smokin5s Posted July 5, 2016 Report Share Posted July 5, 2016 HVAC guys, I'm hoping you can help out. For some reason, the master bedroom is always hotter than any other room of the house. We have a cold air return in the room. Is there anything we can do to regulate the temperature better in that room besides just turn down the A/C farther which will then make the rest of the house cold?

TTQ B4U Posted July 5, 2016 Report Share Posted July 5, 2016 in line fan to help boost the amount of air heading down that pipe. Quote Link to comment Share on other sites More sharing options...
smokin5s Posted July 5, 2016 Author Report Share Posted July 5, 2016 the A/C register blows hard... there's 2 in the master, 1 in the walkin and 1 in the on-suite.... all of them blow hard. Quote Link to comment Share on other sites More sharing options...
STEVE-O Posted July 5, 2016 Report Share Posted July 5, 2016 Seems like there is some kind of insulation problem if your getting cold air there in good amounts it's just not retaining it Quote Link to comment Share on other sites More sharing options...
SRTurbo04 Posted July 5, 2016 Report Share Posted July 5, 2016 Subscribed. My daughters room is the hottest room in the house with a easy 8+ degrees difference between downstairs and her room. As well as my master is a probably 5 degrees hotter then the downstairs. Quote Link to comment Share on other sites More sharing options...
Green Bastard Posted July 5, 2016 Report Share Posted July 5, 2016 Do you have the valve things (diverters maybe?) in your ventilation system? Might help to close some a little to the cooler rooms to help even out the temperature. Quote Link to comment Share on other sites More sharing options...
TTQ B4U Posted July 5, 2016 Report Share Posted July 5, 2016 Seems like there is some kind of insulation problem if your getting cold air there in good amounts it's just not retaining it and attic type ventilation. we had temp controlled attic vents added to help draw out the hot air which pools up top and eventually drops down into the rooms. once we had them added it evened things out nicely. Now there's maybe a 1-2 degree difference between upstairs and down. the biggest culprit for us was my insulated garage that would hold in the heat from the cars and it would eventually make it's way into our master bedroom above it. the gable vent on that side of the house now is like a dryer vent as hot air is blown out of it.

smokin5s Posted July 5, 2016 Author Report Share Posted July 5, 2016 Seems like there is some kind of insulation problem if your getting cold air there in good amounts it's just not retaining it I would agree except that it's the hottest by far in the winter as well... I checked to make sure we don't have any hot electronics running and honestly, in the bedroom, the only thing that's running, is we have an LED tv (low power and heat) my MacBook Pro, and my wife's iPad... everything else isn't turned on. Oh ya, and a ceiling fan is normally always running as well. Quote Link to comment Share on other sites More sharing options...

We do have insulation on 4 sides of the room... (2 sides are outside, we insulated the wall between our bedroom in the kitchen for sound deadening, and the other side is the on-suite and walkin closet which are both insulated as well) Quote Link to comment Share on other sites More sharing options...
Duff1647545513 Posted July 5, 2016 Report Share Posted July 5, 2016 Toss a mini-split system in there and you'll have zero issues cooling it Quote Link to comment Share on other sites More sharing options...
Turbs3000 Posted July 5, 2016 Report Share Posted July 5, 2016 What is below these rooms and they are on the 2nd floor correct? Quote Link to comment Share on other sites More sharing options...
TTQ B4U Posted July 5, 2016 Report Share Posted July 5, 2016 Toss a mini-split system in there and you'll have zero issues cooling it ^^ for sure. Our neighbors put a recessed one in the ceiling of their sunroof and it's comfy year round. Quiet too. Quote Link to comment Share on other sites More sharing options...
smokin5s Posted July 5, 2016 Author Report Share Posted July 5, 2016 no idea what a mini-split is.... And the master is on the ground floor... we have a finished basement below it, so there is insultation, carpet padding, carpet, and drywall between us and the room below us Quote Link to comment Share on other sites More sharing options...
spankis Posted July 5, 2016 Report Share Posted July 5, 2016 Close off the walk-in, and dial back the flow (assumed adjustable registers/diffusers) on any rooms that are colder. Prioritize reducing flow on basement diffusers, as they are below the master and nearer to the furnace. Static pressure may be an issue. There is only x amount of static pressure by your blower fan, and the master may be ducted strangely and causing a deficiency. Also look up "short cycling" with respect to diffusers and return intakes. You mention three supply diffusers and only one return intake associated with the Masters Suite. Ideally the return should be located opposite from supplies, to promote circulation and true conditioning of the airspace. If the return is too near a supply, all that air blowing is potentially going directly back to the furnace and likely doing little good for actually cooling the room... Just a few other things to consider. Quote Link to comment Share on other sites More sharing options...
