HVAC Technician

Field & Trades

Installs and services the heating, cooling, and ventilation systems that keep a building livable, one of the few trades with a federal certification requirement baked into the job.

What is a HVAC Technician?

An HVAC (Heating, Ventilation, and Air Conditioning) Technician installs, maintains, and repairs the systems that heat, cool, and ventilate a building: furnaces, rooftop units, ductwork, and increasingly building automation controls. Unlike most trades, working with the refrigerants used in most HVAC equipment isn't optional to certify for: federal law (the Clean Air Act's Section 608 rule) requires anyone who handles regulated refrigerants to hold an EPA Section 608 certification, so this is one credential nearly every HVAC technician earns early on, not just a nice-to-have.

What they do

Install ductwork, rooftop units, furnaces, and air handlers according to mechanical drawings
Charge, recover, and service refrigerant in cooling systems, following EPA-regulated handling procedures
Diagnose and repair failures in heating, cooling, and ventilation equipment
Test and balance airflow through a finished system before it's turned over
Read mechanical drawings and manufacturer specs to plan installation and troubleshoot problems
Coordinate with electricians and plumbers so rough-in work doesn't conflict in shared wall or ceiling space

A typical day

Pay expectations

Pay by experience, nationally

as of May 2025

Source: U.S. Bureau of Labor Statistics, Occupational Employment and Wage Statistics (OEWS), Heating, Air Conditioning, and Refrigeration Mechanics and Installers (SOC 49-9021), national data

Reviewed May 2025. Pay reflects the national wage distribution for this occupation, not a promise for any one job: entry level is the lower part of that range, 5 years in sits around the national median, and 10 years in is the upper part, since pay isn't actually tracked by years on the job. Real pay varies a lot by state, metro area, union status, and employer — scale these up or down for your market. These figures are base pay only: overtime, shift differentials, and per-project bonuses are standard across most construction trades and routinely push real earnings above what's shown here.

What this chart doesn't capture

An HVAC company's real upside often isn't the installs — it's the maintenance contracts that keep paying after the job is done.

These figures are wage-and-salary pay only — BLS excludes the self-employed and business owners entirely. No reliable owner-income figure exists for HVAC contracting specifically; most of what's online is marketing content, not real data. Recurring service and maintenance agreements are a common way HVAC companies smooth out the feast-or- famine swings other trades see — worth researching your own market before assuming a number holds.

Education

Required:: High school diploma or equivalent, then trade school or a registered apprenticeship (typically 3-5 years); an EPA Section 608 certification is legally required before working with regulated refrigerants, and a Journeyman HVAC license is legally required by most states/municipalities before working unsupervised
Helpful:: NATE (North American Technician Excellence) certification, and OSHA 10 or 30 (not a nationwide legal requirement, though several states, including New York, Massachusetts, Connecticut, Nevada, Missouri, and Rhode Island, legally require it for workers on public construction projects)
Not necessary:: A four-year college degree isn't part of this path; trade school or apprenticeship leading to licensure is the standard route
