Most Affordable Online HVAC Trade Schools & Certifications for 2025

Co-Founder and Chief Data Scientist

Many Americans today opt out of earning a 4-year college degree mainly due to financial constraints. Notably, in 2023, 54% of workers ages 25 to 34 lacked the credential (Fry, Braga, & Parker, 2024). Many of these individuals enter the workforce earlier than college graduates do, including workers with heating, ventilation, and air conditioning (HVAC) education and training from online HVAC trade schools.

Because of the demand, HVAC professionals in the US have a higher median annual wage than that of all occupations across the country. To help you get started on your HVAC career, I created this guide to online HVAC trade schools. Explore courses, tuition, and income potential below.

What are the benefits of getting an online HVAC education and training?

Education and training from online HVAC trade schools can help you land several jobs in the field, including heating, air conditioning, and refrigeration mechanic and installer; electrician; stationary engineer and boiler operator.
In May 2024, heating, air conditioning, and refrigeration mechanics and installers in the US had a median annual wage of $59,810, which is higher than the $49,500 median annual wage of all occupations in the country in the same period [US Bureau of Labor Statistics (BLS), 2025].
A major benefit of completing an HVAC program online is the flexibility to learn at your own pace while balancing work or family commitments, without sacrificing hands-on training opportunities.
