That is.. shut down the heat/ cooling registers to the rooms no one currently occupies...or will it strain the hvac system?

    As long as your air intake is in an open spot and your filters are changed regularly, there shouldn’t be any strain.
    If you live in an area where pipes freeze, you should make sure no piping goes through the cold zones though.

    it won't actually 'strain' the system, but isn't very effective method reducing heat/ac costs -- having good air circulation is better to maintain regulated temperatures.

    You can adjust the registers in each individual room and shut the door to the room to minimize the airflow through the vents; however without proper air circulation you could create a breeding ground for mold and mildew.

    Holly, has the answer you need. It can cause mold and mildew, and when that happens it's hard to get rid of it, if you even can.

    thanks!

  • Depending on where you live, you could end up with a very expensive mold remediation or burst pipes. Most heating systems are designed with the idea that all the rooms will be heated. If this is about saving energy/money keep the heat on in all the rooms, only turn the thermostat down a degree or two. Then add an area heater to the room you spend the most time in. On cold nights, make sure you leave cabinets under the sinks open so the air can circulate. I live in NC and no one should ever close off the heat in rooms or they will develop mold on, in the walls and furniture... not worth the savings on heat or AC to develop mold!!!

    usually I have nose bleeds du to the very dry air....not much moisture in air here.

    My dad closes vents on rooms he isn't using. Your pipes aren't going to burst if there is only a 10 degree difference or so in room temps. Build nice big fires in your wood stove or fireplace. I have never had a mold problem doing this. If you have mold you need a dehumidifiyer to get the excess moisture out of the air. Use exhaust fans to help eliminate moisture.

    Won't strain the system, but won't save any money. The thermostat will still turn on and off based on the setting. The rooms will just be cold or hot and a great breeding ground for mold. Actually the closed of rooms can still transfer heat or cold to the surrounding rooms and your system could run longer to balance the air. As for the dry air you can get a humidifier to mount on your furnace or a free standing one.
