More Heat on the way?


The weatherman says we're in for more unusually warm summer days, and we also have the smoky air to contend with. Insight Home Inspections suggests a variety of ways to keep your cool at home.
Ceiling fans circulate the air within the room which make the room feel cooler. They are very heavy - if you're installing one of these, please make sure that you install it with the mounting box that comes with the fan.
Whole house fans (sometimes called attic fans) are simple to maintain and inexpensive to run, compared to air conditioning. They push large amounts of air out of the home. To avoid pressure building up in the attic, there must be sufficient attic ventilation to allow equal amounts of air to leave.
Evaporative coolers pull outside air into its cabinet and through pads saturated with water which cools the air and distributes it through the home. These are more frequently used in areas where humidity is low. Keeping the system clean is very important.
Central air conditioning systems are very complex. They compress refrigerant gas into a liquid. A valve expands the liquid back into a gas which absorbs heat from a passing air stream. Finally a blower circulates the cool air throughout the home. Window air conditioners use the same process but does not go through ducting to different areas of the house.
...and then there's the Bay Area's favorite solution. Open your windows, and let cross ventilation do the job.
