    HVAC installers, HVAC service technicians, and refrigeration technicians are mechanics who set up, maintain, and fix heating, ventilation, air conditioning, and refrigeration equipment and systems that control indoor temperature and air quality. The types of equipment they work on may include (but are not limited to) air conditioners, heat pumps, blowers, fans, variable frequency drives, boilers, thermostats, humidistats, timers, belts and pulleys, condensate drain lines, compressors, heat exchangers, and walk-in or lowboy refrigerators.

    HVAC installers focus on putting in and connecting the equipment so that it is operational, while HVAC service technicians focus on maintenance and repair once the systems are installed. Refrigeration technicians work primarily on systems that cool or sustain air temperature at a desired value. In HVAC/R companies with about 30 or more employees, job duties tend to be differentiated into those roles. Smaller companies are more likely to hire technicians whose responsibilities include all aspects of HVAC/R installation, maintenance, and repair.

    Emerging electricity-based HVAC/R systems are more technologically complex than traditional systems that use fossil fuels, and they are becoming more common. Therefore, while these workers’ daily tasks are expected to remain similar to tasks performed on oil or gas burning systems, they will need additional training to master the mechanics of clean energy systems (i.e., variable refrigerant flow systems, ducted and ductless air source heat pumps, and ground source heat pumps) and smart (automated) mechanical systems. Retraining may also be needed for workers to safely handle the refrigerants with low global warming potential that are expected to become more commonplace in the next few years.

    Workers who install HVAC/R systems need to be able to interpret schematics, wiring diagrams, and sequence of operations, and do so with an attention to detail that ensures the installation of both hardware and software is completed in accordance with manufacturer’s specifications. They connect pipes and tubing and check for leaks, install ductwork, set up low voltage wiring to connect system controls to equipment (as permitted by local licensing regulations for electrical work), and inspect, test, and balance the system to ensure it is operating properly. Servicing the systems involves performing preventive maintenance (e.g., replacing filters, cleaning drain lines or ducts, removing and replenishing refrigerants), inspecting parts and controls, and testing the system to determine if it is running efficiently. If it is not, technicians troubleshoot and diagnose the issue, repair or replace malfunctioning mechanical or electrical components, and calibrate the system. 

    HVAC/R installers and service technicians use math skills to calculate the rate of airflow and heating and cooling loads. HVAC/R systems are becoming increasingly automated, and workers may be required to manage service requests electronically, so they should be comfortable using computers, tablets, and smartphones. Physical requirements for these jobs include the ability to stand or walk for extended periods, climb ladders, crouch or otherwise access low spaces, and lift materials weighing up to 75 pounds. Manual dexterity and good vision are necessary. Because of the physical nature of these jobs, regular use of tools, and exposure to refrigerants, HVAC/R installers and service technicians must follow safety procedures and comply with government codes and regulations to minimize the risk of injury.

    Organizational skills are needed to properly maintain an inventory of supplies and order more as needed, keep the company vehicle orderly (if applicable), and document any supplies used and work performed when fulfilling service requests. HVAC/R installers and service technicians should have strong teamwork, communication, and customer service skills to have positive interactions with managers, helpers, vendors, and customers. They need to be able to explain the work that is necessary to improve system performance. Experienced technicians may train more junior employees and be responsible for supporting sales by providing price quotes and identifying potential contracting opportunities.

    HVAC/R installers and service technicians typically travel between worksites, which can include residential or commercial properties. They may specialize in either type of HVAC/R system, depending on their personal preference and company’s size (i.e., larger employers tend to have differentiated roles). Work schedules are usually full-time, often require being on call for emergencies, and can include early mornings, evenings, weekends, and holidays.   

    Job Outlook

    According to the New York State Department of Labor, there are approximately 16,700 HVAC/R installers and service technicians in New York State and opportunities for employment are expected to be very favorable through 2028 – the Department projects this occupation to grow by 2,290 jobs between 2018 and 2028.

    Entering the Field

    HVAC/R installers and service technicians typically need to have a minimum education of a high school diploma or GED, and many employers prefer to hire workers with specialized training including vocational training, a trade certificate, associate degree, or relevant apprenticeship program. Entry-level jobs may be available to candidates without any experience and the skills needed to become a proficient installer or service technician are often learned on the job over a year or more while working alongside a more experienced employee. Senior technician positions do require about seven years of relevant work experience.

    HVAC/R workers who handle refrigerants must have U.S. Environmental Protection Agency Section 608 Technician Certification. Local governments may also have licensing requirements for individuals who install and service HVAC/R systems. For example, New York City requires an Oil Burning Equipment Installer license for anyone doing that type of work. A valid driver’s license is necessary for jobs that require traveling between worksites. 

    Employers may prefer to hire individuals who have certifications issued by HVAC/R industry organizations that demonstrate competence in general HVAC/R installation, maintenance, and repair or specialized services and equipment such as those related to electrified systems. Examples include certifications by NATE, ACCA, RETA, ESCO Group, the Building Performance Institute, Inc. (BPI), and manufacturers’ certifications for specific equipment.

    Check local government requirements for more information regarding eligibility to work as an HVAC/R installer or service technician. Also, check job ads and with local employers to understand which industry certifications are valued for different HVAC/R positions.


    In New York State, the median wage for HVAC/R installers and service technicians is approximately $60,700. Entry-level workers earn about $41,600 and experienced workers earn about $76,200. Those who have expertise in electrified energy efficient technologies (e.g., heat pump installers and technicians) will likely earn salaries at the higher end of this range, particularly as demand for these types of technologies continues to increase.
