HVAC Noises

HVAC Noises

noisesNoises can be defined in a multitude of different ways despite the source of the noise.  In general, we can categorize any noise as expected or unexpected.  In the HVAC world, according to your St Louis MO HVAC install and repair, we can break these noises down into a lot of different areas and not all of it is unusual or of concern.  “No matter the age or price of your HVAC unit, it’s going to make noise.” That’s right, you may have become immune to the low hum that your HVAC unit emits, but it is important to note anytime there are new, unsettling noises and sounds happening.

Of course, not all noises suggest that you’re staring down an impending road of disaster, however most St Louis HVAC systems near O’Fallon MO, make noises that signal it’s time for maintenance or repair. Below are some examples of those sounds and potential causes, as well as a few tips for eliminating said noises, according to your St Louis HVAC sales near O’Fallon.

Thumping, clanking or banging:  “Other than the cheerful, big-eyed rabbit in Bambi, thumping is usually an unpleasant and ominous sound. So, if you’re hearing banging, clanking or thumping, that may be a sign of trouble brewing.  If any of these bothersome sounds are coming directly from your HVAC system, this could mean there’s an issue with your HVAC’s blower assembly. We suggest turning off your HVAC system before the issue worsens, and then calling a technician to inspect the problem.”  Popping:  Popping sounds when you turn your system on and off you can breathe a sigh of relief. The popping sound is due to your metal ductwork expanding and isn’t a problem whatsoever, according to your St Louis HVAC repair near O’Fallon MO., For elimination of the sound, insulation such as foam or rubber can help limit the noise. Other sounds will be covered in posts to follow on behalf of your St Louis HVAC installation and repair.

We suggest turning off your HVAC system before the issue worsens, and then calling a technician to inspect the problem.”

HVAC Certification in Today’s World

HVAC Certification in Today’s World

certifiedLooking to become certified in a growing field of high demand?  Have you ever stopped to think about pursuing a career in HVAC service near University City MO?  The schooling can be overwhelming these days given everyone’s busy life and schedule.  Some of the old methods of attending night classes or going back to school to receive an HVAC certificate might have seemed out of the question in the past and especially in today’s busy world. When researching the subject on behalf of your St Louis HVAC installation and sales, we recognized that the good news is: now you can study online to get certified. In some cases, it’s true that you can even take your exams online. We will discuss the ins and outs of getting certified in HVAC from the comfort of your own home, but for starters, it’s pretty amazing to know that you can.

“It is usually not required that technicians attend a trade school to receive a diploma in HVAC.”  Although often times a strong option for getting your HVAC education, there are also online options in today’s industry that will allow you to accomplish the same thing.  One reputable source online confirms, “While a local trade school is a strong option for getting your HVAC education there are also online classes and state HVAC certifications you can earn through a combination of hands-on experience and an examination process. At the end of these, you may receive a certificate or a diploma.”

The term “certification” can be confusing and mean different things, according to your HVAC installation in St Louis MO near University City.  It is sometimes used in regard to state requirements, depending upon where you live. When getting certified through your state you are getting a license to work and perform HVAC installations, maintenance, and repairs in the field, according to all we read on behalf of your St Louis HVAC sales and service.  Read our next post here for more details on how to proceed online.

Thermostat Determination With HVAC

Thermostat Determination With HVAC

thermostatHere, on behalf of your St Louis HVAC sales and service near Ballwin MO, we discussed the possibility of handling your own thermostat installation, assuming you may need one.  You’re your HVAC causes issues, it is important to be able to diagnose the problem to the best of your ability, then seek professional help when you come to the end of your rope.  Say you determine that it is indeed a thermostat you need for your St Louis HVAC system near St Peters.  What type of thermostat do I need?  This is a question best answered by researching.  In doing so, on behalf of your HVAC sales in St Louis MO, we found that the first step is to survey your heating and cooling systems to see what type you have (heat pump, boiler, furnace, electric baseboard).  “If you have a boiler you need to count the number of wires in the old thermostat. If you have three wires it requires a special unit.”

According to the expert articles we read from online on behalf of your St Louis HVAC sales near Ballwin MO, we know that another thing is to check the number of stages you have of heating and cooling. “This can best be done by looking inside the old thermostat. If you have more than one stage of cooling there will be y1 and y2 terminals with wires on them. If you have a two stage furnace, there will be w1 and w2 terminals with wires on them.”

You must also find out what the source of power is that is available to the unit. This can be accomplished by looking at the existing control and looking for the following, according to our research on behalf of your HVAC sales near Ballwin. “If you are replacing a digital unit, look for a C terminal. If there is not a C terminal or there is no wire attached to it, you will need a battery operated replacement unit. If there is a C terminal with a wire attached to it, You can use a system or battery powered unit. If you are replacing a mechanical thermostat, it is best to get a battery powered replacement.”

HVAC Thermostat Diagnosis

HVAC Thermostat Diagnosis

thermostatIn 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.

Bottoming Cycles and Recycling in HVAC

Bottoming Cycles and Recycling in HVAC

HVACAs a follow-up to our previous posts regarding St Louis HVAC service near Overland and some of the heat recycling methods out there, we are going into more detail about bottoming cycles.  “Bottoming cycles are mostly used in industrial facilities in the chemical, paper, and primary metals sectors, as these industries often have high-temperature waste streams that are favorable for waste heat recovery. As much as 20-50 percent of the energy consumed in some industrial processes is ultimately lost through waste heat contained in streams of hot exhaust gas and liquids and through heat conduction, convection, and radiation from hot equipment surfaces and heated product streams.”

The goal, so to speak, is a simple one that applies to only some processes as others may not be safe enough when it comes to the waste they produce.   The overall energy efficiency of some industrial processes can be improved by capturing and reusing the waste heat, however, in situations where it makes sense from a safety and function point of view.  In our recent research on behalf of your St Louis HVAC installation near Overland MO, we discovered many facts surrounding the process to share here and in posts to follow.

“In some cases, such as industrial furnaces, efficiency improvements resulting from waste heat recovery can improve energy efficiency 10-50 percent. A study by the U.S. Department of Energy’s (DOE) Energy Efficiency and Renewable Energy office (EERE) identified research, development, and demonstration efforts to expand waste heat recovery practices in the U.S. industrial sector.”  In the aforementioned study, the waste streams analyzed showed that roughly 60 percent of unrecovered waste heat is low quality (i.e., temperatures below 450°F).  We will explore more regarding what this means as we further our research into heat recycling and HVAC in St Louis.

Bottoming Cycles in HVAC

Bottoming Cycles in HVAC

recycled HVACWe are moving along the HVAC train and looking for new and exciting information to share with you from your HVAC installation and service in St Louis near Chesterfield MO.  We found some interesting info on CHP or Combined heat and power systems and thought we ought to pass it alone.

“Combined heat and power (CHP) systems are being used by a wide range of applications to reduce the overall energy intensity of industrial systems. There are two types of CHP, depending on whether the system produces power first, then heat, or heat first, then power.”  According to your HVAC sales in St Louis, the topping cycles involve hot exhaust of an electricity generator.  Something like a natural gas turbine or reciprocating engine, is used to provide process heat, hot water, or space heating for the site. “According to preliminary 2015 data, topping cycles are used by 89 percent of total CHP capacity.” In bottoming cycles, also referred to as waste heat to power, wasted heat from a furnace or other high-temperature industrial processes is recovered and used for power production, which is also found to be noteworthy in our recent research as this is a form of energy recycling.

According to our HVAC sales St Louis near Chesterfield and the research recently done online, the bottoming cycles typically use waste heat boilers or steam turbine systems. “Ongoing research, development, and deployment efforts are focused on these systems as a way to reduce wasted heat and increase industrial energy efficiency.”  From an HVAC perspective, bottoming cycles are most times being applied in industrial facilities in chemical, paper, and primary metals sectors since these particular places often have high temp waste streams that are best dealt with using waste heat recovery.  All of this and more can be discussed as it applies to St Louis HVAC near Chesterfield and we will attempt to elaborate in future posts on this very subject.

On-Command Hot Water Recirculator

On-Command Hot Water Recirculator

water recirculatorThe world has been leaning green for the past several years now and HVAC is no exception.  “As recently as December 2013, President Obama said that the U.S. federal government must double its reliance on renewable energy by 2020, meaning that 20 percent of its energy supplies will need to come from renewable sources. The reliance on green energy has several benefits, including the ability to decrease the ‘environmental footprint’ on the plant, according to the U.S. EPA as well as to alleviate energy security issues while spurring economic growth within the U.S.”

We set out, on behalf of your St Louis HVAC sales and installation near Kirkwood, to deliver more info on just what that means from an HVAC perspective.  We know that the green trend means plenty of changes to the HVAC industry, but just exactly what, we were not sure. “Companies in the U.S. and worldwide are involved in research to create more energy-efficient traditional systems as well as new types of systems that run off alternative energies, such as geothermal or solar.”  We found a lot of information when researching for your St Louis HVAC sales near Kirkwood, but also realized that even more improved technologies can be expected in the future as companies work toward changing this country’s reliance on fossil fuels, which in the U.S. stands at 82 percent. “Only about 9 percent of the country’s energy supplies currently make use of renewable sources, which leaves plenty of room for change in HVAC systems.”

The on-command hot water recirculator is the one product we will describe today, in the HVAC green movement.  “This product, produced by Taco, Inc., out of Cranston, Rhode Island, saves money, energy and water while delivering hot water in a timely manner.” It involves installation of the “On Command” pump that attaches to the hot and cold water lines under a kitchen or bath fixture in a home, according to our HVAC research. “When activated, it allows the cool water being drained to circulate back to the water heater through the cold water line, allowing hot water to be delivered at any time 24 hours a day.”  The energy conservation is obvious here and kicks off our series in the St Louis HVAC installation near Kirkwood on HVAC renewable energy and green movements.

HVAC Trends

HVAC Trends

trendsHeating, ventilation, and air conditioning is what makes up the HVAC industry and is a subject on which we find ourselves focused often in order to bring you the latest information.  “It’s something that you’ll find in buildings, homes, and even vehicles. We often take these needs for granted, wanting to turn on the heat when we’re cold or the A/C when we’re warm.”  There are trends within the industry that relate to St Louis HVAC near Clayton and these things must be followed in order to help keep a building altogether healthy from a heating and cooling perspective.

When it comes to trends, regulations cover a wide area of ever-changing guidelines.  “Regulations drive HVAC industry trends. In the northern US, furnaces must have a 90% efficiency rating, but in southern states, only an 80% efficiency rating is required.”  Your St Louis HVAC installation near Clayton knows that they must stay on top of regulation requirements.

“This means HVAC industry trends tend to be fueled by local and regional data instead of an overall set of trends. To discover what is in store for this industry, we must look at emerging technologies, integration, and how local regulations are evolving to get a picture of what to expect in the days and years to come.”  There is a smarter industry on the horizon when it comes to HVAC sales and repair in St Louis.  “Many within the HVAC industry are beginning to automate their sales and service processes, allowing them to cut their customer acquisition costs to keep pricing competitive.”  Using technology to their advantage is another way that HVAC in St Louis is trending in a way to keep up with other competitors and to maximize ability with less effort and cost.

HVAC Take Two

HVAC Take Two

take twoIs your HVAC system a heat pump?  If so, we have information to share with you, on behalf of your St Louis HVAC Sales and Repair near Fenton MO.  The deal is that if your HVAC system is a heat pump, it won’t have a separate furnace. Dave Moody, an HVAC industry pro with Service Experts, explains, “A heat pump works like a regular air-conditioner in the summer, then essentially works in reverse in the winter, serving both cooling and heating purposes.” A heat-pump system will still have indoor and outdoor components.  You may wonder what they are, so read what we found out below in our St Louis HVAC sales research.

Outside the house you’ll find the compressor and condenser components of the central air-conditioner (or heat pump), which are mounted in a metal cabinet with a large fan, that is the typical set up for anyone with a St Louis HVAC near Fenton who possesses a heat pump in their home.  Also, there is a possibility for a slight variation of the above description. “One alternative to a split-system is called a ‘packaged’ system, in which all components are installed in a single unit outside the home, with ducts entering through the wall of the home. These units may be preferable for a homeowner who doesn’t want to waste space on the interior of their home with heating and cooling equipment.”

Many people learning, along with those of us researching to teach more, tend to overlook the V portion of HVAC installation in St Louis near Fenton MO.  Here is what one online expert says about it, “Not often addressed in most HVAC installations is the ‘V’ – ventilation. Most homes rely on infiltration, or air that seeps in through gaps and cracks in the home’s shell, for limited fresh air. Service Experts’ Moody says, ‘As indoor air quality (IAQ) is increasingly implicated as a big factor in human health problems, mechanical ventilation systems are becoming more commonplace.’  We plan to elaborate more on the ventilation portion of our HVAC itinerary in the near future here on behalf of your HVAC installation in St Louis MO near Fenton.
