Frequently Asked Questions:

These situations come up in some combination and in one form or another on every job. Be prepared! If you need assistance, we can guide you through the entire test and balance process.


Do I need my report to get my Final Certificate of Occupancy?
Believe it or not, you don’t have to have your test and balance report completed before you get your final inspection. In almost every case, as long as you have secured (have under contract) test & balance services, they will issue a temporary CO pending your balancing report submission. They understand there are scheduling constraints, especially if you have been surprised by the need for a TAB Report.
What is your turn around time?
Once you’ve secured our services, we schedule the work to be performed … which has an associated timeline for completion. Any delays (see above) will increase this timeline. Typically, once the final trip to the job site is made, and testing is completed, reports are typically rendered within 3-5 business days.
Scheduling TAB Work
Scheduling test and balance work is of the utmost importance. Make sure the job is 100% complete and “ready to be balanced” as per our pre-balance checklist. Please be cognizant of our schedule and other clients time frames and constraints as well. Having to come back due to unforeseen issues complicates everyones schedules and time lines. Do what you can to be prepared and on point.
What if something goes wrong?
Things go wrong … as they typically always do. If you have a mechanical delay during the job, and we can move on … repairs or corrections can be made while we are still on site testing other equipment. We typically allot for these issues and we do provide a one time courtesy return. Beyond that, delays of significance are billable, and will be subject to scheduling opening as they become available.
Testing does not mean passing.
It is greatly misunderstood … but just because you get a test and balance performed does not mean you will pass. While most systems pass initially, whether or not your project does lies solely on proper design and installation. Improper design and installation, along with VE (Value Engineering) is one of the largest causes of failure in delivering proper design system performance.
What if I don't pass?
This is a sore subject. Testing and not passing usually reveals poor system design, violations of installation “good practice”, and questions of competency. LaminAir does all we can to achieve a passing result. In the end, liability and responsibility fall on the design engineer and the installing mechanical contractor.
Balancing Re-Test Costs
If your project has only one part that initially fails, it will need to be retested. Our proposals are based on a one time through testing scenario. In the event you need a system or job re-tested, applicable re-test fees will apply.

Test & Balance Process:


Initiate Balancing Request

Contact us to get the ball rolling. We will need plans, specification, job site information, construction status, dates / deadlines, etc.

Provided Requested Documentaion.

Provide us with any documentation we need to fulfill your needs and requirements.

Provide Accurate Information

Providing us with the most accurate information is critical in the proposal process. Inaccuracies or incomplete information can negatively impact scheduling and final cost of the job.

Ready for Balancing

LaminAir has pre-balance checklists to ensure your job runs smoothly. Not being 100% complete and fully functional and operational is the number one cause of delays in obtaining your final certificate of occupancy.


The most common causes of delays are mechanical failures & repairs, life safety testing, and site access restrictions. In order to move things along and keep your project on time, work with all trades to maintain on time workflow.

Duct leakage and poor installation accounts for 35 – 65% of equipment operating costs. Most systems have air leak out of the ducts before it even gets where it’s going … Testing, Adjusting and Balancing will help you pinpoint your problems and start saving you money almost immediately! Duct Leakage

Not meeting your building’s fresh air requirements will have a significant effect on your indoor air quality. Not having enough fresh air can lead to sick building syndrome, comfort issues, and temperature / humidity variances that can lead to odor creation or mold growth. Fresh Air

A system that is not properly installed or operating at peak efficiency will have a detrimental impact on the life of your equipment. In severe cases, poor installation practices could void the warranty on your HVAC System and cost you thousands of dollars to correct. Breakdowns & Efficiency

What is a Test & Balance Report? Were you just told you need one? Don’t know what it is? Need one for your Occupancy Permit?

The requirements for Test & Balance Reports, and checking air flow and system performance is on the rise. More and more, Villages and Municipalities are requiring these tests and reports to certify that a system is performing the way it was designed and intended to.

Air Flow Testing has come to the forefront over the years due to recent changes in the energy & building codes (IECC & IMC).

If you were recently informed that you needed, or surprised to find out at the end of the project that air flow testing (A.K.A.: Certified Test & Balance Report, TAB, Test & Balance, Air Balancing Report, etc.) required on your project when you never needed it before  … get used to it. Due to recent changes in the code requirements, you will likely need this on every future commercial project you have … so make financial allowances for it.

We provide professional, certified air flow testing & air flow balancing services and reports in Chicago and the surrounding suburbs on the following types of equipment:

Residential HVAC (heating and air conditioning systems), including residential air flow zone systems.

Commercial HVAC (heating and air conditioning systems), including kitchen exhaust hoods (type 1 and 2), kitchen exhaust fans, RTU’s (Roof Top Units), Economizers for RTU’s, MUA’s (make up air units), AHU’s (Air Handling Units), and VAV boxes.

We perform our certified air flow testing in and around the greater Chicago Metro & North East Illinois area, and outlying suburbs.

We will also perform our services throughout the Mid-West regional area (by appointment only) and extend those services throughout the United States (travel & per-diem rates apply).

(Submittal Package & Standards available upon request).

Additionally, LaminAir holds an NCI (National Comfort Institute) Certification in both residential and light commercial air flow testing, balancing, and diagnostics..

These air flow testing certifications require renewal & recertification every two years, and NIST Certified instrumentation calibration checks every year / 12 – 24 months.
