Strange Smells From The Heating Vents?

Lori Harris

When the cooler months take over and you turn on the heat for the first time in a while, it's not strange for the smell of burnt dust or some other harmless material to fill the air. If the smell persists for weeks on end or has a particularly irritating feel to it, you may need to take a closer look and get the help of a professional, such as Arlington Heating & Air Conditioning. Take a look at the legitimate reasons for burning smells in heating and air conditioning systems, then the dangers that could betray bigger problems.

Dust And Debris Over Time

When the heating portion of an air conditioning and heating system is dormant, dust builds up. The heating unit and the connecting ductwork traps in any dust that enters the ventilation shafts, which can be anything from dust and dirt kicks across the floor as people walk by to naturally settling dust.

As you turn on the heat for the first time, the dust clinging to the heating unit begins to burn. Although unpleasant, the burning and accompanying smell shouldn't last for more than a few days. If you don't turn on the heat often, you may be dealing with the smell every time you turn on the unit for a few hours, but this is simply because the dust is allowed to build up again.

A problem exists if you're dealing with weeks or months of bad smells from the ventilation. There could be a lot of caked up dust, mold, grime, chemicals, insects or even small pests that are burning near the heating unit. Unfortunately, most homes lack the working area for non-professionals to clean out the ventilation. 

Many homes are equipped with a small access compartment that requires crawling on hands and knees to access, which means you'll need to know your way around a heating, ventilation and air conditioning (HVAC) system in the low light of a flashlight.

Some buildings may have ductwork in the basement, but taking the ductwork off can be challenging. Reinstalling ductwork incorrectly could lead to more debris getting in, so consider getting a professional's assistance.

A Professional's Analysis For Better Performance

With a professional's help, the ductwork can be examined for dust and other debris, and there may even be a better way to arrange your ventilation system to avoid buildup. If it's a simple issue of not having regular maintenance, air conditioning service professionals can handle your air conditioning and heating systems all year long.

Regularly scheduled maintenance as the seasons change and emergency calls when something breaks down can happen much faster, since you won't have to flip through advertisements every time something different breaks. If you want an upgrade, the HVAC professional can suggest climate control options and give ductwork advice that can manage your home better.

Contact an air conditioning service and repair professional to discuss maintenance and other causes of strange smells from the vents.
