The panels are bolted on, the fan’s blowing, the motor’s running, and you can hear and feel the machine running. You’re good… right? No matter how in tune you are with your building, there are common HVAC issues that any facility manager won’t notice before they become problems. It doesn’t take long for innocuous sounds or slight inefficiency to become a big (and costly) problem for your building during winter.
Fortunately, generations of Yale Mechanical technicians have picked up a thing or two about winter checkups (nearly 80 years of business in Minnesota will do that). Here are a couple of easy-to-miss points to scratch off your winter HVAC checklist.
Unexpected noises can mean your equipment is working harder than usual or about to give out. An inducer blower (which helps make sure the right amount of air is moving through a boiler or furnace to ensure safe, clean combustion) that squeaks, for example, is working harder as the climate gets colder. The sound itself can be hiding issues like worn bearings or other parts, which can lead to headaches like poor performance and costly repairs.
The animal kingdom loves your building’s heating equipment for the same reasons you do: comfort and necessary warmth during the coldest times of the year. Creatures of all sorts, from hornets and spiders to mice and birds, love to inhabit vents like the ones on your gas regulator and inducer assembly. Needless to say, their tenancy isn’t safe for them, and it’s not good for your building, either; they can cause damage to your HVAC equipment, threaten air quality and pose health concerns for the people inside. Make sure your mechanical contractor checks for properly sealed openings and vents during maintenance.
Air filters are another common HVAC issue we see missed time and time again, particularly on a building’s economizer. Usually on the outside of the unit, most economizers have washable filters that often get missed in surface-level checkups. You might think of dirty filters as more of a quality-of-life issue, but they can mean severely decreased efficiency – and worse, system failure – if not regularly and properly addressed by professionals.
