Actual air studies by a reputable international organization, such as NAIMA, has conclusively proven that this in fact occurs in a ventilation system, which of coarse should be a no brainer because if particulate matter was merely stuck to the sidewalls of ductwork and did not in fact circulate, then mechanical engineers would
have never invented a furnace filter. How many HVAC service technicians have instructed you to never use a furnace filter?Probably, not too many, right?That is because it has been known for several decades that dirt, dust and debris will always circulate in a forced air ventilation system. Fortunately, most people are not completely unaware of this problem and have realized that occasional HVAC system cleaning can produce very good indoor air quality results when performed thoroughly and correctly. A raging debate between various companies world wide tries to advertise and endorse their methods of cleaning to convince a consumer and potential customer that their method of cleaning is superior. Rather than writing a very obvious slanted article, I realized that simply stating what the advantages and disadvantages of each cleaning method is, would allow the consumer or potential customer to decide for themselves as to which cleaning method would best serve them. Yes, I can admit that every cleaning method has a clear advantage and disadvantage. Although I would love to make every consumer and or potential customer our customer, the reality is that many factors affect where a consumer or potential customer turns to for their indoor air quality needs. The power vacuum/air sweep method involves a powerful large diameter vacuum hose generally ranging in diameter from 8” 12” that moves anywhere from 3000 CFM – 26,000 CFM cubic feet per minute of negative air draw depending on the type of power vacuum machinery being used. Typically speaking, having power vacuum
machines that moves anymore that 10,000 CFM is foolish, considering the fact that all ductwork is rated for a set amount of CFM based on the size of the ductwork through external static pressure ratings, velocity and ambience. I do have to admit that the more power a vacuum has, the cooler it is to witness, though. The power vacuum hose is typically installed into the ductwork via a circle cut out which allows for the power vacuum to put the entire side of the ductwork under a complete and sound vacuum draw.

It can also feel a tad disjointed compared to the Nest Secure, considering the keypad and the base station are two separate units, and the Nest Guard seamlessly combines the two and includes Google Assistant. If not placed somewhere discreet, the motion detectors are obtrusive and
look like a child’s night light. The contact
sensors also only detect for opening and closing doors and windows, whereas the Nest Detects detect for door and window openings but also include motion sensors. The basic Nest Secure package comes with a hub — the Guard — two key fobs Nest Tags that allow you to check in and out of your system, and two sets of motion detecting sensors you can attach to doors or windows Nest Detects. At 3. 7 inches in diameter and 2.

While we chalked most of this up to the fact that ADT has several million more customers than its competitors, our tester began his call with low expectations. He was pleasantly surprised, saying, “My needs drove the conversation. And once I finally had the quote, he explained the purpose behind each device I was receiving and what the installation might entail. He took extra time to help me weigh whether I needed home automation or not — and I’m almost positive it wasn’t scripted. ”Abode provides one of the most robust displays of third party
integrations in this lineup. The company offers a decent amount of its own proprietary devices, but you’re certainly not limited to Abode specific products alone. An Abode system can communicate with a slew of Z Wave and
Zigbee compatible smart lights and locks, light switches and dimmers, Nest products, IFTTT commands, and, of course, Amazon Alexa and Google Assistant. Put simply: If you want the freedom to lock/unlock your door or turn on/off the lights all in one place from the Abode app, this system is definitely worth a look. Installing the Ring Alarm took less than twenty minutes and was a complete breeze. We didn’t encounter any issues with device connectivity or placement, because, frankly, Ring tells you exactly where to install everything and how to do it on the app. You’ll start by connecting your WiFi to the base station via the Ring app — from there, Ring instructs you to pull the plastic tabs off the backs of the contact sensors and motion detectors, which automatically activates the products for use.
