You can spec the external unit to be big enough for any future needs at minimal cost. Certainly a lot cheaper than deciding in 2 years you need another bedroom or living room adding but finding out the external unit doesn't have any spare connections or isn't big enough to cope.
Yes that's what we are doing so we can install a separate unit later if we want. However upgrading the external unit isn't a minimal cost, approx £700 per additional unit. Still cheaper than a couple k for a new external unit though.

That seems a lot and nowhere near the extra I paid to go from 2 to 3 (1 spare). I was essentially able to get away with the same size unit, just different models. Maybe if you need to go up a model or 2 it costs more.

Yes sorry we are also going up a model so from 2 to 3 units and the next step up in capacity as the 2 take it to max.

So a 5kw + 1.5kw installed with capacity to add another 1.5kw in future means we are going from the daikin 2mxm50 to the 3mxm68 I think.

Apologies if this has been answered before. I’m ok with the house during the day as we can open all windows and doors and let the breeze do its thing. It’s at night we struggle. We now have a 7 month old and we can’t have his window open at night due to intermittent road noise.

Would a single unit split system work in the landing, with the 3 bedroom doors open? Or is my thinking a fail as I’m cooking a room I’m essentially not living in. I’d say a twin unit is not worth it as it’s not a joke we are looking to stay in. I’d not I’d go triple unit, both beds and lounge.

The feedback I’ve always seen is that it won’t distribute very well into the rest of the house, but I fail to see how it wouldn’t atleast help.

If you have access to a suitable outside wall, perhaps try the all in one units posted abojt and available from Appliances Direct? £700-800 depending on how much they’re price gouging due to heat! Cheapest option imo.

Babies like white noise (mine did, anyway). A portable may be the cheapest way to go, the sound it makes could actually be helpful, and it could be ducted to a panel to the open window if it has an aperture that could take a panel (sash windows are ideal for this).

Just dipped my toes into AC & needed to get the Mrs onside.
I want the lounge & bedroom next they are above each other.
Starting with a single unit in our L shaped sunroom, been an easy sell to wife in this heat. Takes the internal temp down from 28c to 22c in no time & when we had a few cooler days able to heat.
Off the sunroom we have the kitchen & double doors. Our dog can push these open if not secure & if we don’t notice the system can easily start to cool more rooms.
Like with solar & battery systems demand is crazy currently & prices have shot up!!

Grumps.

We have one in the end bedroom and if doors are left open, will reduce the temps on the landing and the other bedrooms if it is put on early enough in the day.

We did exactly this two years ago. Our house is a 3 bed 1930's chalet style house with the bedrooms effectively in the roof; in previous summers the rooms wouldn't drop below 30 during a heatwave for most of the day even with curtains shut during the day and windows open a night. I fitted a 2.5kW split in the landing and even during the 37C we saw last summer all of the upstairs went no higher than 23C in the day and kept at 21C at night. It's obviously not as efficient or as effective as a split in each room, however with a curtain across the top of the stairs at night to keep the cool air in it works perfectly well for our needs- a good night's sleep!

I would without question do the same again if we moved house.

The trick is to overpower it if doing the above. We have a split each in the children's bedrooms at the top of the house (third floor), and they are overspecced for the rooms.

If you leave a bedroom door open, one alone will cool the room, the stairs and second floor landing. Not efficient running like this, but it does work.

Agreed. I think ours is rated to about 150% of the space it actually cools and although much less efficient than splits in each room it's only costing us about £2.50-£3.00 per day in the height of a heatwave with current prices. I just couldn't justify the cost and installation effort of 3 splits, so although it's compromised it's still orders of magnitude better than the portable it replaced.

Brilliant. Thanks all.

We have the same, one unit on the landing.

As long as the doors are open it works fine thumbup

I have a split unit in my bedroom a 3.5kw unit. It kept the bedroom at 17 degrees last night for 12 hours the running cost was 1.7kw so about 35p on my electric rates.

The Argo and Electriq units from Applicances Direct, has anyone had any actual issues with them?

Having spoken with 2 AC installers they both pushed Mitsubishi, Fujitsu etc my way and said the Argo etc are poor quality and always have issues. I think its more of a sales pitch than anything as I don't recall anyone having faults with the systems on here?

One has quoted £600 to fit or £1200 supply and fit (price are per unit). Waiting on another quote. It may just be more effective for me to get another portable one as I don't see ourselves staying in this current house for more than another 2 summers if that..

I've had Electriq and TCL units from appliances direct for four years with no issues. That said, they are occasional use rather than being used all day, every day.

The guts of them (inverters etc) are Panasonic, I believe, so hopefully the main stuff is pretty standard mass produced stuff.

But as I bought stuff and did installations myself with a friend, so avoided big installation costs. If going the official route and most of the cost is the installation, then upgrading to Mitsubishi etc may not be much of a leap.

Have ordered a 2.5kW Daikin split through a mate in the trade, which should be here Thursday. Be nice to have that up and running before our next wave of warm weather as i'm getting fed up of sitting in a 29 degree office now....and likewise, running a 2kW convective electric heater in the winter, which I invariably leave on costing me many pennies.

If you had the opportunity to sell a product with a cast iron guarantee, excellent aftersales support and low risk of a warranty claim (installers get almost no labour allowance payment for warranty claims) vs. one with no reputation for any of those things and therefore taking the risk yourself, which might it be? Remember that unlike your car, the owner won't be bringing it to you for repair either.

In the past, when selling cheapo portables, the supplier was unable to get us any parts and no stock for a replacement unit. We ended up refunding the customer. So labour and travel costs for original survey, delivery and set up, return to site when reported not working and finally collection. We stopped selling cheapo portables

Points taken thanks both. It comes down to what risk profile I am comfortable with. I might just considering the option to self install as between my father and I we can get this installed and just need an electrician in to do that wiring up.
