The Frequency Of Air Duct Cleaning

Your home’s air ducts serve as conduits for warm and cooling airflow.

When was the last time you considered the cleanliness of your air ducts? Most individuals assume their ducts are clean enough and never give them a second thought. But with time, your ducts begin to gather debris, insects, and even vermin like rats and mould in addition to dust. In addition to just being blown into your home every time your HVAC system is turned on, these substances can begin to clog up your vents, decreasing their effectiveness. This implies that the cost of cooling or heating your building will increase.

Every home must have HVAC (heating, ventilation, and air conditioning) systems. This system is in charge of heating and cooling your house so that you can live comfortably throughout the year. There are many different types of HVAC systems available, and each has unique maintenance requirements.

Regular air vent cleaning is a crucial component of appropriate maintenance for all other types of HVAC systems, barring ductless HVAC (also known as ductless mini-split systems).

Everything you need to know about cleaning air vents, including how frequently you should do it, will be covered in this article. We’ll go over the basics of what air vents are and why they need to be cleaned frequently to safeguard your home and health.

When you Need Your Ducts Cleaned?

When should your ducts be cleaned? Both new and experienced homeowners are faced with that query. When moving into a new home, a cleaning should be performed, especially if the previous owner smoked, kept pets, or neglected to service the ducts within the preceding three years.

⇒ A musty odour or visible mould

Mold adores humid, moist, inaccessible locations like your air ducts. A cleaning of the contaminated ductwork should be performed if you can physically see mould, smell mustiness in the air, or experience symptoms like itching or coughing. A reputable service provider can remove the mould by sterilising the area to stop any further growth and contribute to its future prevention.

⇒ Infestation of pests

The air that is circulated throughout the house might get contaminated by the trash and stink left behind by creepy crawlers who establish a home in your ducts. A thorough cleaning can get rid of vermin and keep them from pestering you again if you discover pests in or around the ductwork or notice a drop in your system’s function.

Another justification for cleaning air ducts is that they can accumulate over time with dust, pet dander, dead skin cells, and potentially harmful allergens.

Buildup reduces air flow and performance while putting you and your family at risk for respiratory and other health problems.

According to the NADCA, “the U.S. Department of Energy estimates that between 25 and 40 percent of the energy used to heat or cool a home is wasted.” This could shorten the system’s lifespan and hurt your pocketbook. How can the airflow in air ducts be increased in light of this?

  1. Shut off the HVAC unit.

  1. To properly clean the slats and grilles, use a brush. Use soap and water if you notice any dirt on these.
