best time of year to clean air ducts

Since air ducts have a big part to play in keeping you healthy and your home clean, you need to clean them regularly. But cleaning these ducts can’t be done without any detailed planning, as it consumes a lot of time and needs a lot of effort.

A big part of this planning phase is to choose the best time of year to clean air ducts.

Two seasons are better for cleaning your air ducts, spring, and fall. If you clean your ducts in spring, you can clean off all the dust and debris accumulated in the ducts, while also keeping your home healthy. On the other hand, if duct cleaning is done in the fall, you can remove mold and increase the efficiency of the HVAC units. 

Let’s take a detailed look at when you should clean your air ducts. 

When should I clean my air ducts?

Air ducts filter out the dust, dirt, and other allergens in the air inside your home to make it clean. These ducts also play a big role in making your home comfortable and energy efficient by taking the air to HVAC units to cool/warm it. But if left unclean, these ducts can create serious issues, such as mold-caused allergies, and energy inefficiency.

This is why you should clean your air ducts often, and plan accordingly. While planning for air duct cleaning, you must keep a few important factors in mind, such as the best time to get ducts cleaned.

You can choose between spring and fall to clean your air ducts, both of which have a few advantages. So, when is the best time to clean air ducts? Take a look and make up your mind. 

When should you get your air ducts cleaned: Spring

Spring is a great candidate for the best season to clean air ducts. Once the need to use the HVAC units after winter becomes minimal, you can start cleaning your air ducts. Here are why you should clean your ducts in the spring. 

Cleanliness: During winter, the air is dry and there is a lot of dust swirling around in it due to the lack of moisture. Also, people spend more time at home than in any other season, causing them to make their homes dirtier than usual. Finally, pets shed their winter coats during spring, which fills the home with hair. 

For all these reasons, you should clean your air ducts during spring. Doing so will allow you to make your home as clean as possible, as it will clean up every bit of dirt and debris accumulated in the ducts. 

Health: Cleaning all the dirt and dust from your air ducts also improves the health conditions of the inhabitants of your home. Dust and pet hair can cause health issues such as allergies in people living in a house. Cleaning the air ducts in spring will solve this problem. 

Getting rid of pests: During winter, the air ducts circulate warm air in the home, which attracts animals such as rodents and insects. They climb inside the air ducts to save themselves from the cold outside but never leave after the season ends. This creates a lot of issues for the inhabitants, such as foul smells, etc. 

When you clean the air ducts in the spring, you can get rid of all the pests from your ducts, and clean up the mess they have created. 

When to do duct cleaning: Fall

Fall is yet another good option for you to clean your air ducts. Cleaning ducts during fall will mean you can be ready for the upcoming winter. Here are the main reasons why you should clean your air ducts in the fall. 

  • Removing mold: Mold needs dark, and moist conditions to grow and proliferate. As the temperature drops in fall, and the ducts are dark, they can grow and spread very quickly. This can cause various health issues, especially allergies in elderly people. Cleaning the air ducts in the fall will allow you to get rid of mold as soon as possible. 
  • Improving the HVAC units’ efficiency: Clogged air ducts can seriously harm the efficiency of your home’s HVAC units, as they have to work harder to warm/cool the same amount of air. As winter approaches, you have to use your HVAC units even more, so making sure they work fine is mandatory. 

Cleaning the air ducts in spring means the HVAC units don’t have to work very hard, which will not only save them from wearing out too quickly but also ensure your home will be energy efficient. 

Final Thought

The best time of the year to clean air ducts is the one that suits your requirements the most. If you have pets, and there is a lot of dust in your area, you should clean your air ducts in the spring.

On the other hand, if your HVAC units are not efficient, and you fear that mold will grow in the ducts, then clean them in the fall.
