Improving Your Home Comfort by Enhancing the Air 

The perfect answer to indoor air quality problems?

from escaping, it can create uncomfortable living conditions. That’s because the same air is continuously circulated throughout the home. A lack of fresh air can make the air feel heavy and overly warm. It can also lead to humidity imbalances and put homes at risk for damage from mold. 

To ensure proper air circulation and quality, the average home should have at least .35 ACH (air changes per hour). Many newer, tightly sealed homes have an ACH rating as low as .05, which can lead to an uncomfortable and unhealthy buildup of moisture and pollutants.

Solution: Dehumidification (removing moisture) 
If the air in your home feels muggy, you may have a problem with humidity. 
Other telltale signs include: 
     Flaking paint  
     Peeling wallpaper 
     Condensation on windows 
     Damp spots or stains on walls and ceilings 
     Damaged or rotted wood materials  
     Musty smells 
     Insect infestation 

The Humiditrol® whole-home dehumidification system works with your central  heating and cooling system* to manage moisture levels, so you can enjoy greater  comfort. And dry air feels cooler, so you may be able to set your thermostat higher  and save money, and be more comfortable at the same time. 

If you’re like most people, you may try to cope with high humidity by lowering your thermostat while your air conditioner is running. But this can increase your utility bills and make your home feel too cold, rather than comfortable.

*Designed for integration with a two-stage air conditioner with R410A refrigerant, variable speed  air handler and ComfortSense™ 7000 Series Touchscreen Thermostat. 

Solutions: Humidification (adding moisture) 
Healthy Climate® humidifiers, working together with your central comfort  system, help maintain just the right moisture levels. With three capacities and  two control options, you can trust Healthy Climate humidifiers to provide the  right solution for your home’s needs. 

Power Humidifier  
Equipped with a built-in fan, a flow-through or power humidifier circulates humidified air throughout your home via your furnace duct system. 

Bypass Humidifier 
This system uses a damper (similar to a valve) to control and direct humidified air to each room in your home.

Solution: Fresh-air ventilation
Healthy Climate ventilation systems replace stagnant indoor air with cleaner air  from outside. They offer the fresh-air feel of an open window, with little or no  loss of heat or energy. 
Energy-Recovery Ventilator (ERV)  
Ideal for high-humidity climates, an ERV draws stale, moisture-laden air from inside the house and vents it outside, replacing it with an equal amount of fresh air. 
Heat-Recovery Ventilator (HRV) 
Also known as air-to-air heat exchangers, HRVs are similar to ERVs, but are designed for cooler climates. They retain heat from indoor air and transfer it to the airstream coming from outside.

Why should you keep your home’s air clean? 


Poor air quality can lead to poor health. 

Pollutants in your home’s air can cause dizziness, headaches, nasal congestion and  fatigue, and they can aggravate allergies and asthma. 

Plus, it can affect how you feel. 

Humidity inside your home has the same impact on your comfort as humidity outside.  Too much moisture can make you feel sluggish, weak and even sick. Too little can leave  you feeling cold and achy. 

The flow of air is also a factor. If it isn’t moving freely from room to room, your home  can feel stuffy or stale. This also causes unpleasant odors to linger.





High Humidity
(Relative humidity levels above 50%*)

High levels of humidity can make your home feel warmer than the actual temperature and create a breeding ground for mold, mildew, dust mites and bacteria.

Dehumidification – Dehumidifier systems remove moisture from sticky indoor air, making you feel more comfortable— without having to turn down your air conditioner thermostat and over-cool your home.

Low Humidity
(Relative humidity levels below 35%*)

Dry air can cause skin irritation and respiratory** problems, not to mention annoying static shocks.

Humidification – Humidifiers add moisture to the air, making it easier to breathe—in every room of your home.

Stale or Stagnant Air

Poor ventilation can make rooms feel stuffy. This is a common problem in newer homes, which are tightly sealed to conserve energy. This also means contaminants have no way to escape.

Ventilation – Ventilation systems replace stale indoor air with fresh air from outside.

 *National studies indicate that, for optimal comfort and health, your home’s relative humidity levels should range between 35  and 50 percent. 
**Exposure to excessively dry air (relative humidity of less than 20%) can cause respiratory irritation.  Source: American Academy of Allergy, Asthma and Immunology.
