Why Is Pollen A Problem?

It’s Spring! The grass is green, the trees are leafy, and the flowers are quite pretty. This however, brings with it an air quality problem: pollen. The HVAC solution to pollen is to maintain positive pressure in the building, good filtration, and implement some good cleaning practices. That however, is not what we’re talking about today. We’re talking about the science of pollen and why we have pollen allergies, because few HVAC Blogs look at this type of science, but we do. Plant Reproduction Most complex life on Earth needs two organisms to reproduce. You have two parents, your dog had two parents, and the tree in your front yard, probably had two parents. The thing is though, trees and flowers can’t walk up to each other to reproduce, they’re just static-things that shift in the breeze. Something has to move genetic material from one plant to the other. Pollen is how plants reproduce. They’re hardy cells that get carried off into the wind in such vast quantities that they’re all but guaranteed to swarm a compatible plant. These cells contain that tree’s genetic material and they’re designed to mix with another plant to produce seeds that will eventually grow into another plant. This is an ongoing process, but it’s worse in the Spring when plants are bursting back to life after a long, dormant winter. Varying weather conditions will cause days with more or less pollen. After a period […]

Upgrade Season

It is almost comfortable outside. Mother Nature hasn’t yet committed to the warm 70s, but we have a good few days of 50s and 60s ahead. We’re going to have about two months where our HVAC systems can sit nearly idle, untouched and unneeded. This is your ideal corridor for major maintenance and installing new systems altogether. Depending on the scale of your facility, you may well need it. Perfect Weather From a comfort-perspective, the very beginning of Spring is an ideal time. We’re well acclimated to cool weather and the slow move into the low sixties and seventies means we can be comfortable without any HVAC equipment. We can open the windows for a few days and no one is going to be inconvenienced by it. We can shut down the building’s plumbing and install temporary accommodations outdoors and it won’t be painful or disruptive to your employees for a few days. This rare window is different from the fall. Being cold is inherently uncomfortable and harder to compensate for than being too warm going from winter into spring. In the fall, if you get a very cold day, there’s little you can do to heat the building without buying every space heater in the city. In the spring if you get a warm day, tell your employees it’s Casual Friday all week, shorts and t-shirts approved. Open a window or leave the front doors open. The shifting weather […]

Spring HVAC Prep

The weather is finally warming up. For the first time in months I left the office and didn’t have to worry about getting frostbite on my spleen. We hit 74 degrees last Friday here in Philly, I took a bike ride and came back looking like a drowned rat, but it was warm. It’s only 36 Fahrenheit today, but Spring is on the way. The coming warmth means we should start talking about your maintenance schedules. Do Your Chores It’s vital to inspect, clean, and maintain your HVAC equipment. It’s going to cost you if you don’t. You should inspect your entire HVAC System at least twice a year: once before spring, and again before fall/winter. These little maintenance checks will keep you, your employees, your customers, and any other guests comfortable year round. As the weather warms up, you will begin to dial back your reliance on your building’s heating system. This is an ideal time to find a warm day, shut it down, and have your contractor do some cleaning and inspections. Most burners will leave some measure of dirt/soot in the combustion chamber for you to clean up. Leaving this there will reduce your system’s efficiency and may eventually clog up the heat exchanger altogether. From a maintenance perspective, this is an ideal time to check that the ignition system is in good shape and doesn’t require any adjustment or replacement. Things like the spark rod in […]

Winter is Coming – Prepare Yourself

Today we start to change gears and prepare for the change of seasons. Summer is coming to a close. We’re already seeing temperatures drop around Philly, with our highs falling from the 90s into the 80s. It’ll be a cooler, more comfortable week this week, with temperatures well on their way to the chilly fall norms. Now is about the time to make sure your heating system is ready for a long, busy season.   Why Check the Heater? For most people in the northern most parts of the US and elsewhere in the world, our heating systems have been dormant all summer long. You could have old, gross filters still in the system or discover a mouse has eaten the thermostat wires. There’s also that always looming spectre of hardware failure, when an old part has finally gotten old enough to just give out. It’s warm now and your AC is still running, so you don’t need your heating system yet. Your contractor can have the system apart for a good few weeks, you can use cheaper, slower shipping, and suffer no ill effects for it. This is also a good time for simple, routine maintenance. You can take this opportunity to swap out your air filters, have your chimney cleaned, clean out the furnace, and so on. Different system designs accumulate differenent maintenance needs. Oil burners often need a good cleaning to remove soot, for example.   What […]
