Whole house fans not only make houses and buildings more comfortable, they also safeguard your health by providing ventilation, cooling, and fresh air. Most houses are designed to be heated and cooled through a central heat and air system. They’re built to be airtight, with fresh air entering only through a mechanized system or by accident. Open windows and doors, cracks, leaks, and holes are responsible for most of the fresh outdoor air building occupants breathe when HVAC systems are in use. Stale air could very well be the culprit for a number of health complaints from homeowners, office workers,...

A whole house fan benefits building occupants by cooling a structure and exhausting stale air. It can be used in conjunction with A/C to reduce cooling costs, or alone in less humid regions of the country to create a more natural way to beat the heat. At just a fraction of the cost of A/C ($150 to $350 vs. $2,000 to $4,000), whole house fans can run at .01 to .05 cents per hour. Compare that to the .20 to .25 cents per hour it takes to cool with A/C. Whole house fans work best when used at night, when...

We all want to make more money and spend less for certain luxuries. This includes our ability to remain warm when it’s cold outside and cool when it’s hot outside, and evaporative cooling systems offers the solution for all of it. With the ability to keep a home cool as economically and energy efficient as possible, it’s well worth the time to learn about. Evaporative cooling systems are able to nearly always maintain a temperature below 80 degrees F. Many systems are capable of lowering temperatures within a home by as much as 30 degrees. This is significant and allows...

In today’s economy, evaporative cooling systems can offer savings for both residential and commercial ventilation needs. Evaporative cooling works by drawing warm air through a special filter that absorbs moisture from the air. Warm air is replaced by fresh outdoor air and recirculated through a home or building. Evaporative coolers work best in environments where temperatures are high but humidity is low. An evaporative cooling system can reduce the temperature in a home, office, or industrial facility by as much as 30 degrees, offering a level of comfort comparable to air conditioning. It can operate on half to three-quarters the...

The array of options on the market for residential, commercial, and industrial evaporative air coolers can be overwhelming. Homeowners, business owners, and contractors should ask a few questions before choosing an evaporative cooling system: How much space needs to be cooled to maintain comfort and productivity? What type of system best meets the needs of the building? Are there large, expansive spaces or several smaller rooms? Is there existing ductwork or will ductwork be installed? There are units designed specifically for use with existing ductwork. What is the layout of the existing ductwork? Certain units may operate efficiently with current...
