Air conditioning repair in Lee: the local picture
The middle of Lee is part of the Lee Manor Conservation Area. Draw a one-mile circle round the middle of Lee and it takes in 3 conservation areas. On the National Heritage List, around 16 entries fall within 0.5 miles of the middle of Lee; Lee Public Library (grade II*) is one. Should a unit ever need replacing on a listed building or in a conservation area, ask us about consent first. The Valuation Office Agency’s council tax figures put about 49% of homes across Lee and its surrounding area before 1919, and the 2021 Census found about 57% of households live in flats. If you live in a flat, mention any roof hatch, balcony or managing agent we will need to get to the outdoor unit. In London, access to outdoor units on roofs and balconies can need planning, so tell us how to reach yours.
For a school like Brindishe Lee School, urgent repairs can be booked straight away and bigger work in the holidays. If your system near Lee station stops in a hot spell, our 24/7 line is open.

Air conditioning repair in Lee, done properly
A sealed system shouldn’t lose refrigerant, so a low charge means a leak somewhere. Simply adding gas means it will leak away again. We locate the leak, repair it, test, evacuate and recharge and write it up in the F-Gas records. If you’re dealing with a suspected refrigerant leak and weak airflow from the indoor unit, we can sort it out.
London systems in Lee often run long hours in summer, which is when weak cooling, leaks and error codes tend to appear. A photo of the error code and the unit’s label helps us arrive with the right parts in mind.
Think of the paperwork as the system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

Let and managed properties
Larger air conditioning systems in buildings need more than servicing: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. Where a building is let or managed, the lease or contract should make clear who looks after the system, and we can work for either side.
What air conditioning will not do
In fairness, some problems need a different answer:
- A unit whose parts are no longer made (replacement may be the only option)
- A power cut or a fault on the incoming supply to the building (that is for the network operator)
- Cooling that falls short because the system is too small
If you’re not sure, just give us a ring on 07833 053749, or email if that’s easier and we will give you a straight answer.
What the work covers
- Heat pumps
- VRF systems
- Multi-split systems
- Wall-mounted split systems
- Ceiling cassettes
- Ducted systems
The process
Protection comes first: dust sheets over floors and furniture near the work and nothing is moved without asking you. Then the electrics are made safe and the work begins. The work on site takes an hour or two to diagnose most faults, with the repair time depending on what we find, and we clear up before we go. For a job in Lee, tell us about parking, permits and access to the building when you get in touch.
- First, a few questions by phone or email about the brand, the fault and anything shown on the controller.
- At the property, readings and tests narrow the problem down to its cause.
- Nothing is repaired until you’ve heard what’s wrong and agreed a fixed price.
- The fix goes in, with any refrigerant work tested and written into the F-Gas records.
- We run the system, check it’s working properly and note anything else that needs attention.
Preparing for the visit
- Clear a path to the units and the space around them
- Clear access to the fuse board
- Keep pets and children away from the work area

What the work involves, system by system
Refrigerant leaks
Adding refrigerant without a repair is not a fix, and it releases more refrigerant into the air. We always find and fix the leak first.
Multi-split systems
On a multi-split, one outdoor unit serves several indoor units, so a fault outside can affect every room, while a fault inside may affect only one. It tells us where to look first.
Questions from Lee
Is Lee in your area for air conditioning repair?
Yes. Lee is one of the places we cover. Get in touch with the details and we reply the same working day.
Can I get a fixed-price quote for air conditioning repair in Lee?
Use the quote form, or email, with a description of the job. Simple jobs can be priced from photos; otherwise we arrange a site survey and then give you a fixed-price quote.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need, and the quote is based on that.
What does the error code on my air conditioning mean?
The code is the system’s own clue to the fault, but testing confirms the cause. Write down the code and turn the unit off if it has stopped, and phone us on 07833 053749, or email if that’s easier.
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. 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 can tell you which band your system falls into.
Can you look at a system you didn’t fit?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.
Do you offer an emergency repair service?
Yes, 24/7. Urgent cases include water leaking through a ceiling or a server or comms room overheating and we’ll tell you what to do first. Call 07833 053749.
