HVAC air ducts carry air from your HVAC system to your space. When the HVAC air ducts are dirty, you’ll have to face problems like poor indoor air quality, unflattering odor, and sometimes HVAC system failure. As these problems can compromise your overall comfort, it’s important to clean your HVAC air ducts when it’s needed.


When Should You Clean the HVAC Air Duct?

There is no definite answer to this question because several factors affect HVAC air duct’s cleanliness. For example, if you have recently bought your air conditioner and it’s well-maintained, chances are your HVAC air duct is in good condition. In this case, you can delay the HVAC air duct cleaning for a bit.

But if your HVAC system is relatively old or it’s being used for industrial purposes, chances are you may need an HVAC air duct cleaning service. As industrial or commercial areas are full of dust and other contaminants, these accumulate in your heating and cooling system. And thus, your HVAC air duct gets dirty.

There are a few symptoms that will help you know whether you need HVAC air duct cleaning or not.

1.      Humidity Problem

If you’re facing any humidity-related problems, like lack of humidity in air or excessive humidity in your home, chances are your HVAC air duct is clogged and requires cleaning.

When the HVAC air duct is clogged, it won’t be able to release the produced air to your space. As a result, you won’t get your desired temperature, and you’ll have a more humidity-related problem. However, there can be several other reasons behind such problems like low refrigeration level, dirty HVAC air filter, etc.

That’s why if you feel that you’re sweating more or feeling uncomfortable in your home or office space, it’s better to call an HVAC professional and check your system thoroughly. This will prevent you from hefty heating and cooling repair fees.

2.      Bad Odor

Over time, due to lack of heating and cooling maintenance, molds and other microorganisms can build up in your HVAC system and cause bad odor problems in your area. When there are molds and other microorganisms in your HVAC air duct, you’ll notice lingering or bad odors coming out of your heating and cooling system.

To solve this problem, you’ll have to call an HVAC professional or air duct cleaning company and fix the problem as soon as possible. Because when there are molds in your HVAC air duct, it’ll reduce the air quality in your space drastically. Besides, these molds and bacteria cause various illnesses as well.

3.      Dust in the Register

When you don’t clean your air duct for a long time, dust and debris will start to accumulate in the air duct’s wall. If you notice that dust is coming out of your heating and cooling register, there is a high possibility that your air duct is clogged with dust and needs a quick cleaning.

How to Hire the Best HVAC Air Duct Cleaning Company?

It’s safe to admit that all HVAC air duct cleaning companies don’t offer the same quality cleaning service. If you have an unprofessional air duct cleaning service, your problem won’t be resolved. That’s why you’ll have to choose an air duct cleaning company that knows how to deal with an HVAC system and clean the air ducts.

1.       Check NADCA Certification

The first thing you’ll have to check before hiring an air duct cleaning company is the NADCA certification. NADCA or National Duct Cleaners Association has set up a few standards that every certified NADCA member will have to follow.

These certified HVAC air duct cleaning professionals maintain a rigorous standard for air duct cleaning processes and equipment. As a result, you get the best cleaning service for your HVAC air duct.

2.       Ask about the Mold Cleaning Process

After checking the NADCA certification, you’ll have to ask the duct cleaning company about the mold cleaning process. When a duct cleaning company has a definite cleaning process, it indicated that the company has enough duct cleaning experience and can handle your HVAC system.
