Air conditioning repair in Harefield, done properly

Ring 07833 053749 with the make, what’s happening and any code, and we will agree the next steps. The work covers multi-split systems, ducted systems and ceiling cassettes, and the jobs we see most are a flashing light and a system that won’t run and water dripping from the indoor unit.
Around Harefield, most of our repairs are in homes, with some small businesses. What you tell us about the fault shapes the visit, so a description and a photo of any error code really help.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Safe owner checks
Owner care supports servicing; it does not replace it. Simple care keeps the air moving through the system, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.
The process
Our engineers arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and anything electrical is made safe before work starts. The work itself takes anything from an hour or so to a full day, depending on the fault and the parts. We plan the visit to Harefield from the survey or your photos.
- We start with what the unit is doing, the make and any code.
- On the diagnosis visit, we test the electrics, airflow, drain and refrigerant.
- The fault is explained simply and the repair priced up front.
- Once agreed, the repair goes ahead.
- The system is run and checked, and you get a written note of the repair.
How to prepare
- Plan for pets to be kept clear during the visit
- Make sure we can reach the outdoor unit, or where it will go
- Mention any roof access, ladders or high-level work

FAQs for Harefield
Is there an emergency air con repair line for Harefield?
The emergency line is open around the clock, and Harefield is one of the places it covers. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
Is Harefield within the area you cover?
Yes, and the size of the place makes no difference to how we work. A few photos and the postcode are enough to get things started.
Do I get paperwork after the visit?
Yes. Each visit is written up, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is written up, with F-Gas records where refrigerant work is involved.
How long does the work take?
Your quote will say how long we expect to be there. In most cases, it takes an hour or two to diagnose most faults, with the repair time depending on what we find.
How much does an air conditioning repair cost?
A diagnosis call-out is from £75 + VAT. When we have found the fault, the repair is priced before we do it. The final cost depends on the fault, the parts and the access.
What can I do with an old R22 system?
Servicing with new R22 isn’t allowed, because it depletes the ozone layer. Some non-refrigerant faults can be repaired if parts are available, but a refrigerant leak usually means replacement. We explain the options and quote for a new system if that is the answer.
What air conditioning won’t do
To be straight with you, some problems need a different answer:
- An R22 system that has lost its refrigerant
- A discontinued model with no parts available
- Heat gains the system was never designed for
If in doubt, phone 07833 053749 or use the quote form and we will say what we think before booking.
Where we work
- Ceiling cassettes
- Wall-mounted split systems
- Ducted systems

Aftercare tips
Aftercare is straightforward, and it helps at the next service:
- Book an annual service after the repair
- Leave a tripping breaker off and call us
- Leave space around the outdoor unit
You get a note of the fault and what we did: what was wrong, what was replaced and any refrigerant work. Any refrigerant work is recorded in the F-Gas records, so keep the note with the system’s paperwork.
Sensible use helps. Moderate settings and a closed room mean less strain and the system does not have to work as hard.
