Overview

Granite State Trade School has been providing specialized mechanical-trades education in New Hampshire since the mid-2000s. The school began with natural-gas and propane training and became the state’s first independent training provider and testing proctor for gas licensing through the Office of the State Fire Marshal.

Today, Granite State offers a broader lineup covering HVAC, plumbing, gas licensing, oil-burner service and continuing education. Its model is particularly suited to adults who are already working or want to combine evening training with employment.

Unlike some short-course schools, Granite State also offers longer structured career pathways, including a two-year HVAC certificate and a four-year plumbing apprenticeship curriculum.

Current training areas include:

• HVAC Technician
• HVAC/R Certificate

HVAC Certificate Program

The program consists of:

• Four semesters
• 75 hours per semester
• 300 total instructional hours
• Two evenings per week
• 6:00–8:30 p.m. schedule

Current tuition is $1,975 per semester, or $7,900 for the complete certificate.

Online & Hybrid HVAC Training

Granite State also partners with the Plumbing-Heating-Cooling Contractors Association to provide an e-learning HVAC pathway.

Students complete online coursework through PHCC but must attend required mentoring sessions at the Raymond campus. The final examination must also be proctored according to program requirements. This makes the program genuinely hybrid, rather than simply an online lecture course.

Textbooks are separate and are currently listed at approximately $150 per level.

Plumbing Apprenticeship

Granite State also offers a complete four-year plumbing apprentice program, which is especially relevant to students already employed under a licensed plumber.

The school has expanded beyond entry-level training into continuing education and license advancement, making it useful throughout a tradesperson’s career.

Gas Licensing

Gas licensing remains one of Granite State’s core specialties. The school was an early independent provider approved by New Hampshire’s State Fire Marshal and continues to offer both initial training and license-renewal education.

Tuition & Financial Aid

Tuition varies by program.

The clearest current published figure is:

HVAC Certificate: $1,975 per semester / $7,900 total.

The school does not prominently advertise traditional FAFSA/Pell Grant funding. Apprentices should ask employers whether tuition reimbursement is available, since many skilled-trade employers contribute toward required education.
