For your HVAC system to operate at its optimum efficiency and deliver high-quality air throughout your home, you should regularly have your air ducts cleaned. Unfortunately, indoor air pollution can be up to five times more harmful than outdoor air. These impurities can accumulate inside the ducts, causing them to recirculate and trap the toxins. This can be detrimental to the health of your entire family.

Every three to five years

If you are a homeowner, you have probably wondered how often you should have your air ducts cleaned. The answer depends on your situation. Depending on the pollutants in your home’s air, it could be a year or a month. Even if you have a brand new home, it might need to be serviced more frequently. A professional air duct cleaning should be done at least once every three to five years to ensure good air quality.

The EPA and NADCA warn that the air we breathe is more polluted indoors than outdoor air. Because air ducts recirculate pollutants from outside, they can harm your home and your family. Professional air duct cleaning from a licensed HVAC contractor is essential, but you may need to have them cleaned more often in exceptional circumstances. For example, if you move into a new home, you should have the air ducts cleaned as soon as possible. If the previous owner of your home smoked, this should be your priority.

Every two or three months

The term “every two or three months” is a little confusing. This period occurs every two months but isn’t as long as the term semimonthly. When used with an object, it implies that the item is replaced every two or three months. In some contexts, bimonthly, trimonthly, and twice-monthly mean the same thing. If you’re unsure about the correct usage, spell out the term for clarity or use different words. Semimonthly is a ubiquitous term in the US, but it is not used in other parts of the world.

While bi-monthly refers to monthly intervals, biweekly indicates every two weeks, and bimonthly means once or twice a month. However, it’s not a good idea to use bi-monthly for two-monthly intervals. You can get confused using it with a semimonthly break or monthly, but it’s still wrong. The word bi-monthly has two correct definitions: twice per year or bi-monthly.

Every two or three years

Many writers work for a living by writing one show every two or three years. Artists like Justin Timberlake, whose albums sell out arenas yearly, make the same journey over several years. Some writers even plan their entire career around a single show. These artists are known as “giants” of their genre. They meet every two or three years and will probably make this same journey for the rest of their lives.
