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.

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.

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.


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.

Routine Maintenance Effects in HVAC

routineWhen we gather our thoughts in an effort to bring you the most interesting and pertinent information in the HVAC field, we come away a little spun out at times, but not today.  The following several excerpts are covering St Louis HVAC sales near Florissant MO and the importance of efficiency in all systems alike.  Moreover, the point to drive home, is the fact that routine HVAC maintenance in St Louis is well worth the effort.

“Fewer than half of companies perform preventive or predictive maintenance on their building HVAC systems – even though studies show that good maintenance can cut HVAC energy costs while also extending equipment life, improving occupant comfort, and increasing uptime.”  Routine HVAC maintenance near Florissant MO can reduce HVAC energy costs by 5 to 40 percent depending on the system or equipment being maintained.  The heating and cooling industry has a name for the process of efficiency loss over time.  They call it energy performance degradation and routine maintenance is imperative in order to minimize this process in your St Louis HVAC system. “A variety of HVAC components need ongoing maintenance or energy performance degradation can occur.”

Regular scheduled maintenance of heating, ventilation and air conditioning (HVAC) systems can increase their efficiency, and a number of studies have quantified energy savings from maintenance, as well, so the only obvious answer, and the entire purpose of this particular post to explain, is to have your St Louis HVAC near Florissant MO routinely maintained by an expert as to minimize the energy performance degradation as much as possible.  You will see more in the way of specific suggestions in the maintenance if you read our next post on behalf of your HVAC maintenance company in St Louis MO.  Until then, understand that the facts are the facts in keeping your system working at its best.

Cooling Costs and Routine Maintenance Effects

hvac maintenanceIn sticking with our recent subject of HVAC upkeep as it relates to efficiency and overall heating and cooling system health, we are going to push forward, citing a handful of additional studies, and explaining in more detail all that it means to have a healthy HVAC system.  One particular study that we found on behalf of your St Louis Cooling Sales near Wentzville MO, had the following to offer, “The study included HVAC systems setpoints and schedules, economizer operation, ventilation controls and settings, and HVAC system efficiency and fan power (these last two variables were included as surrogates for adequate maintenance and balancing of the HVAC system).”

As a result of the above analysis, Portland Energy Conservation Inc. found that building operation and maintenance programs specifically designed to enhance the operating efficiency of HVAC and lighting systems decreased energy bills 5 to 20 percent in commercial buildings, without significant capital investment.  These findings are undeniable as energy efficiency and cost involved in heating and cooling are totally measurable, and therefore easy to study the effects had by maintenance on such results and numbers.

On behalf of your St Louis Cooling service near Wentzville MO, we bring you the conclusion that these results are real and the facts are of relative importance to anyone responsible for an HVAC system in St Louis or anywhere around the globe.  Another piece of supporting evidence is as follows:  The National Center for Energy Management and Building Technologies conducted 45 interviews with industry experts, and concluded that effective scheduled maintenance decreases energy bills 15 to 20 percent in commercial buildings.”  Found on behalf of your Heating and Cooling Maintenance near Wentzville, this tidbit reinforces that the facts are coming, not only from those in the energy realm, but also from the people in the trenches.  Take heart, if you want to fully optimize your savings and the effectiveness of your heating and cooling system in St Louis, call for routine maintenance and get on a regular schedule today.

Finding a Good Fit For Your HVAC Service

HVACYour HVAC service in St Louis near Chesterfield is looking at helping you find a good HVAC technician and offering up advice on the best way to get that handled.  We researched the subject recently on behalf of your St Louis HVAC sales and service near Chesterfield and managed to come up with five nuggets of advice on the subject.  These are things to look for when shopping for your next repair person in the HVAC industry.

Find someone with a decent amount of experience if you can.  While you don’t necessarily need to hire the most senior technician you can find, you do want one that has a fair amount of experience in the HVAC industry. “Most master technicians will gain experience in apprenticeships or similar programs that allow them to work alongside a seasoned technician. Make sure the crew you hire has technicians with several years of experience, and that those technicians will be assigned to your property.”

Besides experience, the presence of HVAC credentials is another biggie.  Many people proceed and glaze right over this one, assuming that to be in the St Louis HVAC service business must mean that they have the proper credentials.  That is simply not always true.  “If a license is required for HVAC repair in your city or state, make sure you check credentials before making a hiring decision. Licensure shows that the technician has been trained and tested in your state to properly install HVAC systems according to the state’s building codes. Insurance means that both you and the technician are protected in case there is an injury or damage to property. Look for technicians with both of these credentials in place.”  So, as you read, it is a liability point, not even so much capability.  The latter is determined more by their level of experience, hence, our first point.  Stay tuned to this St Louis HVAC installation site for more information and things to look for in a service tech.

The Energy Usage Cooling Dilemma

energy efficientWe recently stumbled upon the subject of heating and cooling your home or business in the most efficient ways possible and in doing so, we were introduced to a few experts on the subject, Nexia, a home automation system, offered by Ingersoll Rand, a top notch company in the world of technology.  From your Heating and Cooling Sales and Service in St Louis near Wentzville, we bring you a bit of information we gathered online and from the above sources on the subject to the most ecofriendly and cost effective ways to heat and cool your space.

First off, things surrounding the heating and cooling of your space in St Louis must be interactive and take full use of smart technology in order to be the most efficient that they can be.   Nexia, mentioned above, is one of the products Ingersoll Rand offers to help consumers understand how their homes use resources. “It works by connecting devices — from HVAC systems to appliances to lighting — to a central hub. The ‘Nexia Bridge’ then transmits information about the home’s performance to its owner’s chosen device, be it a tablet, mobile phone or computer.”

Interestingly enough, I think this is a way, according to our St Louis Heating and cooling research near Wentzville, of discussing optimization.  This can hopefully take place when all of the energy consuming systems are looked at together and this is what that product does.  “I think optimisation, whether we’re talking about a commercial building or a home, happens when we connect all of these various systems together and gain some insights,” says Tew. “I’m a huge believer in continuing to search for the data that gives you the right insight.”  Obviously, there is a broader point than simple energy understanding.  “Making homes more efficient doesn’t just result in savings for consumers — reducing energy use also benefits the environment.”



Heating Sales Brings You Air Handlers

air handlersWe are writing here to answer a question that many of us were unaware of the answer to regarding air handlers.  On behalf of your Heating Service Company in Earth City near Wentzville we are here to say that the air handler unit it unbeknownst to most and in researching we discovered that very few know what it was in the heating and cooling world.  “An air handler unit may resemble a furnace in appearance, but its purpose is very different. It conditions and circulates both cool and hot air, depending on what time of year it is. An air handler works in tandem with your air conditioner or heat pump to help get the most efficiency from your HVAC system.”

We can talk here about what, exactly, this air handler is on behalf of your Earth City Heating service near Wentzville MO.  “The air handler is the inside component of your HVAC system, working with your split-system air conditioner or heat pump. Air handlers connect to existing ductwork, distributing the conditioned air through your home and returning it to the air handler. The air handler blows the air (where the heat’s been removed by the evaporator coil) through the ducts in your home.”

Air handlers come in a variety of different sizes. The smaller ones are known for having only an air filter, blower, and coil. According to your Heating Install in St Louis, these are called terminal units, blower coils, or fan coil units.  When you look closely at the larger handler, known as a makeup air unit, you will see that it conditions 100 percent outside air; no recirculated air in this situation and the air handler that is only made for outside usage and will usually be found on the roof is called a rooftop unit.  These are almost always strictly for commercial use alone, according to your St Louis Heating and Cooling Repair near Wentzville.

HVAC Control and Automation

control hvacYour St Louis HVAC installation and sales near Hazelwood is talking today about control and automation systems for industrial air conditioning and commercial air conditioning.  It is apparent that such a thing is responsible for delivering intelligence to HVAC systems. This intelligence helps you better manage your resources, schedule HVAC contractors and AC maintenance, and prolong overall product lifecycle—in addition to a number of other benefits according to many experts in the world of HVAC sales and service.

According to our research on behalf of your St Louis HVAC Service and Sales near Hazelwood, the benefits of utilizing control and automation systems for your industrial air conditioning and commercial air conditioning HVAC systems include: Consistency and comfort, lowering of utility bills, increase in property values, and less time spend on consumer complaints.

They overlap a bit, according to your St Louis HVAC sales near Hazelwood, with comfort and consistency also having to do with lower costs to operate.  “The computerized controls offered by automation systems can help maintain a more even temperature. This leads to lowered overall costs, without any ‘hot spots’ or cool chills.”  Costs being lesser also becomes apparent in the installation realm.  “On average, installing an automation system can decrease your utility bills by 15%. This 15% puts the savings around $.20 to $.40 per square foot. This significant savings can be used to offset the original purchase and setup costs—and then once the system is paid can be used for other HVAC-related costs like AC maintenance or repairs. The savings can also be put into a fund for future repair or replacement costs for your industrial air conditioning system. In some cases, the contractor may allow the payment of the control and automation system over time, allowing the savings to help pay for the control retrofit.”  Call your local HVAC installation and find out more.
