What We Cover

We install, maintain and repair heating, ventilation and air conditioning systems for businesses across Surrey, London and the Home Counties.

Commercial Air Conditioning Installation

Whether you're fitting out a new space or replacing a system that's past its best, we design and install HVAC systems that suit your building, your usage, and your budget. No off-the-shelf solutions - everything is spec'd to what you need.

Commercial HVAC Maintenance

Regular servicing is the most cost-effective thing you can do for your HVAC system. It keeps efficiency up, catches problems early, and extends the life of your equipment. We recommend quarterly servicing for commercial premises.

HVAC Emergency Repairs

When something breaks down, we get it sorted. Our engineers carry common spare parts on the van, so most jobs are fixed the first time. For emergencies, we aim to be with you within two hours.

HVAC System Upgrades and Energy Efficiency

Older systems cost more to run and break down more often. If yours is getting on, upgrading to a modern, energy-efficient system can cut your bills and reduce the chance of unexpected failures.

A. F-Gas certification is a legal requirement for any engineer working on commercial air conditioning, heat pumps, or refrigeration systems containing fluorinated gases. Without it, an engineer can't legally install, service, or decommission these systems. F-Gas regulations also require regular leak checks and record-keeping, which is part of the audit trail your building needs for compliance. All our HVAC engineers are F-Gas certified, so the work is legal, documented, and properly recorded.
