Controlling Humidity

Your home comfort system should provide both comfortable temperatures and comfortable humidity levels.

It is recommended that indoor humidity be managed to be in the 40-60% range.

Humidity System

• A system with variable speed blower
• A thermostat with humidity control

Air Filters

Air filters protect you and your family by removing pollutants that are harmful to your health.

Improved Air Quality
The quality of your indoor air can be improved significantly by adding an air filter to your heating and cooling system.

Air Pollutants

Chart: Size Comparison of Pollutants in Microns*

*This chart is intended to provide information on particle size only, not air cleaner performance.

99% of the particles in the air are not visible to the naked eye. These are the particles that are most dangerous to your health:

• Aggravating allergies and asthma
• Contributing to colds and flu

A standard one-inch filter captures less than 5% of the particles in the air. This leaves the other 95% to:

• Pollute indoor air
• Contaminate duct work
• Reduce the efficiency of your heating/cooling equipment

Ventilator Benefits

• Odor dilution
• Introduction of fresh, outside air
• Reduces energy loss to a minimum

Noise Level: Outdoor Unit

The quietest OUTDOOR units have two speeds (high and low) and run on low speed about 80% of the time with longer run cycles for dramatically reduced sound levels and less on/off disturbance.

Noise Level: Indoor Unit

The quietest INDOOR units have a variable speed motor and run on low speed about 80-90% of the time for whisper quiet operation. They also have longer run cycles and gradual ramping up/down for less on/off disturbance.

Advantages

Systems with variable speed blower motors have significant advantages over single speed systems.

• Reduced room temperature fluctuation
• Better humidity control
• Quieter operation due to motor ramping up and down slowly vs on/off

• Air cleaners only filter the air when the blower is on - variable speed can run continuously for just pennies a day

• Lower energy bills
• Improves system heating & cooling performance
• Energy Star rated
