What to Consider When Choosing One of the Best Online HVAC Certification Programs

Choosing the best online HVAC certification program is not simply a matter of choosing the cheapest option or the class with the shortest completion time. Students will want to find an accredited institution that offers a high quality of education in the class format, length, and price range that works best for them. Students will also want to ensure the program prepares them for any licensing and certification exams.

Class Format and Course Length

To choose the ideal program, students will want to consider how long a course will take to complete and the format in which it is taught. For example, some online schools offer live instructor-led sessions, while others provide self-paced lessons that allow students to log in and complete the course on their schedule. Different methods of instruction are more effective for specific students, so it’s essential to find a suitable class format.

Classes can range from a couple of months to about a year, depending on the class format and how quickly the student goes through each lesson.

Cost and Financing

When choosing from online schools for HVAC, the cost will play a significant factor in the decision. Depending on what a student is looking to get out of the school, an online certification program could cost between $800 to $3,000. However, resources such as textbooks and vouchers for taking certification exams are included in the tuition price for some programs. It’s also important to remember that online courses will typically be much less expensive than in-person ones: HVAC trade school could run as much as $15,000.

Some schools offer financing so students can enroll and pay for the course on a schedule instead of making a lump-sum payment at the beginning of the class. Many HVAC professionals find that they can quickly make back the money spent on these courses. As technicians elevate their careers as professionals, they can charge more for services as a result of their advanced knowledge and experience in the industry.

Certification and Licensing Preparation

Before choosing a school for HVAC certification, students should be aware that they will not automatically receive a license or certificate when they complete these courses. Instead, the course prepares students for the certification and licensing process. In most states, the fee for a license is around $100 to $300 for the initial license, followed by a $50 to $150 renewal fee per year. States individually regulate what kind of licensing and certifications HVAC technicians require. When choosing the best online HVAC training program, students should compare the program to their state’s requirements to ensure it will be relevant to their needs.

However, HVAC technicians must obtain standardized nationwide certification to work with air- conditioning installation, commercial refrigeration, and climate control systems. The EPA Section 608 Technician Certification authorizes HVAC service providers to work with refrigerants. The best online HVAC programs will prepare students for this exam, and many will provide an exam voucher as part of the student’s tuition. Students can also boost their credentials by obtaining certifications from organizations such as North American Technician Excellence (NATE).

School Accreditation

Finding the best online HVAC school requires looking at the school’s accreditation. Students should seek programs accredited by a third party. This signifies the school’s curriculum has been evaluated by an outside organization that finds it meets educational standards. Accredited schools must also uphold accreditation, so students can trust that classes from accredited institutions are consistently updated. The Distance Education Accrediting Commission (DEAC) is a common accrediting body for online programs. International Accreditors for Continuing Education and Training (IACET) is another accrediting body students may see, particularly for institutions that offer continuing education credits.

The best online HVAC programs will differ based on each student’s ideal learning method, financial situation, and state requirements. To ensure we offer the top choices for HVAC certification programs, we thoroughly reviewed each program and considered many factors to showcase only the best options. Below are our top picks for the best HVAC certification programs.
