John’s knows the air pollution facts Phoenix!
Air pollution is caused by both human and natural sources. Human sources include vehicle emissions, agriculture, and industry. Natural sources include volcanic eruptions, emissions from vegetation, and dust storms, which are a big part of our monsoons here in the Phoenix area.
Air pollution is worse in the winter as opposed to the summer because of all the coal and wood burning used to heat our homes. During the winter, a layer of cooler air is trapped by a layer of warmer air above, forming a temperature inversion. An inversion traps pollutants close to the ground, increasing the chances for harmful particulates to reach unhealthy levels.
At night, the ground level temperature cools faster than the air above it, trapping pollutants under the layer of warm air. The warm air above the cooler air acts like a lid, trapping the cooler air at the Mediasurface, keeping pollutants near the ground, and leading to poor air quality. As the sun rises, the ground level temperature warms up faster than the air above it, pushing the air upwards, breaking up the warm air layer and allowing the pollutants to escape.
The strong inversion in winter confines pollutants to a shallow vertical layer, leading to high (poor) air quality levels. This is why “no-burn days” in the Valley of the Sun are issued: so the use of woodstoves and fireplaces don’t add to pollution conditions during the winter.
Outdoor air pollution contributes to indoor air quality, with both affecting our health. When your home is closed up – in summer as well as in winter – it can seal these pollutants in where you and your family spend most of your time. A clean HVAC system is crucial to your family’s health and the air quality inside your home. John’s Refrigeration Heating and Cooling can evaluate your duct system to determine if the bad air outside is entering your home and will recommend actions you can take to keep the air inside your house as clean as possible.
