Air conditioning repair in Essendon, done properly
A diagnosis call-out is from £75 + VAT. When the cause is found, the repair is priced before anything else is done, so you can decide with the facts in front of you. The work covers ducted systems, ceiling cassettes and multi-split systems, and the jobs we see most are water dripping from the indoor unit and rattling, buzzing or grinding noises.
A visit to Essendon is planned so we can usually finish in one go, though some parts have to be ordered from the manufacturer.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

Honest limits
Air conditioning repair cannot fix everything, and we will tell you before work begins. It won’t put right:
- A leak on an old R22 system
- A unit whose parts are no longer made (replacement may be the only option)
- No power to the building at all
If in doubt, give us a ring on 07833 053749 and we’ll say what we think before you book.
Parts of the system we cover

System by system
Condensate drains and pumps
The drain is cleared, the pump tested and the fall checked, so the water goes where it should. Failed pumps are replaced and test it before we leave.
VRF systems
VRF systems link many indoor units to shared outdoor units, often across a whole building. We use the system’s fault history and codes, then test to confirm, and repairs are priced before they go ahead.
Questions from Essendon
Is Essendon in your area for air conditioning repair?
Yes, Essendon is within the area we cover. Tell us a little about the job and we will take it from there.
Is there an emergency air con repair line for Essendon?
Yes: ring the emergency line, day or night, from anywhere in Essendon. Say what the system is doing and whether it shows a code, and we’ll advise on the next step.
My system uses R410A. Can it still be repaired?
Yes. Repairing and recharging existing R410A systems is still legal. R410A is getting scarcer and dearer to buy as the GB phase-down tightens and we talk through repair against replacement for older systems.
Why isn’t my air con cooling?
It can be anything from a dirty filter to a refrigerant leak. Diagnosis confirms the cause, then give you a fixed price to fix it.
Can you set up regular servicing?
Yes. Send details of the systems and how they’re used and we will propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
How quickly will you reply?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
What does an air con repair cost?
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. The cost depends on the fault, the parts and access to the units.

Why act early in Essendon
Small faults rarely stay small. A blocked drain becomes water damage, and a slow leak drains the refrigerant until the compressor is working far harder than it should and early diagnosis typically keeps the repair simpler. Waiting rarely makes an air conditioning problem smaller.
Typical ranges are on our prices page, but each job is priced on what it involves. Call for a fixed-price quote, and we’ll talk you through it.
