3 Key Installation Tips to Remember After Your HVAC Technician Training

November 01, 2022

In recent years, we’ve seen record-high temperatures across the globe. Many homeowners are recognizing the importance of good ventilation and cooling units–and that’s where you come in as an aspiring HVAC technician. 

HVAC technicians are responsible for the installation, maintenance, and repair of heating, ventilation, and air conditioning systems. Here are a few installation tips to remember when installing HVAC units, and how our HVAC technician program can help you launch a successful career in this industry! 

1. Start by Determining Your Heating and Cooling Loads 

The heating and cooling load refers to the rate at which heat should be supplied to or removed from a space in order to maintain a particular temperature range. Several factors go into determining this like the location, size, and age of a home. In addition, you’ll need to take into account the materials that were used to make up a home, the number of doors and windows, the amount of direct sunlight, the amount of shade, and whether or not the homeowners have special needs due to allergies and other health conditions. 

After HVAC school, be sure to determine the heating and cooling load before installing a unit.

Once you’ve come up with this important information, you can go on to take a look at the ductwork that’s been done and make any needed repairs or replacements. As you’ll learn in HVAC technician training, poor ductwork can cause imbalances and, as a result, block airflow and decrease air quality. To boost your ductwork, you may consider adding insulation that can improve the performance of HVAC systems.

2. Be Sure That You’ve Chosen the Correct Sized Unit

A large unit is not always better. If a system is too large for a homeowner’s space, it actually becomes inefficient. In fact, systems that are too large for a particular space can experience degradation faster, which will affect the longevity and performance of the unit. That being said, a small unit wouldn’t be appropriate for a large space as it will not effectively heat or cool the space. 

How can you ensure that you’ve sized the unit correctly? First, determine the square footage of the space. Then, multiply the square footage by 25 BTU (British thermal units), the rough amount of energy it takes to heat or cool one square foot. This will give you your base BTU amount. Finally, take the height of the ceilings into account. If the ceilings are above 8 feet, multiply the base BTU amount by 1.25. This is a very basic calculation that does not take into account the climate, amount of people living in the home, or the number and placement of doors and windows. You’ll learn more about this process in HVAC school.

Be sure to calculate the base BTU amount to choose the right-sized unit for a particular space.

3. Make it a Habit to Check Your Lines After HVAC Technician Training 

Refrigerant lines connect an outdoor air conditioner or heat pump to the indoor evaporator coil. It’s essential to check these lines for leaks. If you find refrigerant lines that are in poor condition, be sure to run high-quality replacement lines in a location that provides easy access. In the HVAC Technician Diploma program at NATS, you’ll learn how to install and maintain HVAC systems and work with tools like metal snips, electric drills, testing devices, and more. Students can write their G3 gas technician exam after the first module and the G2 gas technician exam after graduation.

3 Things to Know About Checking Refrigerant Pressure After HVAC School

May 31, 2022

If you’re pursuing an HVAC career, one of your main responsibilities will be to service and repair air conditioning units. Along with other routine maintenance tasks, you’ll need to perform refrigerant pressure checks. Refrigerants are chemical compounds which absorb heat from the surrounding environment. During a refrigerant cycle, refrigerants will repeatedly change from a fluid to a gaseous state depending on their temperature, moving through the cycle’s components in order to reroute heat to other areas. Refrigerants are used mainly in air-conditioning systems, heat pumps, refrigerators, and freezers.

At NATS, you’ll receive hands-on training to pursue an HVAC technician apprenticeship, learning how to install and maintain gas and propane heating systems, air conditioning units, and ventilation equipment for both commercial and residential environments. Below, get a head start on your training by discovering a few key things to note about checking refrigerant pressure. 

Checking Refrigerant Pressure Requires an Understanding of the Refrigerant Cycle

As an HVAC technician, understanding the ins and outs of refrigerant pressure won’t be possible without basic knowledge of refrigerant cycles. Refrigerant cycles consist of four basic components: the compressor, condenser, expansion device, and evaporator. The compressor is what uses the most power in an HVAC system–responsible for compressing gaseous refrigerant in a cooler state to a high-pressure, high temperature vapour. From here, the refrigerant is cooled by the compressor, a coil filled with hot refrigerant which wraps around the system to diffuse heat. Next, the expansion device works to reduce the refrigerant pressure quickly to prepare it for evaporation. Evaporation will occur in the evaporator, which boils the refrigerant. Through these exchanges in energy and changes in matter, refrigerant regulates the temperature of a system.

As an HVAC technician, it’s important to understand how refrigerant cycles operate

What Condensing Pressure of a Refrigerant Means for an HVAC Technician

When refrigerant changes from a gas to a liquid within a cycle, this creates what’s known as condensing pressure; a form of condensation. This occurs when refrigerant moves through the condenser, releasing heat as its temperature drops to the temperature of condensation. The condenser is a cooling system composed of tubes which expand over a large surface area to remove the greatest possible amount of heat. The condensing pressure, which results from the release of heat and sudden drop in temperature, can be read by a pressure gauge. While this gauge can be placed anywhere between the metering device and compressor, it should be placed as close as possible to the condenser in order to obtain an accurate value. During your HVAC technician career, it’s important to remember that a higher-than-normal pressure could indicate problems with the condenser coil, broken or faulty fans, or even leaking refrigerant.

A pressure gauge is used to determine the condensing pressure

Evaporating Pressure is the Opposite of Condensing Pressure

When you enrol in HVAC technician courses, you’ll also become familiar with refrigerant’s evaporating pressure. A refrigerant’s evaporating pressure is the opposite of condensing pressure. During this phase, the refrigerant chemical compound is vapourized, changing from a liquid to a gaseous state and absorbing heat from its surroundings. When the refrigerant moves through the suction line and evaporator, the valve and line pressure drop. As with condensing pressure, the evaporating pressure can be read using a pressure gauge that’s situated and connected anywhere between the compressor and metering device. A refrigerant’s chemical compound enters the evaporator as a low pressure, cold liquid, but as it absorbs heat, it begins to boil and evaporate.

3 Common Challenges You May Encounter During Your HVAC Technician Career

April 19, 2022

For an aspiring technician looking to work in the HVAC industry, it’s important to know the common issues your customers may encounter that’ll require your expertise in repairing and resolving those issues. HVAC challenges can sometimes have simple solutions when it comes to repairs, but if not handled immediately and properly, they can cause further damages as well as more time and money to fix.

At NATS, you’ll gain hands-on training through our HVAC pre-apprenticeship program. You’ll learn how to install and maintain gas and propane heating systems, as well as ventilation and air cooling equipment for both residential and commercial environments. Your training will prove to be valuable to customers as you work on resolving common HVAC challenges.

Read on to find out the three common challenges you’ll face in your career!

1. As an HVAC Technician, You May Encounter Pilot or Ignition Issues

One of the common HVAC challenges you’ll encounter might have to do with the gas furnace’s pilot or ignition unit. When this issue is present, it prevents the furnace from dispersing any sort of heat around a unit or home, which can be a big problem in extreme cold weather conditions. 

Ignition problems for the furnace can be caused by dirty pilots or flame sensors. As a professional HVAC technician, you’ll have to examine these furnace components, as their malfunctioning can cause short-cycling, a pilot outage, delayed ignition of the furnace burners or an entire furnace lockout. You’ll have to assess whether the furnace components have experienced wear and tear over time and need replacement, or whether the issue is related to a gas supply problem. 

A common challenge you’ll encounter is problems with a furnace’s pilot and ignition components

2. Dirty Filters Are Most Common

After you complete your training from an HVAC school, you may get a call from customers regarding poor airflow circulation around their homes or offices. This is most likely related to dirty air filters. Dirty air filters are the most common HVAC challenges you’ll face during your career. However, they’re fairly simple to handle and resolve. 

A dirty filter will reduce the lifespan of a customer’s furnace because it places more pressure on the furnace to circulate air. It can also cause it to repeatedly overheat and shut off. You’ll have to replace the dirty filter with a new recommended filter based on its Minimum Efficiency Reporting Value (MERV) rating. The higher the MERV rating of the filter, the better it is for air quality. 

As an HVAC Technician, you’ll probably have to replace dirty filters

2. Wear and Tear of Heating System Components

Another common HVAC challenge you may come across during your career is complaints about the heating system’s ability to generate heat for an entire office or home. This can be the result of the wear and tear of some components in the heating system. You’ll have to check the heating system for the condition of its bearing and belts. You’ll probably have to check if the belts are stretched or worn out, and if they require replacing. Additionally, the heating system’s motors and bearings might not be well lubricated, and in that case, you’ll have to oil them to allow them to run smoothly.

If You’re Enrolled in HVAC Technician Courses, Discover 5 Signs of Low Refrigerant in a System

October 07, 2021

If you’re considering becoming an HVAC technician, you’ll be launching a career as an expert in the field of heating, ventilation, and air conditioning systems. Your expertise will enable you to perform services for clients such as installing HVAC systems, maintaining and repairing the systems, and troubleshooting problems within these systems. When servicing air conditioning systems during your career, one of the most common problems you may encounter is a low level of refrigerant within the system. 

Refrigerant, a compound which absorbs heat from the surrounding environment, is essential to the smooth operation of an AC system. Within an AC system, refrigerant is stored inside copper coils–taking in heat from the air in a home or other indoor space. The refrigerant is then distributed through the condenser and compressor, where it is converted from liquid to gas to liquid. The resulting hot air is blown outside, while another fan blows air over the cold coils containing the refrigerant and into the building. Given the importance of refrigerant in the distribution of cold air, when refrigerant levels are low, an AC system’s performance will be negatively affected. 

When refrigerant levels are low, it’s typically either due to a leak, or because the AC system was installed incorrectly. During your career as an HVAC technician, becoming familiar with the signs of low refrigerant in an AC system will help you to successfully identify and repair related issues before greater damage ensues. Below, discover five common signs of low refrigerant in an air conditioning system. 

1. After HVAC College, Look Out for Longer Cooling Cycles

If a client complains that it’s taking a particularly long time to cool their home, low refrigerant levels could be at fault. With low refrigerant levels, the air being blown indoors is warmer than usual, meaning that the air conditioning system has to run longer cycles to match the thermostat-designated temperature. After HVAC school, check the refrigerant levels of an AC system if the cooling cycles seem unusually long.

It may take longer for an air conditioner to cool a home when refrigerant levels are low

2. The Refrigerant Lines Freeze

Low levels of refrigerant can also have a negative effect on the AC system’s refrigerant lines, or evaporator coil. The evaporator coil is responsible for taking hot air from the indoors and adding it to the refrigerant. However, when refrigerant levels are low, the evaporator coil will become too cold, leading to a buildup of ice. Typically, this ice will start to spread to other parts of the AC system, including its surrounding components.

3. The Energy Bills Go Up

When a client complaining of higher energy bills requests your services, the air conditioning system’s refrigerant levels will be one of the first things you’ll want to check. Due to the longer cooling cycles which are needed to cool a home, the air conditioning system is working much harder than it should be. Since harder work translates to a greater consumption of energy, always remember to check refrigerant levels when a client’s energy bill spikes. 

A client’s energy bills will typically increase when there isn’t enough refrigerant

4. Lack of Cold Air

After HVAC college, it’s safe to suspect low refrigerant levels when an AC system isn’t blowing cold air. Because the cooling chamber contains more heat when refrigerant levels are low, it’s difficult for the system to adjust the temperature of the air it’s sending out. This causes the system to expel lukewarm rather than cool air–a problem which is more than inconvenient for those trying to keep their homes cool during the warmer months!

5. There’s a Hissing Noise

When refrigerant levels are low, one of the probable causes is a leak somewhere within the AC system. In the case of a leak, it’s likely that a hissing noise can be heard, indicating that refrigerant has escaped from the coils that contain it. The moment you hear a hissing sound coming from an air conditioner unit, check the refrigerant levels to ensure that there isn’t a hazardous leak.
