HVAC Trends

trendsHeating, ventilation, and air conditioning is what makes up the HVAC industry and is a subject on which we find ourselves focused often in order to bring you the latest information.  “It’s something that you’ll find in buildings, homes, and even vehicles. We often take these needs for granted, wanting to turn on the heat when we’re cold or the A/C when we’re warm.”  There are trends within the industry that relate to St Louis HVAC near Clayton and these things must be followed in order to help keep a building altogether healthy from a heating and cooling perspective.

When it comes to trends, regulations cover a wide area of ever-changing guidelines.  “Regulations drive HVAC industry trends. In the northern US, furnaces must have a 90% efficiency rating, but in southern states, only an 80% efficiency rating is required.”  Your St Louis HVAC installation near Clayton knows that they must stay on top of regulation requirements.

“This means HVAC industry trends tend to be fueled by local and regional data instead of an overall set of trends. To discover what is in store for this industry, we must look at emerging technologies, integration, and how local regulations are evolving to get a picture of what to expect in the days and years to come.”  There is a smarter industry on the horizon when it comes to HVAC sales and repair in St Louis.  “Many within the HVAC industry are beginning to automate their sales and service processes, allowing them to cut their customer acquisition costs to keep pricing competitive.”  Using technology to their advantage is another way that HVAC in St Louis is trending in a way to keep up with other competitors and to maximize ability with less effort and cost.

HVAC Take Two

take twoIs your HVAC system a heat pump?  If so, we have information to share with you, on behalf of your St Louis HVAC Sales and Repair near Fenton MO.  The deal is that if your HVAC system is a heat pump, it won’t have a separate furnace. Dave Moody, an HVAC industry pro with Service Experts, explains, “A heat pump works like a regular air-conditioner in the summer, then essentially works in reverse in the winter, serving both cooling and heating purposes.” A heat-pump system will still have indoor and outdoor components.  You may wonder what they are, so read what we found out below in our St Louis HVAC sales research.

Outside the house you’ll find the compressor and condenser components of the central air-conditioner (or heat pump), which are mounted in a metal cabinet with a large fan, that is the typical set up for anyone with a St Louis HVAC near Fenton who possesses a heat pump in their home.  Also, there is a possibility for a slight variation of the above description. “One alternative to a split-system is called a ‘packaged’ system, in which all components are installed in a single unit outside the home, with ducts entering through the wall of the home. These units may be preferable for a homeowner who doesn’t want to waste space on the interior of their home with heating and cooling equipment.”

Many people learning, along with those of us researching to teach more, tend to overlook the V portion of HVAC installation in St Louis near Fenton MO.  Here is what one online expert says about it, “Not often addressed in most HVAC installations is the ‘V’ – ventilation. Most homes rely on infiltration, or air that seeps in through gaps and cracks in the home’s shell, for limited fresh air. Service Experts’ Moody says, ‘As indoor air quality (IAQ) is increasingly implicated as a big factor in human health problems, mechanical ventilation systems are becoming more commonplace.’  We plan to elaborate more on the ventilation portion of our HVAC itinerary in the near future here on behalf of your HVAC installation in St Louis MO near Fenton.

HVAC Take One

take oneWe like to bring you all the latest news in the world of HVAC on behalf of your St Louis HVAC sales and service near O’Fallon MO, but sometimes it is important to reevaluate the information you share and attempt to cover more of the basics for those in your audience who may be unaware.  So, today, we will look at the basics of St Louis MO HVAC and hopefully help our readers get on the same page before we start covering more advanced details in our future posts.

Most homes are heated and cooled through a central, whole-home, Heating, Ventilating, and Air-Conditioning system (HVAC). The HVAC may well be one of the most expensive and energy hungry systems in the home, so the more you know about your HVAC, the better off you will be, especially if you act on what you know. A well-informed homeowner will save money and have a healthier, more comfortable home indeed.

When you hear people refer to St Louis HVAC near O’Fallon as split, this is a real thing and is due to the following, “Central HVAC systems are often called ‘split’ systems because some of the components are installed inside the home and some of the components are installed outside a home. Inside your home, usually installed in the basement, attic, or a closet, you’ll find the furnace (oil, gas, or electric) and the evaporator portion of the air-conditioner. You’ll also find the blower (sometimes called an air handler), which serves both the furnace and the air-conditioner. Attached to the blower are ducts, which are tubes acting as pathways to deliver heated or cooled air to various rooms in the house.”  Furthermore, the AC (or heat pump)has a condenser/compressor involved in its functioning, according to your HVAC sales and service in St Louis and it is typically installed outside the home, while the furnace, the evaporator and the blower are installed inside the home’s St Louis HVAC near O’Fallon MO.

 

HVAC Components

lock and key“An efficient HVAC system is important to the comfort of your family throughout the seasons of the year, because this climate control device is responsible for Heating, Ventilating, and Air Conditioning your home.” On behalf of your HVAC in St Louis near Ladue MO, we will be scrutinizing the different elements of an HVAC system to learn more about how they tie into the whole system and what each of the essential components brings to the table.

We will start with the thermostat in your St Louis HVAC near Ladue. “The thermostat is usually the most visible part of your HVAC system. Set on a prominent, easily accessible wall, it may be either programmed in advance or set manually to keep the home at a desired temperature.” When the ambient temperature becomes too cold or too hot and fails to match that which is set on the wall, the thermostat will trigger the heat exchanger or the evaporator coil-condensing unit combo to begin circulating warmed or cooled air as needed in order to bring the house up to or down to the desired temperature.

Moving on to the furnace, we discover the key component of your HVAC in St Louis MO. It’s also the largest, and therefore requires the most space.  It is often times in the cellar, your finished basement, the attic, or a special closet designed for the purpose of housing your St Louis HVAC near Ladue.  Its function is to heat a supply of air which is to be distributed to various rooms of your home via the HVAC. “This heating process is accomplished using one of four possible heat sources — combustion (burning natural gas, oil, coal, or propane), electric resistance, heat pump, or solar energy collected on site.”  We will pick up next time, looking at the heat exchanger, along with the other components of your HVAC system in St Louis near Ladue MO.

Down the Halls of HVAC

hallsLooking at heating in St Louis near Sunset Hills, we realize that is has been some time since we perused the halls of an HVAC explanation, looking for new details to point out surrounding your system in St Louis.  So, today, we stumble upon the heat exchanger. “The heat exchanger is found inside your furnace unit’s housing. This component switches on when the furnace is activated by thermostat to produce warmer temperatures in winter.” The way it operates is to pull in cool air, then heat it and circulate it by way of your ducts and our through your vents.

The heat exchanger pulls in cool air, heats it, and circulates the resulting heated air via your ducts and out through the vents.  The evaporator coil is another important heating component to understand.  It has, basically, the opposite job of the heat exchanger and it acts to cool the air when the thermostat is set lower and cooler during the summer months.  “Located in a metal enclosure on the furnace’s exterior, to the top or side, the evaporator coil works similarly to an automobile radiator to produce cool air, which is then circulated through the ductwork.”

Now, we move onto the condensing unit of your heating and cooling system in St Louis near Sunset Hills.  Connected to the evaporator coil, the condensing unit is installed by HVAC contractors on the outside of your home and filled with refrigerant gas in order to properly operate. “When the refrigerant has been cooled to a liquid by heat exchange with the exterior air, the condensing unit pumps the liquid to the evaporator coil to be evaporated into a gas once more.”  This leads us to your refrigerant lines which carry the refrigerant substance to the condensing unit vaporized in the form of gas and return it to the evaporator coil in liquid form.  In order to be resistant to temperature, these lines are typically made of copper or aluminum.

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.

How Smart Technology Impacts HVAC

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.

Unique HVAC Solutions and Water Technology

air conditioningWe have just recently been settled in on the subject of higher efficiency HVAC options here in the US and other places globally on behalf of your Commercial HVAC Sales and Maintenance in St Louis near Ladue.  Today, we want to look at something called an On-Demand Hot Water Recirculator.  “A U.S.-based company out of Rhode Island has designed an ‘on command’ pump for a home’s water lines, which allows cool water to be circulated back into the water heater upon activation.”  We will also examine ice-powered air conditioning and a couple other new inventions in the HVAC community.

The purpose of this design is to minimize the waste that we all tend to add to in the water world in the name of proper water temperature.  “This product was engineered to be a solution to a major problem to which all of us contribute: Each year, the average home wastes 12,000 gallons of water just waiting for that water to warm up.” Recirculating this otherwise-wasted water back into the system is an eco-friendly solution that’s bound to play a huge part in future homes.

Ice-Powered Air Conditioning is next on the agenda on behalf of your HVAC in St Louis near Ladue.  Air conditioners seem to be prime systems for gaining improvement through minor and sometimes major adjustments.  For this reason, a California-based company has created an ice-powered A/C system called the Ice Bear. “The Ice Bear essentially works by freezing water in a tank overnight, so the ice can help cool a building the next day. So far, the design has been able to provide enough cooling for a building for up to six hours, after which, a conventional commercial air conditioner takes over.”  When it comes to this particular HVAC technology, it still has a ways to go.  But for now, it can work in 6 hour increments, which is definite progress.

 

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 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.
