For residents of Southern Maryland, the arrival of spring often brings the joy of blooming flowers and warmer weather. However, it also marks a crucial time to consider something often invisible but vital to our well-being: the air we breathe. Simmons Heating and Air Conditioning Company is proud to highlight Air Quality Awareness Week, taking place from April 28th to May 4th, and to emphasize the importance of clean indoor air for your home and health. Air Quality Awareness Week, organized annually by the U.S. Environmental Protection Agency (EPA), aims to educate the public about the impact of air pollution on our health and the steps we can take to improve air quality, both indoors and outdoors.
