Indoor Air Quality is as important as ever to your customers, tenants, patients, or those that live or work in any commercial and industrial building. Notwithstanding the health concerns of air quality, a well-maintained duct and air distribution system by our CARE SERVICE® Maintenance Plans extends the life, efficiency, and throughput of any modern HVAC system.  

We are pleased to offer professional IAQ services. Our approach to Indoor Air Quality evaluations is discreet and non-disruptive. Recommendations, if required, are provided professionally and confidentially.

Did You Know our CARE SERVICE® Maintenance Program Covers Filters and Filter Changes?

Krauss Company’s CARE SERVICE® Maintenance Programs cover filter changes. Also included is regularly scheduled maintenance, which ensures your building or facility is “breathing” comfortable and healthy air. Why worry about the air in your building when you have a timely and regular schedule of filter changes? We only use top-quality, industry-leading filters to fit nearly any application or type of HVAC system with air distribution ducting. 


Air distribution systems provide the “air plumbing” to your building. They are responsible for the supply and return of cooled or heated air. The exchange of air through this ductwork is vital to your major HVAC equipment’s maximum efficiency.

Any buildup, animal dander, dust, dirt, and debris can affect the turnaround time of heated or cooled air. Longer run times put your facility at a disadvantage on many aspects up to and including:

  • Increased wear and tear on major components
  • Longer times to cool or heat a space
  • Increased utility bills due to longer run times


Properly maintained filtration systems within your building provide an excellent health benefit to your occupants.  Did you know that a properly outfitted system can remove up to 60% of harmful contaminants out of the air we breathe?  Contaminants can range from foul odors, mold, dust, bacteria, and viral droplets to name a few.   Indoor air quality is especially important in urban areas where there is a greater concentration of smog and other pollutants.  

  • Clean and healthy fresh air for your occupants
  • Quicker heating and cooling response times in conditioned spaces
  • Increased workplace productivity 

Duct Cleaning, Repair, and Replacement

A vital component to Indoor Air Quality is the cleanliness of your air ducting.   Whether your air distribution network is flexible ducting or rigid frame sheet metal, we have the capability of cleaning and sanitizing your existing network of air handling components.  Perhaps your system is aging or beyond economical repair.  Rest assured, our sheet metal services can provide a quality solution to meet the needs of your building and the comfort of your occupants.


Air Handling systems should be clear and clean from dirt, dust, buildup, and debris.   Resistance in the air flow from conditioned spaces results in harder working mechanical equipment which shortens the lifespan of a heating or cooling system.  Duct cleaning generally refers to the cleaning of various heating and cooling system components of forced air systems, including the supply and return air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, condensate drain pans (drip pans), fan motor and fan housing, and the air handling unit housing.  Our Indoor Air Quality Assessment will consist of: 

  • Thorough visual inspection of air ducts and registers
  • Borescope to access hard to see areas
  • Sealing check to ensure that all of your air is going to it’s desired space


Properly maintained ductwork and air distribution within your building directly affect your heating and cooling bills. In the long run, this provides the maximum lifespan of your more expensive HVAC equipment.

With the cost of utilities constantly rising, wouldn’t you want to get the utmost life out of your HVAC system?

Our Indoor Air Quality Assessment can determine which components are working the hardest in your building, which will identify problems in your air distribution system. Our assessment will check for:   

  • Components with the longest life history
  • Recommendations for replacement or retrofit as necessary 
  • Diagram your air distribution system to outline inefficiencies and recommendations for repair or replacement 

COVID Response

Indoor Air Quality has been thrust into the forefront with regard to the recent pandemic regarding COVID19.  Did you know a properly maintained filtration system is a preventative measure to ensuring your building occupants are doing all they can to prevent the spread? A good quality filter and maintenance program such as our CARE SERVICE® Maintenance program can effectively reduce the concentration of airborne particulates of the virus as well as other harmful biological agents.  Contact us today for a free assessment of your air distribution system. 


Much is still to learn by the Centers for Disease Control and other agencies regarding the SARS-CoV-2 virus. However, nearly everyone agrees that this pandemic will spread through viral droplets from an infected person or carrier. See here for more information.

Why not let Krauss Company thoroughly assess your indoor air quality to determine problem areas? Our Indoor Air Quality assessment will determine how the functionality of your equipment is operating so that you have a piece of mind regarding your conditioned air spaces.

We employ a healthy staff that is stringently monitored for conditions so you can assure you are providing the cleanest and healthiest air to your occupants.    

Our Indoor Quality Services can identify and conduct:

  • Potential areas of moisture saturation resulting in mold and other growths
  • Microbial Surface Sampling with Independent Laboratory Analysis
  • Controlled Air Sampling
  • Comprehensive reports on contaminants
  • Areas of concern


Our Indoor Air Quality Assessment can evaluate your space discreet and non-disruptive manner. Our assessment, combined with a thermography evaluation, will provide you with a proactive approach to your Indoor Air Quality (IAQ) needs.

IAQ can be affected by gases (including carbon monoxide, radon, volatile organic compounds), particulates, microbial contaminants (mold, bacteria), or any mass or energy stressor that can induce adverse health conditions.

Source control, filtration, and ventilation to dilute contaminants are the primary methods for improving indoor air quality in most buildings. With proactive service in mind, it is better to be prepared and have full working knowledge of your air quality.

Our Services can include evaluations on:

  • Temperature and Humidity Ranges
  • Building Pressurization and Air Balance
  • Filtration Efficiencies and Effectiveness
  • Ductwork and Air Handlers
  • Borescopic Inspection with Video Documentation
