It’s that time of year when the air conditioning machines are powering up. Air conditioning firing up for the first time in summer is a little bit like switching your central heating on for the first time in winter. You can tell immediately as the dust that has settled over the last few months starts to heat up.

When it comes to air conditioning though those little molecules of dust, pollen and anything else aren’t good for your unit. In fact, over time they can be detrimental to the performance of your air conditioning. If you want to get the most out of your air conditioning unit you should get it inspected and maintained regularly.

First you should have the filters cleaned. Filters prevent the unclean air from getting through but over time dirt will build up reducing the amount of air flow and increasing the energy needed to work. In some systems the filter will be reusable but in others it will need to be replaced.

The typical office air con unit has two important coils, an evaporator coil and a condenser coil. These too can collect dirt over time. Once covered the coils can become less efficient and become insulated by the dirt. A routine maintenance inspection should attend to these issues. Furthermore , aluminium fins on the coils are often bent quite easily reducing airflow, but you can purchase a fin comb from many building suppliers in order to alleviate this issue.

Finally during the winter, when the air conditioning unit is not being used it may be worth covering or removing in order to prevent it picking up further dust, helping to maintain its efficiency for longer.

I hope that’s a useful guide. In the meantime let’s do a Sun dance and pray for a little more warm weather.
