This air is then distributed throughout a commercial space or building by the use of a blower fan motor through a single or multiple ducting within the building. Make up air unit  are set up only when negative pressure caused by a forced-air heating system occurs. This is where the building is sealed and insulated properly, hence resulting in negative pressure developing inside. Rather than allowing this negative pressure to cause infiltration around doors, windows or wherever an unintended opening might be, contractors can do make up air unit installation . This unit maintains output temperature between 55-75 degF. 

We are so happy that we called Joel and his team to repair our furnace. We were without heat for a week or so. We had contacted a few companies and none were able to properly diagnose our problem, instead we had 3 parts replaced and our heating system still did not work! Hundreds of dollars later we were lucky to be referred to Knowledge HVAC (and that is the perfect name for them, because they are quite knowledgeable!) Joel was able to come the same day and diagnose the problem for us. We hired him and his team to repair our furnace the next day, they were fast and efficient and we now have some heat finally! We are so happy we called them. I give them 5 stars for excellent service! I will definitely call them again if needed and will recommend them to my friends and family. Very pleasant experience, very nice guys! Reasonable rates.

I called around for a quote, and Knowledge was the first to call back. He gave a quote and was able to help the very next day. Joel and his team is very friendly, professional and knowledgeable. Very reasonably priced. I had a gas line system installed on my food truck. They did an awesome job, and put in extra time to get the job done on schedule.

Ensure optimal working conditions with automatic management of IAQ, consistent temperature, and controlled building pressure.

There are two common places where make up air unit installation for a building: directly on top of the roof or on the size of the building. These units would be installed on a ducting system in addition to supply fresh air to the building. Another side effect of negative pressure is where the building becomes starved for air, which negatively affects doors and windows, hence reducing building air quality. Since these systems bring in a constant supply of fresh air from the outside, ample air is available for building air quality which improves building efficiency. Current building codes and regulations required the use of makeup air units to prevent negative building pressure. 

It is recommended by the manufacture that make up air unit  install, repair and service of equipment be inspected once per year for safety and proper operation.
Failure to do so may result in Bad Air Quality, Equipment Failure, Carbon Monoxide Poisoning etc.

The Importance of Makeup Air Systems

Makeup air systems are crucial in reintroducing vented air, especially in buildings lacking such systems. Without proper ventilation, exhaust fans in bathrooms and kitchens can create a depressurized environment. This can result in air seepage through cracks or leaks, impacting air quality. Makeup air systems are essential to circulate fresh air, ensuring a safe and healthy indoor environment.

Why it Matters:

The absence of a makeup air system can compromise the air quality within a building, posing potential health risks. Proper circulation through an HVAC system is vital to maintaining a safe and comfortable environment for occupants.
