The Importance of Ventilation in HVAC

ventilationWhen researching a variety of topics on behalf of your St Louis Heating Sales and Installation near St Charles, we ran across several in pursuit of more knowledge on the ventilation portion of the HVAC system.  As a result, we have decided to further discuss it here.  “The purpose of mechanical heating, ventilation, and air conditioning (HVAC) systems is to provide air at comfortable temperature and humidity levels, clear of harmful pollutants such as mold, mildew, and other bacteria. Although heating and air conditioning systems are relatively standard operations, complex ventilation processes can often determine the quality of our indoor air.”

Once upon a time, ventilation was simply open windows, adding a fan would increase your ventilation’s effectiveness, but fell short in many heating and cooling scenarios, nonetheless.  In today’s day and age, modern buildings typically use a combination of mechanical ventilation processes, resulting in the supply and removal of air from inside a building or home. “Ventilation processes bring in the air from outside, condition and mix the outdoor air with a portion of the indoor air, distribute the mixed air throughout your home or building, and send a portion of the indoor air back outside.

It is our experience in the St Louis Heating Repair near St Charles that when one or more of these ventilation processes fails, indoor air quality can and will deteriorate. For this reason, your ventilation is one of the most important aspects to Heating and Cooling near St Charles MO.  “Proper design, operation, and maintenance of the ventilation system is critical to providing indoor air that is free of harmful pollutants.”  Whole HVAC systems in place in your St Charles home can also be large contributors to issues with indoor air quality, so should be properly maintained every year as well.  Your St Louis Heating Maintenance near St Charles offers these services to those in your area.

Heating in Primitive Homes

cavemanIn an effort to bring you the latest and most interesting information regarding historical data and techniques surrounding heating in the world, long before we had the modern day technology, we are starting at 1,900,000 BC when humans began using fire to cook food. According to our St Louis Heating sales and repair research, the following is true, “Archaeologists believe that humans may have used fire in a controlled fashion around this time, but evidence of such only dates back to about 100,000 years ago. In the oldest arrangements discovered, humans created central fires in homes that had openings in the roof for smoke to escape.”

We now look on behalf of your St Louis Heating Sales near Wentzville MO, that around 42000 BC, the following is true, “Neanderthals in the modern day Ukraine build hearths using mammoth bones.”  Then in 7500 to 5700 BC: Neolithic Çatalhöyük settlements in Turkey use open hearths in homes and buildings, according to the St Louis Heating sales near Wentzville MO.  Then, Romanian settlers use braziers to heat homes and this is a huge stride in the world of heating in St Louis near Wentzville and also a very interesting turn in history.

Moving right along, in 2500 BC, we find the Greeks in ancient Rome developing central heating using radiant heat. “In the excavated Temple of Ephesus, archaeologists discovered flues in the ground that circulated heat produced by a fire.” There is also evidence that the Roman Empire used central heating systems, believe it or not, as some buildings, baths, and upper-class homes had hypocaust furnaces that heated empty spaces under floors that connected to pipes in the walls—the first form of radiant heating. Different cultures also developed similar furnaces, which became more efficient with time as we read in our history research for the St Louis Heating Repair near Wentzville.  Stay tuned for more information regarding the timeline of Heating in St Louis.

The History of Primitive Heating Techniques

fireIn the next three posts, on behalf of your St Louis Heating Installation near Edwardsville IL, we plan to cover some of the old school methods of heating, as well as travel you into the modern day options that currently exist on the Heating and Cooling market in St Louis near Edwardsville.  We all know that one of the most basic human needs is warmth. Without it, bodies cannot thrive.  In today’s day and age, thanks to advances in technology and home heating systems, achieving comfortable temperatures is as simple as flipping a switch. Turn back the clock with us at your St Louis Heating Sales near Edwardsville, and we can see what things were like back in the old days.

For starters, it is totally true that ancient civilizations didn’t have it as simple. Some of how you were warmed was based on where you ended up living, according to our research on behalf of your St Louis Heating Sales.  “For those who migrated to the world’s cooler regions, the sun did not provide enough warmth to live.”

Humans, historically have a very strong intellect when it comes to doing what they need instinctively.  “Through sheer ingenuity, humankind’s early ancestors learned how to harness the power of fire, as well as use the Earth and sun to heat their homes and kingdoms. Using the principles that these forefathers established, humans have developed heating systems that keep families comfortable through even the most frigid winters.”  In the next two posts on behalf of your Heating sales and service near Edwardsville, we will cover the timeline of home heating systems.

Many Facets of HVAC

miscWhen it comes to the heating process that is involved within an HVAC system, and more specifically, the furnace of a St Louis heating system near Ladue MO, there are several key factors to consider and about which to learn.  “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 dive, now, further into the capillaries of each of these main points beginning with the heat exchanger, on behalf of your St Louis Heating Sales near Ladue MO.  “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 heat exchanger pulls in cool air, heats it, and circulates the resulting heated air via your ducts and out through the vents.”

Next, we take a closer and more in-depth look at the evaporator coil which has an opposite role to the heat exchanger.  The evaporator coil, according to the experts from your Heating and Cooling repair and sales near Ladue in St Louis MO, acts to cool the air when your thermostat is set to lower temperatures in summertime. Working in a fashion that is somewhat familiar to an automobile’s radiator in order to produce cool air that can be circulated effectively through the ductwork, an evaporator coil is located in a metal enclosure on the furnace’s exterior, to the top or side.  Evaporators correspond directly to condensers both in the case of heating and cooling in St Louis and also in the area of refrigeration.  Stay tuned for more information from this source in future posts on the specifics surrounding the condenser and other facets of HVAC.

The HVAC Breakdown and Discussion

chatThis is the research upon which we have focused lately and will gladly pass your way on behalf of your Heating repair and service in St Louis near St Charles MO, “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. Learn the facts about essential components of your HVAC system and find out the role each plays in keeping your household — and its members — warm in winter and cool in summer.”  So, here we go, filling you in on the above matters regarding your home, office or business and its heating and cooling system.

Let us begin with the thermostat. The thermostat is usually the most visible part of anyone’s HVAC system at home or in a commercial business environment. It is typically set on an obvious and prominent, easily accessible wall, it may be either programmed in advance or set manually to keep the home or business at a desired temperature. The way it works is by sensing temperatures.  “When the ambient temperature becomes too cold or too hot, the thermostat will trigger the heat exchanger or the evaporator coil-condensing unit combo to begin circulating warmed or cooled air as needed.”

Moving on in this St Louis heating and cooling sales and service tutorial, we come upon the actual furnace. Sort of central to the whole shebang, the furnace is the aspect to understand with the most clarity if you want to be in touch with your HVAC system in St Louis. “The furnace is the key component of your HVAC system. It’s also the largest, requiring substantial space — typically in the cellar, your finished basement, the attic, or a special closet designed for that purpose. Its function is to heat a supply of air which is to be distributed to various rooms of your home via the HVAC.”  Learn more about the heating process in the next post here on behalf of your St Louis HVAC near St Charles MO.

 

Heating Elements in HVAC

heat exchangerLooking 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.

 

Some Will Clean HVAC for the Sake of Clean

HVACHeaded back around the bend, we are still looking closely at the HVAC systems of today, and more specifically, whether or not we need to concern ourselves with having them cleaned by heating and cooling service in St Louis near Webster Groves MO.  The answer seems to lie, like so many other questions, in the details of your situation. “Some research suggests that cleaning heating and cooling system components (e.g., cooling coils, fans and heat exchangers) may improve the efficiency of your system, resulting in a longer operating life, as well as some energy and maintenance cost savings. However, little evidence exists that cleaning only the ducts will improve the efficiency of the system.”  So, it could be more of a question of how much of your heating and cooling system you address in the cleaning process, or just how thorough you ask them to be when you call your St Louis heating and cooling installation near Webster Groves for your next HVAC service.

Many people will agree that the debate is pointless, in fact you may consider having your air ducts cleaned simply because it seems logical that air ducts will get dirty over time and should be occasionally cleaned. “Provided that the cleaning is done properly, no evidence suggests that such cleaning would be detrimental. EPA does not recommend that the air ducts be cleaned routinely, but only as needed.”  Also true and found in our recent research on behalf of your St Louis heating service near Webster Groves, is that the EPA does, however, recommend that if you have a fuel burning furnace, stove or fireplace, they be inspected for proper functioning and serviced before each heating season to protect against carbon monoxide poisoning.

If you do decide to have your air ducts cleaned, take the same consumer precautions you normally would in assessing the service provider’s competence and reliability.  You may wish to only pursue those businesses highly recommended to you, such as your St Louis Heating Sales and Service near Webster Groves.

 

Heating and Cooling Replacement vs Cleaning

heating cleaningWe are now broaching the second post within the same subject of HVAC systems and whether or not to have them cleaned.  We ended the previous post on mold scenarios and how, obviously, if you have mold in your HVAC in St Louis near Fenton, then you need to consult an HVAC service company in St Louis in order to have it cleaned or to have someone referred to you for cleaning.

A few final mold pointers for you, found online, are as follows, “If you have insulated air ducts and the insulation gets wet or moldy it cannot be effectively cleaned and should be removed and replaced.  If the conditions causing the mold growth in the first place are not corrected, mold growth will recur.”  Now, we will move onto other scenarios by which it is wise to have your heating and cooling in St Louis near Fenton cleaned by professionals.  Say, for example, your ducts are infested with rodents, insects or other vermin.  You will definitely want to consult heating and cooling services in St Louis if that describes your situation.

A third and less unusual situation will involve your St Louis Heating and Cooling Ducts being clogged with excessive amounts of dust and debris and/or particles (more than the average system).  This describes an HVAC that definitely needs heating and cooling service near Fenton to be cleaned thoroughly for optimum performance.  “If any of the conditions identified above exists, it usually suggests one or more underlying causes. Prior to any cleaning, retrofitting, or replacing of your ducts, the cause or causes must be corrected or else the problem will likely recur.”  So, don’t let someone talk you into full replacement from the start as this will not necessarily address the cause of your predicament and will likely get you back in the same boat.

Commercial Warm Air Heating

heating equipmentIn the heating and cooling world of which we are a part, we try to bring to you some of the latest information on behalf of your Heating Installation in St Louis near O Fallon MO.  Some of the most intriguing data comes from subjects that are somewhat fundamental, yet mysterious to most, such as how heating systems actually operate. Today, we will talk about the two main types of heating systems:  warm air and radiant heating in St Louis near O Fallon.

Warm air heating is classified as the first type of heating system and makes use of fan to draw air across a heat exchanger, which increases the temperature of the air and distributes it evenly throughout an area or space. These are ideal for environments requiring constant temperature.  The process involved here is for a warm air heating commercial system in St Louis and starts from a gas or oil fired burner as the initial source of warm air.  Then, hot water circulates throughout the heat exchanger or the electric element.

How are these particular heaters in St Louis installed?  Well, they can be situated by suspending them above the space being heated or mounted on the walls or even on the floor.  For those of you heating a commercial space who need to resort to the floor installation, the following may be important to note, “The floor standing models may use outlets to direct the warm air to specific areas or they can be directed to a duct work system to distribute the warm air to a bigger area. The choice will depend on the floor area or layout of the space.”  There is more to discuss here, regarding the warm air heating process and specifics on how these particular heaters work.  Stay tuned for future posts on the subject on behalf of your St Louis Heating Installation near O Fallon MO.

Radiant Heating in Commercial Environments

radiantWe recently set out to discover the types and ways in which it is best to heat a commercial space in St Louis near Belleville IL.  We found that there are two main styles of heating and that after you understand the area that you are attempting to heat or cool, you will likely be able to better decide which way works best for the space in question.

The first type, which we went into pretty good details over in the previous post here on behalf of your St Louis Heating and Cooling installation and sales near Belleville, is referred to as warm air heating.  Ideal for areas that require a more constant temperature, these commercial heating set ups are usually started with a gas or oil fired burner as the source of heat, then hot water is typically circulated through the heat exchanger or an electric element from there.  There are floor models or those that can be suspended above the space in being heated by your St Louis Heating Service near Belleville.

“The floor standing models may use outlets to direct the warm air to specific areas or they can be directed to a duct work system to distribute the warm air to a bigger area. The choice will depend on the floor area or layout of the space.”  Radiant heating is yet the other type of heating in St Louis near Belleville IL and it is a popular way to heat commercial space as well.  Typically provided by radiant tubes that are placed in built-in duct work throughout the roof, the radiant plaque heaters are sometimes used there instead.  In either case though, according to our St Louis Heating sales near Belleville IL, the heat energy is emitted in the form of infrared radiation from the hot surfaces of the heaters. The infrared radiation warms the people or occupants and other objects exposed to it.
