Do New Furnaces Smell

Problem Of Noticeable Odors When Installing A New Furnace

A new furnace can be exciting. But when it starts giving off strange smells, it can be alarming. This is because the chemicals and cleaning products used during manufacture are burning off. This smell is normal and usually goes away after a few days.

Not all odors are harmless though. If you smell gas or oil, there could be a serious problem. In this case, switch off your furnace and call an expert.

To avoid any odor issues, get qualified professionals to help. They’ll pick the right furnace for your home and install it correctly.

So, don’t blame your spouse for the ‘rotten egg’ smell. It could be your furnace trying to be funny!

Different types of odors

Furnaces can let off various odors like burning smell, egg smell, musty odor, and rotten egg smell. These smells can signify problems with your furnace. Below are six tips to know concerning these odors:

  • Burning smell could mean filters or ducts need cleaning/replacing.

It’s best to be vigilant with furnaces. Knowing about the odors they can emit helps avoid any potential hazards. Regular maintenance can save you from disappointment and extend the life of your furnace!

Causes Of Furnace Smells

To investigate the causes of furnace smells with some possible solutions, let’s look into different scenarios that can lead to these issues. If your furnace is new, the smell could be attributed to the burning dust or protective oil coating. On the other hand, mold growth or water damage in the furnace or air ducts can be reasons why your house smells. It is important to be vigilant about gas leaks or carbon monoxide poisoning which can pose a serious threat to your family’s health and safety.

Burning dust and protective oil coating

As your furnace warms up, you may detect an odd scent. This could be due to either burning dust or oil coating. Dust can build-up when the furnace has been off for a while. When switched on, the dust will burn off – this should only last for a few hours.

Manufacturers sometimes coat heating coils with oil to prevent rusting during transit. When the furnace is used, the oil burns away – again, this should stop after a short time.

If neither of these are the cause, call a professional. It might be a wiring or motor problem. Preventative maintenance can help avoid this. Get a contractor to look at it if there’s any doubt – this can prevent health issues or fires.

If it smells like a wet dog, it is likely mold or water damage in the ducts.

Mold growth or water damage in the furnace or air ducts

Mold and water damage can cause yucky smells in your furnace or air ducts. These problems are usually from too much moisture, which provides the perfect place for mold to grow. If left alone, this can cause health issues for you and your family and can even make your furnace break down.

It’s best to get help from an expert HVAC technician right away. They will check for mold growth and water damage and fix it. To avoid these problems in the future, think about getting a dehumidifier or having regular duct cleaning done.

The Environmental Protection Agency warns that indoor mold can cause breathing issues and make allergies worse. If you think you may have mold in your HVAC system, take quick action.

Who knew that a furnace could be so dangerous? Gas leaks and carbon monoxide are odorless, but the effects can be lethal.
