Benefits of HVAC Cleaning
NADCA’s rule of thumb for consumers is that “if your air ducts look dirty, they probably are,” and that dirty HVAC systems should be inspected by a reputable, certified HVAC professional. Below are some other reasons homeowners choose to have their air ducts cleaned.
Indoor Air Quality
Indoor air quality is one concern that homeowners have when they decide to investigate air duct cleaning. Your heating and cooling system is the lungs of your home. The system takes air in and breathes air out.
Through normal occupation in a home, we generate a great deal of contaminants and indoor air pollution, such as dander, dust, and chemicals. These contaminants are pulled into the HVAC system and re-circulated 5 to 7 times per day, on average. Over time, this re-circulation causes a build-up of contaminants in the ductwork.
While dirty ducts don’t necessarily mean unhealthy indoor air pollution in your home, school or workplace, they may be contributing to larger health issues. Dirty air ducts could be harboring contaminants that could cause serious problems for people with respiratory health conditions, autoimmune disorders or some environmental allergies. Having your HVAC system regularly cleaned can improve your indoor air quality.
According to the U.S. Department of Energy, 25 to 40 percent of the energy used for heating or cooling a home is wasted. Contaminants in the heating and cooling system cause it to work harder and shorten the life of your system. Although filters are used, the heating and cooling system still gets dirty through normal use. HVAC system cleaning may help systems to run more efficiently by removing debris from sensitive mechanical components.
When an HVAC system is clean, it doesn’t have to work as hard to maintain the temperature you desire. As a result, less energy is used, leading to improved cost-effectiveness. Clean HVAC systems are also less likely to break down and thus have a longer life span, saving you money in the long run.
According to the US Department of Energy, homeowners can cut their energy bill by as much as 20% to 30% by simply doing proper HVAC system maintenance, including air duct cleaning. Servicing your HVAC unit regularly (and also replacing filters each month) can go a long way toward optimal energy efficiency.
