According to the U.S. Department of Energy, 25-40% of the energy used for heating or cooling is wasted. Contaminants in the HVAC system cause it to work harder and shorten the life of your system. Although filters are used, the HVAC system can still get dirty through everyday use.
When the HVAC system is clean, it doesn’t have to work as hard to maintain your desired temperature. As a result, less energy is used leading to cost-effectiveness and a lower electric bill!
Indoor air quality is one concern that every homeowner has when they decide to investigate air duct cleaning. In a typical 6 room home, up to 40lbs of dust is created each year just through everyday living. Your HVAC system breaths this air in and puts it back out. A typical home generates a lot of contaminants and air pollutants, such as dander, dust, and chemicals. These contaminants are pulled into your HVAC system and recirculated 5-7 a day on average. Over time, this recirculation causes a build-up of contaminants in the ductwork.
While dirty ducts don’t always mean unhealthy air in your house, school, or workplace, they may be contributing to larger health problems or harboring contaminants that could cause serious problems for people with respiratory health conditions, auto-immune disorders, or some environmental allergies.
We use a duct cleaning machine that has HEPA filters and feed an agitation tool down every vent in the house. We will show you the results of before and after of what we found. Many people with allergies notice an immediate impact.
You should be aware that although a substance may look like mold, a positive determination of whether it is mold or not can be made only by an expert and may require laboratory analysis for final confirmation. For about $50, some microbiology laboratories can tell you whether a sample sent to them on a clear strip of sticky household tape is mold or simply a substance that resembles it.
