Sometimes you come across a “temporary repair” that should never have happened… and then there’s this beautiful little quick fix. 😳

A dustpan Sellotaped to a leaking air conditioning unit, directing the water into a bucket above a 415V electrical panel. 🤦‍♂️

We weren’t even there for this—it was something we spotted while attending another callout.

But apparently, “it’s fine”… 😳

We’re focusing on building our regional work across South Wales and into the South West, particularly within around two hours of Cardiff.

If you look after refrigeration or air conditioning for your business, or arrange maintenance across several sites, we’d love to have a chat.

We carry out servicing, repairs and installations, with a 24/7 breakdown service for when things go wrong.

We’re keen to build long-term relationships with businesses needing regular maintenance, as well as facilities management companies looking for a dependable team to support their sites.

Perhaps your current contract is coming up for renewal, you’ve got a project planned, or you need some extra support — feel free to get in touch.

If someone in your network might be worth us speaking to, an introduction or a share would mean a lot.
