- Water dripping from the indoor unit
- A unit that barely blows any air
- A system that runs but doesn’t cool the room
Looking after your system
Every system needs looking after, and most of it is easy. A few tips:
- Check the filter, the mode and the set temperature before calling us
- Leave space around the outdoor unit
- Turn it off and let ice clear before the visit
After a repair, the basics matter: clean filters and a clear outdoor unit help the system run as it should. A yearly service catches problems before they become breakdowns.
Small changes are worth acting on. A drip, a new noise, a weaker airflow or an occasional error code is often the first sign of a fault, and early diagnosis typically means a smaller repair.
How we handle air conditioning repair in Old Windsor
Faults on all the leading makes are part of our everyday work, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Systems fitted by other installers are fine too, so tell us the make and model if you know it. If you’re dealing with a unit that barely blows any air and a system that won’t switch on, we can help.
Outdoor units around Old Windsor often sit near hedges, trees and lawns, and leaves or grass cuttings on the coil are a common reason for poor cooling. We check the coil early on.
Each manufacturer sets its own warranty period. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

Owner checks or an engineer?
On air conditioning, the filters in the indoor unit are normally the one part owners can clean where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.

Your questions about air conditioning repair in Old Windsor
Can you do air conditioning repair in Old Windsor?
We do: Old Windsor falls inside our working area. Just ring 07833 053749 or write to us at info@aircondoctor.co.uk with a few details.
Do you cover Old Windsor for emergency air conditioning repairs?
Yes. Our 24/7 emergency line covers Old Windsor. Say what the system is doing and whether it shows a code, and we’ll advise on the next step.
Why is my air conditioning blowing warm air?
It can be anything from a dirty filter to a refrigerant leak. Diagnosis confirms the cause and you get a fixed price before the repair.
How soon will you get back to me?
The same working day. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is the law, not just our preference, and manufacturers expect it for their warranty too. We are happy to quote for the full job, supply to commissioning.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Will skipping a service affect the warranty?
Each manufacturer decides. If servicing is in the terms, missing one could affect a claim and we’ll tell you what your brand asks for.
What happens if it’s left?
Leaving a fault seldom makes it go away. A blocked drain becomes water damage, and a slow leak drains the refrigerant until the compressor is working far harder than it should, so getting it looked at early typically means a simpler repair. A dirty or faulty system works harder and costs more to run.
Every job is different, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all play a part.

- On the diagnosis visit, the engineer tests the system rather than guessing.
- Nothing is repaired until you’ve heard what’s wrong and agreed a fixed price.
- With your agreement the part is replaced or the fault put right, and refrigerant work goes in the F-Gas log.

- Give us access to the outside wall, roof or yard where the outdoor unit sits
