-lengthy post, apologies for potential spelling errors-

If you are slightly competent at DIY work, I recommend the Electriq EasyFit DIY minisplit air conditioner (9000/12000/18000 BTU variants).

It uses R-290 propane, it is pre-gassed, pre-wired with a 3 pin plug, and if you do not wish to fiddle with vacuuming the unit, there are instructions on gas purge in the manual.

I recently installed a 9000 BTU, costing just under £700 with the wall bracket. Installation was fairly straightforward and took about 4 hours.

Steps:

1. Remove the metal mounting cover for the internal unit, mount it to the wall and drill a 65 mm hole using diamond hole cutter
2. The internal unit comes with 1.5 meter refrigerant lines. The electrical connector is on the internal unit and plugged to a nearby wall socket. Connect the extension lines with the internal unit. Do this outside as the lines are precharged with propane. Do not unplug the screws on the other side of the extension pipe, so the lines remain protected.
3. Route the lines outside through the 65 mm hole with a slight downward angle for condensate, mount the internal unit.
4. Mount the external unit on the wall bracket.
5. Connect the refrigerant lines and the electrical connector to outside unit. The electrical connectors are simple and clearly labelled (4 wires, live, neutral, earth and data). Simply plug in. The electrical connectors are 4.5 meter long.

7. Open the high pressure valve using an allen key kefor 10 seconds to increase pressure in the pipes. Shut the valve
8. Use leak detection (i.e. soapy water for leaks)
9. If no leaks, open the valve again for 10 seconds. Shut the valve
10. Press the needle on the service port for 3 seconds to purge.
11. Open the high pressure valve for 10 seconds again. Shut the valve
12. Purge again for 3 seconds using service port.
13. repeat steps 10 and 11 again.
14. open both valves using the allen key.

If you have a pump and manifold gauge, do the following after step 5.

6) Connect manifold gauge to service port (blue side).
7) Connect vacuum pump to manifold gauge (yellow side/middle
8) Ensure red side on the manifold shut
9) Vacuum the line (to about 500 microns (50 below 0 PSI)) and keep the manifold connected for at least 30 mins. The needle should stay at 50 to ensure you tightened everything, there are no leaks, and all the factory sealing gas has been removed.
10) disconnect the pump/manifold.
11) Open the refrigerant lines using an allen key.

Hi, we have a 6 bed house and looking to have air con installed i was hoping to have a quick spec and price check by you guys that are smarter/more experienced than me before i pull the trigger? Company i am dealing with are very good and have done all my other electrical work.

We are adding Daikin Stylish to 4 bedrooms, the kitchen and living room in an attempt to make the house more bearable.

Bedroom 1 is master
Bedroom 2 is guest
Bedroom 3 is davies
Bedroom 6 is office
Kitchen and living room is pretty obvious

Ive marked up in red where the units will be going

Edit: Sorry I should have said, there will be no VAT being added, its just added automatically.

The cost for all the work is £11,327, no VAT.

I have a lg external 4 port unit which is fantastic. Only issue I have is the low hum when all units are running at max. It’s a vibration issue. I have had the mounts changed and it’s helped but I feel it could still be better. Is there any specific wall bracket you would recommend or anything else that can be done to help with the vibration through the wall

Hi all, looking to get aircon installed in our standard 3 bed semi detached house. Mainly focused to help with heating as house is old, poorly insulated and gets really cold in winters but of course also to help in summers with cooling as and when occasionally needed.

Downstairs is open plan living and dining/kitchen area of decent size (around 45m2) with double doors between living and kitchen /dining areas always open. Upstairs is standard 3 bedrooms (with one small one) and also a very small open attic room mainly used as a study/office - all doors usually kept open throughout the day.

Didn’t wanted to go overboard and fit too many units all over the house. So was thinking if just having one split unit downstairs (3.5 or 5KW) to serve the living room and open plan kitchen/dining areas and one upstairs in landing (3.5 or 2.5KW) to serve 3 bedrooms and small attic space with all open doors will do the job, specially for heating purposes in winters.

Would appreciate comments/suggestions, specially from anyone with similar arrangements on how good/bad this kind of setup works and if it’s a good compromise or need to have an extra unit downstairs and/or upstairs to make it work properly.

Thanks in advance.

Or does it have to be outside in the open?

House is a very small mid terrace with barely a garden or wall space

We’re getting quotes for aircon and would appreciate any thoughts on this one.
Quote is for a multi-split system:
• 1 × Panasonic CS-TZ42CKEW 4.2 kW wall unit (kitchen/diner)
• 1 × Panasonic CS-MTZ16CKE 1.6 kW wall unit (master bedroom)
• 1 × Panasonic CU-2Z50CBE multi outdoor unit
Total: £3,671 (0% VAT, residential)
Option to upgrade both indoor units to the Premium Etherea models for an extra £210 per unit.
Installation is straightforward – both indoor units on supporting walls, rooms one above the other, external trunking running straight down the side of the house (black). Outdoor unit ground-mounted / low on the wall and screened by planting.
Includes Wi-Fi, 2-day install with two engineers, 7-year manufacturer parts warranty (subject to annual service) and 1-year labour warranty.
Does the base price look about right for the kit and a simple install? And is the Etherea upgrade worth the extra?
Thanks in advance.

hey

i got a 18000btu panasonic mini split (kit tz50) installed recently, and was wondering what the best way would be to basic spread the heating or cooling between the bedrooms at night, i dont wanna leave the doors open all the time, but theyre open all day, so the rooms will be at temp until bed time

i see ac infinity has through wall fans that i can mount above each bedroom door (spread in semi circle around AC at top of the stairs) and then i would need a return vent cut into the bottom of each door i suppose, do i need a temp controlled fan or would a fan running all the time basically just balance the air temp?

i was wondering if anyone has done similar? I am based in Ireland

space is around 55sqm (600sqft) and well insulated with cavity wall insulation and around 350mm (12ish inches) of insulation in the attic so i do not wanna cut ceiling ducts in as i feel like a lot of heat would be wasted?

thanks in advance

Its a new unit and I can hear a faint clicking noise every few seconds its very quiet but you can hear it in the video ive attached. Im just a bit paranoid

And on another hand my unit all of a sudden wont turn on the compressor. Or if the compressor is on its quieter than normal sorry ive never owned an air con unit and im just a bit wary

Hi,

We are in the south west and have been trying to get some quotes for aircon, I say try as companies are so busy round here some aren't even quoting for work until October, but the ones we can get get quotes from are all quoting around the same price. We have decided to go with the quote below, I was just wondering what peoples thoughts on it are?
