Air conditioning repair in Harold Wood, done properly
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, which is why diagnosis comes first. The work covers multi-split systems, ceiling cassettes and wall-mounted split systems, and people most often call us about a flashing light and a system that won’t run and water leaking from the unit or through the ceiling.
We prepare for a visit to Harold Wood from the make and model you give us, and any part that needs ordering is priced before it’s fitted.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Each brand sets its own conditions, and we are happy to talk you through them.

FAQs for Harold Wood
Who do I call if my air conditioning fails in Harold Wood out of hours?
Yes. Our 24/7 emergency line covers Harold Wood. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
Is Harold Wood within the area you cover?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
My air con is showing an error code. What should I do?
An error code points us in the right direction, but it isn’t the whole answer. Write down the code and turn the unit off if it has stopped, then call 07833 053749.
Which brands do you work with?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and tell you why.
Do you provide F-Gas records?
Yes, always. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
Who is responsible for leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We will work out which band applies to yours.
How does the warranty work?
Warranty comes from the manufacturer and depends on the brand and product. Daikin, for example, gives a standard 2 years on split air conditioning, and we explain the terms for whichever brand you choose.
Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Keep to the service interval the manufacturer recommends
- If there’s ice on the pipes, switch off and let it melt
- Leave a tripping breaker off and call us
If a repair doesn’t make sense, you’ll hear it from us, with the reasons. If replacement is the better option, we can quote for it on the same visit.
Have the system serviced once a year. A service cleans the coils and drain, checks the electrics and the refrigerant circuit and catches small faults early and that is normally simpler than a breakdown repair.
How the visit works
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. All told, the work takes anything from an hour or so to a full day, depending on the fault and the parts. Because we plan from pictures or a survey, a job in Harold Wood can usually be finished in one visit.
- Tell us the make, the symptoms and any error code, and send a photo of the display if you can.
- We diagnose on site, checking the codes, electrics, airflow, drain and refrigerant pressures.
- You get a plain explanation of the fault and a fixed price for putting it right.
- We repair the fault, and where refrigerant is involved, the leak is found and fixed before recharging.
- Before leaving, we run it through its modes and write up what was found and done.
Getting ready for the visit
- Let us know where the consumer unit is
- Let us know if the building has a permit or sign-in process
- Have the make and model of any existing unit to hand
How to get a quote
Here’s what helps us quote: where the property is and what kind of building it is, pictures of the rooms or units, the brand and model of anything already fitted and any symptoms, from error codes to drips. Then phone us on 07833 053749 or write to us at info@aircondoctor.co.uk.
Advice
For landlords and property managers
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We can quote either party and send the records to whoever needs them.
Bigger systems bring extra duties: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We can arrange it, prepare the system for it and fix what it finds.

What happens if it’s left?
If your air conditioning in Harold Wood has developed a fault, it’s worth booking a diagnosis now. It takes an hour or two to diagnose most faults, with the repair time depending on what we find, and the repair is priced before anything else happens, and our emergency line runs 24/7. A system that is left with a fault, or without a service, typically costs more to run.
Putting the work off seldom saves money. Faults and wear in a system tend to grow, and a system working harder than it should costs more to run. If you are unsure, call us on 07833 053749, or email if that’s easier and we will give you an honest view and a fixed price.
