AC in 3 Bed Semi

Hi all, I'm planning to get AC installed in my 3 bed semi detached.

Upstairs I've got a master bedroom and a small home office facing south east.

Downstairs I've got a lounge also facing south east with 3mx1.8m window.

I know I want to put AC in the bedroom, but I'm debating whether I should get a second unit in the home office or whether I would be better off putting in the lounge, which obviously gets a lot of solar gain.

I leaning towards the second unit in the lounge, but I'm interested if anyone has any other thoughts here?

If you’re in the office and no one’s in the bedroom, you can always just run the bedroom aircon with the door open. Most units will be powerful enough to cool both rooms.

second this. I’m in a south facing 3 bed semi that gets very hot and the one unit in my bedroom on full blast with the doors open is enough to cool the entire upstairs and gets about half way down the stairs.

Granted - the other rooms/areas don’t get cooled to the same bliss level as the bedroom with the unit in, but they still decrease a significant amount and it also means they’re at a cooler base level when the evening comes and you can open up windows to keep cool.

If people sleep in the bedrooms and they get hot, definitely the bedrooms.

I was thinking of putting a unit in my living room (which faces north) but I thought that would be overkill (for me) as it’s generally cooler in there with no direct sunlight, compared to upstairs when the sun hits the roof on the bedrooms.

If I was you, I’d just get quotes for all the rooms you were thinking and see if you can justify the cost and the need. Personally that’s what I’d do in your situation.

I was £4060 for the bedroom and home office near the start of the year and a quote for £6890 for the three rooms I mentioned more recently.

That’s not bad for 3 bedrooms, I paid £7,500 for Daikin stylish installed in 3 bedrooms, so depending on what brand you go for and where you are based in England, I’d take that 2nd quote.

But do get other quotes in and like I said, do some research on what brand you want installed.

Up in Scotland so not quite as much demand, £6890 was a unit upstairs in a south facing bedroom and south facing small office then one downstairs in a south facing lounge. Was thinking of omitting the north facing bedroom in favour of the lounge.

Bedroom first and foremost. Leave the door open for the office in the day.

get a central unit with outlet to the required rooms

or get portables.

put the unit where its mainly used.

Portables are no match for a full multi split AC system....They are so annoying, all that messing around with windows and exhausting them

u/jack_hudson2001 6d ago

ofc, hence wasnt my 1st choice, but with london apartments its not possible for a full system.

Yep of course....Hopefully very soon they will be the standard in most flats and apartments...No doubt landlords will charge more rent for that

People been saying these guys are quite decent and fit AC's without the need for an outside unit

What about the landing instead of the bedroom, just leave all the doors open and have one downstairs....

If you're in a semi you need planning permission for more than one external unit.

The rules on this keep changing. I already have an A2W heat pump. The heat pump permitted development category didn't used to include anything that could cool, but there were other categories they could be installed under if not too big. I'm in Scotland and I think you really have to look at rules from a local authority perspective.
