So i been unhappy with the cooling in my house for quite some time now
been living in this house for a year , where i stay is extremely hot and humid all year round.
the space is quite large
7M X 15M and 3.5M height ceiling
i have 2 ceiling Hitachi units , model RAS-B36TNTBNH1
these are 34k BTU inverter 1phase units
they are both being turned on at the same time, never alone, the cooling just not enough unfortunately, had them cleaned, no difference
electricity bill are quite high because of it (500$ a month) , my smart home system shows about 7-8kWh when they are running,
from what i noticed the outdoor units are cosntantly running, they should reach a temp and then start/stop right ?
should i change them to bigger units ?
one last parameter to consider is that this space has giant glass sliding doors instead of walls on one side(south east), so sun is probably making things worse, i was thinking of maybe getting those windows tinted with UV blockers ? although i wouldnt want to get them too tinted as its facing our garden and pool.
please advice, whats the best way to go about it ?
