Why is There a Belt in the Furnace?

Is it weird that we use belt drives in furnaces? Belts aren’t necessarily known as the most durable or flame-resistant thing in the world. Why would we put a belt next to a roaring inferno? It’s 2018, why don’t we just bolt the motor straight to the fan, blower, or whatever it is we’re driving?   Gear Reduction Spinning blowers, fans, and other equipment requires a lot of mechanical power. At the same time, it can take more power to overcome the friction on a resting object, especially for heavier parts or equipment that’s not perfectly supported. There can be additional friction by such offset loads. Providing enough force to move this equipment requires bigger and bigger motors. Or does it? Physics is full of tricks. We can use a concept called Gear Reduction so that a smaller motor can get the job done. Instead of outputting a lot of power at once, we output less power, but more revolutions of the motor. For every 2 rotations of the motor, the blower might only spin once. This reduction requires the motor to spin faster to achieve the same result as a bigger motor, but it won’t need as much torque to do that work. The easiest way to see this concept in action is to look at a multi-speed bike. Your gears are different sizes to allow for different speeds. In low gear, it is incredibly easy to spin the […]

When to Replace Your AC System

No one wants to replace an entire system, whether it’s your entire HVAC set up, just a furnace, or your AC. It’s expensive, time consuming, inconvenient, and an all around headache. Our whole industry is setup around maintaining these systems as they age and break down. There is however, a point where you can’t keep a dead horse limping along anymore.   Signs of an Impending Upgrade There are two big considerations to determine when you’re better off replacing an entire HVAC system, over trying to salvage the hardware you have on hand. We use the Rust and Wear of the existing system, against the gains in Efficiency, Performance, and Features of a newer system. If your central air was installed two years ago, you have little wear to consider and little incentive to upgrade. Even a twenty year old system might be worth keeping if it runs without incident. There are however, cases for systems that are perhaps five to ten years old, in particularly rough environments, that have become worn, failure prone, and a real pan to use. Those tired old systems are ready to retire. Procure Inc’s own head salesman himself, Scott, just used our two-factor thought process to look at his 16 year old central air system and decide it’s time to upgrade. He put in a preventative $400 in small repairs, but there’s easily $4000 of parts and labor needed to keep everything running in […]

Maintaining Your Ducts

You’re literally throwing money away. Literally, hundreds of dollars are going up into thin air. How could you lose so much money? Inefficient, leaky, ducts. Every time your HVAC system runs, it’s pushing air through your ducts. Ideally, every bit of air that goes in, will come out a vent in your office, storage room, kitchen, or anywhere else you’re trying to heat or cool. Unfortunately, that probably isn’t the case.   The Leaking Problem Every HVAC system needs maintenance over time. The laws of physics make a pretty clear-cut case that nothing lasts forever. Everything experiences wear, tear, and degradation over time. Your ducts were hopefully sealed at installation, but it’s always possible the contractor skipped that step. In days long gone, saving energy was not the massive issue it is today. Even if the system was sealed, it probably has developed leaks if its more than a few years old. The leaks occur wherever two pieces of duct work are joined together. We use things like Galvanized Steel and Aluminum to make most duct working. These materials are lightweight, durable, and unlike copper, are not so easily soldered or welded into a perfect seal. Of course, they’re cheaper than copper and don’t necessarily need the time and expense of soldering to be sealed. Given that we can’t turn five pieces of ductwork into one air-tight stretch by design, you can see where the problems arise. The ducts have […]

How Do Transformers Work?

So, transformers are these really cool robots that turn into cars, trucks, jets and the like. They usually end up breaking a major city, there’s some explosions, and a lot of screaming going on. It’s all because of this big war of the robots going on..   JUST KIDDING! You really thought I was gonna talk about robots when we have Electrical Transformers to talk about? No, no, no. These things are just too cool to pass up. We use them EVERYWHERE. Seriously, if you live in 21st Century USA and use electronics, you have at least one transformer, but more likely, probably dozens to hundreds of them. You need them in your washer, drier, computers, cell phone chargers, TVs, and so much more. It’s amazing.   The Problem Everything in the world runs on electricity, but the details about that electricity are different for nearly every device. Your home most likely receives AC Power from your local provider. In the US, that’s 120 VAC at 60 Hertz. What’s a little weird is that we transmit AC power everywhere, near every device in your home is run with DC Power. That’s alternating current versus direct current. So, we’re sending the wrong kind of power to your home or business, which can’t directly power your devices. It gets worse. The voltages are all different too. The processor in your computer needs multiple voltages. Generally at most, 1.35 Volts, plus some others. […]
