Power Consumption

Calculation formula used;


E(Kwh/Day)= P(W) x T(Hr/Day) / 1000 (W/Kw)


E energy

P Power

T Time

These figures are based on a system running @ 98% efficiency 24hrs ( Clean filters / Seals etc.)

Small Fridge/Freezer:

200W x 24Hr/ 1000
= 4.8 Kwh/Day.
=144 Kwh/Month
=1752 Kwh/Year.

Large Fridge/Freezer:

700W x 24Hr/ 1000
= 16.8 Kwh/Day.
=504 Kwh/Month
=6132 Kwh/Year.

These figures are based on a system running @ 98% efficiency 12hrs ( Clean filters / Coils etc.)

Small Air conditioner:

3.5 kW x 12Hr/ 1000
= 42 Kwh/Day.
=1260 Kwh/Month
=15330 Kwh/Year.

Large Air conditioner:

10 kW x 12Hr/ 1000
= 120 Kwh/Day.
=3600 Kwh/Month
=43800 Kwh/Year.

As the figures above show one small fridge/freezer running efficiently will cost around (Guided cost of 18.9p/Kwh. as of 2022.) x 4.8 Kwh/Day = £0.9072p.

If the system isn’t running efficiently these costs can vary greatly per day usage.

Having your systems cleaned/maintained regularly will ensure that they aren’t costing you more than they should and the savings will increase if your unit is able to reach temperature quicker and maintain it for longer periods.


John provided an excellent service. Nothing was too much for him. I would highly recommend him and R4nk1n!

I can’t say enough good things about the service we received from John at R4nk1N! 🙌🏽👏🏽 He attended to our freezer fault at the Laughing Duck Cafe on the same day, and in no time had us up and running again. Not only that, but he also serviced our other freezers at a very reasonable cost. We were blown away by his professionalism and attention to detail. Highly recommended for anyone in need of top-notch freezer repair services! 👍🏽👍🏽


Great service. Definitely recommend

After having a few companies out to fix a fault with my AHU and refrigeration system who failed to repair the fault and priced me for new units, John was referred to me by a friend and was quick to come out and actually managed to repair both units and advise for maintenance schedules which I’ve now booked in. John was very polite, knowledgeable and has great attention to detail and resolved problems other companies failed to sort.
