Brief History of HVAC

Brief History of HVAC

HVAC commercial installation in MOFor those who don’t know, HVAC is heating, ventilating and air conditioning. Many are familiar with the various applications of HVAC in today’s world, but what were there usages of HVAC in our history? It is surprising how far back in time you have to look to get to the origins of what, at first glance, seems to be modern day technological innovations. While there may not be glaring similarities with the technology we use today, even people in ancient times attempted to moderate the comfort and with various forms of climate control and ventilation.

From the 1000s to the 1400s it was the time of the Greeks, Romans, Egyptians, Chinese and the Native Americans. In this time period the Egyptian’s used human powered fans, while Native Americans were known for using rope fans to cool themselves. Roman’s were quite possibly the most advanced civilization in this timer period. They used technology known as hypocaust, which was a central heating system with a furnace in the basement and flues flowing throughout the structure to distribute heat. It h even provided steam for the baths to certain wealthy and privileged Romans. Chimneys were used extensively towards the latter part of this timeframe and the infamous Leonardo Da Vince was known to have built a water powered fan to ventilate for cooling and ventilation purposes.

The 1500s and the 1600s brought forth a fair amount of advancements is HVAC also. In Europe ventilating equipment was integrated into the mining industry when fans were used to force fresh air into the shaft that was being excavated. The notion of chimneys for buildings and homes was imported to America from Europe, so large quantities of wood and coal were being used during this era for internal warming purposes. Invention of thermometer by Galileo forever altered the way temperature was measured and allowed humans to track and accurately regulate inside temperatures.

Maintaining Commercial Beverage Systems

Maintaining Commercial Beverage Systems

beverage system restaurant equipment in moAmerican Services offers a wide range of restaurant equipment repair and maintenance near University City.  We knows that when it comes time to offer your customers refreshments, you want to make sure that you are offering them the best testing product that you can.  In order to make sure that is happening,  your beverage dispenser needs to have a clean and fresh water supply.  This can truly make the difference between a refreshing beverage and a drink that will make customers cringe.

Depending on where your restaurant is located will often determine the quality of water that you receive.  One of the main things to consider is where your water is sourced from.  Cities will differ from rural areas and different states and municipalities will have a wide range of water quality standards.  Some water is sourced from aquifers, lakes, rivers, or even reservoirs for places that don’t have a high water table.  In addition, depending on geography the water might be subject to runoff contamination, chemical contamination and even different types of soils and rocks in the soil that can induce issues.  With all of that in mind, it’s important that your beverage systems have a good filtering system to insure that whatever the state of your water might be in, it is filtered and cleaned prior to your customers even touching it. 

In order to get the best quality of water you will need to have it professionally tested.  That way you can determine what kind of water you have and what the best course of action might be.  If you’re dealing with hard water, you might need softening treatments because hard water can lead to buildup which in turn can cause a variety of issues.  Sediments in your water will require a filter with micro fibers to sort out all of the various contaminants. Strange taste or chemical issues can often be handled by a high quality charcoal filter.  The condition of your water will dictate the course of action you take.  It is important to get your water tested prior to your beverage dispenser installation and afterward to make sure all your efforts paid off.  Because in the end, you want to offer your customers the best taste experience they can have and that will keep them coming back again and again.


Restaurant Refrigeration Equipment Efficiency

Restaurant Refrigeration Equipment Efficiency

restaurant refrigeration in MOAmerican Services refrigeration repair service near Fairview Heights knows that restaurants often use about 5 to 7 times more energy per square foot than other commercial buildings, such as office buildings and retail stores. High-volume fast-food restaurants may use up to 10 times more energy per square foot. Most commercial kitchen appliances are designed to be energy intensive. For instance, a typical electric deep fat fryer uses more than 18,000 kilowatt-hours of energy per year. This translates to an excess of $1,700 in electricity annually, for just one piece of equipment. 

As energy costs increase, investing in energy efficiency is the best way to protect your business against these rising prices. You can reduce your restaurant’s energy consumption by following certain cost saving tips. Select Energy Star qualified appliances when you’re in the market for new equipment. Energy Star qualified commercial refrigerators and freezers can lead to an average energy savings of 30 percent.

Shrewd business people think in terms of life-cycle costs, which include purchase price, annual energy costs, and other long-term costs associated with the equipment. Higher efficiency appliances typically cost more up front, but significantly lower utility bills can make up for the price difference.

Refrigeration is often one of the most expensive tasks that certain businesses must account for. Having equipment that is running properly is very important. If you leave your equipment ON when it is not performing useful work, it costs you money. Properly maintaining and performing timely repairs is vital. Leaky walk-in refrigerator gaskets, freezer doors that do not shut, all add up to money wasted money. Don’t let everyday wear and tear drive up your energy bills.

The performance of your kitchen equipment changes over time. Thermostats and control systems can fail, or fall out of calibration and need to be readjusted. Take the time to do a regular thermostat check on your refrigeration equipment and reset them to the correct operating temperature. Features that could potentially save energy include improved insulation and components such as high-efficiency compressors and motors.

Choose Energy Star Ice Machines for Restaurant Equipment

Choose Energy Star Ice Machines for Restaurant Equipment

restaurant equipment ice machine in MOAmerican Services Restaurant Equipment installation service in Ladue knows that automatic commercial ice makers are widely used by food, hotel and patient care providers. The equipment is manufactured selected based on a combination of features that best fit the application that the machines are intended for. Common attributes include ice type, production capacity, ice hardness and clarity, as well as ice form and size. Commercial ice makers can be classified into either of two general equipment types, batch-type and continuous-type. Batch-type ice makers harvest ice with alternating freezing and harvesting periods. Continuous-type ice makers produce ice through a continuous freeze and harvest process and include flake and nugget ice makers.

No matter what type of ice machine is in order, selecting an Energy Star product is a good idea. Air-cooled, batch-type and continuous-type commercial ice makers are all eligible for Energy Star certification. Also eligible are remote condensing units designed for connection to a remote condenser rack. Qualifying models must meet maximum potable water and energy consumption limits to earn the Energy Star. 

Energy Star commercial ice makers can save businesses money on their utility bills. Energy Star certified systems save around 1,200 kWh annually. This translates to $130 per year in electricity bill costs. ENERGY STAR batch-type ice makers are on average 15 percent more energy efficient and 23 percent more water-efficient than other models. For continuous-type ice makers, ENERGY STAR certified machines save around 1,500 kWh annually, or $160 per year of utility charges. 

Energy Star designated commercial ice machines cut down on your daytime electricity demand even further if they are outfitted with a timer. A savvy business-person can then shift ice production to nighttime off-peak hours. Interestingly, bigger ice machines are often more efficient than smaller ones, yet the price difference is usually not very large. Careful selection could yield twice the ice capacity at half the energy cost. For ice machines in Missouri, contact American Services.

Commercial Heating Options

Commercial Heating Options

industrial boiler repair in MOInstalling industrial heating systems near Clayton MO with sustainable resources is an attractive option offered by American Services.  We utilize energy sources such as solar and geothermal power. Heating options like these systems are good for the environment and are potentially more cost efficient than other options such as oil and gas. Since they often come with high startup costs, this type of commercial heating system is often passed over by smaller businesses with less available capitol.

Selecting an oil or gas steam commercial HVAC system may not be the most efficient choice, but it is one of the oldest and most widespread methods of heating commercial properties. The oil or gas is used to boil, condense and steam flows through the pipes. Besides being relatively inefficient, steam heating also requires additional time to circulate the heat. Once the boiler is started it must run for a while before the heating process begins.

Heating by using a water-based HVAC system is another available option. Much like steam heating, the water heating method requires a boiler to operate. The water flows through the system to radiators positioned throughout the building or property. Water-based heating systems come with their own efficiency issues. First of all, it is necessary to clear the air in the system every time the heating is started which slows down the warming process.

Industrial Boilers 

American Services can maintain and service your industrial water and low pressure steam boilers with no problem. You can count on us to keep your building inhabitable and do it at a reasonable cost.

Installing a heat pump is, on the other hand, a more efficient means of heating a building.  Interestingly, this process is heats by using a refrigerant. Then the process continues by pumping the heat generated throughout the commercial property. One of the best things about this method is that it does not require a fuel source to work. The heat pump method is a very efficient system that many folks use for commercial heating in Illinois.



Supplemental Cooling for Commercial Spaces

Supplemental Cooling for Commercial Spaces

portable cooling in MOCompact and portable computer cooling units conveniently fit into small spaces, providing you a fast on- the-spot cooling solution. It is unnecessary to over-spend when all you need is more moderate supplemental cooling. Computer controlled room air conditioner help create a safe environment to protect your equipment or valuable data. Using portable programmable air conditioner allows for cooling after-hours or during weekends and on holidays.

Portable air conditioners provide supplemental or instant emergency back-up cooling that can be used when the primary cooling system isn’t functioning properly or fails altogether. With a trend towards smaller, hotter servers, equipment shutdowns may be more likely to occur when or if the existing air conditioning system falters. Although small and easy to store, a compact unit producing 8,000 BTU can quickly provide cool and fresh air for up to 250 square feet. Furthermore, this option is available at a cost of around just $1 per day. Better yet the money up front needed to purchase a quality unit can be as little as about $300.

Dehumidifying modes is an option to take under consideration. Humidity can be just as much of a problem as heat when it comes to cooling commercial spaces.   Even a smaller, less costly A/C unit with a dehumidifying function can extract up to 50 pints of water per day. Another useful feature is a self-evaporative system. If equipped, an auto-drain system that eliminates the need to manually drain water from the unit. Multiple fan speeds let you customize the setting s and to control noise and air output.

Energy Saving Programmable Features: Cut costs by setting the unit to run only when you need it, and have it efficiently cool your space before you even get there using the 24 hour programmable timer– The timer allows you to set the unit to cycle on automatically, or once it is on, you can set it to automatically turn off.

Cooling Efficiency

Cooling Efficiency

cooling efficiency in MOThe average household spends more than $2,200 a year on energy bills and a good portion of this of this amount is for cooling costs. One function of the Environmental Protection Agency is to help Americans make good decisions, including those regarding your home’s air conditioning system. The end result of this assistance can mean lower energy costs, improved comfort at home and better environmental outcomes in the future. 

In fact, the energy used in the average house is responsible for twice as many greenhouse gas emissions as the average automobile. Power plants burn fossil fuels to produce electricity. Even though it is a more implicit form of pollution, it occurs nonetheless. By using less energy at home, you help reduce the emissions that contribute to the unnatural heating of the planet. ENERGY STAR is the government-backed program that helps us all save money and protect our environment with energy-efficient products and usage. For those in search of recommendations and information about energy-efficient equipment, the EPA’s ENERGY STAR program can help. 

For many the summer means running the air conditioner constantly, when the temperatures heat up, the efficiency of our air conditioners drop dramatically. In these months, the air conditioner’s thermostat should not be set any below 78 degrees. At the same time, the settings should not be any higher than 68 degrees in the winter time. Keeping to these guidelines will help maximize energy savings.

There is little need to make drastic lifestyle alterations. Rather, gradually adjust the temperature on the thermostat to help ensure everyone in the family is as comfortable as possible and more receptive to change. Reduce, or raise the temperature just one degree at a time and try it for a week. Over time, you might be able to adjust three or even four degrees comfortably and save a chunk of money.

HVAC History

HVAC History

antique stove for HVAC in MOAmerican Services HVAC repair and installation in St. Louis knows that in the 1700s and 1800s heating stoves made of brick were most commonly used. Additionally, the first mercury thermometer was invented, making temperature reading easy and accurate.  Benjamin Franklin invented the very first stove known as the first steam heating system during this time period. In England, direct fired heat exchange technology, using a stove with a furnace, was being used to warm up large factories.

In this 200 year span, Joseph black forged ahead with relevant discoveries on the topic of latent heat and James Watt was to forever be included in the history books by inventing the steam engine. Carnot initiated thermodynamics and the first and second laws of thermodynamics were made. James Joule discovered and published that work produces heat. For the first time heat was treated as a form of energy. Also, the first warm furnace was developed and boilers with higher capacity were used. Laws of gases were discovered and widely put to use.

The 20th century was a bustling time period for the advancement of HVAC technology. This era saw numerous inventions and rapid evolution of the HVAC systems. Furnace system with centrifugal fans, high pressure steam heating systems, massive fan systems and high speed centrifugal fans and axial flow fans with small electric motors were in extremely high usage.  Industrial air conditioning systems were devised by Sturtevant and Buffalo Forge designed a system to remove dust particles from air streams.

A cooling system was devised that could lower temperature to 10 degree Fahrenheit and a forced air system using a fan was made. The first centrifugal refrigeration machine was made for air conditioning large spaces, while hydronic circulatory pumps and radiators started to be used in the air conditioning systems for circulating water in the system. Furthermore, the first refrigeration with a compressor was made. In the 1900s the first residential air conditioning was made, panels for heating floors and ceilings were manufactured and the use of solar power as a power source was made.

HVAC Service for Hospitals

HVAC Service for Hospitals

hospital HVAC in MOAmerican Services commercial HVAC service in Missouri knows that during an emergency situation the last thing you want on your mind is the quality of air that you are breathing.  But if the wrong HVAC system was installed in your hospital or it has not been maintained regularly, then what you are breathing could become the next critical problem you have to deal with.

When dealing with the heating and cooling of a hospital there are multiple aspects to consider.  Since there are so many areas of a hospital, HVAC systems have to be specialized to filter areas properly.  For instance the waiting room doesn’t need the same level of filtration as the operating room.  Indoor air quality becomes extremely important depending on where you are in the hospital and each of those areas must be handled separately.  In addition, HVAC systems in hospitals also push a lot more air through the system than standard systems, up to 30 cubic feet per minute on the high side compared to 15 cubic feet per minute on the high side in standard commercial applications.

With that in mind it is imperative that these HVAC systems are properly maintained and regularly scheduled checkups and filter changes are conducted.  Depending on the application, filters should be changed quarterly or yearly depending on the filter type and what its used for.  Nevertheless at a minimum the HVAC system should be checked every quarter and any issues in the meantime should be reported immediately.  This is important because patients with compromised immune systems are especially susceptible to airborne pathogens.  

Maintaining an HVAC system in a hospital environment can be expensive and time consuming, but keeping the system in good shape and properly maintained can save thousands of dollars in repair costs in the future.  In addition, keeping patients and workers safe and infection free is the goal, so expense is relative.  Proper maintenance of any HVAC system is important, but when it comes to hospital HVAC and saving lives, nothing could be more important.
