Air conditioning & refrigeration guides.

Air Conditioning Not Cooling Properly

A unit that runs but never quite cools the room is one of the most common calls we get, and the cause is rarely the compressor.

Air Conditioning Blowing Warm Air

Warm air from a unit that should be cooling usually means either a settings mix-up or a refrigerant fault, and telling the two apart matters.

Air Con Leaking Water Indoors

Water appearing under or around an indoor unit is almost always a drainage problem rather than a refrigerant one, and it's often an easy fix.

Air Conditioning Smells Musty

A sour, damp smell when the AC kicks in is almost always biological growth on the indoor coil, not a fault with the refrigeration circuit itself.

Noisy Outdoor Air Conditioning Unit

Not all outdoor unit noises mean the same thing, and the type of noise usually points straight to the cause before an engineer even arrives.

Air Con Tripping the Electrics

When an air conditioning unit trips a breaker or RCD, the fault is almost always within the unit itself rather than the household wiring behind it.

Air Conditioning Not Turning On

A unit that shows absolutely no signs of life is usually a power or control fault rather than anything wrong with the refrigeration side.

Air Conditioning Icing Up

Ice on an air conditioning system is a symptom, not the fault itself, and running the unit through it can make the underlying problem worse.

Signs of a Refrigerant Leak

Refrigerant leaks rarely announce themselves clearly, and usually show up as a gradual decline in performance rather than a sudden dramatic failure.

What Air Conditioning Error Codes Mean

Flashing lights and displayed error codes are the system telling you roughly where the fault sits, well before an engineer even connects test equipment.

Weak Airflow From Air Conditioning

Weak airflow is often the earliest warning sign of a bigger problem, and it's worth acting on rather than just turning the unit up.

Cold Room Not Holding Temperature

A cold room that won't hold its set temperature puts stock at risk quickly, and the cause is usually one of a short, predictable list.

Display Fridge Icing Up

Frost building up inside a display fridge is a visible symptom of the unit fighting a losing battle against warm, humid air or a stuck defrost cycle.

Commercial Ice Machine Not Making Ice

An ice machine that's stopped producing, or is producing far less than usual, is a fast-moving problem for any bar or hospitality business, but the causes are usually identifiable quickly.

Cellar Cooling Running Too Warm

A cellar running a few degrees warmer than it should can be enough to affect beer quality and cause cask issues well before anyone notices a total system failure.

Commercial Freezer Running Constantly

A freezer that never cycles off is working far harder than it should, and beyond the noise, it usually means higher running costs and faster wear.

Air conditioning troubleshooting checklist

A handful of simple checks can rule out the easy causes before you book an engineer, and a clear symptom guide tells you roughly what you're dealing with.

Air conditioning condensate drainage explained

Every air conditioning unit produces water as it cools the air, and where that water goes matters just as much as how cold the room gets.

Where to put an outdoor air conditioning unit

The position of the outdoor unit affects noise, efficiency, neighbour relations and even whether planning permission is needed, so it's worth getting right first time.

Electrical requirements for air conditioning

Air conditioning installation involves proper electrical work as well as refrigerant work, and understanding the split between the two avoids confusion and delays.

Air conditioning remote and settings guide

Most air conditioning remotes offer far more control than people realise, and using the right settings improves comfort while keeping running costs sensible.

Catering fridge or freezer broken down? What to do first

The first half hour after a catering fridge or freezer fails decides how much stock you save, so act on the food first and the fault second.

Air Conditioning Installation Cost: What You Are Paying For

Short answer: the cost to install air conditioning is set mainly by how many indoor units you need, what type they are, and how hard the pipework and outdoor unit are to fit.

How Much Does It Cost to Run Air Conditioning?

Modern inverter systems are far cheaper to run than older units — here's what affects your electricity bill.

How Long Does Air Conditioning Installation Take?

Most single-room installs are done in a day — larger or more complex jobs take longer.

What's Involved in an Air Conditioning Service?

A service is more than a filter wipe — here's what should be checked and what changes the price.

F-Gas Regulations Explained for Business Owners

If your business runs air conditioning or refrigeration, F-Gas rules bring real legal duties — here's what they mean in practice.

Do You Need Planning Permission for Air Conditioning?

Most domestic installs fall under permitted development, but conservation areas, listed buildings and flats have extra rules.

What Affects the Cost of a Cold Room Installation?

Cold room costs come from four main areas: the panels, the door, the refrigeration pack and the floor or groundwork.

What a Planned Maintenance Contract Actually Covers

A good maintenance contract is scoped to your equipment, not a generic package — here's how we set one up.

What to Expect From an Emergency Callout

When equipment fails unexpectedly, here's how we triage the call and what happens once an engineer is on site.

How Air Conditioning Warranties Work

Manufacturer warranties are valuable, but usually come with conditions around installation and servicing you need to meet.

How to Choose an Air Conditioning Contractor or Installer

Short answer: choose a contractor who is F-Gas certified, surveys before quoting, puts the price in writing and can look after the system afterwards.

Retrofitting Air Conditioning in an Older Property

Period properties bring specific challenges for AC installation — here's how we work around solid walls, lofts and conservation areas.

How often should air conditioning be serviced?

Once or twice a year covers most systems, but comms rooms, kitchens and dusty industrial sites need more.

Planned maintenance versus reactive repairs: which actually costs less?

Reactive repair looks cheaper until you count downtime, stock loss and the shortened life of the equipment.

What a commercial refrigeration service should include

A real refrigeration service is measurable work with recorded readings, not a quick look and a signature.

Repair or replace: how to decide on an ageing system

There is no magic age at which a system should be replaced. There are four questions, and the answers usually make the decision obvious.

Air conditioning energy efficiency ratings explained

The letters and numbers on an air conditioning spec sheet do mean something useful, once you know what each one is actually measuring.

Reducing your air conditioning energy bills

Most of the easiest savings come from how a system is used and maintained, not from buying new equipment.

Air conditioning filters and cleaning: what owners can do

A small amount of regular owner-level cleaning keeps a system running well between proper services, provided you know where to stop.

Spring air conditioning start-up checklist

A few checks before the weather turns catch most of the faults that would otherwise surface on the first genuinely hot day.

Air conditioning lifespan and replacement planning

Knowing roughly when a system will need replacing lets you budget properly instead of facing an unplanned failure and an emergency decision.

The air conditioning installation process, step by step

From first enquiry to a working system, a proper air conditioning installation follows a predictable sequence that's worth understanding before you commit.

Ice Machine Installation: What to Expect and How to Prepare

Short answer: an ice machine needs a cold water feed, a proper drain, a power supply and room to breathe; get those right and the fitting itself is straightforward.

Cellar Cooler Installation: What to Expect

Short answer: a cellar cooler is sized to the cellar's heat load, fitted with the condensing unit somewhere it can reject heat, and commissioned to hold a steady cellar temperature.
