We install air conditioners to help us feel comfortable in our homes. But when you start to notice unpleasant odors coming from your cooling system, it’s more than just annoying. It can greatly impact your home comfort.

Where do the smells come from?

Start with what the odor smells like. If the odor resembles a rotten egg, this could be a sign of a gas leak. If this is the case, you should open your windows, turn off the gas supply, evacuate the home and reach out to the gas company. Be sure to have the gas company turn it back on for you. It’s not something you want to tackle yourself.

If it doesn’t smell like rotten eggs, you are likely experiencing a different issue.

Just like anything in your indoor space, if your air conditioner isn’t cleaned well or taken care of, there’s a good chance that dirt and dust will develop. And because components of your air conditioner aren’t clearly displayed before you, cleaning them can often go overlooked.

Buildup of mold, dirt and other particles is one of the more typical culprits of odor with air conditioners. It can occur with the coils, drain pain, air ducts or even your filter. Luckily, ongoing maintenance can help avoid this buildup and reduce the chances that an unfriendly smell starts dispersing throughout your space.

Heat and moisture can contribute to increased mold growth, particularly in warmer climates. Not only can mold and mildew develop a nasty smell, but it can also negatively impact the quality of air in your house.

It’s also possible that a little critter navigated into your duct system and died. You can turn off your air conditioner and either give our team or pest control a call to come and get the animal.

What can I do?

Analyze your filter. This is a usual culprit for air conditioner odors. If it’s been a long time since you’ve exchanged your air filter, replace it with a brand new one. We typically recommend changing your filter every two to three months. But it’s also key to keep in mind other elements that would require you to replace it more repeatedly, such as pets in the home or if a family member has allergies or asthma.

If you’ve exchanged the filter and it’s not making a difference, it’s probably time to reach out for some help. Especially if it’s been an lengthy period of time since your last air conditioning inspection. They can assess the situation to see if a thorough cleaning can do the job. You might consider having your air ducts cleaned. Professional duct cleaners can take a look to see if your indoor air quality would improve from a proper cleaning.

If you have concerns about the odors in your home, Fire & Ice HVAC can help you assess the situation and discuss possible solutions. You should be able to enjoy your cool indoor space during the warmer summer months, without having to suffer with unfavorable odors.
