Benefits of HVAC Cleaning

NADCA’s general rule of thumb for homeowners is simple: if your air ducts look dirty, they probably are. When there are visible signs of buildup or concerns about system cleanliness, the HVAC system should be evaluated by a reputable NADCA member company that follows established industry standards for inspection and cleaning.

Below are some of the common 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 alone don’t define indoor air quality, they can add to conditions that affect health in homes, schools, and workplaces. 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. 

Energy Savings

According to the U.S. Department of Energy, 25% to 40% 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. Proper HVAC system cleaning helps systems 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.
