Air ducts, like any other air conditioning system, require regular cleaning to ensure maximum efficiency. The National Air Duct Cleaners Association (NADCA) recommends cleaning air ducts every three to five years. However, in some environments, the need to clean commercial air ducts is more immediate. There are a few factors that influence when it comes to setting how often you should clean your duct systems. Every 3 to 5 years is a standard recommendation, but you may want to consider doing it more often depending on certain factors.
The average duct system must be cleaned every two to five years. If your system is properly maintained and filters are changed twice a year, you can increase the time between professional cleanings. If your system has never been cleaned and has been active on your property for more than three years, it's probably due to a cleaning. Even a single station can accumulate enough dust and dirt in the system to make it less efficient than it was when it was first installed.
Changing air filters frequently is the best way to keep dust, allergens, and other particles out of your home. If you have a newly installed system or a system in a house you just moved into, check the filter once a month to determine how quickly it gets dirty at different times of the year. Most should be replaced every two to three months. It should also be noted that sharing your home with pets that lose hair will increase the amount of dust, dirt and hair inside the vents, requiring ducts to be cleaned more often. They will use industry-standard equipment designed to fit the size and volume of all types of homes, ensuring cleaner, healthier indoor air in your home.
A common statement from some air conditioning companies is that a home's air conditioning ducts should be cleaned at least once every three to five years to ensure that hair, dust and dirt don't affect the air quality of the house or cause health problems. And while the equipment and methods used by duct cleaning companies have changed since these studies were conducted, household air ducts haven't. So how often do air ducts need to be inspected and cleaned to maintain a high IAQ? How often you should schedule air duct cleaning depends on a few factors, but the National Duct Cleaners Association (NADCA) recommends cleaning your air ducts every 3 to 5 years. However, in large quantities, dust and dirt can pose a danger to air quality, so it is important to check the vents regularly and clean the ducts if an excessive amount of dirt enters the house through the exhaust vents.
Even if you use the system on a daily basis, if the air leaving the system smells strange, now is a good time to clean your ducts. While professional air duct cleaning may not seem necessary, you might be surprised at the level of expertise it requires. If your HVAC system requires more than just duct cleaning and requires repair or needs to be replaced, contact Direct Energy Home Services. In addition, studies on the effects of duct cleaning do not conclusively show that the presence of dust and dirt in ducts increases the levels of particles inside the house. The most likely culprits are the cooling system's evaporator coils, which your heating and air conditioning contractor and most duct cleaning companies can inspect and maintain.
While there are some benefits to cleaning and maintaining HVAC equipment, those benefits are relatively small, and little energy waste is attributed to dirt of the ducts or equipment. While the average cleaning service is very talented at cleaning surface level dirt, it's likely that they don't have the necessary skills to clean ductwork properly. Another vague statement made by most duct cleaning companies and their trade associations is that dirty ducts and equipment overload heating and cooling equipment, which it is a waste of energy.
