If you are looking for a career in high demand with strong salary potential and a near-permanent shortage of qualified technicians, HVAC is worth a serious look. The trade is one of the steadier bets in the U.S. labor market right now, and the 2024 Bureau of Labor Statistics projections back that up: HVAC technician employment is forecast to grow 8% from 2024 to 2034, much faster than the average for all occupations.
Before making any decisions, weigh the pros and cons of the path. This guide walks through what the work entails, current 2026 pay data, what licensing typically looks like (using Ohio as an example), and the realistic upsides and downsides.
What Does an HVAC Tech Do?
An HVAC technician installs, maintains, and repairs heating, ventilation, air conditioning, and refrigeration systems. The work spans new installs, warranty service calls, emergency repairs, and seasonal preventive maintenance. Customers range from homeowners and small business owners to large commercial operators, hospitals, and industrial facilities.
Day-to-Day Responsibilities
- Installing, maintaining, and repairing HVAC and refrigeration systems and equipment
- Identifying maintenance risks on existing equipment
- Diagnosing electrical and mechanical faults
- Cleaning, adjusting, and repairing systems, including warranty service
- Performing emergency repairs promptly and efficiently
- Providing technical direction and on-the-job training to apprentices
- Keeping daily logs and records of maintenance work
- Ensuring compliance with manufacturer specs and OSHA requirements
- Following service standards, work instructions, and customer requirements
- Handling customer questions and providing repair recommendations
HVAC Pros and Cons
Now that you know what an HVAC technician does day-to-day, here is the honest case for and against the trade.
On the plus side, HVAC is one of the most reliable career paths in the skilled trades. Demand is high, the work cannot be outsourced, and modern energy-efficient equipment plus an aging stock of older homes and buildings keeps the install and replacement pipeline full. According to the U.S. Bureau of Labor Statistics, HVAC technicians earned a median annual wage of $59,810 in May 2024.
On the other side, the work can be physically demanding. You will be on your hands and knees in tight spaces, lifting heavy equipment, and working in attics in summer and basements in winter. Basic math, electrical theory, and refrigerant handling all matter. Below is a more detailed breakdown.
Pros
- High demand for technicians. The Bureau of Labor Statistics projects HVAC technician employment will grow 8% from 2024 to 2034, much faster than the average for all occupations. About 40,100 openings are projected each year over the decade, driven by both growth and replacement demand as older techs retire.
- Strong salary potential. The 2024 BLS median wage was $59,810, with the top 10% of earners making more than $91,020 and the bottom 10% under $39,000. Pay scales upward fast with experience, certifications, specialty work like gas, hydronics, or commercial refrigeration, and ownership.
- Attractive compensation including overtime. Emergency calls, holiday work, and busy season overtime stack on top of base pay. If you are willing to take on after-hours work, your effective pay rate climbs quickly.
- A career with real growth potential. Technicians who complete formal training, earn certifications, and gain experience can advance to lead, supervisor, or service-manager roles, or open their own business. Sales and project management roles are also common destinations.
- Year-round work. HVAC systems run year-round, so technicians stay busy in every season. Cooling demand peaks in summer and heating in winter, but maintenance, installation, and replacement work fills the shoulder seasons.
Cons
- Working in uncomfortable conditions. Tight crawlspaces, hot attics, freezing rooftops, and exposure to dust, fumes, and refrigerants are part of the job. Personal protective equipment helps, but the work is physical.
- Risk of injury. Cuts, burns, electrical shocks, and back strain from lifting equipment are real occupational hazards. Following safety protocols and using the right PPE matters.
- Long hours and on-call work. HVAC techs often work evenings and weekends, especially in busy season. Many operations run on-call rotations to handle 24-hour emergency service for commercial and high-end residential clients.
What Does HVAC Pay?
As covered above, BLS data for May 2024 puts the national median annual wage at $59,810. Salaries vary based on experience, geography, certifications, the type of work, residential vs. commercial vs. industrial, and whether you work as an employee or run your own business.

Licensing in Ohio
Licensing rules differ by state, but Ohio is a useful example because the state distinguishes between contractors and apprentice technicians clearly.
To legally perform heating, air conditioning, and refrigeration work as a commercial contractor in Ohio, you must hold a state-issued contractor license. To work as a technician under that contractor's supervision, you do not need a state license at the apprentice level. The basic requirements to be an HVAC technician apprentice in Ohio include:
- High school diploma, GED, or equivalent
- One or more years of HVAC experience and willingness to continue training
- Valid driver's license
- Solid grasp of air conditioning, refrigeration, and heating principles
- Working knowledge of boiler systems
- Comfort with balancing air and water treatment systems per HVAC protocols
- Strong written, verbal, and interpersonal skills
- Ability to read schematics and work plans
- Willingness to work after hours, weekends, and holidays on short notice
The Ohio Construction Industry Licensing Board (OCILB) issues state contractor licenses for HVAC commercial work. After several years of qualifying experience, technicians can sit for the contractor exam, get licensed, and start their own businesses. Cities like Cleveland, Columbus, and Toledo, along with other local jurisdictions, have additional registration requirements, so always check the rules where you plan to work.
Types of HVAC Licenses in Ohio
Ohio has one statewide HVAC license: a Commercial Contractor license issued by the OCILB. HVAC tradespeople can learn the craft and work under a licensed contractor without a personal license.
The OCILB issues commercial contractor licenses for the Electrical, HVAC, Refrigeration, Plumbing, and Hydronics trades through the OCILB eLicense Center. According to ServiceTitan's Ohio HVAC licensing guide, the steps to get an Ohio HVAC contractor license are roughly:
- Be at least 18 years of age
- Be a U.S. citizen or legal alien (proof required)
- Have either at least five years of trade experience immediately before applying, three years of construction-industry business experience as a registered Ohio engineer, or other experience the board accepts
- Have no disqualifying offenses on your record
- Complete a state and federal background check after board approval, before sitting for the exam
- Pass the trade exam
- Carry a minimum of $500,000 in contractor liability coverage
- Pay the applicable fees
Several benefits come with completing this process.
Benefits of Having an HVAC License
- Open your own HVAC business. A contractor license is the gate to running your own HVAC business, hiring techs, and bidding commercial work in your name.
- Increased earnings potential. Licensed contractors generally earn meaningfully more than unlicensed techs, both per job and per year.
- Job security. Demand for licensed contractors is consistently high, especially given the wave of retirements in the trade.
- Improved career prospects. A license lets you bid on larger projects and partner with established commercial property owners and general contractors.
If you are seriously considering an HVAC career, do your homework on your state's specific licensing rules before committing.
