Summertime in Hawaii means that homeowners from Hawaii Kai to Ewa scramble to find ways to cool their homes without running up their energy bills. Some resign themselves to spending hundreds more in higher electricity bills that come from running air conditioning. Others will use an assortment of tricks to try and beat the heat.
“My dad cut a hole in the wall of his attic to try to draw heat out with a box fan,” said Lani Abrigana of Ewa Beach. “Dad was always a tinkerer. Unfortunately, it wasn’t strong enough and didn’t end up working.” Fortunately, Lani is one of hundreds of Oahu homeowners who have benefited by installing an alternative cooling system, the whole house fan.
Unseen from the outside of the home, the whole house fan quietly draws hot air out of the living space through a ceiling in-take while cooling both the home’s living space and attic at a fraction of the cost of air conditioning systems and without a hole in the roof.
Lani’s whole house fan system is comprised of four bedroom units in her home, which were installed along with reflective insulation from Island Cooling. Lani said, “I was at work when it was installed, but when I stepped into the home afterwards I noticed an immediate difference in temperature.” She continued, “Ewa is hot during the day, but the reflective insulation kept the heat out of the home until the air cooled down. When the whole house fans were switched on, I had a cool breeze being drawn into the bedrooms from the fairways. My system has worked so well!”
