Split Air con

@DampCat We've had three indoor units (two 2.5kW and a 5kW) from an 8kW outdoor unit all Mitsubishi and they've been excellent since we got them in 2022. They tick along at around 700w energy use each and the outdoor unit is silent.

I've got it in one room, don't expect it to work miracles but it definitely helps

The stuff I got off was €12 a roll and it dropped the ambient temp in the south facing rooms we used it on by 2-3°C.

We used 5 rolls, and while it’s not the most relaxing thing to fit (think giant phone screen protectors), our is still giving that 2-3°C temp reduction 4 years later being having been exposed to 40°C summers.

As always, I would recommend shutters or an awning if those are possible as stopping the sunlight from reaching the window/doors is always the most efficient way to stop windows heating up.

Our kitchen unit is smelling a bit when it first comes on.

Will try these cleaners:

That's mould

It's because you are not drying out the system, everytime you run it in summer condensation builds up inside the heat exchanger and if you don't dry it, it causes mould

Either leave the system on 24/7, or if you insist on turning it on and off constantly, in summer after using it, let it dry out before turning it off

I’m glad I got a split unit put in my office space last year as it’s usable both for heating and cooling if necessary.

Only downside is it’s too bloody efficient and can feel too cold. :cry:
Even when I set it to 21c it feels like a fridge.

Depends how far away you sit from it. I find the further away you are from an aircon the better. Because the temp you set is a target temp for the room, not the temp of the air coming out of the unit, and you sit too close you get hit with cold air.

I tested this by setting my air con to 18c then used a thermal camera and the air coming out of the air con was 2c, and because the air is just 2c, you will feel ice cold if you sit right next to it. This is also why portable air con's make good coolers for computers, you can funnel the near freezing air straight in

How does one encourage it to dry out after use?
