In the world of HVAC, there are many things that you may run across that require the consultation and even employment of a professional, like those available at your St Louis HVAC installation near St Peters MO. However, sometimes, the repair may be manageable by you. When it comes to replacing a thermostat, you may be surprised how simple this is.
We will only look at installing digital units here because there is really no benefit to installing a mechanical unit and we want to emphasize that only you can decide if this sort of maintenance is something that you can handle. Don’t feel badly about the use of a professional when needed. If you are having problems with your furnace or air conditioner, you can and should begin by checking the thermostat for proper operation. Make sure you begin by shutting the power off to the furnace and/or ac unit and switch the fan from auto to on mode, according to your St Louis HVAC repair near St Peters. At this point, if you are having furnace problems, you can disconnect the r and w terminals at the thermostat. Twist the two wires together and then turn the power back on. If the furnace comes on, the thermostat is bad and you should continue with thermostat replacement. If the furnace does not come on, the problem is not the thermostat and you would be wise to seek a professional HVAC repair company for further assistance.
If you are having ac problems, disconnect the wires from the r and y terminals and twist them together. Turn the power back on to the furnace and/or ac unit. If the system runs the thermostat is bad and should be replaced. If the ac still does not run, the problem is not the thermostat. If you stay tuned to this blog, we will cover next, some of the questions surrounding the type of thermostat you may need when your HVAC system goes out.
Looking further into the effects of natural disasters on HVAC systems on behalf of your St Louis Heating and Cooling Repair near Clayton MO, we found some interesting information regarding the Great East Japan Earthquake and the tsunami that resulted in March of 2011. “The aftermath of the Great East Japan Earthquake and resulting tsunami of 11 March 2011 provided researchers an unexpected opportunity to explore the relationship between air conditioning and risk of heat-related death.” According to our research on behalf of St Louis Heating Sales near Clayton, there have been many prior studies that reported associations between access to and/or use of air conditioning and lower mortality risk. However, the new results, published in Environmental Health Perspectives online, suggest that reducing the use of AC during summer heat may not necessarily have adverse consequences for human health, depending on the age and existing health of the people being considered.
The following was reported, “The 2011 earthquake and tsunami severely damaged the Fukushima Daiichi Nuclear Power Plant and caused severe electrical shortages in the Tokyo metropolitan area. To conserve energy, the government strongly encouraged residents served by Tokyo Electric Power Company and Tohoku Electric Power Company to reduce electricity consumption by 15% from July to September of 2011.”
The urgency was heightened to reduce energy consumptions although campaigns promoting energy conservation have long been a summertime fixture in Japan. Many residents of Japan working to reduce cooling bills and energy consumption swapped AC for fans. The end results were not troubling to their health. Interestingly enough, heat related deaths actually decreased during this time.
Looking even closer and into more detail at what happens when natural disaster strikes and your HVAC is involved, we come across information from our most recent research on behalf of your St Louis Heating Installation near Wentzville MO that we wish to share. “When a tornado strikes, it comes with high winds, but also lightening. Hail, on the other hand, could follow a tornado or severe storm. It comes with heavy pelts that could subsequently damage your HVAC system.” It is recommended in order to protect the fragile parts of the condenser coil, that one installs a hail cover over the air conditioning unit. Although it may not deflect everything since small debris can go through the guard, lodging in the equipment, it is better than nothing in terms of level of protection. If something does lodge in the equipment, however, we found through our recent research, that you ought not attempt to use your AC until you have consulted an expert.
Water damage is another big deal when it comes to the aftermath of natural disaster. In our recent studies on the subject on behalf of your St Louis Heating service near Wentzville, we also found that many people are affected by this as well. “A storm or hurricane comes with lightening and heavy rains, causing water damage. In fact, when the storm hits an area, its slow movement could cause a significant amount of water to accumulate in your yard and around your HVAC system. Debris and grass could wash into the HVAC unit as water rises.”
In light of all possible disaster damage, it is recommended that before you experience severe weather, it would be an excellent idea to contact an HVAC contractor to inspect your outside HVAC unit. The HVAC professional would make sure that the unit is elevated to a height to keep out as much standing water as possible.

We 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.
When 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.
“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.
Headed 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.
Besides 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.
When 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.
In 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.
