The unexplained sweet smell in the house

You might be wondering what that sweet smell is. Is it a candle? A bakery down the street? Candy?

Nope, nope, and nope.

The source of that sweet smell is likely your air conditioner. When the weather starts to heat up, your air conditioner kicks into high gear and works overtime to keep your home cool. This process can create a strange, but not unpleasant, smell.

Don’t worry, though! The smell is temporary and will disappear as soon as your air conditioner takes a break.

What Is the Sweet Smell?

When there’s an unexplained sweet smell in your house, it can be difficult to track where it’s coming from. Sometimes, it might be easy to identify the source (like a bakery down the street), but often it takes more work to pinpoint.

It’s important to look for potential causes of this sweet smell because it could signify something serious. For instance, a gas leak might produce a sweet smell, like a faulty air conditioner or radiator. If you can’t find the source of the odor yourself, call in a professional to help you.

Common Sources of a Sweet Smell

There are a few common sources of a sweet smell in your house.

One possibility is that there’s a gas leak. Please leave the house and call the gas company if you smell gas. They’ll come and check it out and repair the leak.

Another possibility is that there’s a plumbing issue. If you smell sewage or something rotting, there’s probably a blockage in your pipes, and you’ll need to call a plumber to fix it.

And finally, there’s something sweet burning in your kitchen. Maybe you’re cooking something with sugar or syrup, or one of your appliances is malfunctioning. Whatever the case, it’s important to track down the source of the smell as soon as possible.

Troubleshooting to Eliminate the Smell

Now that you know more about the possible causes of this strange sweet smell, it’s time to troubleshoot. Here are a few things you can do to try to eliminate the odor:

  • Check your HVAC filter and replace it if it’s dirty
  • Clean your AC unit and coils
  • Replace your oven light bulb
  • Investigate any gas leaks in your home
  • Ensure that all of your plumbing is in good condition and properly sealed

Have a Professional Inspect Your HVAC Unit

If the sweet smell persists and you can still not pinpoint the source, it may be time to have a professional inspect your HVAC system and any other appliance that uses gas.

You can call an HVAC technician to inspect your vents, furnace, and ducts to ensure no leaks or faulty wiring. Also, check for mold or mildew since these can produce sulfur compounds that smell like honey or flowers. The technician may also determine if any of the appliances are releasing carbon monoxide, which is odorless but can be dangerous in high concentrations.

In addition, a professional exterminator could help you identify any pests in your walls that might be responsible for the sweet odor. While many of these critters produce odors much more unpleasant than sweet, some, such as honeybees, produce odors that smell pretty nice!

Other Potential Sources of the Smell

Have you checked all the obvious places, like your basement, attic, or laundry room? There could be a hidden leak in one of these areas that are causing the smell. You may have a pipe that has corroded and is releasing the sweet smell of natural gas. Remember to look for any signs of a slow water leak, as this can also give off a sweet smell.

You should also check any appliances or furniture in your home that use gas, such as a fireplace or stove. If there’s not enough ventilation, this can lead to an abundance of gas in your home and cause the smell. And lastly, don’t forget to check under all your sinks for any signs of leaking pipes— even small ones can release the sweet smell into your home.

If you’ve looked in all these places and haven’t been able to find the source of the smell, it may be time to call an expert who can help identify and fix the issue.

Preventative Measures for Avoiding Strange Smells

There are a few things you can do to prevent strange odors from appearing in your home. First, pay special attention to any leaks around the house. This includes washing machines, sinks, toilets, and showers, as a leaking pipe or drain can allow methane gas or another odor-producing substance to come in contact with your home’s air.

Additionally, check your garbage disposal and regularly inspect the filter for any sign of mold or blockage that could release bad odors into your home. It would help if you also double-checked any air vents that may be located near the kitchen or bathroom to make sure they are not blocked and can circulate fresh air throughout the home.

Finally, ensure you’re taking out the trash often and use proper odor-absorbing products like baking soda or charcoal powder. If all else fails, consult a certified HVAC and plumbing specialist for professional help finding and eliminating any strange odors in your home.


So what could be the source of this unexplained sweet smell? There are many potential sources, and it can be difficult to track down the exact cause. It’s important to do some detective work and rule out any potential sources of the smell.

If you can’t find the source of the smell, call in a professional to help track it down. A professional will have the equipment and expertise to find the start of the scent and solve the mystery.
