You want your home to be a safe haven for your family. The place where you eat, sleep and breathe should be free from hazards and truly protected. Part of maintaining a safe home environment involves making sure that you and your family breathe the cleanest air possible.

What is Indoor Air Quality?

When most people think of ‘air’ quality, they think of the air outside and the U.S. EPA’s pollution index.  Even though most people are aware of the effects that poor ‘outdoor’ air quality can have on a person’s health because our local news agencies often report our local ‘outside’ air quality, people are in many cases unaware of the greater concern of ‘indoor’ air quality. The American Lung Association, EPA and other health related organizations are actually quite concerned with the quality of the air we breathe indoors. People are spending ever increasing amounts of time in their homes and in buildings. This fact is driving the need for greater awareness of indoor air quality because indoor air quality is having an increased, measurable effect on people.  Indoor air quality, commonly abbreviated as IAQ, is simply the measured quality of the air people breathe while inside homes and buildings.  Indoor environments are often filled with thousands of different pollutants with varying degrees of irritation to respiratory systems that contribute to various ailments. In fact, several Environmental Protection Agency studies of human exposure to air pollutants indicate that indoor levels of pollutants can be considered to be 2 to 5 times higher in general, and in the extreme, can be more than 100 times higher than outdoor levels.  These numbers become more alarming when you factor in that the EPA has estimated that the average person today in America spends approximately 90% of their time indoors. 

Good indoor air quality is a healthy indoor environment where the air quality in the enclosed environment supports robust respiratory function promoting healthy physical and mental functionality allowing for high levels of productivity, restful sleep, natural respiratory comfort, a sense of well being and supporting overall good health.

Heat Recovery Ventilators in Silicon Valley

Some of the highly energy-efficient homes constructed in Silicon Valley in the 1970s were so airtight that they developed indoor air quality issues. In an effort to achieve higher levels of energy efficiency, stale air, odors and moisture couldn't exit the home, and fresh air wasn't entering.

After a while, your heating and cooling system's air ducts can get clogged with excessive amounts of dust and debris that are released into the home, and they can get also get infested with rodents or insects.

Based on Yelp reviews, I called Residential Heating and AC to do an inspection of our ducts, as well as check operation of our furnace. Jim S. responded to our call and was right on time! He is a nice, efficient, knowledgeable guy to work with. He detected that some wires had not been correctly connected when the unit was installed by another company. Within 1.5 hours, the unit was cleaned, inspected and repaired. I was expecting a bill big enough to fund a war – as well as a negative verdict.
