What does an HVAC Technician do?

HVAC technicians install, maintain, and repair heating, ventilation, air conditioning, and refrigeration systems. They keep homes comfortable in winter, businesses cool in summer, and ensure that hospitals, data centers, and grocery stores maintain precise temperature control. Every building with climate control relies on skilled HVAC technicians.

Daily Responsibilities

• Install heating and air conditioning systems in new construction and existing buildings
• Diagnose malfunctions in HVAC equipment using electrical testing instruments and gauges
• Perform preventive maintenance including cleaning coils, checking refrigerant levels, and replacing filters
• Connect systems to fuel and water supply lines, air ducts, and electrical wiring
• Test systems for proper operation and adjust controls for optimal performance
• Read blueprints, design specifications, and manufacturer instructions
• Handle and recover refrigerants in compliance with EPA regulations
• Repair or replace worn components including compressors, motors, fans, and thermostats

Work Environments

• Residential - Installing and servicing furnaces, central air conditioners, heat pumps, and ductwork in homes
• Commercial - Maintaining large-scale HVAC systems in office buildings, hospitals, and schools
• Industrial - Working on refrigeration units, chillers, and climate control systems in factories and warehouses
• Retail and Food Service - Servicing walk-in coolers, freezers, and commercial refrigeration
• New Construction - Installing complete HVAC systems in buildings under construction
• Service Companies - Running service calls for repairs and emergency work

Physical and Mental Demands

HVAC work is physically demanding. You’ll carry equipment and tools to rooftops, crawl into attics and crawl spaces, and work in tight mechanical rooms. The job requires lifting components up to 50 pounds, working in extreme temperatures (hot attics in summer, cold rooftops in winter), and spending time on ladders and scaffolding.

Mentally, HVAC technicians must understand electrical circuits, refrigerant cycles, and thermodynamics. You’ll need to read wiring diagrams, calculate heat loads, and troubleshoot complex systems where multiple components interact. Strong diagnostic reasoning is essential for identifying the root cause of system failures.

Personality traits that fit

• Analytical thinker - Diagnosing HVAC problems requires systematic troubleshooting
• Mechanically inclined - Understanding how electrical, mechanical, and refrigeration components work together
• Detail-oriented - Incorrect refrigerant charges or wiring can damage equipment or create safety hazards
• Customer-focused - You’ll work directly with homeowners and building managers
• Physically capable - Comfortable working in tight spaces and carrying heavy equipment
• Self-motivated - Many technicians work independently on service calls

HVAC certification and license types

HVAC technicians need EPA certification to handle refrigerants and may need state or local licenses depending on where they work. Here’s the certification hierarchy:

Note: EPA Section 608 certification is federally required for anyone who purchases, handles, or disposes of refrigerants. Most states also have additional licensing requirements. Always check your state’s specific HVAC licensing rules.

EPA 608 Certification Types

Step-by-step path to becoming an HVAC Technician

HVAC offers solid pay, steady demand (6% growth), and multiple specialization paths. It’s a good fit if you enjoy hands-on problem-solving, can handle physical work, and want a skilled trade with year-round employment and a clear path to business ownership.

Is it hard to become an HVAC technician?

HVAC combines mechanical, electrical, and refrigeration knowledge, so there’s a meaningful learning curve. The electrical and refrigeration theory can be challenging, but it’s learnable with dedication. The physical demands and working conditions are the biggest day-to-day challenges.

How much do HVAC apprentices make?

HVAC apprentices typically start at 40-50% of journeyman wages - roughly $15-$20 per hour depending on location. Pay increases each year of the apprenticeship, reaching 90-95% of full wages by the final year.

What certifications do HVAC technicians need?

At minimum, you need EPA Section 608 certification (required by federal law to handle refrigerants). Most employers also prefer or require NATE certification. Your state may require a specific HVAC license. Manufacturer certifications from brands like Carrier and Trane can also boost your employability and pay.

Can I become an HVAC technician with a criminal record?

In most cases, yes. HVAC licensing boards generally focus on relevant offenses. However, since technicians enter homes and businesses, some employers run background checks. Contact your state licensing board for specific guidance on how a criminal record may affect licensing.

Am I too old to become an HVAC technician?

No. Many people enter the HVAC field in their 30s, 40s, and beyond. Prior mechanical, electrical, or construction experience is valuable and can shorten your training path. The main consideration is physical ability to handle the demands of the work.

What is the difference between HVAC and HVACR?

HVAC stands for Heating, Ventilation, and Air Conditioning. HVACR adds Refrigeration. In practice, most HVAC training programs and technicians work on refrigeration systems as part of their scope. The BLS classifies the occupation as “Heating, Air Conditioning, and Refrigeration Mechanics and Installers.”
