Air con repairs in Lower Horncroft
For air conditioning repair in Lower Horncroft, one call is all it takes, from the first look to sign-off. F-Gas certified, NICEIC approved and Checkatrade members.
- A flashing light and a system that will not run
- Water leaking from the unit or through the ceiling
- A unit that will not start
When something else is needed
In fairness, there are a few things this work won’t fix:
- A refrigerant fault on an R22 system (new R22 cannot be used for servicing, so replacement is normally the answer)
- Cooling that falls short because the system is too small
- A room that overheats because of the building, such as a lack of shading or ventilation (the system may need help, not a repair)
Not sure which it is? You can call 07833 053749 or use the quote form and we’ll tell you honestly.

Before you call an engineer
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It makes our diagnosis quicker, and a photo or a short video of the display is even better.

What happens if it’s left?
A struggling system costs more to run. Poor airflow or low refrigerant means more running time for less effect and the extra work wears the parts faster. Booking before summer means the work in Lower Horncroft is done before the hot weather.
Several rooms, units or sites on one quote can make for a more efficient booking. Mention every unit or room you need covered and we will price it together.
