Does duct cleaning actually work?
Given normal accumulation of dust in all homes with air ducts, there are several other factors that can cause the need for regular air duct system cleaning such as, pets, cigar or cigarette smoke, renovation projects, water damage to the home, and even occupants with allergies.
There are instances when some occupants are more sensitive to the duct system contaminants than others. Indoor air quality is an important factor to take into consideration when having allergies. The process of air duct cleaning can help improve indoor air quality by removing contaminants from the duct system.
Benefits of HVAC duct cleaning
If something looks dirty majority of the time it is dirty, that’s why it is important to call a licensed HVAC professional if your air ducts look dirty. The following information has some reasons homeowners/business owners choose to have their air ducts cleaned.
Indoor air quality
Simple every day activities bring contaminants and particulate into a home or business. These contaminants are pulled into the HVAC system through the return air vents and then distributed throughout the duct system and into the home or business. Over time, this re-circulation causes buildup of dust and debris in the duct work.
A concern that leads individuals to educate themselves on air duct cleaning is Indoor air quality. The HVAC system takes the air inside the home or business to cool or heat it and re distribute the air to the home to ensure the climate is the temperature desired by the thermostat operator.
Dirty ducts do not necessarily mean you have polluted air in your home, business or workplace. The dust that accumulated on the inner walls of the duct system can be pulled through the evaporator coil and choke the system but not allowing the proper amount of air to be pulled through the system. This normally leads to much bigger problems which also affect indoor air quality.
Does duct cleaning really save on energy?
According to the U.S. Department of Energy, 25 to 40 percent of the energy used for heating or cooling a home is wasted. When the heating and cooling system cannot breathe properly it is forced to work harder which can shorten the life of the system. By cleaning the HVAC system, you can ensure the system doesn’t have to work as hard to maintain the desired temperature inside of the home or business. When the HVAC unit is operating efficiently, the energy consumption is reduced. Regularly changing the return air filters can help the unit breath better as well. Regardless of the frequency the filters are changed, the system will still collect deposits of dust and debris inside the ductwork and require cleaning over time.
