Learn the Heating and Cooling Trade

HVACR is a broad field that covers working with a variety of appliances and equipment. This can includd heaters, ventilation systems, air conditioners, and refrigerators. At New England Tractor Trailer Training School, we do more than just CDL training. Our HVACR technical trades division teaches and helps to prepare students with career training in the field of HVACR maintainance and repair.

Our HVAC courses are available at our North Andover, Massachusetts school as well at our Pawtucket, Rhode Island school. These classes have a hands-on approach to learning so that students can get first-hand experience with the tools and equipment. Through our HVAC classes, students will be trained on how to install, adjust, and maintain these different appliances and systems under the supervision of an experienced instructor. We train students on both commercial and household equipment so that they can leave our school and pursue the path they feel most comfortable with. This can range from new equipment installation, to current system maintenance or repair. In addition to our hands-on training,  our students have access to online 3-D simulation labs for extra support. If you like solving problems and working with your hands, then HVAC training may be just for you!

HVACR includes training on a variety of different appliances. Training at our school  focuses on the following areas within HVACR:

Here in New England, heating is a must. Students will learn about different heating systems such as oil furnaces, electric heating, commercial gas systems, and steam hydronics.

Air distribution is key to keeping things warm in the winter and cool in the summer. Our HVAC course will teach you about this complex system and how to create a proper balance while learning how to do so with the tools and equipment that is used in the field.

Air conditioning has become a necessity for many houses and businesses in the United States. From home rooftop units to central air systems in commercial buildings, students will be trained on the different air conditioning units, how they work, and what it takes to keep them running.

Not only does nearly every home rely on a refrigerator, but so do millions of businesses like restaurants, supermarkets, hotels, and pharmacies. Our refrigeration school courses will teach you how to keep all these commercial and residential units running properly.

With our HVAC repair classes, students will be introduced to the basics of electricity. This means practical electrical principles like Ohm’s Law, series-parallel circuits, and DC/AC are discussed along with how they apply to HVACR systems.
