A heating, ventilation and air conditioning system (HVAC) is more than just a furnace and air conditioner. The system as a whole can drastically improve your indoor air quality, and includes air purifiers, filters, air exchangers, humidifiers, dehumidifiers, UV lamps and even ductwork. According to the United States Environmental Protection Agency (EPA), Americans are spending approximately 90 percent of their time indoors, where the levels of pollutants may be two to five times — and occasionally more than 100 times — higher than outdoor levels. What’s more is the American Lung Association says poor indoor air quality can cause or contribute to the development of bacteria, viruses, cancer and lung diseases. Here at Haley Comfort Systems we are committed to helping you improve your indoor air quality, which can lead to utility savings, but more importantly, to long-term health benefits for you and your loved ones.
