Commercial Cooling Control Systems Save Money!

Commercial Cooling Control Systems Save Money!

Thermostat PanelAll small business owners are looking for easy ways to save on energy costs, especially as we approach the summer months of the year.  To help with this task, the professionals at American Services wanted to share three control system upgrades that can be utilized to do just that, save you money on your energy bills.  All of these control systems help to ensure your HVAC equipment is only being used when necessary and can be installed on both new and older units.  Let’s get started with our three examples.

  • Programmable Thermostats – Installing a programmable thermostat is the easiest, most cost-effective way to ensure the proper use of your HVAC unit.  When you switch to a programmable thermostat, you can control when your building is heated or cooled – usually by day of the week and time of day.  For example, if you are only in your office from 8 am to 5 pm, a programmable unit will allow you to keep the office at a comfortable temperature during work hours and then cool it down or warm it up when no one is there.
  • Multiple Zones – Dividing your facility into zones is a way to cool or heat only the areas of your building that are being used during specific times of the day.  This allows you to keep only the occupied areas of your building cooled or heated, while others are not.
  • Demand or CO2 Sensors – This new technology allows your system to measure the amount of CO2 present and regulates air quality based on those readings as opposed to the old assumed occupancy model.

If any of these systems are something you would like to utilize in your commercial building, contact the Fenton area commercial cooling installation experts at American Services for a free quote today!

Indoor Air Pollutants and Your Indoor Air Quality

Indoor Air Pollutants and Your Indoor Air Quality

Pollution Free SignYour commercials building’s indoor air quality is measured by the combined comfort your HVAC system provides in the areas of temperature, humidity, and air cleanliness.  Last time, we discussed the topic of humidity and outlined some facts that can assist business owner’s in achieving the right relative humidity for maximum comfort.  Today, let’s cover the basics regarding indoor air pollutants.

As many have already heard, the air within a structure can often be much more contaminated by pollutants than the that which we breath outdoors. Within a building’s air there are particles, chemicals, and tiny organisms that cause a decrease in overall quality.  One of the most common pollutants found indoors is Radon.

If these factors are bad enough, the health effects one experiences are referred to as Sick Building Syndrome.  You will know if you are experiencing Sick Building Syndrome because your symptoms will only be present in a certain building and will dissipate once you leave.  Symptoms of this type of sickness include eye irritations, nose, irritations, throat irritations, allergic reactions, headaches, various cancers, fatigue, issues with concentration, and sensitivity to odors.

So, how do your improve your indoor air quality?  First, minimize the amount of household chemical you use, don’t allow smoking indoors, and  limit the use of any unvented appliances.  Next, improve your overall ventilation by replacing some of the building’s inside air with fresh air from outside.  Finally, look into air cleaning methods that remove chemicals from the air with activated charcoal.

Thank you for joining us for our discussion on pollutants and indoor air quality.  The team at American Services hopes this information will assist you in creating that most comfortable environment within your commercial building.  For more information concerning heating, cooling, and refrigeration services near Belleville, contact your American Services customer service representative today!

Your HVAC System’s Role In Indoor Air Quality

Your HVAC System’s Role In Indoor Air Quality

maintenance repairman 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!

Keep Your Restaurant Refrigerator Clean With These Tips!

Keep Your Restaurant Refrigerator Clean With These Tips!

open refrigerator Cleanliness is a top priority for restaurant owners, especially in the kitchen.  When properly cleaning your commercial kitchen, it’s important to remember the areas you might not thing of.  Like the inside of your refrigeration units.  Today, let’s go over some easy tips you can use to keep your refrigeration units clean and fresh.

First, look at the outside of the unit.  Does it need a little attention?  If so, use a damp cloth and mild dish soap to clean the exterior.  Make sure to use non-abrasive materials to prevent scratching.  This is especially true when working with units made of stainless steel. Clean with the grain of the metal and make to sure to remove any remaining cleaning solution residue with a clean cloth at the end.

Next, you’ll need to remove all items from the unit.  Take the time to clean the inside of the unit with the same solution you used above.  If you happen to notice a foul odor, you’ll need to address that as this time also.  Make sure all the food being stored in the unit is fresh and remove anything that you can no longer use.  You can help prevent future odors by placing an open box of baking soda into the cleaned unit.  If that doesn’t help, consider a cleaning alternative like a mixture of water and vinegar.

Now that your unit is clean, you can replace your cold items for storage.  Keep your refrigeration units clean by repeating this process as necessary and immediately removing spills when they happen.

How Does An HVAC System Work?

How Does An HVAC System Work?

ThermostatYour commercial HVAC system controls the movement, quality, and temperature of the air within your building.  The system you have will behave in a repetitive cycle to maintain the quality of the environment you want.  Here are some basic HVAC components that allow that to happen.

Air Intake – This part of the system brings outside air into your building using a fan, thus providing fresh air to the system.

Air Handling Unit – This part of the system is responsible for filtering and adjusting the temperature of the fresh air that is taken in.

Supply Ducts – Your supply ducts take the filtered and cooled or heated air to the locations around your building.  You will find these on the floor or on the walls of your building.

Return Ducts – Your return ducts act in a contradictory way to your supply ducts.  Their job is to take the old air out of a room and recycle it in your Air Handling Unit.

Exhaust Ducts – This part of your system takes any excess air and removes it from the system.  You will find your exhaust ducts at the end of your HVAC system between the return ducts and Air Handling Unit.

Your commercial HVAC system is a very complicated unit.  These are just the basics of how a standard unit functions.  Please consider always using a professionally trained HVAC company for all of your HVAC related service, parts, and maintenance.

Efficient Cooling Strategies For Your Small Business As Outlined By the EPA

Efficient Cooling Strategies For Your Small Business As Outlined By the EPA

Air conditioning repairThe team at American Services always has your best needs in mind.  This includes providing the tools needed to maintain a cost-effective system that saves you money with simple, everyday strategies.  Today, let’s take a look at a few energy saving tips as outlined by the EPA.

  • Don’t waste money by forgetting to turn off lights and equipment while not in use.  This will not only save you money on your overall energy bill, but will additionally keep rooms cooler by reducing the amount of heat being omitted by any lights or equipment that is being used.
  • Use “occupant sensors.”  Occupant sensors are designed to sense when someone is in a room and will automatically turn on the lights for them.  These sensors will also then turn the lights off once the room is no longer occupied.  This type of technology is inexpensive, easy-to-install, and will save you from accidentally keeping the lights on.
  • Ask the small business cooling experts at American Services about purchasing ENERGY STAR labeled HVARC equipment.  This equipment meets certain standards that will help you save money on usage.
  • Ask about units that have a “stand-by mode” or a “sleep mode.”  These two functions are designed to reduce the “vampire” effect of equipment that is always on, and thus, always draining power.
  • Make sure you are having regular HVAC “Tune-up” services performed.  This type of service is best maintained with an annual contract that outlines the proper upkeep of all of your HVACR-related equipment.  When thinking about what kind-of contract will work best for you, always look to the professionals.  These individuals will understand the needs of your equipment and will work with you on affordably creating the right contract for your individual needs.

Calculate the Heat Loss On Your Commercial Building

Calculate the Heat Loss On Your Commercial Building

CalculatorUnderstanding the heat loss you are experiencing can help in understanding issues you may have with improper insulation, old weather-stripping, and worn-out windows. These factors play into the efficiency of your commercial heating system and can cost you money.  Today, let’s take a look at how you can calculate how many BTU’s, or how much heat loss, you’re commercial building is experiencing.

First, you’ll need to do some measuring.  Get the length, width, and height of each room that you wish to calculate heat loss on.  You’ll need to get the surface area of the floor, ceiling, and the walls of each room in question.  Make sure you record these measurements and continue to record the calculations you make.  It’s also important to remember that more multipliers can be found by researching on the web.

Roof Heat Loss Equation 

  • Ceiling Area  X  Multiplier for Building Material Used  =  Heat Loss Through the Roof
  • Glass and Corrugated Asbestos has a multiplier of 5.7
  • Sheet Asbestos has a multiplier of 6.5
  • 25 mm wood has a multiplier of 5
  • 100 mm of concrete has a multiplier of 4

Walls Heat Loss Equation

  • Wall Area  X  Multiplier for Building Materials Used  =  Heat Lost Through the Walls
  •  140 mm insulation block has a multiplier of 1.1
  • Corrugated double cladding with 25 mm of fiberglass over polyethylene vapor barrier has a multiplier of 1.4

Floor Heat Loss Equation 

  • Floor Area  X  Multiplier for Building Material Used  =  Heat Lost Through the Floor
  • Earth Floor has a multiplier of 1.9
  • Concrete Floor has a multiplier of 0.7

To get the total BTU loss (per hour) for the building in question, you will need to do the calculations for all the rooms in your building and then add them together.

Effectively heating your commercial building may not seem as important now, since warmer months are upon us.  But doing a quick energy audit now can save you come Fall.  If you believe your commercial heating system near South County is in need of some updating, contact American Services for a free quote today!

Commercial Refrigeration In the Modern Grocery Store

Commercial Refrigeration In the Modern Grocery Store

Produce CaseWalk into any modern grocery store and there’s not doubt the serious commercial refrigeration work that has been done.  Your grocer wants to provide you with a product that looks appealing, is at it’s peak of freshness, and keeps you and your family safe.  That’s where the commercial refrigeration experts come in. Hiring the right team of professionals ensures that all of your needs are met, while saving you money with the latest, high-efficiency units.

Two simple ways of breaking down the cases you’ll see at your supermarket is by categorizing them as open or closed-door:

  • Open Cases – Open cases use curtains of air to separate contents from the open air. For example, some freezer cases will use three curtains of air to ensure proper cooling.
  • Closed Door Cases – Instead of using a curtain of air, a closed door case seperates product from ambient air with a physical door.

Here are a few examples of what temperatures and other specifications you’ll find various types of cases being used at:

  • Produce Cases – Produces cases are medium temp and must maintain a temperature of 35 to 38 degrees to keep contents fresh.
  • Flower Cases – A case that displays flowers will not only need to ensure that the product stay cool, but will also keep the air full of humidity.
  • Fresh Fish – This type of product needs to be in a refrigerated ambient case, in addition to being placed on a bed of ice.
  • Dairy Cases – Dairy cases need to be at the same specs as a produce case, between 35 and 38 degrees.
  • Beer Cases – Beer needs to be kept at 37 degrees – the perfect temperature for serving.
  • Deli Meats and Cheeses – Deli meats and cheeses are considered a ready-to-serve product and should be stored at 32 degrees.
