We could let you play with a little web site gizmo to try and work out an approximate cooling or heating load, or to give you an approximate price, but when we will do it for nothing - what's the point? - You must have better things to do? - We show you below - all you need is a calculator.

It is not difficult to work out approximate budget costs and loads, but it is best to talk to us if you have a serious project as we can advise more accurately, based on your building and how you use it.

So get your calculator out:

cooling load calculator

An approximate guide to working out cooling loads (if it cools and you use a heat pump - it will also heat you in winter as well) - tell me - What's a heat Pump?

For most offices, homes or shops:
Take the floor area of room or rooms in m2 (sq. m.) and multiply by 150watts. This will give you an approximate total cooling load in watts.

e.g. 3m x 4m = 12m2 x 150w = 1800w or 1.8kw

If the room or area does not suffer too much from direct sun radiation you could use a lower figure of 85w/m2.

e.g. 35m x 50m = 1750m2 x 85w = 148750w or 148.75kw

Computer and equipment or telecomm rooms can have a much higher load, for budgeting we suggest you allow 400w/m2.

e.g. 2m x 1.5m = 3 m2 x 400w = 1200w or 1.2kw N

Note that equipment rooms normally have high sensible cooling loads and ordinary air conditioners may not be suitable. - tell me - What's sensible heat?

Only use these guide prices to give you an idea of what you should budget for, contact us for a more realistic cost budget. Many factors affect the final price and there are many options available for most applications.

A mobile air conditioner will cost anything from £300 (approx.) to well over a £1000 depending on the cooling capacity, quality, functions and type.

The general cheapest cost to supply and install a split system room air conditioner is around £1300, again capacity, quality and functions will affect the price, as will the amount of time and materials required to carry out the installation in your premises.

For larger systems, serving many rooms or larger areas, budget costs are based on a price per square metre of the floor area. For general comfort applications, offices for example can range from £65 per sq.m for basic cooling only systems to over £150 per sq.m for the most modern heating and cooling systems.

Every application is different so contact us for the best advice.
