Air conditioning – or more specifically, the temperature it creates, can be a source of tension and frustration in many offices and workplaces.

Set it too cool, some staff will moan they are cold. Switch it off, and some may complain they’re too hot.

Set it too high, some may be affected by the noise.

Sometimes, you just can’t please everyone.

So, if your air conditioning is causing friction in your office, or if you are planning on having a new system installed or upgrading your existing one, putting in place a robust air conditioning control strategy can go a long way toward stopping everyone from getting too hot under the collar.


Keep control of your controllers

A common problem when specifying air conditioning for large open-plan office space systems is when there are multiple indoor units on one outdoor unit.

In some instances, if more than one controller has been installed to operate different units in the same space, people can different controllers to different temperatures or modes which can lead to different units in the same space being used for both heating and cooling. Clearly, this is not going to work well.

In an ideal world, all controllers should be set the same, but if this is not possible, just make people aware of the issue and the best ways of getting their air conditioning to perform at its best. This might mean limiting the number of individuals who have access to the controller and ‘training’ the ones that do, giving them tips and ideas of best practice.


Changing rooms

Another common problem with air conditioning installs is where systems have been installed with multiple indoor units on one outdoor unit, but the indoor units are in different rooms and not a shared space.

As all units have to operate in the same mode, this might work most of the time, but there may be instances where users in different rooms wish to use different modes of heating or cooling and can’t.

When systems are installed in this way, there is always one unit that is treated as the ‘master’ so the return air temperature will be used from this unit.

However, the office this unit is in could quite easily be a different temperature from the other, users won’t necessarily be getting what they want from the settings they input.

Again, limiting the number of people allowed to access thee controllers and making them aware of the issue should help resolve and problems and keep your system running as it should.


Getting your ducts in a row

Finally, where ducted systems are used, they can be installed to receive their return air temperature from either the return air section of the unit, or a remote sensor can be installed.

However, if the incorrect option is installed, it can lead to problems as usually, the ducted units will be installed at high level, which is often concealed above a ceiling.

If you are sensing the temperature at this height, or of the ceiling void instead of the room, it is not very often an accurate measure of the room temperature, so the unit will not perform as you expect.

So, if you have a concealed ceiling or your ducting is to be installed at a high level, using a remote sensor at a more optimal height will give more accurate readings and help alleviate this problem.



There are many common office air conditioning problems which can be avoided by making a few simple decisions before your system is installed, which can be costly or disruptive to put right afterwards.
