How we calculate
An air conditioner that is too small runs at full power all the time, one that is too large keeps switching on and off. That is why we calculate per room.
Walls, roof and windows
The better your home is insulated, the less heat gets in. High ceilings mean more air to cool.
The sun
Sun through glass is often the biggest source of heat. Large west facing windows weigh heavily, and outdoor sun shading helps most.
People and appliances
Every person, computer or TV gives off heat. That is why an office or shop needs more cooling than a bedroom.
Heating separately
Do you also want to heat? Then we calculate the heat loss separately. The cooling load says nothing about how much heat you need in winter.
Good to know
How accurate is the calculated cooling capacity?
For each room we calculate with the floor area, the ceiling height, the insulation, the glazing, the sun and the heat from people and appliances. That gives a good first estimate. We confirm the final capacity during a site visit.
What is the difference between a monosplit and a multisplit?
With a monosplit, each indoor unit has its own outdoor unit. With a multisplit, several indoor units share one outdoor unit. A multisplit saves space on the facade, but not every combination is possible. We check that in the manufacturer's combination table.
Why don't you simply add up the capacities of the indoor units?
Because not all rooms need full cooling at the same time, and because every manufacturer has its own rules on which indoor units fit which outdoor unit. So the sum of the indoor units does not tell you which outdoor unit you need.
Can an air conditioner also heat?
Yes. An air conditioner is an air to air heat pump and can also heat. In severe frost its capacity does drop. That is why we calculate heating separately, based on the heat loss of the room.
Where does the outdoor unit go?
We assess that on site. We pay attention to noise, the distance to the neighbours, the length of the pipes and a neat finish. In an apartment, permission from the owners' association (VME) is required.
