Lightening and Your Heating and Cooling

Lightening and Your Heating and Cooling

lighteningFrom your Heating and Cooling Sales in St Louis near Ballwin MO, we bring you some of the less popular subject content along with the other more exciting discussions.  Today, it is the former of the two, as we discuss disasters in the HVAC world.  “Even though, you may be keenly concerned about your uprooted trees, windows, and roofing system, after you have experienced a natural disaster, your HVAC system could also be in jeopardy. Once the natural disaster passes and your electricity is restored, it is crucial that you become familiar with the ways that a storm or hurricane could damage or destroy your HVAC system.”  We will go through specific disasters now and how they affect your system.

Lightening is the first thing we stumbled upon in our recent research on behalf of your St Louis Heating and Cooling Repair near Ballwin MO.  And the truth is, when lightening does strike, it can adversely affect your air conditioning or cooling system since this relies on electricity in the home to function properly. “When the electricity is disrupted, it could cause issues to your air conditioning system. The additional power resulting from a lightning strike could flood the circuit breaker in your home.” It could even damage electronics and appliances. There is something you could do, however, preventatively.  It is highly recommended that you install a surge protector prior to any natural disaster. This can absorb most of the electricity before it can damage anything in your home, along with your heating and cooling system in St Louis. A surge protector is also important in saving your HVAC equipment.

We will continue this conversation in the next post as we cover the ins and outs of hail and how that, along with other natural disasters can and will take its toll on your HVAC system in ways that your St Louis heating and cooling maintenance can predict and handle.

 


 

Cooling Maintenance Needs

Cooling Maintenance Needs

cooling repairIf you are the owner of an HVAC system, and chances are good, as an adult, that you either are or will be in the near future, you need to be aware of some things related to the ventilation portion of the St Louis heating and cooling near Collinsville IL.  The ventilation portion of the gig is often times overlooked when it is one of the most important aspects of heating a cooling your space in St Louis.  In fact, the following quote was snagged from a research article and found in our reading on behalf of your St Louis Heating Repair near Collinsville, “Because HVAC systems can also contribute to problems with indoor air quality, it is important that HVAC systems be correctly maintained and checked for signs of poor ventilation. When systems go unchecked for long periods of time, they may become contaminated or clogged, reducing or eliminating the amount of airflow and circulating pollutants throughout your home or business.”

So, the name of the game, when it comes to the ventilation portion of your St Louis HVAC maintenance near Collinsville IL, is proper upkeep.  This can mean regular cleanings or inspections at the least, in order to avoid polluted, contaminated air and or to increase the airflow and save you money in the long run.

If you have a humidifier or dehumidifier attached to your St Louis Cooling system near Collinsville, then you have more to consider.  “Additionally, humidification and dehumidification systems should be kept clean to prevent the growth of damaging bacteria and fungi. If the water in the system’s cooling towers are not properly treated, harmful organisms such as mold and mildew can grow and spread into the HVAC ductwork and potentially lead to serious health issues.”  Luckily, if you have an HVAC repair place you can trust, such as your St Louis Cooling Maintenance near Collinsville, then you can always call on them for all of your heating and cooling maintenance needs.

HVAC Breakdown

HVAC Breakdown

nitty grittyMost homes, businesses and offices are heated and cooled through a central, whole-building, Heating, Ventilating, and Air-Conditioning system (HVAC). The HVAC may well be one of the most expensive and energy hungry systems in the home or office, so the more you know about your HVAC, the better. A well-informed homeowner or business owner will save money and have a healthier, more comfortable home or office, so we are here to help fill you in on some of the HVAC details on behalf of your Heating and Cooling Maintenance in St Louis near Fenton MO.

There are several components in which to consider in your St Louis heating and cooling system. 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.”  The more you know about the structure of your St Louis Heating and Cooling system, the more likely you are to handle things that come up, whether it be in a do-it-yourself fashion or through the help of a commercial HVAC company such as your St Louis Cooling sales and service near Fenton MO.

The air-conditioner’s (or heat pump’s) condenser/compressor unit is installed outside the home or office in all cases. The furnace, evaporator, and blower are installed inside the home or office in each scenario. You will not have a separate furnace for an HVAC with a heat pump, just FYI.  As we fully explain the components of HVAC in St Louis, you will want to stay tuned here for further details, both simple and complex.

 

Down the Halls of HVAC

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

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

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.

 

 

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.

High R-Value in Your Walk In Freezer

High R-Value in Your Walk In Freezer

walk in freezerIn our adventures today in an effort to continue our discussions on walk-in freezers for your list of necessary restaurant equipment, we come upon the area of composition encircling the prefabricated walk-in cooler as opposed to the custom made version of these pieces of restaurant equipment in St Louis near St Charles MO.  “At their simplest, a prefabricated walk-in cooler is just a large insulated box with a cooling system. The components can be summed up in a very short list: panels, floor, door, and refrigeration system.”  Now it is time to go into further details about the above mentioned components.

Basically sandwiches made of foam insulation and thin metal sheets, panels range in size from 3 1/2″ – 5″ thick and their primary function is to keep the walk-in at the correct temperature for storing your fresh or frozen foods. They are generally made using a 24 to 26 gauge galvanized steel, aluminum or aluminum-coated steel, painted steel, or stainless steel that is called the skin of the freezer itself in the St Louis Restaurant Equipment world. In an effort to maintain a professional and perhaps commercial look, panels also often have embossed patterns in the metal. This pattern can actually add to its strength and reduce the notability of wear and tear.

“Pressed inside the skin is dense insulating foam to ensure energy efficiency. Some options come with extruded polystyrene foam insulation but the most common insulating material is foamed-in polyurethane.”  A high-performing insulator, extruded polystyrene has great moisture resistance. When researching the walk-in freezer options on behalf of your St Louis Restaurant Equipment Sales and Service near St Charles, we found it described as the best material to retain R-value.  “While most materials break down and lose R-value over time, polystyrene retains its insulating ability longer. Polyurethane is also a great insulator; however it may not stand the test of time as well as other materials.”  You are recommended to look for high quality insulation materials with low thermal transference and high R-value when seeking a walk in freezer to add to your list of restaurant equipment in St Louis.

Elaborating Further on Heat Pumps and Central AC

Elaborating Further on Heat Pumps and Central AC

defineMoving onto the second phase of description we are planning on behalf of your St Louis Heating and Cooling installation near Fenton MO, we still have much to explain about your cooling system in your home.  Your air conditioner, to be precise, and though we told you the basics when it comes to the system and how it uses energy to remove actual heat from your space, unfortunately, it isn’t quite that simple.  The process gets quite a bit more complicated with all the controls and valves involved, its effect it rather amazing.  “An air conditioner takes heat from a cooler place and dumps it in a warmer place, seemingly working against the laws of physics. What drives the process, of course, is electricity — quite a lot of it, in fact.”

Our first type of cooling system to discuss, namely because it is the most common, are the central air conditioners and heat pumps designed to cool the entire house. “In each system, a large compressor unit located outside drives the process; an indoor coil filled with refrigerant cools air that is then distributed throughout the house via ducts.”  Heat pumps are then like central air conditioners with the exception of the cycle direction variations.   “Heat pumps are like central air conditioners, except that the cycle can be reversed and used for heating during the winter months.”  We will go into more details on behalf of your St Louis Heating and Cooling sales near Fenton, in regards to heat pumps below.

With a central air conditioner, the same duct system is used with a furnace for forced warm-air heating. In fact, the central air conditioner typically uses the furnace fan to distribute air to the ducts, so there is an overlap and therefore efficiency existent in the system by its simple nature.  Central air conditioners and air source heat pumps in their cooling mode of operation are rated according to their efficiency in the seasons.  We will break down these details in the next couple posts here, on behalf of your Heating sales in St Louis near Fenton MO.
