What happens on the day
Testing is the last part of the visit wherever the system can be switched on. Then we explain what was done and answer your questions, and anything that needs a follow-up is pointed out there and then. The visit takes an hour or two to diagnose most faults, with the repair time depending on what we find. A note on how to find the property and where to park makes a visit to Astwood easier.
- You describe the fault, the make and any error code, ideally with a photo.
- At the property, readings and tests narrow the problem down to its cause.
- Once the cause is found, we explain it and fix the price for the repair.
- 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.
Before we arrive
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Name a contact who can meet us at the agreed time
- Let us know where the consumer unit is

Advice
Air conditioning repair in Astwood, done properly
Diagnosis call-outs start from £75 + VAT. Once we know the cause, you get a fixed price for the repair before any work goes ahead, so you can decide with the facts in front of you. If the problem is a flashing light and a system that won’t run and a system that won’t switch on, we can sort it out.
Around Astwood, repairs tend to be home systems, garden rooms and a few businesses. A photo of the unit’s label and a description of the fault help us plan.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

What else we do in Astwood
Common problems we fix in Astwood
When the fan runs but the air is not cold, there are some common causes: dirty filters, wrong settings, a blocked outdoor unit, a sensor or board fault, or a refrigerant leak. Diagnosis narrows it down.
Reasons to give us a call include:
- A system that won’t switch on
- A noisy indoor or outdoor unit
- An error code or flashing light on the unit
A unit that keeps tripping or showing the same code is worth a proper diagnosis.
Comparing quotes
- What records you get at the end
- Whether they looked at the job before pricing it
- Whether extra work needs your approval first
How we price air conditioning repair
Your quote is based on your property. We consider:
- How far the pipework has to run, and where
- What kind of system it is
- A single visit or a regular plan
Putting the work off seldom saves money. Small problems, from blocked filters to slow leaks, tend to get worse, and a struggling system uses more electricity to do less. If you’re unsure, phone 07833 053749 or drop us a line for straight advice and a fixed price.
Asking for a quote
Good pictures often save a visit. Try to include:
- Any error code or flashing light on the display
- A photo of the consumer unit with the cover closed
- Wide photos of the room or the existing unit
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and simple jobs can often be priced without a visit.

Astwood: your questions answered
Who do I call if my air conditioning fails in Astwood out of hours?
The emergency line is open around the clock, and Astwood is one of the places it covers. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
Is Astwood within the area you cover?
Yes, smaller places are covered as well as towns. A few photos and the postcode are enough to get things started.
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 will work out which band applies to yours.
Does servicing affect my warranty?
It can, for some brands. Read the manufacturer’s terms, or send us the make and model and we will explain them, and book the service at the interval they recommend.
How soon will you get back to me?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.
What can I do with an old R22 system?
Most of the time, we recommend replacement. New R22 cannot be used to service systems, and parts for older units are getting harder to find, so we’ll quote for a modern replacement and explain why.
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. A fixed-price quote follows.
What happens if it’s left?
Refrigerant supply is changing. Repairing and recharging existing R410A systems is still legal, but R410A is getting scarcer and dearer to buy as the GB phase-down tightens and we weigh that up when we advise you. Dealing with it now is normally simpler than a breakdown later.
No two properties are the same, so each one gets its own fixed-price quote. The equipment, how we reach it, the route between units and the work needed all make a difference.
