What an HVAC Air Balance Report Template Is Used For

An HVAC air balance report template is a document to record the results of an HVAC system’s air balance. Air balancing involves assessing the amount of air at grilles and registers. An air balance report template walks you through the necessary measurements to evaluate the HVAC system. This report ensures customers receive quality airflow in every living area.

What does air balancing involve?

Grilles, registers, and diffusers will create a proper air flow through your system. This creates the standard proportional balancing to make sure things such as fan speeds and air volume works correctly.

Air conditioning fix

Typically, the air conditioning unit is the first to have issues that require a report to fix. When people get hot, they tend to use the air conditioner system often and very strongly, which causes it to break faster.

Evaluate the HVAC system

Sometimes, there may not be any direct problems and the system just needs a proper evaluation. This could be needed by customers who just bought a property and needs to check the system for repairs before opening it to the public, or even a new homeowner that needs to assess any damage before moving in.

What You Need to Know About HVAC Balance Reports

AABC

The AABC has created specific standards for the operation of these systems, as well as how to properly document them. It is important to make sure all certifications are AABC certified and you check into their qualifications to ensure everything is done correctly.

Diffuser Types:

The type of diffuser, as well as the placement of it, should be documented in your report. The ductwork typically has 3 different types, so it is also important for the homeowner to know which one is used in the system. Be sure to check that everything is sealed tightly as well.

Balancing dampers and diffuser

: a grille does not have a damper that is attached. The grille should have no moving parts, and you must check that everything is put together nicely to ensure that the air is balanced.

Why is makeup air critical

: here are plenty of appliances in the average home that could potentially depressurize the home as well as flow combustion gases into the living spaces. This is extremely dangerous, and makeup air helps prevent this.

Pitot tube traverse

: you can measure the airflow with a pitot tube, which will tell you all you need to know to determine the velocity pressure. An accurate measurement of airflow is absolutely crucial.

Airflow of exhaust fan

: you should also check the velocity in the exhaust duct. To find the airflow in the exhaust fan, multiply the average velocity by the area of the duct. You may be able to find the fan tables from the manufacturer of the specific fan online.

Exhaust duct system

: the exhaust duct system aids in keeping out potentially harmful substances in the air, such as dust, fumes, particles, chemical hazardous components, and shavings. This is crucial for both businesses and homes.

Supply air CFM

: to calculate the CFM, measure the width and length of a room as well as the height, multiply those measurements for the cubic footage, multiply that by how many times you wish to exchange air in an hour, and divide that answer by 60. It is important to understand how much the air should flow in a room.

Check exhaust-air dampers

: these dampers will allow air to flow through the exhaust ducts and outside while also making sure that unwanted airflow inside is prohibited. These are typically found in bathrooms, laundry rooms, and kitchens.

What is the Variable Air Volume (VAV)

: his is a type of heating, ventilating and air conditioning system that makes the airflow vary at a constant temperature.

Air handling unit (AHU)

: the Air Handling Unit will circulate and re-condition the air in a system. It utilizes the outside air to create fresh air for the inside.

Verify test data

: in just about every report, you will have to verify what you have found. This can include checking the system a second time, calculating the same problems over again, and looking up manufacturer information to match with the utilized parts of a system. Although verifying the information may seem redundant, it can help make sure that everything was gathered correctly and can prevent issues in the future.

Procedural standards

: the procedural standards for these systems have been established by the NEBB Procedural Standard for Testing, Adjusting, and Balancing of Environmental Systems. This set of procedures will ensure that the proper work has been done.

Pertinent design data needed for the balance report

: Typically for this system report you will need to provide a visual representation along with the required information to show where each part of a system has been placed.

Balance exhaust systems

: maintaining a balanced exhaust system is crucial in this report. Ensuring that it is balanced will help keep both people and the environment safe from potential issues with the airflow.
