What is a NATE Certified HVAC Technician?

What is a NATE Certified HVAC Technician?

Questions And AnswersThe professional HVAC technician you hire to install, service, and maintain your equipment should meet the highest of standards and for many that means having the NATE certification.  Today, the American Services HVAC team near Hazelwood will answer some common questions about this certification and tell you why it’s so important. Let’s get started!

What does NATE mean?

NATE stands for North American Technician Excellence and is a certification organization for heating, ventilation, air conditioning and refrigeration technicians.

What does the North American Technician Excellence organization do?


NATE was founded in 1997 and is headquartered in Arlington, VA.  NATE only tests HVACR technicians, it does not train.  When taking the NATE certification test, a technician is tested on his or her real world working knowledge of HVACR systems.

Is there just one NATE certification, or can a technician have multiple certifications?

Technicians participating in NATE certifications will take a Core Competencies test that covers the fundamentals of electricity and heat transfer.  They can also choose areas of specialty in which they will be tested.  These areas can include: Air Conditioning; Air Distribution; Heat Pumps; Gas Heating; Oil Heating; Hydronics Gas (service only); Hydronics Oil (service only); Light Commercial Refrigeration (service only); Commercial Refrigeration (service only); Ground Source Heat Pump Loop Installer; and Senior HVAC Efficiency Analyst.

Why is NATE testing important?

Organizations like NATE do a number of things to regulate the HVACR industry.  Testing like that provided by NATE makes quality the norm and ensures customer satisfaction, along with contractor professionalism.

When looking for area HVACR technicians that take professional development seriously and put customer satisfaction at the forefront, look for the NATE certification.  At American Services we ensure that all of our professionally trained technicians understand the importance of on-going training and encourage then to do so.  This makes our customers happy and our work the best in the area!



Quality Refrigeration Sytems Can Be Built to Fit Custom Spaces

Quality Refrigeration Sytems Can Be Built to Fit Custom Spaces

refrigeration systems in MOWalk-in coolers and freezers are a necessity for refrigeration in industrial needs for commercial and restaurant industries. Having a quality cooler or freezer will ensure your product stays fresh and safe until it is needed.

Most walk in coolers and freezers consist of assembled panels that have inner and outer metal skins with an insulated core.  Coolers and freezers can be built to fit a custom space, or pre-ordered from a standard template depending on your application.  Oftentimes a non-traditional space has been converted into restaurant kitchen or product storage area and a cooler or freezer needs to fit in an unusual location.  Other times, standard size cooler and freezer specs are provided to the architect during the initial design of the facility.

Refrigeration systems in Saint Louis must have a quality locking system with an emergency release from the inside.  Heavy-duty gaskets are a must to ensure an air tight seal between refrigeration panels and between the door and door jamb.

The insulation quality is measured in R-Value.  R-Value is the resistance to heat flow through an object.  The higher the R-Value, the better rated the insulation is.  By law, coolers must have an R-Value of R-25 and freezers must have an R-Value of at least R-32.  This has been set by the EISA.  Typical insulation used is either polyurethane or extruded polystyrene.  There are benefits to each type of insulation for various applications.  The best cooler or freezer for your commercial business will need to be at the recommendation of a professional refrigeration technician’s assessment of your location.

High Tech Refrigeration Systems Maintenance

High Tech Refrigeration Systems Maintenance

refrigeration maintenance in MOAmerican Services refrigeration service knows that a specifically designed flat panel refrigeration unit with a built-in freezer, the Sub Zero refrigerator, is an extremely efficient cooling unit. The difference in the high tech units is that they have no visible door hinges and line up flush with the existing cabinetry.

These high tech refrigerators have been designed to consume less energy than traditional refrigerators.  They are available in a variety of shapes and styles, with an optional glass front door. Sub Zero refrigerators differ from traditional refrigerators in that they also contain an extra layer of insulation and sealing rubber that keeps the cold trapped inside the device, resulting in longer lasting food.  These units are the most efficient appliance rated by refrigerator technicians.  These refrigerators are not immune to problems, therefore preventative maintenance should become a daily scheduled routine.

Condenser Fan and Dust Accumulation

One problem that may encounter during routine maintenance inspections with your Sub Zero refrigerator is an accumulation of dust on and around the appliance’s condenser fan and housing this is normal. However, if left unattended, excessive dust will cause the fan to fail prematurely, as well as the compressor-the refrigerator’s main cooling element.  This can also severely restrict unit longevity. Certified refrigeration technicians from American Services recommend that condenser fans need cleaning each time the appliance is serviced- multiple times throughout the year.

Drain Pan Leaks and Flooding

Leaking drain pans contribute to appliance flooding.  This can happen in either its freezer or refrigerator compartments. The leak develops near the refrigerator’s drain hole due to the hole being plugged or freezing over. The freezing water can inhibit the refrigerator from cooling and operating properly. Simple maintenance inspections will help prevent costly repairs.

The Sub Zero refrigerator’s door switch not only controls the light inside the appliance, but also controls the unit’s fan on/off function. This fan control switch keeps the Sub Zero refrigerator cooling and working efficiently. The door switch is prone to failure(due to repeated use) and can lead to spoiled food, inefficient unit operation, and the appliance’s compressor having to work harder under load and subsequently failing.

Save Energy Costs on Commercial Walk-In Cooling Systems

Save Energy Costs on Commercial Walk-In Cooling Systems

commercial cooling service in MOAmerican Services heating and cooling services in Saint Louis MO knows that one of the best ways to insure energy efficient refrigeration performance is knowing when maintenance  issues are minor or major.  Hiring a certified cooling and refrigeration technician yearly to inspect your system can teach you a lot.

One way to save on energy costs is to purchase strip curtains for walk-in units to minimize the amount of hot air entering the cooler .Do not allow staff to leave cooler doors propped open for extended periods of time, this causes condensers to work much harder than normal.  In some instances a simple “Keep Door Closed” sign can be part of the easy solutions performed by the owner or staff saving additional energy costs on utility expenditures.

Another common infraction that can be an easy solution to fix is to remind employees to turn off the lights when they exit the walk-in. Not only do the bulbs waste energy when the cooler is empty, the lighting also produces heat which causes the condenser to work harder to maintain a cool temperature. In addition, try replacing regular bulbs with fluorescent bulbs in the cooler. They give off less heat and are more energy efficient and less likely thaw products in the walk-in refrigerator.

Train all managers not to set the holding temperature too low on units because that will overwork the equipment. Walk-in coolers should be kept between 35 and 40 degrees and freezers between -5 and 5 degrees. Inspect periodcally and make sure all cracks are properly sealed and replace worn gaskets. Do not stack anything around the coil; this restricts airflow and decreases the performance of your cooler and decreases condenser longevity.

Set defrost frequency at minimum requirements (every four to six hours for 20 to 40 minutes depending on the amount of traffic in your walk-in).

With a little direction, your staff can play a contributing role in properly maintaining refrigeration equipment. These simple preventative measures can save restaurant owners a great deal of money in energy and repair bills, a help to avoid costly breakdowns.
