Electricity Cost Comparison Chart
Whole-House Air Conditioner
Air conditioners turn on and off to maintain a desirable temperature. When this temperature is achieved, the unit turns off, no matter what humidity level is achieved. In addition, most whole-house air conditioners are unable to reduce the relative humidity lower than 60% which is outside the safe zone for pianos.
Whole-House Humidifier
Most furnace humidifiers have the same limitations as air conditioners: when the furnace has achieved the desired temperature, both the furnace and the humidifier turn off, no matter what humidity level is attained in individual rooms.
THE TEST: If your whole-house air conditioner and furnace humidifier are effectively keeping the humidity stable, the pitch of your piano will not go sharp or flat with weather changes.
