The Pasadena area has recently been at risk of wildfires as temperatures reached the high 80s and 90s. Even though meteorologists predicted thunderstorms, experts were still worried that lightning would strike dry land and set off blazes that would spread rapidly because of high winds and dry patches. In addition to the risk of fires, Pasadena, California air conditioning contractors also say heatstroke and other heat-related illnesses are a potential threat. They recommend changing A/C filters monthly and maintaining air ducts in order to retain efficiency and prevent malfunctioning. In addition, A/C and heating contractors in Pasadena say residents should avoid the heat at all costs, and if they don’t have a functioning air conditioner they should relocate to malls, movie theaters or other public, cooled locations.
