I had one installed eight years ago when I bought my house. I’ve used it to heat the entire place, but this winter, I struggled to maintain even 20°C indoors on really cold days.

Well, today I finally brought my air compressor inside and gave the guts of the indoor unit a thorough blasting - and now it feels like an oven in here. I’ve been lowering the thermostat all day, and it’s still way too hot. It literally feels like it’s putting out twice the heat now. I was expecting a slight improvement, but nothing like this.

    I don’t think anyone is suggesting you take a hose to your indoor units. How on Earth you would contain the splashback is anyone’s guess.

    Use your hose on the outdoor unit. I use compressed air on the indoor ones, like OP. You can buy the cleaning foam stuff, too. Probably from whoever made your split system, in fact. I’ve never found it to be necessary, though.

      I mean, I guess that would work, but why wouldn’t you use a vacuum cleaner? I mean, if you’re hitting it with compressed air, now all the dust is all over the room.

        Compressed air combined with a vacuum cleaner to capture what the compressed air blows loose.

        It’s impossible to get a vacuum in all the nooks and crannies. Especially between the fins. Compressed air is pretty much the only option.
