The Importance Of HVAC Training


Individuals that provide homes and businesses with heating and cooling system installations and services need to make sure they have take HVAC training. The purpose of HVAC training is to educate technicians about the science of heating and cooling systems, as well as the proper methods of handling and installing these devices. If you are interested in HVAC training, then it is important to understand the types of classes that are part of the program.

Theory And Principles

In HVAC training programs, students will learn about the theories and principles that are used in a heating and cooling system. These details are important because HVAC training enables a technician to determine the size and installation method for a customer’s system.

Heat Transfer

The rate at which heat can transfer into a building will play an integral part in determining the size of the heating and cooling unit that is installed. In HVAC training, students will learn the subject of heat transfer and what role it plays in designing a quality system.


Any HVAC training program is not complete without a class in blueprints. Every heating and cooling system needs to have a plan that outlines its electrical diagram in detail. This will provide the technician with a roadmap of the wires and parts that must be interconnected. If a problem occurs with the system, a technician with HVAC training will be able to determine if the part needs to be replaced.


Many businesses rely on qualified individuals who have taken HVAC training to repair or replace their refrigeration systems. For instance, without a constant temperature, a business that sells perishable food items may have a total loss. With HVAC training, students will learn how to repair refrigeration systems so that the compressor is fully charged and the proper temperature can be maintained.

Designing A System

HVAC training programs will instruct a student on how to design the proper heating and cooling system for a home or business. Certain factors need to be considered, such as the amount of square feet that is being heated or cooled, the number of floors, the number of windows, and the overall energy efficiency of the home. This information will help the HVAC training technician complete the load calculation that will determine the size of the heating and cooling unit. If the technician did not have HVAC training, they would install a comfort system that would leave the home or business too hot or too cold.

Environmental Concerns

Technicians that provide heating and cooling services need to complete HVAC training to be familiar with the environmental guidelines that govern this field of work. Older cooling units have a coolant that can damage the environment, so it is necessary that the technician recover the gas safely.

HVAC training is a great education to have if you are looking to enter this profession. HVAC training is also beneficial to currently employed technicians so that they can remain informed about any new changes in the field.

How To Correctly Maintain Your AC Unit

An air conditioner's filters, coils, and fins require regular maintenance for the unit to function effectively and efficiently throughout its years of service. Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases.


The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace or clean its filters. Clogged, dirty filters block normal airflow and reduce a system's efficiency significantly. With normal airflow obstructed, air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil's heat-absorbing capacity. Replacing a dirty, clogged filter with a clean one can lower your air conditioner's energy consumption by 5% to 15%.

For central air conditioners, filters are generally located somewhere along the return duct's length. Common filter locations are in walls, ceilings, furnaces, or in the air conditioner itself. Room air conditioners have a filter mounted in the grill that faces into the room.

Some types of filters are reusable; others must be replaced. They are available in a variety of types and efficiencies. Clean or replace your air conditioning system's filter or filters every month or two during the cooling season. Filters may need more frequent attention if the air conditioner is in constant use, is subjected to dusty conditions, or you have fur-bearing pets in the house.


The air conditioner's evaporator coil and condenser coil collect dirt over their months and years of service. A clean filter prevents the evaporator coil from soiling quickly. In time, however, the evaporator coil will still collect dirt. This dirt reduces airflow and insulates the coil, reducing its ability to absorb heat. To avoid this problem, check your evaporator coil every year and clean it as necessary.

Outdoor condenser coils can also become very dirty if the outdoor environment is dusty or if there is foliage nearby. You can easily see the condenser coil and notice if dirt is collecting on its fins.

You should minimize dirt and debris near the condenser unit. Your dryer vents, falling leaves, and lawn mower are all potential sources of dirt and debris. Cleaning the area around the coil, removing any debris, and trimming foliage back at least 2 feet (0.6 meters) allow for adequate airflow around the condenser.


The aluminum fins on evaporator and condenser coils are easily bent and can block airflow through the coil. Air conditioning wholesalers sell a tool called a "fin comb" that will comb these fins back into nearly original condition.


Occasionally pass a stiff wire through the unit's drain channels. Clogged drain channels prevent a unit from reducing humidity, and the resulting excess moisture may discolor walls or carpet.


At the start of each cooling season, inspect the seal between the air conditioner and the window frame to ensure it makes contact with the unit's metal case. Moisture can damage this seal, allowing cool air to escape from your house.


In the winter, either cover your room air conditioning unit or remove and store it. Covering the outdoor unit of a central air conditioner will protect the unit from winter weather and debris.


When your air conditioner needs more than regular maintenance, hire a professional service technician. A well-trained technician will find and fix problems in your air conditioning system.
