Mold and mildew
Most contaminants are aggravated by humidity, but mold relies on it. If your AC is having trouble removing enough moisture from the air, it creates the perfect conditions for mold. Most types of mold can cause allergic reactions in some people, particularly children, the elderly, and asthma sufferers. Some types can even create dangerous toxins. Regular maintenance and HVAC system cleaning will keep your ventilation clean and mold-free.

  1. Pollution
    When you live and work in a big city, it can seem like going inside is a refuge from the pollution and smog-filled air on the streets. But pollution can also cause air problems indoors. An HVAC design that works well in rural areas can be wrong for urban environments, and even draw pollution in from outside. Pollutants can wind up trapped in ac cleaning filters, making HVAC system cleaning an important part of keeping these pollutants out.

Poor ventilation is a major cause of interior pollution. If vents can’t circulate or filter air well, contaminants will build up in the system in high concentrations. Humidity makes pollution linger in the air as well.

  1. Dust mites and pet dander
    If you’re allergic to dogs or cats, you probably know that an animal doesn’t have to be in the same room to stir up your symptoms. This is because animals tend to shed and leave behind fur and dander. That’s just one example of something you can’t see that could be making your air dirty.

Dust mites are another reason you might need HVAC system cleaning. Dust mites are tiny, usually microscopic insects that feed off of dust and thrive in warm, humid environments. HVAC ductwork can accumulate lots of dust if not properly cleaned. At the same time, parts of an ac cleaning are warm and collect moisture. This makes it the perfect habitat for dust mites.

If your space has animals, a clean HVAC system is a must. Make sure to clean or change filters often to help collect pet dander more efficiently. Duct cleaning services can help you avoid getting dust mites. (More on duct cleaning in a minute.)

Physical symptoms of neglected ac cleaning
Not having a clean HVAC system can be harmful to your employees or inhabitants of your building. Here are some ways the people in an infected building might get sick.

Nasal congestion
Eye irritation
Coughing
Skin irritation and rashes
Muscle cramps
Dizziness and headaches
Fatigue
Worsened asthma symptoms
Building symptoms of neglected HVAC system cleaning
The air quality conditions of a building are directly related to how well treated its HVAC system is. Here are some problems you might notice that’ll signal you to get HVAC system cleaning.

Musty odors
Chemical odors
Leaks and water damage
Stuffy air
Dust coming through the vents
Poor functioning AC

MONITOR HUMIDITY LEVELS
As we’ve seen, humidity is possibly the greatest factor in the development of HVAC contaminants. Malfunctioning air conditioners create a build up of heat and moisture in the ducts, which is the perfect setting for mold, mildew and bacteria. It can worsen pollution, and in the worst cases can even lead to symptoms of Sick Building Syndrome. If your space is consistently too humid, call a qualified HVAC service company for advice.

GET DUCT CLEANING SERVICES
One of the important parts of HVAC system cleaning is duct cleaning services. The ducts of an air conditioner can harbor many nasty things, and circulate those things throughout the house. There are many signs you might need duct cleaning, including seeing mold, bad smells, and seeing dust coming out of the vents. If an inspection discovers that your HVAC has dust mites or mold, duct cleaning is the best option to take care of that problem.
