What Is Negative Air Pressure? How Can It Be Corrected?

Monday, September 13th, 2021

commercial-hvac-fans-in-rotationWhen you think about indoor air quality problems for your commercial facility, your mind probably goes directly to contaminants circulating through the ventilation system or various indoor pollutants. But one of the biggest issues for commercial indoor air quality is negative air pressure

The simple definition of negative air pressure is that it’s when the air pressure inside the building is lower than the pressure outside the building. This often happens in commercial and industrial facilities because of over insulation designed to improve energy efficiency. If not enough outdoor air can enter because of the strong heat-sealing, the indoor pressure will be lower than the outside. Negative air pressure can also happen because of poorly constructed or damaged ventilation systems or malfunctioning equipment that draws on too much air inside the space.

What Is Negative Air Pressure?

Monday, April 12th, 2021

clouds-in-skyNegative air pressure inside a building creates problems for both homes and commercial/industrial facilities. The simple description of negative air pressure is that it is when the air pressure inside a building is lower than the air pressure outside it.

This may not sound like a huge problem, but for a commercial or industrial building, negative air pressure can create several major issues that need to be addressed with proper ventilation and air pressure balancing.

Commercial Ventilation in Early Spring

Monday, March 16th, 2020

commercial-lobby-with-vents-ductsProper ventilation for a commercial facility is essential, regardless of the type of facility. Ventilating a space is required to allow for proper humidity balance (which can make or break process for many businesses), healthy conditions for workers and employees, control of mold and mildew issues, mitigation of allergens, and reduction of dust and other contaminants that can cause damage to machinery.

Early spring is a tricky time for ventilation, as the weather begins to shift between warm and cold, and facilities deal with the need for both commercial cooling and commercial heating in Toronto, ON. Indoor air quality in a commercial facility can lower rapidly during spring if the ventilation system isn’t kept in proper shape, the ventilation system is outdated, or the wrong type was installed.

The Make-Up Air Unit and Winter Indoor Air Quality

Monday, December 24th, 2018

sun-and-snowflake-badgeDuring winter weather, concerns about the air quality inside commercial and industrial buildings is higher than at any other time of the year—especially in a place like Toronto, where the temperatures stay below freezing for most of the season. Fresh air circulation in a building simply doesn’t happen during cold weather when an indoor facility must be sealed off from the outside, so matter the type of facility.

The lack of fresh air ventilation not only leads to a buildup of indoor contaminants and imbalanced humidity, it can also cause negative air pressure inside a building—too much air exhaust, not enough air brought in. This is where the make-up air unit can be invaluable. If you aren’t aware of make-up air units and their use, we’d like to show you what they may be able to do for you.

Proper Commercial Ventilation Is Critical for Indoor Air Quality

Monday, October 2nd, 2017

commercial-ventWe offer numerous commercial HVAC services in Richmond Hill, ON and throughout the Greater Toronto Area. When people think of commercial HVAC, they usually focus on the “H” and “AC” parts, heating and air conditioning. It’s true that a huge part of what we do is helping commercial and industrial facilities maintain proper indoor temperature control, both for comfort and to facilitate process and protect equipment.

But let’s focus for the moment on the “V” part, ventilation. A vital service we offer for commercial and industrial companies is commercial indoor air quality. Indoor air quality is about the air customers and employees breathe, the dust contamination that can damage machinery, and the shifts in humidity that can affect both people and equipment. Better indoor air quality is essential for most facilities, and there are many methods we use to improve IAQ, such as powerful air filters, electronic air purifiers, dehumidifiers, and humidifiers.

That “V” is critical. A facility without proper ventilation will end up with poor indoor air quality no matter what. Depending on the building or facility, it can even lead to a dangerous work environment.

Negative Air Pressure and Importance of Make-Up Air Units

Monday, May 15th, 2017

commercial-air-duct-largeWe are proud of the large number of services we provide commercial and industrial companies in the Greater Toronto Area. We’re a heating, cooling, and ventilation contractor, but people often overlook the “ventilation” part—the “V” in HVAC. The truth is that while maintaining the proper level of temperature inside your commercial or industrial facility is essential for continued operation—it not only offers comfort for people, it’s often vital for the proper protection of equipment as well as process—the indoor air quality is also essential. As with heating and cooling, it affects people, equipment, and process. Our technicians are experienced with handling the many ventilation needs of buildings for the best indoor air quality in Toronto, CA and the surrounding areas.
