Air conditioning repair for homes and businesses in Green Street
We treat a faulty system the way a doctor treats a patient: diagnose the cause, treat it properly and sign it off when it’s working. Guesswork costs money, and replacing a board when the fault is a sensor leaves the problem in place. If you are dealing with a unit that barely blows any air and a unit that has lost refrigerant, we can help.
A visit to Green Street is planned so we can typically finish in one go, though some parts have to be ordered from the manufacturer.
Aftercare is simple, and most of it is in the manual: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. That also helps where the warranty terms ask for regular servicing.

The process
You do not need to do much on the day. Just let us in and point us to the units, or to where they’ll be fitted, and we take it from there. At the end, we tidy up and run through the work with you. Pictures of the space and where the outdoor unit could go let us plan the work in Green Street.
- Diagnose: test the system until the cause is clear.
- Prescribe: tell you the cause and the fixed cost of the cure.
- If the repair isn’t worth doing, we say so and explain the options.
- Treat: carry out the repair, sealing any leak before refrigerant goes back in.
- Finally, a check that it’s working and a record of what we did.
Preparing for the visit
- Arrange for someone to be there to let us in
- Let us know where the consumer unit is
- Tell us about any building rules, permits or sign-in

Common questions in Green Street
Is there an emergency air con repair line for Green Street?
Yes: ring the emergency line, day or night, from anywhere in Green Street. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
Can you do air conditioning repair in Green Street?
Yes, Green Street is within the area we cover. Just phone 07833 053749 or fill in the contact form with a few details.
Which manufacturers do you install and repair?
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.
Why is there ice on my air conditioning pipes?
The coil gets too cold when air can’t move across it or when the refrigerant charge is low. A dirty filter is worth checking first, and if it’s clean, the system needs a diagnosis.
Does servicing affect my warranty?
Check the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Keep every service record either way.
Why is my air conditioning leaking water?
Most of the time, it’s the condensate system: a blockage, a kink or a pump that has stopped. Switch the unit off to avoid water damage, then call us.
Who is responsible for leak checks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
When it’s something else
We’ll always give you a straight diagnosis, so here’s what air conditioning repair won’t do:
- A leak on an old R22 system
- No power to the building at all
- A unit that was never big enough for the room
If you’re not sure, just give us a ring on 07833 053749 or send an email and we’ll give you a straight answer before booking.
Where we work
- Ceiling cassettes
- Multi-split systems
- VRF systems
- Heat pumps
- Wall-mounted split systems
- Ducted systems
Rented and managed buildings
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is, and we can work for either side.
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed-price quote.
Why deal with it now?
For a faulty system in Green Street, an early diagnosis is the sensible first step. The visit takes as long as the fault needs, from a quick fix to a return visit for parts, and you get a fixed price for the repair before any work goes ahead, with a 24/7 line for emergencies. An early booking makes the visit to Green Street easier to arrange.
A single unit or a whole estate, we price it on the same basis: the work involved, the access and the equipment. You will have a fixed price before any work starts, with VAT shown clearly.
