NVK Air, heating and cooling

Aftercare

For systems we fitted.

If a system NVK Air installed is not working as it should, this is what to do. We fit new systems; we do not sell servicing or care plans.

Heating and cooling installed across London. Based in Harrow and Stanmore.

Your warranty.

Every install has our 12 month parts and labour warranty, on top of the manufacturer’s warranty on the unit, which we register for you at handover. If something we fitted is not right, call 020 3822 0118 and we come back.

Manufacturer warranties generally set out a servicing interval and expect it to have been kept to, so read the terms in your handover pack. Our full terms are on the terms page.

Anything that involves the refrigerant circuit has to be done by a certificated engineer working for a registered company. At NVK Air that is an F-Gas Category 1 qualified engineer, and NVK Air is a REFCOM certified company, number REF1025662.

What the symptom usually means.

Describing the fault on the phone often saves a visit. None of this is a diagnosis without seeing the unit, but it will tell you what to mention when you call.

It runs but the room stays warm

Often a dirty filter or a fouled indoor coil choking the airflow. The manufacturer's manual in your handover pack shows how to clean the filters.

Water dripping from the indoor unit

Nearly always the condensate drain rather than the refrigerant circuit. Turn it off and call, because water and electrics in the same box is the one symptom worth acting on quickly.

Ice on the pipework

A sign that something upstream is wrong, usually airflow or the refrigerant charge. Running it iced up can damage the compressor, so switch it off rather than persevering.

A smell when it starts

Damp sitting on the coil and in the drain pan. It is a cleaning job rather than a repair.

Louder than it used to be

Outdoors, usually debris in the fan or a mounting that has worked loose. Indoors, usually a blower wheel with a season of dust on it.

An error code on the remote

The codes are manufacturer specific and narrow the search a long way. Read it out on the phone and we can often tell you whether it needs a visit or a reset.
