Split Air con

Exactly. You’re spot on when you look at it from an initial outlay And likewise you’re absolutely bang on when it comes to an economical repair down the line. Overall through the life time of the unit/system you’re costing yourself more money for a far inferior product. This will be further amplofifed when these latest increase comes in October.

I doubt the difference in running cost will be that extreme. Besides I’m lucky enough to have solar and a battery so running cost are minimal for me.

First google link - all be it domestic white goods, it’s just to emphase the difference between running cost, an A/C is pretty much the exact same system with a fridge freezer, rather than a small box an entire room - £500 as above to a ’premium’ £1,500 unit. There’s also been further improvement with R32 over R410a, add to that additional benefit is of increased COP of a better more efficient heat exchanger since energy prices have increased. Again further saving money.

Look dude no one is saying a top of the range unit will not be more efficient. Of course it will be but I just doubt it will make as much of a difference as you claim it to be. Posting a link on kitchen appliances is next to useless. Yes that new fridge freezer will save you money over the course of 5 years but the savings will be totally wiped out by the cost of the unit itself with no guarantee of reliability beyond warranty. False economy.
 
Had a week of back and forth emails with various companies, quite a few giving me estimates from my measurements/requirements/explanations, varying from around £3.5k to £4.5k for a multi-split system with 2 indoor units, requiring me to arrange a sparky on top of that for a dedicated circuit. So that was all coming out way above my expectations, wasn't really wanting to pay more than £3k for it.

Had a local guy come out this morning (Spalding Air Conditioning), done measurements, discussed requirements etc, really helpful and knowledgeable guy, had an email come through this evening with his quote coming in at £2.7k, including electrical works and a conctrete slab for the outdoor unit. Very happy with that indeed. Accepted the quote straight away, he said should be able to get it fitted in 2-3 weeks.

He's quoted for Mitsubishi Fujitsu units with Wifi - Indoor Wall Mounts x 2 - ASYG09KMCC, Outdoor Condenser Unit - AOYG18KBTA2. Which look good to me, R32 as well.

Really looking forward to it now. My portable has served me very well for the past 10 years but it's finally time to have proper AC and I cannot wait :D

We always include a “free” years service. Industry standard afaik, worked for 5 different companies.


Wrong. Long story short, running costs are far lower and COP is lower. Similar to the whole issue of getting a decent fridge freezer rather than the cheapest. Over the life time of the unit works out cheaper. Which, bbc etc all have multiple articles regarding this - even more so with the recent increase in price.

Cheap units like those gee units are absolutely garbage. They awful, you can’t get spare parts. Their electrics are rubbish. Their air diff are woeful while this on the face of it won’t mean anything to anyone wanting an A/C in a home office or what not. Having a unit that runs at a low COP and having the ability to give you an air off of 3-6°c on cooling or 45°c+ on heating (daikin, mitsi electric - not heavy) is far superior than a cheap unit or portable. Anyone itt can stick a thermometer on it can confirm. Gets to the required temp far quicker then can free roll, newer units will even cut the fan off on cooling to save energy.

The bit you say about the air diff being woeful - would you mind clarifying - are you talking about the amount the indoor unit on the cheaper versions is able to drop the outlet emperature by i.e. how cold it feels when you're stood on front of it?

I've wondered if that was something that is quantified as you never see it in any specs. Mine works, but ideally I'd like it to blow 'colder air'

Yeah, you’ve nailed it on the head. The heat exchangers (evap coils) are far better, so the air is much colder, so in turn will bring the room temperature down quicker. Then can just recirculate the air in the room being more efficient than one that has to run for the entire time. Latest gens will now even just cut off the fan completely to be green (they’ve always done this when on heating mode as people will ’feel’ a draft when it blows air on them at room temp rather than warm cosy air, once it’s reached the desired temp) - had to change the settings a few times in peoples home gyms as they want the effect of air blowing over them.

A random example being lets say the room is 25°C and you stick it on cooling, regardless of the temp you select whether it’s 17 or 21 a good unit will be able to blow out cold air at under 8°C, generally will be lower. Worth noting it doesn’t blow air out at the set point temp. Whereas the cheaper ones even if the room is 20°C and you stick it on 17°C you’ll like get around 10°C off and it’ll take a while even on full pelt in order to bring the temp down.
 
Install today. Guys have been amazing, clearing up as they go, asking on everything if theres an option, giving advice based on their experience.

Nice! Mitsubishi Electric? Mine are the LN25 range which really look great.

Due to increased elec costs though sadly they're off most of the time, I'm hoping to get them more operational again when I can offset with solar though.

They're good as a cooling solution though as the weather heats up, and I use the heating mode in winter sometimes which does work well.

Happy to be schooled but it just makes no sense to me to install the isolators in a place which makes them completely inaccessible. Apart from not understanding the logic behind it, I’d have thought that there are regs against that as well.

I'd agree with that tbh, wonder why they didn't set them lower down.
 
Getting a 7kw installed at my wife's salon. About £2k excluding wiring, but my sparky can do that easy enough as he left capacity on the wiring he put in.

This is the model: Mitsubishi SRK71ZR-W Wall Mounted System.
 
2 weeks today mine's being fitted. Got the day booked off work just in case, plus need to help keep the dog out their way. Looking forward to it now.

Also considering some DIY solar to help offset the running costs during the day.

It was my request actually, just wanted them out the way as we have ladders and other bits we hang on this wall, but I can turn them off at the fusebox in the garage. Pretty sure the isolaters are just for them to flip off when they do the service/maintenance.

Install nearly finished, all units tested and working, so quiet theyre basically silent. Happy with the overall workmanship. They just miss one final bend in the ducting which they are coming back next week now to put on.

3 units upstairs as per the last post, and they bring the rooms down to temp in minutes.

Its already bliss, cant wait until the middle of summer.

Well first night with AC.

I am usually a hot sleeper, so put the AC down to 17 degrees and went to sleep. And wow, probably the best nights sleep I have had in years. Usually id open a window but by early morning passing traffic / birds in the trees just outside the windows would wake or disturb so window gets closed and then baking hot.

But to just have silence and cool all night... absolute bliss.

Anyone on the fence on getting AC, just do it, and enjoy it.
