Common problems we fix in North Lee
Small refrigerant leaks don’t announce themselves. The system just cools or heats a little less well each year, until it can’t keep up on the hottest or coldest days.
What we are most often called about:
- Systems that need a 6 or 12-monthly leak check
- A system that struggles to cool on warm days
- Systems that haven’t been serviced for a while
Spring is a good time for a service, before the system is needed for cooling.
What your quote should include
- The make and model of any parts or equipment being quoted
- How extra work would be agreed if they find something unexpected
- Whether they hold F-Gas company certification, not just individual qualifications
Air conditioning servicing in North Lee
Servicing covers both halves of the system: the indoor units in the rooms and the outdoor unit outside. Filters and coils are cleaned, the drain is cleared, and the electrics, controls and refrigerant performance are all checked. We carry out air conditioning servicing for homes and businesses in North Lee and the rest of Buckinghamshire, whatever the make. If the problem is error codes or flashing lights on the indoor unit and F-gas leak checks falling due, we can help.
For a home in or near North Lee, a service once a year suits most systems, ideally in spring before the warm weather.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We will tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

What air conditioning servicing can’t fix
In fairness, some problems need a different answer:
- A failed compressor, fan motor or circuit board, which needs a repair
- A refrigerant leak, which needs finding and repairing, not topping up
- A system that’s too small for the room it serves
If in doubt, ring us on 07833 053749 or send an email and we’ll say what we think before booking.

What we do, step by step
Think of the visit in three stages: look, put right and sign off. First we check the system or the space against the plan, then we do the work, and finally we test, record and explain. The middle part takes longest, and that takes anything from an hour for a simple split system to most of a day for a larger installation. For a place like North Lee, the timing is set with you and the travel is our side of the planning.
- It begins with a few questions about the make, the rooms served and any symptoms.
- Each indoor unit has its covers lifted so the filters, coil and tray can be cleaned.
- Outside, the coil is cleaned, the fan checked and the area cleared.
- We test the electrics, the controls and how the refrigerant circuit is performing.
- Anything we find is explained, with a fixed price if it needs a repair.
Preparing for the visit
- Let us know if the units are on a roof, a high wall or in a locked area
- Have the make and model of any existing unit to hand
- Let us know if the building has a permit or sign-in process

Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your pictures and details. Then you get a fixed price before any work starts.

Why act early in North Lee
A service can find a worn part or a loose connection while the system is still running. Left alone, the same fault tends to show itself when you most need the system. Small faults tend to grow, so it’s worth dealing with them early.
Typical ranges are on our prices page, but each job is priced on what it involves. Call for a fixed-price quote, and we’ll explain what it covers.

North Lee questions
Do you cover North Lee for air conditioning servicing?
Yes. North Lee is one of the places we cover. To start, give us a ring on 07833 053749 or fill in the contact form with a few photos.
Does my air con in North Lee need a yearly service?
A yearly visit is right for most households. Larger systems holding 5 tonnes CO2 equivalent or more also need a leak check at least every 12 months under the F-gas rules.
Do you provide F-Gas records?
Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.
What does F-Gas certified mean?
The law says any company working on equipment containing F gas has to be certified, and each engineer needs the right qualifications too. It means the refrigerant in your system is handled legally.
Do I need a service to keep the manufacturer’s warranty?
Each manufacturer sets its own terms. Some may have servicing conditions attached, so check the terms for your system. We can explain the terms, and each visit is recorded.
Do you offer emergency call-outs?
Yes. There’s a 24/7 emergency line for problems that cannot wait for a planned visit. Call 07833 053749 and tell us what’s happened.
Is a regas part of an air conditioning service?
We check refrigerant performance on every service, but adding gas is separate work. If gas has been lost, the right step is a leak search and repair, then a regas with a fixed price for each step.
