System of ventilating pipes
We recently discussed the problems of high humidity in buildings. In this post, we wish to talk more in depth about how we take a holistic approach to creating balancing humidity. A key part of this approach is managing humidity levels inside buildings through proper ventilation, air balancing, and dehumidification. As anyone who has gone through a single summer in Toronto knows, high humidity is a major problem—and it easily gets into buildings where it can cause significant damage beyond simply making a space less comfortable.
The standard measure of high humidity is relative humidity that’s greater than 60%. (Relative humidity is a measure of water vapor in the air relative to the temperature of the air, i.e. the percentage of water vapor in the air of the total amount that could be held at the current temperature.) Residential homes usually aim to balance humidity at 45%. But when it comes to commercial and industrial spaces the ideal humidity balance may be different based on equipment and process. This is one of the main reasons to work with professionals to combat humidity in your facility: our experts will know what humidity level is ideal for the space.
Negative 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. 
We’ve been working on commercial heating, cooling, and ventilation for more than three decades here in the Greater Toronto Area. We’ve seen it all when it comes to HVAC troubles for commercial facilities and buildings, from the routine and common to the very weird.
