Due to the reason I lack knowledge in air conditioning I asked a company that manufactures and sells a\cs to send a consultant to advise me on which air conditioner I should use in my room.
The suggestion he gave me is a ductless a\c with a BTU measure of 12,650.
I tried to learn about the quality of the suggestion and I found multiple sites that cite this table from energystar's site.
My room is 105 squared feet and is quite sunny so according to this chart a 5,500 btu a/c should be enough.
The suggestion by the consultant is very far from the estimation of this table and therefore I'm not sure what is the explanation. I'd like to understand which suggestion is correct to avoid the possibility of buying a highly non-matching a\c (either too strong or too weak).
Are there any other parameters, beside those that appear at energystar's site, that the consultant could take into account that result in this big difference?
For example I encountered a website that suggested that a hot climate could raise the required btu by 30%.
Is there any more information, about my room perhaps, that I can provide you to allow you to better answer my question?
I found this question. I concluded it doesn't contain enough information because:
- The calculator provided in one of the answers doesn't seem to fit very well to my single room situation (And when i tried it suggested even less than 5,500 btu).
- Some of the parameters listed there are also listed in energystar's site.
- Another parameter that was suggested was the climate. as I mentioned earlier this still doesn't cover the difference.
Information about the room
- it's size is 105 sqr feet.
- It has 2 windows of 8.7 sq feet each with double glass pane.
- The climate is rather hot in summer (from 23 c at night to 32 c at day).
- the door to my room is open during the day (which leads to the rest of the family house) and close during the night.
