AHU & aIR CONDITIONING REFURBISHMENT · Nationwide
RESTORED PERFORMANCE.
FRACTION OF THE COST.
From ageing air handling units to tired commercial AC systems, we refurbish any brand – restoring efficiency and compliance far faster than a full replacement, at 40–60% of the cost of a new install.

WHY REFURBISH
WHAT SETS REFURBISHMENT APART
Once a system passes the decade mark, efficiency losses creep in – even if nothing has visibly gone wrong yet. Refurbishing an AHU is a practical, budget-friendly way to bring performance back up to spec and get ageing plant back in line with today’s HVAC compliance requirements, without the cost or upheaval of ripping it out and starting again.
IS IT TIME?
Signs your system is due a refurbishment
- It’s over 10–15 years old, even if well maintained
- Energy bills are creeping up year on year
- More frequent breakdowns or reactive callouts
- Excessive noise or vibration from fans or motors
- Visible corrosion or water ingress at the unit
- Temperature or airflow complaints from occupants
- Spare parts are becoming hard to source
- Struggling to pass F-Gas leak checks or insurance/compliance inspections
our process
HOW A REFURBISHMENT WORKS
1
Survey & Report
An engineer inspects the unit and provides a written condition report and recommended scope.
Comprehensive survey, no obligation
Written condition report on fans, coils, controls & casework
Clear refurbish-vs-replace recommendation
2
Fixed Quotation
A clear, itemised quote covering scope, programme and any access or shutdown requirements.
Itemised, fixed-price quote
Scope agreed & signed off before work
Programme built around your access and shutdown needs
3
Refurbishment Works
Carried out on-site or off-site, staged where needed to minimise downtime for live environments.
F-Gas certified installation
Staged delivery to minimise downtime
Suitable for live, 24/7 or occupied environments
4
Commission & Handover
Full recommissioning, F-Gas paperwork and technical documentation, with optional aftercare.
Full recommissioning and performance testing
F-Gas paperwork and compliance documentation provided
Optional ongoing maintenance cover available
SCOPE OF WORKS
WHAT WE REFURBISH
Every project is scoped individually following survey – from a single component upgrade to a complete strip-and-rebuild.

FANS, MOTORS & DRIVES
Upgrade to energy-efficient EC fans for lower running costs and easier maintenance

COILS, FILTERS & DAMPERS
Clean, repair or replace coils and filtration to restore airflow and air quality

CASEWORK, CONTROLS & REFRIGERANT
Corrosion treatment, BMS upgrades and F-Gas compliant refrigerant handling
FAN TECHNOLOGY
Why EC fans make the difference
Fan and motor upgrades are usually where a refurbishment delivers the biggest efficiency gain. Replacing old belt-driven or AC induction fans with EC (electronically commutated) fans is one of the highest-impact changes we make to an ageing AHU.
- Significantly lower energy use, especially at partial load – where most AHUs run most of the time
- Built-in speed control, with no separate inverter or belt-drive to maintain
- Quieter running, noticeable in occupied spaces
- Fewer moving parts than belt-driven fans, so less routine maintenance
- Multi-fan arrays keep ventilation running even if a single fan fails
- Straightforward integration with modern BMS and demand-based controls
SUSTAINABILITY
A GREENER ALTERNATIVE TO REPLACEMENT
Refurbishment is becoming increasingly popular as companies want to hit their net zero targets. It isn’t just the cheaper option – it’s one of the simplest ways to cut a building’s environmental footprint. Extending the working life of existing plant avoids the embodied carbon, raw materials and waste involved in manufacturing a brand new unit.
Lower Embodied Carbon
Adding 15-20 years to an AHU’s working life avoids the manufacturing, raw material and transport footprint of building a replacement unit from scratch.
Less Waste to Landfill
Only worn components are stripped out and responsibly recycled – the casework, structure and ductwork already in the building stay exactly where they are.
Lower Running Emissions
EC fan and controls upgrades can cut a system’s energy use by up to 40%, reducing its ongoing carbon footprint for the rest of its extended life.
