Do you cover St Mary Cray for emergency air conditioning repairs?
Yes: ring the emergency line, day or night, from anywhere in St Mary Cray. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
How much is an air conditioning call-out?
Diagnosis call-outs start from £75 + VAT. When we’ve found the fault, the repair is priced before we do it. The cost depends on the fault, the parts and access to the units.
What causes water to leak from an air conditioning unit?
Normally 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 ring us on 07833 053749 or write to us at info@aircondoctor.co.uk.
Does servicing affect my warranty?
Each manufacturer decides. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim and we’ll tell you what your brand asks for.
Why is my air conditioning icing up?
When airflow drops or refrigerant is lost, the coil gets cold enough to ice. Check the filter first, and if it’s clean, the system needs a diagnosis.
How do you keep the place clean during the work?
Floors and furniture near the work are covered with dust sheets before we start, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Air conditioning repair for homes and businesses in St Mary Cray
When air conditioning stops cooling, leaks water or shows an error code, the symptom rarely tells you the cause. Warm air can mean anything from a dirty filter to a sensor, board or refrigerant fault, so we diagnose before we repair. If you’re dealing with a unit that has lost refrigerant and drips from the indoor unit, we can help.
In a London area like St Mary Cray, a lot of the systems we repair serve flats and small offices, with outdoor units on balconies, rear walls or flat roofs. Knowing where the outdoor unit sits, and how to get to it, helps us plan the repair.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. Where yours does, a regular service with us keeps that side in order, and every service is written up.

What you can do yourself, and what needs us
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If a breaker trips again after you reset it, leave it off and ring 07833 053749, or email if that’s easier.
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.

Ice on the pipework or the indoor coil is a symptom, not the fault. It normally points to poor airflow, such as a clogged filter or a fan problem, or to a refrigerant leak. Turn it off and let the ice melt, then call us.
Common reasons people call us are:
- Rattling, buzzing or grinding noises
- A unit blowing warm air
- A system that needs topping up again
Shops and offices around St Mary Cray station often cannot wait for cooling to come back, which is what the 24/7 line is for.

What else we do in St Mary Cray
How it works
Think of the visit in three stages: look, put right and sign off. First comes a careful look at the system or the space, then the work itself, and finally everything is tested, recorded and explained. The middle part takes longest, which takes an hour or two to diagnose most faults, with the repair time depending on what we find. Parking bays, permits and roof or balcony access are the first things we ask about in St Mary Cray.
- You describe the fault, the make and any error code, ideally with a photo.
- The engineer reads the fault codes and checks the electrics, airflow, drain and refrigerant circuit.
- We explain the cause and give you a fixed price for the repair before any work goes ahead.
- 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.
Preparing for the visit
- Arrange for someone to be there to let us in
- Clear the space around the indoor unit, or where it will go
- Mention any parking restrictions near the property
How to get a quote
Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.
