I am frustrated with the difference in temp when I walk into my master bedroom. My home is 3 bed/2 bath 1753 sq ft in Orlando, FL. The layout is a split plan. Garage is on left side of house and master is at right (i.e. farthest from the air handler in the garage). I recently had to replace the a/c and purchased a 3.5 ton Trane xr13 heat pump and 3.5 ton 2teh air handler (2TEH3F42A1000A). Unfortunately, the problem with the room being hotter was already happening with the former a/c unit as well. The master b/r and bathroom are connected without a door, and there isn't an exhaust vent to get rid of the steam from the shower. I will be dealing with that in short order. However, even when I air out the room with a lasko circular floor fan, the room still tends to be hotter. Also, if I close the door for a short while, the heat tends to build up in the master bedroom. My a/c repair guy advised that older homes (mine was built in 1991) weren't built with return vents to pull out the hot air. The room feels better when the door is left open and a fan is blowing cool air from the formal living room into the master bedroom. However, you can still feel the difference. My a/c guy took me into the attic and showed me that there was a spot where you could see the drywall above my bedroom. He advised that we could increase the size of the duct that feeds the 3 vents in my master bedroom. However, someone that just inspected our ducts for leaks advised against this, because it could reduce the air flow to other vents in the house. The last thing about my room is that the bedroom area is carpeted, we have two sliding glass doors which lead to the pool, and above the mirror in the bathroom we have a decent size semicircle window which the a/c guy advised us to cover up to keep out the heat. Any suggestions on upping the size of the duct or anything else major to make sure that this room gets as cool as the other rooms? BTW I also have a brand new ceiling fan with the blades sitting lower than a foot from the ceiling. Thank you in advance for your help.
