Geothermal heating and cooling systems use the heat that is naturally created by the Earth to stabilize temperature. These systems are highly efficient, have very little cost associated with daily use, and are a green form of energy. Today, the team at American Services wants to give you a quick review of how these systems work. Let’s get started!
Under ground, the temperature of water holds at a steady, more comfortable temperature that averages between 42 and 80 degrees Fahrenheit depending on what part of the country you are in. This temperature holds unchanged all year long despite the season or air temperature above ground. Geothermal systems tap into that constant temperature via either a closed or open loop system and heat pumps. With a close loop system, a set of underground pipes are laid and filled with refrigerant. The refrigerant then runs through the pipes (thanks to the use of a heat pump) and absorbs heat from the water underground. In the winter, the system absorbs heat that is used to warm the air and in the summer the system absorbs the cold that is used to cool the air. With an open loop system, the same process happens but instead of refrigerant pond or well water is used to transfer the hot or cold.
Geothermal systems are friendly to the environment because they use a naturally occurring source to regulate temperature. These systems are more costly to install, yet the monthly energy use is much lower and results in more affordable energy bills.

Cooling load is a term you may have heard used, but aren’t sure what it means and how it affects the temperature of your building. Today, let’s answer some questions on that term!
When your HVAC technician says “cooling load”, what is he or she referring to? When an HVAC professional speaks of a heating or cooling load they are referring to the amount of heat that needs to be continually removed or added to your structure to maintain the desired indoor air temperature.
What causes a cooling load? A cooling load is what happens in the summer when a building gains heat from the sun through the exterior of the building. People, lights, equipment, and appliances also add to this cooling load.
What does it mean to reduce your cooling load? When you reduce your cooling load, you are essentially reducing the amount of heat your building is gaining from the factors we mentioned above.
Why would should I work toward reducing my cooling load? Reducing your cooling load will help to keep your building from using extra energy for cooling. This will reduce your costs and keep your building at a more desirable temperature.
How can I reduce my cooling load? Reducing your cooling load can be done by:
- Adding insulation
- Installing energy-efficient windows
- Upgrading your lighting systems
- Reducing solar gain
- Using efficient equipment (electronics, etc.)
- Controlling ventilation

In the HVAC business, the characteristics that describe a comfortable home are defined together as your indoor air quality. To achieve a maximum comfort level, there are three factors that must be accounted for. These factors are temperature, humidity level, and cleanliness of the air. In this two-part series, we will discuss the areas of humidity and indoor pollutants. Giving details on what each are and how they work to create your most comfortable indoor air quality.
When measuring the amount of water vapor in the air, you will be given a percentage that is called your humidity level. The percentage given is traditionally expresses as relative humidity and is a comparison of the actual water vapor in the air versus the total amount that the air can hold. As you may know from experience, warmer air has a higher capacity to hold water when compared to colder air. This is why the humidity levels are higher in the spring and summer months.
In your commercial building, there are a number of sources of water vapor. A few of these include activities like cooking and people breathing. On average, four individuals put out three gallons of water into the air each day, combined.
To keep the humidity levels at a satisfactory state within your building, you’ll need to consider the outdoor air temperature. This is important for maximum comfort, as well as to prevent condensation from causing damage to wood materials within the structure. The following chart displays recommended relative humidity levels based upon incremented outdoor air temperatures:
- 40 F………..45%
- 30 F………..40%
- 20 F………..35%
- 10 F………..30%
It is also important to remember that keeping the humidity levels above 50% can cause microbial growth such as mold. Always take this into consideration, as mold can have adverse affects on your building and on the people whom inhabit it. If you have problems with keeping any indoor area below the 50% level, the use of a dehumidifier will be required to obtain proper conditions.
Thank you for joining us for part one of this two part series today! Next time we will discuss indoor pollutants and how to create an environment without them. If you have more questions on either of these topics, feel free to contact the St. Peter’s area commercial HVAC service specialists at American Services!
According to many within the HVAC industry, there are three main trends within HVAC today. These three trends include green initiatives, indoor air quality (IAQ), and emergency preparedness. Today, let’s take a look at how these three trends will play into your commercial HVAC service near O’Fallon!
When those in the HVAC industry talk green initiatives, most of the chatter revolves around the improvement of environmental air quality and the reduction of energy consumption. Improvements in these areas aren’t new to the industry, as both have been improved greatly in the last century thanks to advances in the areas of heating, AC, and ventilation. Yet, even more advancements are set to reduce heating and cooling loads even further – including the use of glass tinting to better regulate interior air temperature.
The next area that is trending within the industry revolves around indoor air quality. As homes and businesses continue to utilize better materials that seal-off outdoor air, concern for the air we breath continues to rise. This is a very valid concern and will require technicians to emphasize the need for proper ventilation while still utilizing energy efficiency upgrades. Look for a more advancements that will help with the monitoring and adjustment of indoor air quality in response to this issue.
Finally, emergency preparedness is an area that, if ignored, can cost businesses thousands of dollars in damage to structures, loss of productivity, and equipment replacement. The HVAC industry has realized this area of concern and has started to respond with solutions that will temporarily support equipment in a way that should remove the dangers mentioned above.

Thermostats are an integral component of any refrigeration system as they measure and regulate the temperature. Thermostats act like a light switch, turning on or off the flow of electricity to the refrigerator’s compressor. As a compressor runs the temperature will drop inside of the refrigerator and when the thermostat turns off the compressor, the air will try to warm up to the outside air.
There are a few different options when selecting thermostats for commercial refrigeration units. The three main types are air sensing, pressure sensing, and evaporator coil sensing. Air sensing thermostats are most prevalent in commercial refrigeration units. This type of thermostat will measure the return air in the refrigerator. Air-sensing thermostats will use a straight liquid or gas filled capillary attached to a bulb. The varying pressures with the temperature will open and close the electric current that controls the compressor.
Pressure sensing units are located outside of the evaporator housing near the compressor. The refrigerant which is circulated in the refrigerator and the pressure of that fluid is associated with the temperature inside the refrigerator. The thermostat will utilize the pressure as a means of regulating power to the compressor.
Evaporator coil sensing thermostats measure the temperature of the evaporator coil rather than the air or refrigerant. If a refrigerator is frequently opened or closed, the air temperature can fluctuate tremendously and create frost on the evaporator coil. Air sensing thermostats would not register the frost buildup causing the system to run inefficiently. The evaporator coil sensing thermostat allows for the correction of that problem.

American Services knows that ice machines are a necessity for customer satisfaction and productivity in your operation. Purchasing a new ice machine can be an exciting experience and a relief to know that your operation can continue providing a service to your customers. Although restaurant equipment is expensive you can save a little money by installing your new ice machine yourself. There are just a few basics to understand to ensure your ice machine will function properly once installed.
The most important decision will be the location of your commercial ice machine, which should be free of airborne and other contaminants. For safety and sanitary reasons, you do not want foreign matter to transfer to the ice. The air temperature must also be considered. Air temperature between 35 degrees Fahrenheit and 110 degrees Fahrenheit will ensure your system runs efficiently without overheating, or freezing up. Additionally, you do not want the location of your ice machine to be hear heat-generating equipment or in direct sunlight. Specifically, do not place it next to ovens, steamers, grills, or steam tables. This will cause your system to overwork itself in an attempt to keep the ice cold inside of the machine. An overworked machine will reduce the life of the components and increase the number of repairs required throughout the year. Additionally, the location you choose must not obstruct air flow through or around the ice machine. Air cooled equipment will require larger clearance measurements around the system where as water cooled ice machines will allow the machine to fit within a more confined space. Additionally, always check the electrical requirements to ensure your location can accommodate the ice machine.
