Refrigeration runs 24/7 and is often the biggest single electricity user in a commercial kitchen or shop. The good news: a lot of that cost is avoidable. Here's where the savings are.
Keep the condenser clean
A dust- and grease-clogged condenser can't shed heat, so the system runs longer and harder for the same cooling. A clean condenser is the cheapest, biggest efficiency win there is.
Fix the door seals
Perished gaskets leak cold air and make the system work overtime. New seals are cheap and pay back fast.
Service it regularly
Correct refrigerant charge, clean coils and working controls keep a system running at its designed efficiency. A neglected system can use significantly more electricity for the same job — so planned servicing usually pays for itself on the bill.
Right-size and modernise
Oversized or ageing equipment running old refrigerant is expensive to run. When it's time to replace, correctly sized modern plant — and well-specified cold rooms — cut running costs sharply. A TM44 inspection will flag inefficient air conditioning too.
Good habits
Keep doors shut, don't overstock airflow paths, and don't load hot food straight into a chiller. Small disciplines, real savings.
Frequently Asked Questions
What's the single biggest refrigeration energy saving?
Cleaning the condenser. A clogged condenser forces the system to run far longer than it should — a clean often cuts running time immediately.
Does new equipment really use less electricity?
Yes — modern, correctly sized systems on current refrigerant are markedly more efficient than old, oversized units, and the saving shows up every month on the bill.
