HVAC Certification in Today’s World

HVAC Certification in Today’s World

certifiedLooking to become certified in a growing field of high demand?  Have you ever stopped to think about pursuing a career in HVAC service near University City MO?  The schooling can be overwhelming these days given everyone’s busy life and schedule.  Some of the old methods of attending night classes or going back to school to receive an HVAC certificate might have seemed out of the question in the past and especially in today’s busy world. When researching the subject on behalf of your St Louis HVAC installation and sales, we recognized that the good news is: now you can study online to get certified. In some cases, it’s true that you can even take your exams online. We will discuss the ins and outs of getting certified in HVAC from the comfort of your own home, but for starters, it’s pretty amazing to know that you can.

“It is usually not required that technicians attend a trade school to receive a diploma in HVAC.”  Although often times a strong option for getting your HVAC education, there are also online options in today’s industry that will allow you to accomplish the same thing.  One reputable source online confirms, “While a local trade school is a strong option for getting your HVAC education there are also online classes and state HVAC certifications you can earn through a combination of hands-on experience and an examination process. At the end of these, you may receive a certificate or a diploma.”

The term “certification” can be confusing and mean different things, according to your HVAC installation in St Louis MO near University City.  It is sometimes used in regard to state requirements, depending upon where you live. When getting certified through your state you are getting a license to work and perform HVAC installations, maintenance, and repairs in the field, according to all we read on behalf of your St Louis HVAC sales and service.  Read our next post here for more details on how to proceed online.

Bottoming Cycles and Recycling in HVAC

Bottoming Cycles and Recycling in HVAC

HVACAs a follow-up to our previous posts regarding St Louis HVAC service near Overland and some of the heat recycling methods out there, we are going into more detail about bottoming cycles.  “Bottoming cycles are mostly used in industrial facilities in the chemical, paper, and primary metals sectors, as these industries often have high-temperature waste streams that are favorable for waste heat recovery. As much as 20-50 percent of the energy consumed in some industrial processes is ultimately lost through waste heat contained in streams of hot exhaust gas and liquids and through heat conduction, convection, and radiation from hot equipment surfaces and heated product streams.”

The goal, so to speak, is a simple one that applies to only some processes as others may not be safe enough when it comes to the waste they produce.   The overall energy efficiency of some industrial processes can be improved by capturing and reusing the waste heat, however, in situations where it makes sense from a safety and function point of view.  In our recent research on behalf of your St Louis HVAC installation near Overland MO, we discovered many facts surrounding the process to share here and in posts to follow.

“In some cases, such as industrial furnaces, efficiency improvements resulting from waste heat recovery can improve energy efficiency 10-50 percent. A study by the U.S. Department of Energy’s (DOE) Energy Efficiency and Renewable Energy office (EERE) identified research, development, and demonstration efforts to expand waste heat recovery practices in the U.S. industrial sector.”  In the aforementioned study, the waste streams analyzed showed that roughly 60 percent of unrecovered waste heat is low quality (i.e., temperatures below 450°F).  We will explore more regarding what this means as we further our research into heat recycling and HVAC in St Louis.

Bottoming Cycles in HVAC

Bottoming Cycles in HVAC

recycled HVACWe are moving along the HVAC train and looking for new and exciting information to share with you from your HVAC installation and service in St Louis near Chesterfield MO.  We found some interesting info on CHP or Combined heat and power systems and thought we ought to pass it alone.

“Combined heat and power (CHP) systems are being used by a wide range of applications to reduce the overall energy intensity of industrial systems. There are two types of CHP, depending on whether the system produces power first, then heat, or heat first, then power.”  According to your HVAC sales in St Louis, the topping cycles involve hot exhaust of an electricity generator.  Something like a natural gas turbine or reciprocating engine, is used to provide process heat, hot water, or space heating for the site. “According to preliminary 2015 data, topping cycles are used by 89 percent of total CHP capacity.” In bottoming cycles, also referred to as waste heat to power, wasted heat from a furnace or other high-temperature industrial processes is recovered and used for power production, which is also found to be noteworthy in our recent research as this is a form of energy recycling.

According to our HVAC sales St Louis near Chesterfield and the research recently done online, the bottoming cycles typically use waste heat boilers or steam turbine systems. “Ongoing research, development, and deployment efforts are focused on these systems as a way to reduce wasted heat and increase industrial energy efficiency.”  From an HVAC perspective, bottoming cycles are most times being applied in industrial facilities in chemical, paper, and primary metals sectors since these particular places often have high temp waste streams that are best dealt with using waste heat recovery.  All of this and more can be discussed as it applies to St Louis HVAC near Chesterfield and we will attempt to elaborate in future posts on this very subject.

On-Command Hot Water Recirculator

On-Command Hot Water Recirculator

water recirculatorThe world has been leaning green for the past several years now and HVAC is no exception.  “As recently as December 2013, President Obama said that the U.S. federal government must double its reliance on renewable energy by 2020, meaning that 20 percent of its energy supplies will need to come from renewable sources. The reliance on green energy has several benefits, including the ability to decrease the ‘environmental footprint’ on the plant, according to the U.S. EPA as well as to alleviate energy security issues while spurring economic growth within the U.S.”

We set out, on behalf of your St Louis HVAC sales and installation near Kirkwood, to deliver more info on just what that means from an HVAC perspective.  We know that the green trend means plenty of changes to the HVAC industry, but just exactly what, we were not sure. “Companies in the U.S. and worldwide are involved in research to create more energy-efficient traditional systems as well as new types of systems that run off alternative energies, such as geothermal or solar.”  We found a lot of information when researching for your St Louis HVAC sales near Kirkwood, but also realized that even more improved technologies can be expected in the future as companies work toward changing this country’s reliance on fossil fuels, which in the U.S. stands at 82 percent. “Only about 9 percent of the country’s energy supplies currently make use of renewable sources, which leaves plenty of room for change in HVAC systems.”

The on-command hot water recirculator is the one product we will describe today, in the HVAC green movement.  “This product, produced by Taco, Inc., out of Cranston, Rhode Island, saves money, energy and water while delivering hot water in a timely manner.” It involves installation of the “On Command” pump that attaches to the hot and cold water lines under a kitchen or bath fixture in a home, according to our HVAC research. “When activated, it allows the cool water being drained to circulate back to the water heater through the cold water line, allowing hot water to be delivered at any time 24 hours a day.”  The energy conservation is obvious here and kicks off our series in the St Louis HVAC installation near Kirkwood on HVAC renewable energy and green movements.

HVAC and Mold

HVAC and Mold

HVACWriting today on behalf of your HVAC installation service in St Louis near Jefferson County, we run straight into the in depth subject that begins with a simple question, “Should I have my air ducts cleaned?”  Knowledge about air duct cleaning is actually in its early stages, so a blanket recommendation cannot be offered as to whether you should have your air ducts in your home cleaned, believe it or not. The U.S. Environmental Protection Agency (EPA) urges you to read this document in it’s entirety as it provides important information on the subject and all came from reputable sources online.

According to a recent article found online, “Duct cleaning has never been shown to actually prevent health problems. Neither do studies conclusively demonstrate that particle (e.g., dust) levels in homes increase because of dirty air ducts. This is because much of the dirt in air ducts adheres to duct surfaces and does not necessarily enter the living space. It is important to keep in mind that dirty air ducts are only one of many possible sources of particles that are present in homes. Pollutants that enter the home both from outdoors and indoor activities such as cooking, cleaning, smoking, or just moving around can cause greater exposure to contaminants than dirty air ducts.”  However, there are definitely times when having your St Louis HVAC near Jefferson County cleaned, is highly recommended.  These are specific circumstances that are listed below.

There is substantial visible mold growth inside hard surface (e.g., sheet metal) ducts or on other components of your heating and cooling system. There are several important points to understand concerning mold detection in heating and cooling systems, also, so we have relayed below, on behalf of your St Louis HVAC sales near Jefferson County, what we learned in our research therein.  Many sections of your heating and cooling system may not be accessible for a visible inspection, so ask the service provider to show you any mold they say exists.  It is also recommended that you are aware that although a substance may look like mold, a positive determination of whether it is mold or not can be made only by an expert and may require laboratory analysis for final confirmation.  For about $50, some microbiology laboratories can tell you whether a sample sent to them on a clear strip of sticky household tape is mold or simply a substance that resembles it.

smart technologyToday, we will talk about smart homes and the future that they hold in our country and globally as well.  What does a smart home do and what does that mean for the forecast business and health of industries such as your St Louis HVAC near Wentzville MO?  “Everything is getting smarter these days. From the cars we drive to the televisions we watch, just about every piece of tech you can imagine has been outfitted with smart technology. It’s only natural, then, that our homes would be next.”

We set out to research the subject on behalf of your St Louis HVAC sales and service near Wentzville both for our own curiosities and for the interests of our followers.  We know that connected systems and phone apps already give us the ability to control our home’s lighting, HVAC systmes, security systems, surveillance, and entertainment at the push of a virtual button. It is safe to assume that these “smart” technologies will continue to evolve and become integrated into our homes, allowing us to control a home’s comfort levels down to the very last detail.

How does the above realization change the way we see and experience the world of HVAC installation and maintenance in St Louis near Wentzville MO?  “Since many of these innovations are already available on the market, this movement toward a smarter home has changed how HVAC engineers and designers approach the next big thing, which is good news for those of us who appreciate high-tech solutions.”  We will dive into further details here in the next post on HVAC future in things such as fully automated homes and even 3D printed air conditioners.

Thermally Driven AC

Thermally Driven AC

thermally drivenWe like to discuss all that is new and pertinent in the area of HVAC on behalf of St Louis American Services company who deals in HVAC sales and service near Edwardsville IL.  Some of the newest designs in the industry were covered last month. Today, we pursue more information to pass along to you.  “Another design that’s recently been implemented is thermally driven air conditioning. An Australian company named Chromasun has produced a low-cost alternative to traditional A/C units.”  This is yet to be a popular, widespread idea in technology, but interesting enough to include here, nonetheless.

Since it is not well known as of yet, it is also not available in the United States at this point.  The reviews and information we read online, however, on behalf of your St Louis HVAC installation, says it should not be long before this is not the case.  “It isn’t a widespread technology yet, and it will likely be several years before this kind of design becomes widely available in the United States. However, thermally driven air conditioning is a system that uses solar energy and is supplemented by natural gas, making it a highly efficient and effective system.”

With a double chiller such as the one is has, this particular design provides more cooling capabilities than any other system out there today.  “In fact, the double-chiller design provides more cooling capabilities than any other system so far, and it eliminates electricity costs altogether.”  This is one innovation in St Louis HVAC near Edwardsville that we recommend you keep your eyes on and plan to see more of in the near future.  In our upcoming posts, we will continue to discuss interesting options in HVAC similar to this thermally driven one.

Heat Pump Particulars in HVAC

Heat Pump Particulars in HVAC

heat pumpWe enjoy the efforts we put forth on behalf of your HVAC installation and repair in St Louis near Overland MO.  One of the best aspects of this job is to learn more about interesting topics and pass along what we discover to others.  Today, we are looking closer and the H in HVAC, which as most of you probably know, stands for heating.  Heat pump seemed interesting, so we first researched the details surrounding those.

There are two main types of heat pumps used in residential and commercial applications: air-source heat pumps (by far the most common) and ground-source (or geothermal) heat pumps. Did you know that a heat pump works like an air conditioner in the cooling cycle?  Then, when it is in the heating cycle, it simply does the reverse, working to cool the outside while venting heat to the inside. A major difference in the two mentioned above, was found during our research on behalf of your HVAC sales in St Louis near Overland, as follows, “Ground-source heat pumps transfer heat through earth or water, whereas air-source heat pumps do so via air. Because heat pumps simply move heat around rather than creating heat, they can be a very efficient method of space conditioning, especially in moderate climates.”

What lets us know the efficacy of a heat pump?  Well, this would be best measured in efficiency compared to yield.  “Heat pump efficiency is rated using two metrics: SEER (Seasonal Energy Efficiency Ratio) is used to rate the performance when the unit is acting as an air conditioner; HSPF (Heating Seasonal Performance Factor) is used to rate the performance when the unit is in heating mode.” In our research, we learned, on behalf of your St Louis HVAC sales, that there is much to be known about efficiency and many ways to dive deeper online.  For now, the above rating system is all we uncovered for time’s sake.  Stay tuned to this site for more posts on heat pumps and more discussion about their efficiency and other surrounding details.
