I’m seriously considering ac, this house is like satan’s lair! Even in winter it’s quite a warm house, I used to think it was lovely and cozy but peri me thinks it’s a bleeping ovenOur bedroom is like this. Double aspect, but sash windows and we live on a main road so don't open them. And the sun is on our bedroom in the morning. We very quickly invested in an aircon unit which has been an absolute godsend! Luckily the downstairs of our house is like a fridge!
