When I moved into my first place, I couldn't believe how dirty everything was all the time. I found myself dusting and mopping continuously, only to deal with a fresh layer of grime later. After awhile, I realized that the problem was blowing straight out of my air ducts. My ventilation lines were so dirty that it was spreading grime through my house every single time the air clicked on. Fortunately, I called an HVAC contractor who was able to clean my vents to a gleaming shine. I know how big of a difference cleaning up your ventilation system can make, which is why I want to spread the word.
When you get home from work and instead of being greeted by a fresh-smelling home, your house is filled with unpleasant odors, your HVAC may be to blame. Your HVAC can produce a variety of odors that are caused by different things. Some are alarming, such as electrical burning odors and the smell of a natural gas leak, and these require emergency service. Other odors are puzzling and you may wonder what's causing them. Here are some reasons your HVAC may be making your house smell bad.
Dirty Coils Are Breeding Bacteria
When your HVAC unit is dirty, bacteria can grow. This might happen when condensation gets the dust damp and the grime clings to the inside of the HVAC. The odor caused by bacteria can resemble the odor of smelly socks and make your home smell unpleasant. This problem can often be avoided by having your HVAC unit cleaned by a professional at least once each year. If your unit hasn't been cleaned lately, then consider scheduling a service call so the coils and other parts of the HVAC can be cleaned and sanitized to get rid of bacteria and the odors they cause.
Mold Is Growing In Your HVAC
When mold is growing inside your HVAC or in the ducts, your home may take on a musty odor. If you have sensitivities or allergies, you may also notice an increase in your symptoms when you're at home. Mold grows when there's a dampness problem, especially if there is dirt for the mold to thrive on too. The solution is to have your HVAC cleaned to eliminate the mold and to repair any problems that may be contributing to an increase in moisture such as a clogged condensation line or pan that won't drain. If mold is in the ducts, you'll want to have the ducts cleaned and sanitized as well to eliminate the odor and reduce the number of mold spores being blown into your living space.
Mice Have Invaded The HVAC System
If mice infest your HVAC, they can make your house smell bad due to all the urine and droppings they leave behind combined with their body odor. However, if mice invade the HVAC or ducts and die in there, you'll have a real problem since the air that blows into your living space will pick up the scent from the dead animals. Mice and rats try to get in your attic in the winter to get warm or to look for food.
The inside of a duct may seem like a nice place to make a nest, but the animals not only stink up your home, they can cause heat to leak into the attic and make your HVAC less efficient. You definitely want damaged ducts to be repaired promptly and to have the ducts cleaned and sanitized after rodents have been in them.
