Though there can be a bit of wiggle room, generally speaking, you should have your air conditioner serviced twice yearly: once in the fall and once in the spring. This is to ensure that it's clean, that its parts are in good shape and that it's operating as optimally as possible.

So how frequently should you service your air conditioner? Heating and cooling professionals say that even if you do not suspect that your air conditioning unit has problems, you need to have it serviced and inspected at least once every 3 months. This will ensure that it operates at maximum efficiency.

Aircon servicing includes a general inspection of the components to find flaws or malfunctions. During regular maintenance, aircon parts and filters are cleaned.

The frequency of cleaning depends on various factors such as usage, the environment, and the unit type. As a rule of thumb, we recommend availing an aircon cleaning service every 3 to 4 months for residential units. For AC units used in businesses, aircon cleaning should be done at least every 3 months.
