Both residential and commercial consumers demand more energy-efficient homes and workplaces. While "tighter" buildings minimize heat loss and save energy, they can also trap indoor air pollutants. Odors and gases can build up. Microscopic contaminants continue to circulate through the comfort system.

Carrier has pioneered a broader definition of comfort with ventilation and air handling systems that provide circulating, "open-window" fresh air without wasting previous heating or cooling energy. We have developed a new air handler for commercial applications that helps eliminate water buildup that can breed molds and bacteria. Our Heat Recovery Ventilator exchanges stale indoor air for fresh, healthier outdoor air up to eight times a day. Our electronic air cleaners remove most airborne dust, dirt and pollen, as well as significant amounts of bacteria, molds and other contaminants.

Carrier Corporation puts premium on air quality — including proper humidity.

Willis Carrier invented air conditioning almost a century ago when, instead of merely drawing air over ice or through falling water to cool it, he found a way to control humidity along with temperature. And today, Carrier Corporation is the only manufacturer who makes everything a homeowner needs to heat, cool, clean, humidify, freshen and distribute Custom Made Indoor Weather to every corner of any home all year long. And only Carrier does it all so efficiently.
