🌬️ Do you have a cold conservatory, garden room, or attic room that’s unusable in the winter (and boiling in summer)?

Instead of installing traditional radiators or extending your central heating, have you considered a heat pump (also known as air conditioning)?

✅ Heats and cools — perfect all year round
✅ Ideal for spaces where traditional heating would be costly or disruptive
✅ VAT exempt for residential installs
✅ Quieter, energy-efficient, and not as expensive as you might think

📞 Get in touch for a free, no-obligation quote — and turn your cold room into a comfortable living space all year round.

💧 A smart solution for a tricky problem!

Today our engineers installed bespoke drip trays to manage water ingress from properties above.

When leaks or condensation occur from upper floors, it can be hard to stop the source — so we provided a practical solution from below, helping our client protect their premises and equipment from further damage.

✅ Custom trays designed and installed on-site
✅ Preventing ceiling damage and disruption
✅ Offering peace of mind where the cause can’t be controlled

At Call Jim, we’re all about finding real-world solutions to complex building challenges — delivering reliable mechanical and HVAC support tailored to each client.

🔧 Job complete at Isqueezeuk!

Yesterday our team tackled two key issues to keep their systems protected and running efficiently:

1️⃣ Wall Protection in the Chiller
We installed tough steel angle to stop pallet damage. A small upgrade that makes a big difference to long-term performance!

2️⃣ Freezer Coil Replacement
We replaced the faulty coil with a new, sealed and braced unit, tested the system, and recharged it with fresh refrigerant—getting it back to full working order.
