FAQs for Mountnessing
Is there an emergency air con repair line for Mountnessing?
Yes. Our 24/7 emergency line covers Mountnessing. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
Is Mountnessing within the area you cover?
Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Why is my air conditioning leaking water?
Usually a blocked or kinked condensate drain, a failed condensate pump or a unit that is not level. Ice that forms on the coil and melts can cause drips too. Turn it off and call 07833 053749 or fill in the contact form.
What does the error code on my air conditioning mean?
Codes differ by brand, and the same code can cover several faults. Tell us the code, the make and the model and we’ll test the system to confirm the cause.
How long does the work take?
On site, it 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.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule with a fixed price. Leak checks required by the F-gas rules can be built in for larger systems.
What warranty do I get?
The manufacturer provides it, on its own terms. Some terms depend on regular servicing by a qualified engineer so it’s worth keeping the service records.

Keeping the system healthy
A little care keeps the system in better shape. Our advice:
- Let any ice thaw before the engineer arrives
- Only let an F-Gas qualified engineer work on the refrigerant
- Check the filter, the mode and the set temperature before calling us
If parts are needed, we tell you what’s on order and book the return visit with you. We do not promise dates we can’t control and we will keep you updated.
Use the system sensibly. Moderate settings and a closed room mean less strain and the system doesn’t have to work as hard.
What air conditioning repair can’t fix
To be straight with you, some problems need a different answer:
- A system that was undersized for the room in the first place (that needs a bigger system, not a repair)
- A refrigerant fault on an R22 system (new R22 can’t be used for servicing, so replacement is usually the answer)
- An old system with obsolete parts
Not sure which it is? You can ring us on 07833 053749 or email us and we will tell you honestly before booking.

What you can do yourself, and what needs us
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 phone us on 07833 053749 or write to us at info@aircondoctor.co.uk.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
