What owners can safely do
On air conditioning, the filters in the indoor unit are normally the one part owners can clean 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.
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.
What affects the cost of air conditioning repair
Some jobs are bigger than they look, and some smaller. The main factors:
- What state the existing equipment is in
- One-off work versus a regular service cycle
- The size of the job
One room or a whole building, the quote is built the same way: the work involved, the access and the equipment. You will have a fixed price before work begins, and the quote sets out the VAT.
Asking for a quote
When you call or email, these details help:
- The rating plate or label on any existing unit
- Where the outdoor unit is, or where you’d like it
- A photo of the consumer unit with the cover closed
Every quote starts with a look at the job, from a site survey or, where the job is straightforward, from photos and measurements. After that, we send a fixed price before any work starts.
Barnehurst: your questions answered
What’s the best way to get a price for air conditioning repair in Barnehurst?
The easiest way is to ring 07833 053749 or write to us at info@aircondoctor.co.uk with a few details and pictures. We reply the same working day, and the quote is fixed before any work starts.
Is there an emergency air con repair line for Barnehurst?
The emergency line is open around the clock, and Barnehurst is one of the places it covers. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
Do you look at the job first?
Yes. Photos often do the job for simple work, while larger systems and faults that need testing are seen on site.
What accreditations do you have?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Why isn’t my air con cooling?
Common causes are a blocked filter, the wrong mode or set temperature, an outdoor unit that can’t breathe, a failed sensor or board, or low refrigerant from a leak. Check the filter and the settings first, and if that does not fix it, ring us on 07833 053749 or drop us a line.
Whose job is it to check the system for leaks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Which manufacturers do you install and repair?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.

The process
Each visit runs to the same pattern: check the plan with you, put the dust sheets down, carry out the job, test what we have done and talk you through it.

- We start with what the unit is doing, the make and any code.
- The engineer diagnoses the fault on site, testing rather than guessing.
- We explain the cause in plain English and give you a fixed price.
- Once agreed, the repair goes ahead.
- We test the system in operation and leave you a note of the fault and the fix.
Preparing for the visit
- Tell us about parking and loading

When it’s something else
We will always give you a straight diagnosis, so here’s what this work cannot put right:
- A building problem rather than a system fault
- A refrigerant fault on an R22 system (new R22 can’t be used for servicing, so replacement is typically the answer)
- A unit that was never big enough for the room
If in doubt, ring us on 07833 053749 or use the quote form and we’ll say what we think before you book.
