Everybody loves air conditioning. It is always great on a hot summer day to be able to go into your home, and feel the nice, cool air flowing. However, sometimes that air can have an interesting smell to it. Many of those smells are natural and harmless, but some can be cause of concern. So lets take a look, or better yet, take a sniff at some of the smells coming from your HVAC system.

Musty Smells

If you smell a musty smell in your home it could be an indicator that there has been moisture build up in your ducts. Excess moisture can cause mildew and mold to grow in your system. The process of removing moisture from your air, otherwise known as dehumidification, can cause water to collect on both the coil and the air filter. If this water sits for an extended period of time in can cause mildew and mold to form. Luckily, replacing your air filter and ensuring your drain pan is not clogging can usually solve this issue.

Dead Animal Smells

This next smell is an unmistakable one. It is the smell of an animal that made its way into your ductwork and didn’t make it’s way out. If the animal is within reach of a vent or other accessible opening, you can remove it yourself. However, if you are unable to find the dead animal, you will need to call a qualified professional to get it removed.

Burning Smells

Do you smell something burning? If you do, it is very important that you turn your system off immediately. A burning smell can be an indicator that your compressor or your air conditioner fan may be burning out. This may be very hard to diagnose without proper HVAC knowledge, so making a call to a professional is always the best option here.

Rotten Egg Smells

If you smell rotten eggs and you know that you didn’t hide any Easter eggs in your vents, it can be a big cause for concern. That rotten egg smell may actually be natural gas. Because natural gas is odorless, a rotten egg smell is added to it to get a homeowner’s attention when there is a gas leak. If you believe you have a gas leak, it is imperative you leave your home as safely as possible. You then need to call your gas company to have the smell checked out by a professional.

Cigarette Smells

Another distinct smell that can run through your HVAC system is the odor of old cigarette smoke. If you have smoked cigarettes in your home in the past or if the previous owner of your home was a smoker, you may have stale cigarette smell circulating throughout your home. This is one of the more difficult smells to remove, because it can stick to your carpet, walls, and ceiling. One of the easiest ways to help rid the problem is simply to ensure no one is smoking in your home anymore. The second best way is to change your old air filters to make sure they are capturing as much of the odor as possible. Also using an odor eliminator, can help get rid of the smell.

If these two methods prove unsuccessful, you should highly consider installing an Air Scrubber into your home. Air Scrubbers use patented NASA technology to remove up to 99% of both surface and airborne contaminants. An Air Scrubber is not only a fantastic defense against cigarette smoke, but any smell that may be lingering throughout your home.
