how well the system suits the room, then give you an honest view. We’re often asked to deal with a fault code on the display and poor airflow even with clean filters, across multi-split systems, wall-mounted split systems and VRF systems.
Around Kemprow, outdoor units often sit close to gardens and hedges, so leaves, seeds and cobwebs on the coil are worth checking first.
Each manufacturer sets its own warranty period. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

Honest limits
Air conditioning repair can’t fix everything, and we’d rather say so up front. It does not solve:
- An R22 system that has lost its refrigerant
- Heat gains the system was never designed for
- A unit whose parts are no longer made (replacement may be the only option)
Not sure which it is? You can phone 07833 053749 or drop us a line and we’ll tell you honestly before you book.

When air con fails in Kemprow
The 2021 Census found about 71% of households in detached or semi-detached houses. A photo of the outdoor unit and its surroundings tells us what access the visit needs. There are 3 conservation areas within a mile of the centre of Kemprow. Listed buildings are part of the picture here: about 9 within half a mile of the centre, such as Kemprow Farm House (grade II). Swapping an outdoor unit on a listed building or in a conservation area may need consent, so we will flag it if a replacement is needed.
A photo of the error code and the unit’s rating label helps us plan the repair. When cooling fails at a school like Fair Field Junior School, we can time non-urgent repair work around lessons.

Your questions about air conditioning repair in Kemprow
Who do I call if my air conditioning fails in Kemprow out of hours?
Yes. Our 24/7 emergency line covers Kemprow. Have the make, model and error code ready, and we will talk you through what happens next.
Can you do air conditioning repair in Kemprow?
Yes. Kemprow is one of the places we cover. Get in touch with the details and we reply the same working day.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Will you work on another installer’s system?
Yes. We look at it first and tell you 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?
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’ll diagnose the fault on site.
Will you make a mess?
We start with protection: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
What causes water to leak from an air conditioning unit?
In most cases, it’s the condensate system: a blocked pipe, a kinked hose or a failed pump. Switch the unit off to avoid water damage, then call us.

What happens on the day
Protection comes first: sheets over the floor and any furniture nearby and nothing is moved without asking you. After that, anything electrical is made safe and we start. The work on site takes anything from an hour or so to a full day, depending on the fault and the parts, and we tidy up before we leave. Work in Kemprow is booked in advance at a time that suits you.
- First, a few questions by phone or email about the brand, the fault and anything shown on the controller.
- On the diagnosis visit, the engineer tests the system rather than guessing.
- We explain the cause and give you a fixed price for the repair before any work goes ahead.
- The fix goes in, with any refrigerant work tested and written into the F-Gas records.
- The system is run and checked in every mode, and we tell you about anything else we noticed.
How to prepare
- Dig out any previous service or F-Gas records
- Tell us about parking and loading
- Keep pets out of the rooms we are working in

Before you call an engineer
Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and call 07833 053749, or email if that’s easier.
On air conditioning, the filters in the indoor unit are typically the one part owners can clean, if the manual says so. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
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.”
