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.

Cooling Without Central Air Conditioning

attic fanWhen it comes to cooling your home or office in the summer heat or other times of year, depending upon how close you live to the equator, many would insist on the presence of a central HVAC system in order to get the job done.  However, we are here to tell you that you really don’t need that at all.  Is it nice and chill?  Yes.  Is it a requirement to beat the heat?  No.  On behalf of your Cooling Sales and Service in St Louis near Overland MO, we did some hunting and pecking online to decide some of the best, most effective ways to cool your space without central air conditioning.

Fans may be one of the keys.  “Whole-house fans may seem old fashioned, but they’re enjoying renewed popularity. The idea behind them is simple: A powerful fan draws cooler early morning and evening air through open doors and windows and forces it up through the attic and out the roof vents. This sends hot air up and out, cooling your house and your attic.”  Typically these attic fans (as they have been called in the past) are mounted in an upstairs stairwell or hallway ceiling where there’s at least 3 ft. of clearance above the fan itself, according to your St Louis Cooling maintenance near Overland.

What are the advantages to a fan that works to cool your entire house in St Louis?  Well, for starters, you will save a lot of money in energy savings.  You will use approximately 90 percent less energy with a fan than you will with an air conditioner.  When you live in a dryer climate, it is not uncommon for an attic, or whole-house fan to replace an air conditioner entirely, according to the information we gathered in our research on behalf of your Cooling Sales and Service in St Louis near Overland.  We have other cooling ideas to share and plan to do so in the next two posts that follow.

HVAC Take One

take oneWe like to bring you all the latest news in the world of HVAC on behalf of your St Louis HVAC sales and service near O’Fallon MO, but sometimes it is important to reevaluate the information you share and attempt to cover more of the basics for those in your audience who may be unaware.  So, today, we will look at the basics of St Louis MO HVAC and hopefully help our readers get on the same page before we start covering more advanced details in our future posts.

Most homes are heated and cooled through a central, whole-home, Heating, Ventilating, and Air-Conditioning system (HVAC). The HVAC may well be one of the most expensive and energy hungry systems in the home, so the more you know about your HVAC, the better off you will be, especially if you act on what you know. A well-informed homeowner will save money and have a healthier, more comfortable home indeed.

When you hear people refer to St Louis HVAC near O’Fallon as split, this is a real thing and is due to the following, “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.”  Furthermore, the AC (or heat pump)has a condenser/compressor involved in its functioning, according to your HVAC sales and service in St Louis and it is typically installed outside the home, while the furnace, the evaporator and the blower are installed inside the home’s St Louis HVAC near O’Fallon MO.

 

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.

 

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.
