    Default Bedroom won't cool enough

    We just had a new ac installed. Bigger and more efficient. But our sons room still will not cool like the rest of the house. He does have a slidding glass door and gets sun most of the day. We live in Las Vegas and it is 113 today. We have solar screens on all the windows and on his glass door and we even put some heavy curtains on it. But to no avail. He has to use our portable swamp cooler in there just to get it comfortable. The rest of the house cools great better then ever and my electric bill was cut in half from this time last year. Anyone have any other ideas that we can do? We just do not know what eles to do.

    Sounds like the installer didn't balance the system... there is only a certain amount of CFM available and if the dampers aren't set correctly you're going to have rooms too cold/too warm.

    Thank you. I will give the man a call again and ask him that. He said over the phone a month ago that it was just because his room gets all day sun. I didnt think that could be since we did so much to help that.

    As an aside to the "bedroom won't cool enough" question and reply, has anybody had any experience with adding an "in-line" duct booster (not vent fans)to increase conditioned airflow to a given room? It seem like a logical and fairly simple solution (even to experiment with other balancing solutions). Or even if the homeowner simply wanted the quickest / cheapest fix. I don't need information on installation or hook-ups, just whether you think they work or not. Thanks ahead of time for your advice.

    Directing more air to this room will help. A "bigger" air conditioner may have the effect of satisfying the thermostat more quickly than your older unit. The effect is that the unit runs for shorter intervals compared to your old unit. The unit may not be running often or long enough to cool this room.

    If they installed a bigger Condenser it could be short cycling or running for short time and shutting off continually, it has to be sized correctly to cool properly. Also is there a return in that room? I don't know how your A/C is set up, one central return or one in each room. If you have a central return and the bedroom is down at the end of the house you may not be getting all the hot air out of the room. If there is no return in that room have one put in, you can never have to much return air but make sure it is pulling out at least the correct amount of the supply. Good Luck!!

    Sounds like the installer didn't balance the system... but for now put the fan control to the on position. Run it 24/7 and see if that works.

    Bigger isn't always better when it comes to A/C. As Sten said, it may be that the unit is short-cycling due to oversizing--this means that the thermostat gets satisfied and shuts the unit off before the bedroom has had a chance to cool off.

    You can check to see if the room has adequate return air by standing in the hallway outside his room and closing the door while the system is blowing air, and feeling along the bottom of the door for air that might be rushing out of the room into the hallway. If so, the room needs an unrestricted path for its supply air to return to the blower.

    If the supply duct to the bedroom is undersized, more return air will not help.

    Balancing the entire system might help by reducing airflow at other registers, thereby forcing more air back to his bedroom. But if the duct system is undersized for the amount of air that the system is meant to deliver, balancing will not help much because it may result in lesser total airflow.

    Running the fan continuously will help average out the temperature throughout the house in between times when the condenser is running. If you do that, the fan speed for "fan on" should be set to the lowest speed, which is done by a professional using the fan's speed taps.

    An inline Duct Booster is usually used when the supply runs are very long. When you getting uneven airflow a non balanced system is usually the problem.

    Howdy is there an air space under your sons door? or is it left open? allowing the air to be able to move out of his room when the air is on is important.. Perhaps adding another duct to this room from the air unit may also help too.
