AHU Maintenance · All of Cumbria
Air handling unit maintenance in Cumbria
Air handling units kept clean, balanced and filtered — the difference between fresh air and a warm smell in a busy building.
Our Services
What we do
Filter changes, belt and bearing checks, coil cleaning, drainage, damper and actuator checks, and airflow verification so the unit is actually delivering what it was designed to.
Why it gets neglected
AHUs are usually on a roof or in a plant room and nobody sees them until the building smells or the humidity climbs. By then the filters are usually long gone.
Who we look after
The businesses we keep running
Commercial cooling covers a lot of ground. If your trade depends on stock staying at temperature, or on customers being comfortable, it is work we do every week.

- Restaurants and gastropubs
- Cafés, delis and coffee shops
Food & Drink
- Butchers, bakers and fishmongers
- Farm shops and food producers
- Breweries and bottle shops
Retail

Different businesses. Different cooling demands.
Every one of those has different demands. A village shop needs a display cabinet that holds temperature through a hot Bank Holiday with the door opening every thirty seconds. A care home kitchen has to evidence food safety records. A pub cellar has to hold eleven to thirteen degrees through a Saturday night with the hatch open. We size, install and maintain for the job in front of us rather than fitting whatever is on the shelf.
Planned maintenance
Planned preventative
maintenance
Our maintenance agreements include planned visits through the year, agreed to suit your equipment. Each visit includes:
Inspect equipment condition and operation
Check refrigerant pressures and temperatures
Inspect for visible refrigerant leaks
Clean accessible condenser and evaporator coils
Check compressors, fans and motors
Inspect electrical terminals and controls
Check filters, condensate trays and drains
Verify thermostat/controller operation
Record electrical and operating readings
Issue a written service report with recommendations
Cabinet or cold room running warmer than its set point
Ice building up on the evaporator or around the door
The unit runs constantly and never cycles off
Unusual noise from the condensing unit
Water pooling underneath or inside the cabinet
Electricity bills climbing with no change in trade
The system trips the breaker or keeps resetting
Cellar cooling not holding its set temperature
When to call
Signs your equipment needs attention
Most breakdowns give warning first. Catching any of these early is almost always cheaper than an emergency call-out and a skip full of stock.
If you have noticed any of these, ring us before it fails properly. A refrigerant leak found on a service visit is a straightforward repair; the same leak found on a Friday night is a lost weekend of trading, a claim on your stock, and a food safety problem you have to evidence afterwards.
Planned work
Booked around your trading hours
We schedule servicing for when you are quiet, not when you are busy. Early mornings before a kitchen opens, weekday afternoons for a pub, or a full shutdown week for a bigger site.

Cumbria-wide
Wherever you are in the county
Our engineers are out across Cumbria every day — Carlisle and the north, the west coast, Furness and the south, and the whole of the Lake District in between.
Where we work
AHU maintenance across Cumbria
North Cumbria and the Eden Valley
Carlisle, Penrith, Brampton, Wigton, Appleby-in-Westmorland and Kirkby Stephen are covered on a northern round. Most of the work up here is commercial refrigeration for the city's convenience stores, restaurants and care homes, along with cellar cooling for the pubs and hotels, and air conditioning for offices and salons.
The Lakes and the south
Kendal, Windermere, Ambleside, Keswick, Coniston, Kirkby Lonsdale, Sedbergh and Grange-over-Sands are tourist towns where kitchens and cellars work hardest in season. We fit and service VRF and multi-split systems for hotels, keep display cabinets running for delis and farm shops, and handle breakdowns and call-outs through the summer.
The west coast
Whitehaven, Workington, Cockermouth, Maryport, Egremont, Cleator Moor, Silloth and Seascale sit on the coastal run. Salt air is hard on condensers, so this is where planned servicing earns its keep, and where a lot of our cold room repair and installation work comes from.
Furness and the far west
Barrow-in-Furness, Ulverston, Dalton-in-Furness, Millom, Haverigg, Bootle and Broughton-in-Furness are on our doorstep — we are based at Steel Green in Haverigg. We cover everything from heat pump servicing to air handling unit maintenance. If you are unsure whether you are in range, ring us: we cover the whole of Cumbria.

FAQs
Frequently asked questions
Typically quarterly for filters in a busy building, with a fuller service annually. Kitchens and gyms need more.
Airflow drops, the fan works harder, running costs climb and air quality falls. Eventually coils clog and the cost rises sharply.
Often yes, and frequently without new plant — correct filtration, clean coils and properly set dampers make a large difference.
We keep common sizes and can source the rest quickly. Sizes are recorded so repeat visits are straightforward.
Yes. We will survey it first and report on its condition.
