HVAC System Cleaning: Banish The Nasty Things From Your AC

HVAC System Cleaning

Every day, your heating and air conditioning systems filter the air you inhale. Filters, ducts, and other equipment parts can become clogged with dirt, polluting bacteria, virus particles, and disease-causing bacteria over time.

Your HVAC system may be hidden from view, so cleaning it can be difficult. It is important to understand that your HVAC system can contain harmful substances. This is just one reason HVAC system cleaning can be so important.

This shows that HVAC system cleaning is not only a matter of fear. HVAC cleaning is now more important than ever, as COVID threatens to spread throughout our buildings.

Continue reading to find out about five things you can do to fix your HVAC system.

Bacteria and viruses

Contaminants can quickly spread through your air conditioner. Sick Building Syndrome is a condition where an entire building is connected to a common HVAC system with ductwork. If your building becomes sick, everyone else in it can get sick.

When bacteria or viruses are introduced to your AC system through your ductwork, they can spread quickly throughout your building. Regular HVAC system maintenance, including changing filters, cleaning coils, and cleaning the ductwork, is essential to eliminate contamination.

Other air quality options can help keep your space safe from COVID spread.

Mold and mildew

Humidity is the main factor that causes most contaminants to worsen, but mold depends on it. Your AC may not be able to remove enough moisture from the air. This creates ideal conditions for mold growth. Many types of mold can cause allergies in people, especially children and those with asthma. Some types can even create dangerous toxins. Regular maintenance and HVAC system cleaning can keep your ventilation clean.

Chemicals and VOCs

Many things in an office building can emit chemicals known as VOCs that can harm your health.

VOCs (or volatile organic compounds) are gases that can be emitted from a range of building materials. VOCs include formaldehyde and ozone. Ozone can be found naturally at higher levels in the atmosphere but is dangerous to breathe. Office supplies, such as:

  • Copiers
  • Printers
  • Adhesives
  • Permanent markers

The emitted formaldehyde, and other volatile organic compounds, are:

  • Carpets
  • Paint
  • Cleaning supplies
  • Gasoline
  • Pesticides
  • Cigarette smoke

While most emitted chemicals do not pose a danger in small doses, they can be dangerously high in large quantities. The concentration of chemicals in the air can increase if it is not well ventilated or sealed off.

According to the EPA, VOCs can be up to ten times more concentrated indoors than outdoors. It is important to remember that HVAC system cleaning does more than just clean your AC. It is vital for indoor air quality maintenance.

HVAC system cleaning can make the difference between a safe work environment and one that is dangerous. Poor ventilation and high humidity can make it more difficult to remove chemicals from the air. These chemicals can be eliminated by ensuring that your HVAC system is properly ventilated.


It can feel like you are in refuge from the pollution and smog of big cities when you live and work there. Indoor pollution can cause problems. An HVAC design that is good in rural areas may not work well in urban areas. It can also attract pollution from the outside. Air conditioner filters can trap pollutants, so HVAC system cleaning is important to keep these pollutants from getting trapped.

Poor ventilation is the main cause of interior pollution. Poor ventilation can lead to high levels of contaminants in the air system. Polluting substances can also linger in the atmosphere due to humidity.

Pet dander and dust mites

You probably already know that you don’t need to have allergies to cats or dogs to get your symptoms. Because animals shed fur and dander, this is a common problem. This is just one example of what could be causing your air to become dirty.

Another reason HVAC system cleaning might be necessary is because of dust mites. Dust mites, which are usually tiny and microscopic, thrive in humid, warm environments. If not cleaned properly, HVAC ductwork can collect a lot of dust. Parts of an air conditioner can also become warm and absorb moisture. This is the ideal habitat for dust mites.

A clean HVAC system is essential for any space that houses animals. To collect pet dander better, make sure you change or clean your filters frequently. You can avoid dust mites by hiring a duct cleaning service.

Neglecting HVAC system cleaning can cause physical symptoms

A dirty HVAC system can cause serious health problems for your employees and the residents of your building. These are the symptoms of a “sick building”.

  • Congestion in the nasal
  • Eye irritation
  • Coughing
  • Skin irritations and rashes
  • Muscle cramps
  • Headaches and dizziness
  • Fatigue
  • Worsening asthma symptoms

Signs that your HVAC system is not being cleaned properly

How well maintained an HVAC system is will directly impact the air quality in a building. These are signs that your HVAC system needs to be cleaned.

  • Chemical odors or musty odors
  • Water damage and leaks
  • Air that is too stale
  • High humidity
  • Dust entering the vents
  • AC not working properly

HVAC system cleaning services: What to look out for

Check the humidity levels

We’ve seen that humidity can play a major role in the growth of HVAC contaminants. Malfunctioning air conditioners can cause a buildup of heat and water in the ducts. This is the ideal environment for bacteria, mold, and mildew. This can lead to increased pollution and, in extreme cases, can even cause Sick Building Syndrome. For advice, contact a professional HVAC company if your space is constantly too humid.

Hire furnace and air conditioner duct cleaning service

Duct cleaning is an important part of HVAC system cleaning. Your furnace and air conditioner ducts can hold many harmful things and circulate them throughout your house. You might notice signs that your furnace and air conditioner need cleaning. These include moldyodors and dust coming out of the vents. If your HVAC is contaminated with mold or dust mites, duct cleaning will be the best way to fix it with the help of professionals like dryer vent cleaning Irving.

Preventative maintenance plans will keep your HVAC system in good condition so that you are not concerned about potential problems. Regular filter replacement is part of preventative maintenance plans. This will prevent the buildup of bacteria, viruses, or mold. Your coils, drains, and pans as well as other components of the system will also be cleaned.

While it is true that pollutants, such as mold and dust, can build up in your ventilation system, this doesn’t always happen overnight. Regular inspections can identify potential problems and alert you if the system is susceptible to becoming contaminated by humidity or airflow issues. Regular maintenance and HVAC system cleaning are key to preventing contamination.
