How we handle air conditioning repair in Hunsdonbury
We treat a faulty system the way a doctor treats a patient: find the cause, put it right and check it’s healthy before we leave. Guesswork costs money, and topping up refrigerant on a system with a blocked filter fixes nothing. If the problem is drips from the indoor unit and air conditioning running but not cooling, we can help.
Around Hunsdonbury, repairs tend to be home systems, garden rooms and a few businesses. A photo of the unit’s label and a description of the fault help us plan.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. Keep it with the system’s paperwork, because it helps with any later warranty question.

Why is my air conditioning showing a fault code?
Each manufacturer uses its own codes, and one code can have more than one cause. Send us a photo of the display with the make and model, and we will diagnose the fault on site.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Why is my air conditioning blowing warm air?
There are several possible causes, from simple to serious. Diagnosis confirms the cause and you get a fixed price before the repair.
Why use an F-Gas certified company?
Companies working on equipment that contains F gas must be certified by an approved body, and each engineer needs the right qualifications too. It means the refrigerant in your system is handled legally.

What the work involves, system by system
Fans and compressors
Fan motors and bearings wear over time, and the first sign is often noise or weak airflow. Indoor and outdoor fan motors can normally be replaced where the parts are available.
VRF systems
In a VRF system, many indoor units share outdoor plant. We use the system’s fault history and codes, then test to confirm, and repairs are priced before they go ahead.

Safe owner checks
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
On air conditioning, the filters in the indoor unit are typically the one part owners can clean where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
