We have our Aircon cleaned around March or April because when everyone turns them on and realises how badly they smell in July all the cleaning services are busy.
YMMV But another fun AirCon fact*.
A few years ago we switched from running the air con hard at 20°C or so when we got home, having it turn off automatically late at night, running it hard in the morning and turning it off when we went out…
To…
setting it at a supposedly “high” setting of 27°C and leaving it on 24/7 (July to September)
The running cost was the same and it was very comfortable coming home to an already cool dry environment. We never felt the need to lower the temperature either. It was lovely.
*“fact”. I’m sure the condition of your home insulation, outside temperature and conditions, draftiness of windows and doors etc all play a role.
Where I live if you fall and injure yourself on an established hiking/climbing route, in season, you will be rescued for free (regular ambulance rides are free anyway).
If you climb or hike off track, out of season you might be charged for a helicopter ride or mountain rescue. As you can imagine it’s not cheap.
