$$$ Going Up The Exhaust Hood

We can help you take control of your building heating system and fuel bills by properly adjusting your existing exhaust / make-up air system. Most systems we find are improperly adjusted causing too much negative pressure in the building. The result is arctic blasts when doors are opened and bigger heating bills....

We also find many make-up air units that are shut off or never repaired because of the conception that it costs too much to run them. After all, it's hard to imagine heating up a large amount of outside air to pump back out the hoods. But the air has to come from somewhere - in proportion to the amount being exhausted - so it comes in from where ever it can: open or leaking doors, windows, ducts, chimneys and vents. Instead of filtered, conditioned air being brought in near or at the exhaust hood/s, outside air is sucked in from various undesirable points.

Another very important, often overlooked problem with negative pressure, is it's effect on gas burning equipment inside the building, such as water heating equipment and boilers. Unless you have a sealed combustion unit, proper venting of potentially dangerous flue gases cannot be accomplished and are dumped in the mechanical room. Draft inducers are frequently installed on typical atmospheric units (hot water tanks or boilers) but can only overcome moderate negative pressure. Inadequate venting is the major cause of heat exchanger failure which usually means unit replacement. A potentially bigger cost is from cold air being drawn down the flue piping during every off cycle and cooling down the heated water.

Call a qualified contractor and have your equipment checked and adjusted if necessary. You'll have more comfortable customers and lower HVAC costs.
