- A unit showing a fault code
- Humming, rattling or squealing from the system
- Water dripping from the indoor unit
How it works
Protection comes first: sheets over the floor and any furniture nearby, and we ask before moving anything. After that, anything electrical is made safe and we start. It takes a short visit for one split system, longer for multi-split, ducted or commercial plant, and we tidy up before we leave. A few pictures help us make the most of a visit to Langley.
- First, we agree a time and confirm the cost of the service.
- Before any cleaning, the system is run so we can see how it behaves.
- Then the cleaning: filters, coils, fan and the drain line.
- The electrics, controls and refrigerant performance are checked, with a leak check where required.
- A final test run follows, then you get the service record.
Before we arrive
- Make sure someone can let us in at the agreed time
- Keep pets and children away from the work area
- Mention any managing agent or landlord rules we need to follow

Air conditioning servicing in Langley, done properly
Servicing does not mean topping up refrigerant. Refrigerant runs in a sealed circuit and shouldn’t need adding to. Where the checks suggest gas has been lost, the right step is to find the leak, and we’ll set out how. If you are dealing with a service that’s overdue and systems that need a 6 or 12-monthly leak check, we can help.
In a village like Langley, outdoor units often face hedges, fields or gardens, so leaves, seeds and cobwebs collect on the coil. A yearly service clears them.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler, so keep it safe.

Looking after it afterwards
How well a system lasts depends on use and care. We suggest:
- Keep the drain outlet clear
- Hold on to every service report
- Keep the filters clean between visits
When we finish, we leave a record of the visit, listing the work, the checks and any recommendations. Keep it with the manufacturer’s paperwork so you have the whole history together.
Make sure condensate pipes outside are not crushed, blocked or buried. A pipe that is been knocked or covered can back up into the indoor unit.
Langley questions
Does my air con in Langley need a yearly service?
Once a year suits most home systems. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.
Do you cover Langley for air conditioning servicing?
We do: Langley falls inside our working area. Get in touch with the details and we reply the same working day.
Do you have a 24/7 line?
Yes, 24/7. When you call, tell us the make, what’s happening and any error code, and we will talk you through the next steps.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Langley and across Hertfordshire. Tell us who should receive the paperwork.
Do you work on all makes?
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’ll take it from there.
Do you do service contracts for air con?
We do. A contract sets out how often we visit and what each visit covers with the price fixed when you accept the quote. It suits anyone who would rather not track service dates.
Whose job is it to check the system for leaks?
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.
What air conditioning won’t do
A few issues sit outside what this work can do:
- Installation faults that need reworking
- Lost refrigerant, where the fix is a leak repair
- Heat gains the system was never sized for
If in doubt, phone us on 07833 053749 or email us and we will say what we think before you book.
Parts of the system we cover
- Ceiling cassettes

Air conditioning servicing in Langley: the local picture
About 40% of households live in terraced houses, according to the 2021 Census. On terraced streets, outdoor units are normally at the back, so tell us how we get to the rear of the property. Historic England lists about 14 buildings and structures within half a mile of the centre of Langley, including Dyes Farmhouse (grade II*). We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that.
A service once a year suits most home systems, and some business systems need more. Schools such as The Thomas Alleyne School can book servicing for half term or the summer break, when rooms are empty.

How we price air conditioning servicing
We quote each job individually. These are the things that affect it:
- What kind of system it is
- How many units are involved
- The brand, model and parts involved
Putting the work off seldom saves money. Small problems, from blocked filters to slow leaks, tend to get worse, and a system working harder than it should costs more to run. If you are unsure, ring us on 07833 053749 or drop us a line and we will give you an honest view and a fixed price.
What to send for a quote
Before you ask for a quote, gather:
- Wide pictures of the room or the existing unit
- A short video of any fault, such as a noise or a flashing light
- The rating plate or label on any existing unit
Quotes do not take long. Call or email with a few details and we will come back to you the same working day. If we need to see the property first, we book a survey at a time that works for you.
From one of our customers
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
