The winters in our local area are extremely frigid and snowy. They tend to last for anywhere from several to several weeks, creating a sizable workload for the furnace. While both of us only get summer-like weather for approximately more than two weeks, the heat and humidity can be brutal. It seems care about the afternoon after I shut down the furnace, it’s necessary to start up the air conditioner. However, the heating and cooling unit share demands. The HVAC duct operates just about non stop. The system of pipes is responsible for delivering and removing air from the various rooms of the house. Any buildup of contaminants inside the duct system restricts airflow and forces the furnace and air conditioner to run longer and toil harder. This diminishes efficiency, increases utility bills and adds to wear and tear on all components. Because the ducts are hidden behind walls and ceilings, they are not easy to access. Service requires specialized equipment. After reading an article on the importance and impact of the duct system, I decided to hire an HVAC contractor to inspect, test and potentially disinfect the ventilation system. The professional found an frightening amount of pollutants concealed inside the pipes. There was dust, pollen, lint, dander, webs, insects. mold and even a dead rodent. Every time the furnace or air conditioner was operating, there was the potential for these harmful toxins to become airborne and get spread throughout the house. The air our family breathes was most likely a health risk. The cleaning process was completed in a couple of hours by way of a machine that resembled an oversized vacuum cleaner. The professional used a long hose with a brush attachment to dishome stubborn debris and effectively detach it.
