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.

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.”

Keeping Your Refrigeration Healthy

refrigerationAlong the same lines as our previous post where we introduced the fact that restaurant equipment in St Louis, including and especially commercial refrigeration, has a bad and a worse time of breaking down, we will continue our discussion here in terms of the details surrounding such a disaster.  Form one online reputable source of restaurant equipment information, we gain the following two cents, “If you’ve been in the business for a while, you’ve certainly experienced the anxiety (even panic) that occurs when a critical refrigeration unit goes down during a busy dinner shift. You can lose thousands of dollars in wasted product and lost business in a very short period of time. Not to mention the repair bill, which can often cost you double if it happens at night or a weekend, which of course it will!”

Luckily, avoiding commercial refrigeration repair isn’t as impossible as it may seem as most breakdowns of commercial refrigeration equipment can be prevented with simple regular maintenance, such as what is offered at your Refrigeration Maintenance and Sales in St Louis near Fairview Heights IL. You’re probably aware that your heating and air conditioning equipment needs to be cleaned and inspected twice each year. But many restaurant owners don’t realize that their refrigeration equipment also needs to be maintained and cared for on a regular basis in order to continue to be reliable to your restaurant business in St Louis MO near Fairview Heights IL.

In the post upcoming, we will cover an actual list of things to take care of on a routine basis in order to keep your refrigeration in St Louis MO and other commercial restaurant equipment in top running condition in order to keep your business as healthy and profitable as it can be for as long as you see fit.

 

Restaurant Equipment and a Love Hate Relationship

commercial kitchenIt is our job to bring you the latest in information surrounding the restaurant equipment maintenance in St Louis near Kirkwood MO and all other applicable categories in the commercial restaurant equipment business.  We pride ourselves in doing our best to keep you informed and so we want to discuss, today, commercial refrigeration and how to best maintain its health and function for your St Louis Restaurant Equipment needs.

Say there is a big event hitting your town that involves local food and restaurants, or really even an ordinary weekend when you know your restaurant will be busy and the equipment in high demand.  If your commercial refrigeration equipment fails at the wrong time, you’ll be sending all those potential new customers home dissatisfied or worse. So, in advance of restaurant needs, we’ll be posting great tips and resources on how to keep your equipment (and your head) cool!  This is an important concept to avoiding disaster at the worst possible time for your restaurant business.

Refrigeration equipment is your best friend and can be your worst enemy, according to one source we found online when researching the subject of everyday commercial restaurant equipment in St Louis near Kirkwood and its daily health and general upkeep. “Anyone who manages a food service operation probably has a love-hate relationship with refrigeration equipment. On one hand, they help you serve fresh and appealing fare. Without your coolers, chillers and walk in freezers, you’d be serving lukewarm drinks, wilted greens and melted ice cream. And that’s exactly the problem: when they break down, your business quickly comes to a screeching halt.”  Stay tuned for more information in the posts to follow from your St Louis Restaurant Equipment sales and service near Kirkwood on what to do to avoid the above scenario.

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.
