Q:

How many BTUs do you need to cool a room of 435 square feet?

A:

To effectively cool a room, it is necessary to have an air conditioner with the correct capacity. To cool a 435-square-foot room, a 10,000-BTU air conditioner is needed.

Many people believe that an air conditioner that is too large for the intended amount of space provides better cooling, but this is not true. An oversized air conditioner wastes electricity, and it does not cool as effectively as a unit of the correct size. An air conditioner that is too large lowers the temperature in the room, but it does not remove as much humidity as a unit of the appropriate size.

    How do you circulate hot water in a baseboard heating system?

    A:

    To circulate hot water through a baseboard heating system, first bleed the system by removing all of the air, then turn the thermostat up all the way for 30 minutes one by one through every level of the building from lowest to highest. By turning the heating up all the way in this order, hot water will flush through the entire heating system.
