“What do HVAC technicians do all day?” asks every aspiring tradesperson before enrolling in a pre-apprenticeship program. While you know you’ll be fixing furnaces, refrigeration systems, and AC blower fan units, you might be curious how a typical workday pans out in the HVAC industry.
In this blog, we look at the daily responsibilities of an HVAC technician, including the challenges and scenarios they may encounter. Find out what to expect in your on-the-job training when you start your HVAC career.
While most HVAC technicians work on a variety of tasks, the average professional follows a fairly standard routine.
HVAC technicians are early risers, often starting before sunrise. Many successful HVAC technicians use this time to review local HVAC codes and prepare for the day ahead.
Upon arrival at the office, technicians review their schedules for the day. These can include service calls, installations, and maintenance checks. Before leaving, they review inventory to ensure they have all the necessary HVAC tools and equipment for each job.
Because an HVAC technician spends much of the day travelling between job sites, a valid driver's license is a standard requirement. Once set, they load their service vehicle with tools, diagnostic equipment, and replacement parts such as filters and thermostats.
The day’s first appointment may see an HVAC technician arrive at a house for routine maintenance. The technician greets the customer with excellent customer service, listening as they explain their air quality concerns.
With their troubleshooting skills and technical expertise, the technician uses diagnostic tools to detect potential problems with HVAC systems. This may involve inspecting electrical circuits, measuring fluid levels, or diagnosing electrical and mechanical faults.
If the technician identifies an issue, they perform the appropriate repair. A simple fix could be adjusting a thermostat, while a more complex task could involve repairing HVAC components, such as a heat pump motor, or performing warranty services.

After lunch, the technician might drive to a client who needs more than preventive maintenance. This could be a commercial HVAC job involving complex air conditioning systems that are not blowing cold air.
In these cases, customer service skills and providing technical knowledge to the client help ensure customer satisfaction.
Wiggling through a variety of work environments, such as a tight crawl space or crowded basement, the technician accesses the unit to test the run capacitor. Once replaced, they hear the blower whir. The technician then tests the air conditioning to ensure the temperature split is correct and the air quality is optimal.

The end of the workday arrives fast. An experienced HVAC technician might complete a tune-up that involves flushing and cleaning the unit to improve energy efficiency. They document all work and schedule follow-up appointments for any emergency repairs that require more parts.
After wrapping up, they return to the office, check emails, and restock their service vehicle.
Experienced professionals might handle final items, such as updating notes, to ensure all jobs were completed properly. Keeping tools organized is also a fundamental HVAC technician task that ensures a tradesperson is prepared for success the following day.
Unless the technician is called in for emergency repairs on short or no notice, it’s lights out at the office.

Absolutely. While the structure is similar, you can expect variations in HVAC technician requirements as seasons change.
During the summer, technicians work almost exclusively with air conditioners and cooling systems. This involves cleaning units, replacing dirty filters, and checking airflow. No one wants to sleep in a sweltering bedroom in the middle of July because their air conditioning system is not up to the task.
In winter, heating, ventilation, and air quality systems require more attention. Technicians are often called to inspect furnaces and heat pumps and test HVAC systems to ensure they’re functioning properly and efficiently.
