Aircon / HVAC suggestions?


Well-known member
TL:DR - suggestions for portable or permanent aircon units please

My dedicated room is roughly 4m by 4.5m or 13ft by 14.5ft give or take.

Since I put everything in; carpets, heavy curtains, the silent fridge, star ceiling, plus all the equipment, the heating hasn't been on once. And the room is never below 20c unless you leave the windows and the doors open.

Close the windows and doors (the doors is a must regardless) then the temp after watching a film can hit 25c, more if more than one person and again rises with prolonged viewing. Once it hits 27c you don't really feel like watching anything, let alone sit on leather seats! :)

Being in Scotland, aircon wasn't really in scope but certainly is something I would consider now - although might be hard to retrofit a permanent one now. Anyone have any thoughts or suggestions on how to solve this dilemma?

Honeywell HL10CESWK has come up a few times in searches. Seems to be OK and roughly 49db so not the end of the world but not great. Daikin have something called EMURA which says 24db but I haven't worked out whether that would work or not yet.

Where is the heat mostly being generated? Most of our equipment except the projector is located in a seperate area outside of our theater. We had a heat problem from our projector (when we would close the doors for watching movies). This was solved by adding a wall fan that pulls the heated exhaust from the projector into an adjacent hallway outside of the room. The quiet fans operation is integrated into our theater control system. Of course a seperate HVAC system can’t be beat. SJ

I had to install one and I live just outside Geneva.. it was much needed, you describe exactly what I used to go through.. If you can, go for it.
Mine is a Daikin Bahut - FVXS25F installed in 2013, very silent and very happy with it.

Thanks both. SJ - rings a bell that. Maybe we discussed this before (although I did search before I posted). I think it’s purely the lack of air movement and basically everything cooking. The PJ is built into a bulkhead that has a fan of sorts to do that but it didn’t do anything for the core of the room

@telem Nice one. Will have a look. I think it’s almost a must when you’ve gone all in, and would certainly be on the list if I were starting over. Not really summer yet either, it’s great in the winter tho, the log burner is well put out haha

Have you looked into possibly installing a Mini-Split in your room? I have one in the equipment/concession/restroom area adjacent to my theater, and it is absolutely whisper quiet. The outdoor unit is exceedingly quiet as well.

Awesome! Thanks Mike. No, I hadn’t but this could fit the bill nicely too going by google 👍🏼
