As businesses in Boise, Idaho gradually reopen, buildings’ heating and cooling systems can do more than keep people comfortable. They can also keep them safe — but only if you use them in the right way.
In fact, it’s entirely possible that turning on your heating and cooling system right now in a bar, restaurant, auto repair shop, daycare, salon, or any other commercial space can be a bad thing.
That’s because these systems don’t bring in fresh air. Instead, they circulate what’s already inside.
There’s no way for airborne contaminants, including viruses, to escape once they’ve entered the building with this process. Instead, particles in one part of a room can travel to a different area. When this happens, you get a build-up of harmful microorganisms as they travel through the ductwork.
You won’t run into this problem when you’re outside, where fresh air is always blowing. This dilutes any concentration of pathogens — ideally, to the point where they’re almost non-existent. That’s why it’s okay to host outdoor dining or meet with people in parks or other outside spaces.
So, how do you get that fresh air effect inside?
In this article, we’re outlining the most efficient and effective ways to bring fresh air into your building. It’s especially crucial if you have windows that don’t open or if you rely on your HVAC system to keep your
Finally. We’ll close with ways to keep your customers, tenants, workers, and clients comfortable and safe this winter.
ERVs: Getting Fresh Air Into Daycares, Repair Shops, Offices, And More
The most efficient way to get fresh air circulating through your commercial space is with an Energy Recovery Ventilator (ERV). It allows fresh air to enter your HVAC system from the outside, which doesn’t happen otherwise.
Even though your AC condenser and a heat pump, if you use one, are outside, they don’t actually bring in outdoor air. Instead, they only treat the air that’s already inside.
An ERV changes that without you losing any heating or air conditioning.
These units connect directly to your HVAC system. And, they work automatically, just like your furnace or central air. There’s no turning them on or off. They’ll bring in a stream of fresh air from outside while another stream of “stale” air from the building gets sent out.
ERVs In The Winter
In the winter, an ERV transfers the warmth or “thermal energy” from the stream that’s on the way out and way in. This process keeps your heating but gets rid of the old air. When that outside stream hits the ductwork, it now has the heating that came from the furnace.
ERV’s In The Summer
You want to keep the temperature and humidity inside low, but you also want to flush out the stale air. This time, the thermal energy transfers from the inbound stream into the one going out. The exchange makes the incoming stream as cool as the air that was in there before.
The system also adds extra dehumidification on top of your air conditioning already doing that. This process accounts for additional moisture coming in from the outside stream.
Considering that, an energy recovery ventilator can make the indoor air quality of any space just as healthy as the air outside. Also, the fresh air outside is just about always cleaner than indoor air.
Best Ways To Keep The Air In Your Commercial Space Clean
Along with circulating in the fresh air, you can tout the “cleanest air on the block” using stronger HVAC filters and air purifiers.
Like your home system, your commercial heating and cooling system has a filter that traps dust and other tiny particles as they pass through the system. That being said, standard filters won’t catch contaminants as small as bacteria or viruses.
To start — make sure you change your regular filter every month or so. After that, you have a few options to improve your indoor air quality. You can upgrade to filters with higher MERV ratings. However, they come with a major caveat.
A filter also produces resistance that weakens the air circulation through your ducts and vents. Even though your standard filter produces a tiny bit of this resistance. As a result, you can damage your furnace or AC if you use a filter that’s too strong for your blower motor.
Now, an alternative to that process is using an air purifier that hooks up directly to your HVAC system. The most common system we install is the AirSCrubber by Aerus paired with an AprilAire filter.
These screens are small enough to catch microorganisms. Then, the system uses UV light to eradicate them. You can read more about these here and here. But, the purifier also has a blower motor that accounts for the extra resistance.
