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.

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.”

 

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.

Cooling Technology and Movement Activation

motionIn the world of HVAC, we continue to have so much to report and read about.  The latest and greatest innovations continue to sift through the heating and cooling world and make our job reporting the latest news to you pretty fun and rarely ever dull.  One specific and somewhat revolutionary HVAC technologie that could change how we heat and cool our homes as we know it was found in our recent research on behalf of your heating and cooling in St Louis near Jefferson County MO. Many of these HVAC technologies are still on the drawing board, but there are some you can take advantage of now to boost your home’s comfort levels, according to all that we read.

Movement-Activated Air Conditioning was one thing we encountered in our research on behalf of your cooling specialists in St Louis and it has originated from engineers at MIT who have come up with a new air conditioning design that utilizes sensors along aluminum rods hung from the ceiling. Movement then activates these sensors. In other words, the air conditioner only kicks on when people are present.  That may be one of the most efficient cooling set-ups we have seen to date.

“A motion-activated system seems like such a simple, ingenious idea that it’s almost baffling it hasn’t been tried before now. However, this kind of prototype is just one example of how future HVAC systems are going to be more compact and portable, helping to reduce both energy and utility costs.”  Technology is amazing whether it is in the works or already in play in homes and offices and their existing cooling in St Louis near Jefferson County.  Either way, you need to stay on top of the latest in technology in order to find the best cooling system to fit your needs.

Not All Furnaces Are Created Equal

efficientIn an effort to finalize and summarize our recent series of posts on behalf of your St Louis Heating and Cooling installation and sales near Fenton MO, we are here today to say that of all the ways in which you can stay abreast of technology that will save you money in the HVAC world, the one way, besides the last money saving technology is to make sure you understand not all systems are created equally.

There are some systems that are much better than others at running efficiently.  Here is what one set of writers has to say on the subject in an article we found on behalf of our research being done for your St Louis Heating and Cooling sales near Fenton, “Not all furnaces and air conditioners are created equally. Just like different cars have different gas mileage, different HVAC systems use different amounts of energy to heat or cool a home.”

You may be interested in knowing that heating efficiency is measured by the Annual Fuel Utilization Efficiency rating (AFUE). It measures the amount of energy that is used by your furnace that is actually turned into heat. For example, an AFUE of 80 percent means that 80 percent of the energy a furnace uses is turned into heat and 20 percent of the energy is wasted, so obviously, the higher this number, the better.  If you buy a modern day furnace, or have done so in the recent past, then you should know that for furnaces manufactured after September 2015, the Department of Energy mandated a minimum AFUE of between 80 to 84 depending on the fuel type and whether the furnace is designed for a mobile home or permanent structure.  Beyond that, the numbers have to be displayed clearly on the package.  So, you likely have a more efficient furnace if it was purchased in the recent past.

Variable Speed Blowers Offer Cooling Efficiency

blowerBesides smart thermostats, which we have been discussing lately on behalf of your Heating and Cooling sales and installation near Edwardsville IL, we also know of many other cost saving elements available for consideration in your HVAC systems at home and at work.  Variable speed blowers is another aspect of HVAC technology that is well worth considering that will also save you money.

“One of the most common reasons people crank up their thermostats and let their energy bills rise is because they feel hot or cold when the HVAC system shuts off between cooling or heating cycles. Variable speed blowers help eliminate these temperature swings.”  A variable speed blower can help solve this problem by running at a much slower speed in the moments when the temperature has been met, in this way helping to maintain the heating or cooling temp desired for your comfort.

Here is how one article puts it online to help describe what a variable speed blower will offer you on behalf of your St Louis Cooling Sales near Edwardsville IL, “Instead of simply turning on and off, a variable speed blower runs at high speed when the home’s temperature needs to be changed and then slows down to a holding speed once the desired temperature is reached. This allows the thermostat to be set at a lower level and saves energy even though the overall running time may be longer.”  We began our discussions covering the point that so many of us sit on the edge of our seats, waiting for the arrival of the latest technology in the toy department of our electronics stores.  If it is a gadget of some sort, then it gains all sorts of attention, we then progressed into discussions about technology that saves, rather than costs you money.  Then we transitioned on behalf of your St Louis Cooling installation near Edwardsville, to cover the specifics of smart thermostats and variable speed blowers.  We will finish our series in the next post on efficiency that has been improved in the St Louis HVAC industry.

Ductless HVAC Details

HVACDid you know that in the world of HVAC there exist many different types of systems?  That’s right, today we will talk about the ductless St Louis HVAC near Ballwin MO and some of the reasons for an increase in popularity when it comes to HVAC systems such as these.  “There are plenty of good reasons why more commercial and residential customers are adopting ductless system solutions in place of old-tech, costly and bulky central split systems.”

Firstly, ductless systems offer major advantages and performance that is second to none when it comes to conditioning air faster, maintaining more accurate temperatures and reducing energy costs overall.  If we needed to sum up the advantages to ductless HVAC in St Louis using only one word, it would be flexibility.  “Ductless systems provide a scalable solution for additions, retrofit and renovation projects where complicated ductwork installation or re-routing is not feasible or where the central A/C system may not be able to reach effectively.”  This is especially applicable with the surge in popularity of tiny homes, retrofitted lofts and rowhouses where space is at a premium.  These ductless HVAC systems then become the most efficient option in order to meet the cooling needs of the space.

Efficiency is a key advantage of ductless systems also, so when you are in search of the best system for your St Louis HVAC near Ballwin, remember that the one in which you get the best cooling for the least amount of money is likely the one to pursue.  The following will describe in more detail, just why these types of St Louis HVAC can be the best in efficiency, “Ductless systems allow customers to customize their air conditioning needs to focus on certain rooms or zones used most, providing the ability to tailor temperatures to suit individual comfort levels. Because there is no ductwork required, efficiency is gained by not losing up to an estimated 40 percent of conditioned air through leaky, dirty ducts–also resulting in fresher air.”

Heating and Cooling Efficiency and Provable Facts

factsIn your St Louis Heating and Cooling systems near Belleville IL, whether they involve your office and industrial environments, or your everyday home unit and system, the importance of routine maintenance to these heating and cooling units cannot be denied.  Plenty of studies have been conducted and research proves that the neglected system is the inefficient system.  Also true is that the neglected system is the one more prone to breakdown and future need for repairs.

The above references heating and cooling studies have been cconducted and fall into two main categories:

– Analysis of failures in individual HVAC components and the energy savings possible by correcting those failures.

– Whole-system estimates based on interviews with HVAC maintenance experts. Energy Performance and HVAC Component Maintenance

One conclusion written by a testing group goes like this, “HVAC systems have over 100 components, and many common component performance issues degrade energy performance.” They provide results in the form of information that summarizes studies of the potential energy savings from good maintenance on chiller components with the greatest energy impacts.

There exists, also, a few studies in which the whole-building energy savings from HVAC system maintenance has been analyzed.   In each instance, the validity and importance of routine Heating and Cooling maintenance in St Louis near Belleville IL, has been confirmed.  Bigger buildings are covered in the work as well.  “The New Buildings Institute found that best practices in building maintenance and operations reduce energy use 10 to 20 percent across all climate zones in the United States. In contrast, poor maintenance practices can increase energy use by 30 to 60 percent.”  The list of citations and proof is rather in depth, but we will take pause there and just let the facts be known.  If optimum efficiency in an HVAC system is the desire, then routine maintenance is a must, not really an option, but a definite requirement.  To what extent it will save you money is not precisely known, but the fact that it will create a heating and cooling environment that runs at optimal efficiency is a provable fact.

Caring For HVAC Equipment

cleaning HVACWe specialize in St Louis HVAC and Restaurant Equipment service and sales near Kirkwood MO.  Today, we talk about proper maintenance of your equipment, whether it be stuff that functions in your commercial restaurant or other environment, all things need to be properly maintained and when ignored, like so many are inclined to do, they will only end up performing at sub-par levels and even have the potential for avoidable repairs.  “Perform thorough cleaning on a regular basis. – Either weekly, monthly or semi-annually, depending on the piece of equipment, there are deeper cleaning procedures that need to be followed. The purpose of more thorough cleaning is to get those places that are hard to reach or to just tackle the grime that accumulates over time.”

You will also want to make sure that others are all on board with your Commercial HVAC equipment in St Louis when it comes to the things you would like done to properly maintain the commercial equipment that you have in the building.

Part of the long term care of your HVAC in St Louis near Kirkwood, also involves regular check-ups if you will.  You ought to regularly inspect your restaurant equipment and HVAC system in St Louis MO.  In fact, there is a perfect time to do this, according to our favorite site for commercial HVAC information.  They say the following, “Any time you perform a thorough cleaning on your restaurant equipment, inspect any moving parts, utility connections and other components for wear, tear and leaks. Catching and correcting small maintenance issues early (like a water leak caused by a loose hose fitting) can save you from more expensive repairs in the future. You can even set up a service contract with a local manufacturer-authorized agent and have them inspect your equipment.”
