Is Your HVAC System Harming Your Indoor Air Quality?

Is Your HVAC System Harming Your Indoor Air Quality?

Did you know indoor air quality has been proven to be far more polluted than outdoor, even in cities with a lot of industrial use? However, an efficient HVAC system can make a huge difference when it comes to indoor air purification in Knoxville. It can help filter out dust, pollen, and other airborne contaminants from the air you breathe. The keyword here is ‘efficient.’ If your HVAC system is poorly maintained or is not the appropriate size for your property, it could have the opposite effect and start to have a negative impact on your indoor air quality.

Let’s take a look at some of the warning signs that your HVAC might be having a negative impact on your indoor air purification in Knoxville.

Your Room Feels too Humid When AC is On

The main role of the air conditioning part of HVAC is to cool the air and keep the humidity at a constant, comfortable level. However, since your AC is controlled by temperature, it is important to use the appropriate unit for your space. If your HVAC unit is too large for the size of your home, you will find that it reaches the correct temperature too quickly without leaving time for humidity to be reduced. When low temperatures are coupled with high humidity can leave the room feeling uncomfortably humid, like sitting in a refrigerator!

You Notice Drastic Differences in Air Temperature

For both heating and air conditioning systems, you should be able to maintain a steady, comfortable temperature. If your HVAC system is much larger than what is required for the space you are heating and cooling; then you may experience drastic shifts in air temperature. Your equipment will attempt to conserve energy by operating for short periods, but it will create fluctuating temperatures and poor humidity control because it is oversized. This can create an uncomfortable environment, especially in the workplace.

You Smell Unpleasant Odors From The Air Ducts

Adequate ventilation is an integral part of your HVAC system, but it can also result in air quality issues such as unpleasant odors being released from the air ducts. If you are smelling something unpleasant in the air ducts, there could be several causes. Some of the most common include:

  • The source of the odor is inside the air duct itself. It could be mold growth due to a build-up of moisture, or if any of the ducts are not securely sealed, it could be a rodent or other small animal that has gotten inside the duct and died.
  • The odor could be sucked in from outside. This can happen if you have leaky ducts or loose connections between ducts and HVAC equipment.
  • Odors can be pulled from other parts of the building. This situation means that the ventilation system is not effectively supplying fresh air. This can result from obstructed ducts or incorrect balance between injection and extraction fans.

No matter what turns out to be the root cause of the unpleasant odor, these smells are a strong indication that your HVAC requires inspection and/or maintenance. It is important to book regular professional servicing for your HVAC system for continuous indoor air purification in Knoxville.

It Seems Occupants Are Often Sick

Have you ever heard of ‘Sick Building Syndrome? This is a term used to describe what happens when a high proportion of the occupants of a building experience health problems when spending a lot of time inside the building in question. It is not a specific condition but a catch-all term for a variety of health concerns such as allergies, respiratory illness, or headaches. Sick Building Syndrome often rears its head when there is a lack of clean air, uncomfortable temperatures, excessive humidity, or the presence of harmful irritants or bacteria in the air. An inefficient HVAC system is often the culprit for all of these problems.
