About KT Air

The counter behind the installer


KT Air is a trade counter for ventilation, air conditioning and heating equipment, serving installers, contractors and facilities teams from our branch in Pevensey, East Sussex.

We hold the everyday items on the shelf, from spiral duct and fittings to flexible hose, axial and inline fans, brackets and fixings. We also stock the bigger-ticket kit: split systems, air source heat pumps, dehumidifiers and commercial heaters. If it moves, cleans, heats or cools the air in a building, the chances are it is already in the building.

Our customers work to deadlines, so the whole business is built around getting the right part into your hands quickly. Order online and we will pick it and ring you the moment it is ready, usually the same day. The people answering the phone are engineers rather than order-takers, so if you are sizing a system or trying to match an obsolete part, it is worth calling them.

    Sizing a system, matching an obsolete part or checking a spec. Talk to someone who knows.

Customer feedback

What the trade says


  • I put the order through on my phone from the last job and it was boxed up on the counter by the time I got there. Beats standing about waiting for someone to go and look for it.
    Dave WhitfieldContracts Manager
  • Needed six inline fans and a run of insulated flex at short notice for a hotel job. Ordered at half four, got the call first thing and had them fitted by the afternoon.
    Sarah EllisonDirector
  • The technical team actually know the products. They talked me through sizing a heat pump for an awkward retail unit rather than just quoting me the biggest one on the shelf.
    Michael GrantSenior Engineer
  • Being able to pop in for a single bracket makes a real difference to a small firm like ours. No minimum order and no funny looks for spending a tenner.
    Priya SharmaOwner
  • Straightforward account, clear prices on screen once you log in, and they always ring when the order is ready. It sounds basic but plenty of places still get it wrong.
