Since one subset of the HVAC system can greatly influence the performance of another, all systems within the building should be balanced. This includes, but is not limited to: – conditioned supply air distribution – exhaust systems – make-up air systems – any hydronic systems (water balance)
FAQ Category: Understanding Test & Balance
Is leaky ductwork an issue with the air balance?
Yes, ductwork that is leaking air occurs when it is installed improperly. This is an important issue to fix because it is costing you money by conditioning an area that doesn’t need to be conditioned. And because duct is located above the ceiling, you’re probably losing conditioned air. This is an issue a TAB service […]
Can any HVAC system be balanced?
Yes, any HVAC system can and should be balanced to ensure proper operation, performance and energy efficiency.
What are signs that my building is out of balance?
The most common indicators are: – sweating diffusers – exterior doors that are hard to open – uncomfortable temperatures – drafts For those facilities with commercial kitchens, smoke-capture problems are a sign.
How does an air balance help my HVAC system be more efficient?
To correct a system that is over-ventilating, fan speeds are reduced and dampers are set to optimally regulate airflow for design performance with as little static pressure as possible. This reduces load on the motors and the energy required to operate them. An air balance also ensures that systems are not under-ventilating, which can lead […]
Why is HVAC testing and balancing necessary?
If you’ve ever been bothered by uncomfortable drafts of air or experienced room temperatures that are inconsistent with what the thermostat reads, then you’ll quickly understand why a test and balance is necessary. In short, unbalanced air prevents you from feeling comfortable. TAB ensures that your HVAC system is performing correctly and you have a […]
What is HVAC testing and balancing?
HVAC testing and balancing (TAB or air balance) is the process of ensuring that your heating, ventilation and air conditioning system is operating properly and delivering the correct air quantities at the air devices inside your building. This involves cycling the equipment on to verify functionality, measuring preliminary airflows, checking fan rotations, adjusting fan speeds, […]
