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.

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.

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.

Cooling in Details

coolingExamining, for the last time this month, the heating and cooling system that you have at home or at work, we know that the evaporator plays a large role in the St Louis Cooling near Ladue.  The evaporator coil actually works similarly to a car’s radiator to produce cool air, which is then circulated through the ductwork.

Next, we come upon the condensing unit of your cooling system in St Louis near Ladue. We know from a recent article we skimmed on HVAC, that the following is true, “The condensing unit is connected to the evaporator coil. This unit is installed by HVAC contractors on the outside of your home and filled with refrigerant gas. 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.”

Let us not overlook the refrigerant lines in a cooling system in St Louis near Ladue MO.  These specific refrigerant lines carry a refrigerant substance to the condensing unit which has been vaporized in the form of a gas.  It then gets returned in liquid form back to the evaporator coils. These “lines” are actually narrow tubes manufactured from a durable heat- and cold-resistant metal such as copper or aluminum.  Finally, we have to glance at ductwork and vents.  The ductwork is in reference to the system of ducts whose job is to transport air warmed or cooled by the system to the various areas of your home. Ducts are commonly made of lightweight aluminum.  According to your St Louis Cooling Repair near Ladue, they may also be manufactured from steel, flexible plastic, polyurethane, fiberglass, or fabric.

 

Different Components of Your Cooling System

heat exchangerFrom the world of heating and cooling in St Louis near Wentzville, there exist many different components, all of which are designed to serve a purpose and many of which fly under the radar of our complete understanding.  We set out to change that, one element at a time and we are now looking at the refrigerant lines in your St Louis cooling near Wentzville MO. “The refrigerant lines carry a refrigerant substance to the condensing unit vaporized in the form of a gas, and return it to the evaporator coil in liquid form. These ‘lines’ are actually narrow tubes manufactured from a durable heat- and cold-resistant metal such as copper or aluminum.”

Now we arrive at the ductwork. In an HVAC system in St Louis, the ductwork refers to the system of ducts that transports air warmed or cooled by the system to the various areas of your home. These ducts are commonly made of lightweight aluminum. However, they may also be manufactured from steel, flexible plastic, polyurethane, fiberglass, or fabric.  Then we see the vents in your heating and cooling system in St Louis MO.  These are typically rectangular outlets where heat or cool air is transferred from the duct system to the actual rooms and spaces to be heated and cooled.

Elaborating more completely on the vents, we see that the metal is “Made of high- and low-temperature safe metal, similar to the lines we discussed earlier within the HVAC system.  The vents are located on or near the ceiling and are usually fronted with angled slats (“vents”). “These vents direct the treated air downward to where people are using the room. Often they may be manually controlled or even closed, to control the amount of heating or cooling and the area of the room to which it will be directed.”

 

The Original Heating Installation Matter Down the Road

install of HVACTo clean or not to clean is the first question we delved into rather deeply in the previous handful of posts here, on behalf of your St Louis Cooling Service near Belleville IL.  We have determined that much of the answer lies in personal preference and mostly in individual heating and cooling system circumstances.  Let us assume that you do plan to pursue professional cleaning of your St Louis HVAC near Belleville IL.  “If you decide to have your heating and cooling system cleaned, it important to make sure the service provider agrees to clean all components of the system and is qualified to do so.”  We have found in our recent research that cleaning only some of the system is a waste of time as is replacing a full system without determining the source of the issue, assuming you are dealing with something bigger than dirt, such as unwanted creatures or mold.

In your heating and cooling system in St Louis, as it pertains to cleaning ducts, we find that this will refer to the cleaning of various heating and cooling system components of forced air systems, including the supply and return air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, condensate drain pans (drip pans), fan motor and fan housing, and the air handling unit housing.

Also, sometimes the need for an HVAC clean lies in the inappropriate installation and maintenance of your heating and cooling system in St Louis near Belleville IL.  “If not properly installed, maintained and operated, these components may become contaminated with particles of dust, pollen or other debris. If moisture is present, the potential for microbiological growth (e.g., mold) is increased and spores from such growth may be released into the home’s living space.”  Therefore, often times the aftercare of your system is directly related to the quality of the installation of your HVAC in the first place.  Look for someone recommended and qualified, such as your St Louis Cooling Service and Sales near Belleville IL when it comes time to purchase and install the original system or address a replacement HVAC.

 

 

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.

 

Air Pollution and HVAC Cleaning

cooling cleaningWhen it comes to your heating and cooling system in St Louis near Collinsville IL, we know that many of you are confused as to whether or not to clean you ductwork and, honestly, the answer is a bit up in the air, depending upon who you talk to.  “Air duct cleaning service providers may tell you that they need to apply chemical biocide to the inside of your ducts as a means to kill bacteria (germs) and fungi (mold) and prevent future biological growth.” They may also propose the application of a “sealant” to prevent dust and dirt particles from being released into the air or to seal air leaks. You should fully understand the pros and cons of permitting application of chemical biocides or sealants. While the targeted use of chemical biocides and sealants may be appropriate under specific circumstances, you will want to know what is best for you.

Let’s look now at exactly what constitutes air duct cleaning. Most people have been made aware that indoor air pollution is an issue of growing concern and increased visibility in the form of marketing and professional heating and cooling service in St Louis near Collinsville IL. “Many companies are marketing products and services intended to improve the quality of your indoor air. You have probably seen an advertisement, received a coupon in the mail, or been approached directly by a company offering to clean your air ducts as a means of improving your home’s indoor air quality.”  You may wish to contact your St Louis Cooling maintenance near Collinsville IL to find out more about what they and other companies are offering in the HVAC cleaning realm.

In the meantime, understand that price will vary based on things such as the size of the system to be cleaned, the accessibility of said heating and cooling sytem, the climate where your HVAC is located and operated and the level of contamination of your current heating and cooling system in St Louis MO.

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.
