Note: With ServiceTitan’s field service management software, HVAC techs can note all safety considerations related to a customer’s premises in their file. These notes, inspection checklists, and even pictures of specific safety hazards (which the tech adds via the ServiceTitan Mobile app on a tablet while on the job) will be included in the customer’s job history. These details are immediately shown when a call is booked for that customer in the future.

1. Electrical Hazards

HVAC work requires handling electrical wiring. When on a job, techs must de-energize all equipment before performing routine inspections, tests, repairs, and other servicing procedures.

Avoid accidents with these electrical HVAC safety tips:

• Turn off power to the corresponding circuit in the breaker panel.

• Use proper lockout and tag procedures to ensure no one tries to turn on the power while you are working.

• Before performing the work, test the circuit with a meter that is properly rated for the type of circuit you’re testing to determine if it’s still energized.

2. Chemical Exposure

One of the main HVAC accidents the industry sees is exposure to dangerous chemicals and contaminants.

Technicians work with a variety of chemicals that can cause serious burns, such as refrigerants, cleaning liquids, solvents, and gasses. Even though a lot of refrigerants are classified as safe by the manufacturers, the chemicals’ toxicity is subject to increase when exposed to heat—ultimately reducing indoor air quality and posing a health hazard to technicians. Proper HVAC safety training is crucial before working with these chemicals.When handling hazardous materials, exercise caution and always gear up with reliable personal protective equipment (PPE), including safety glasses, protective footwear, and HVAC work gloves. Follow all safety precautions.Pressurized gas cylinders—commonly found on the back of a technician’s work truck—can become a fire hazard or even explosive when exposed to extreme summer temperatures. One bump on the road can send them shooting off like a rocket. For proper handling and storage, the American Welding Society (AWS) recommends the following:

• Secure cylinders upright with a chain or strap in a proper cylinder cart.

• Ensure valves are completely closed and any protection devices are secured.

• Keep cylinders in a ventilated location free from excessive heat and electrical circuits.

• Ensure safety measures, such as caps or guards, are securely installed.

• Use a cart or hand truck. Do NOT drag or roll cylinders.

3. Inadequate Equipment Inventory

Having the proper HVAC tools is crucial. Practice a routine of prevention and awareness. Before departing for your scheduled route, make sure the tools in your vehicle are ready for work. This way, you can arrive at the homeowner’s residence confident you have the properly functioning tools needed to complete the job.Additionally, determining which tools you’ll be using for your next job makes it easy to hit the ground running upon arrival. It’s not just about staying organized with your equipment inventory; it actually prevents you from improvising when you’re in the midst of a job. The best tactic for safety is prevention and proper HVAC servicing procedures. Read our related article for suggestions on how to check equipment before setting out on a call:

4. Respiratory HVAC Safety Hazards

The most common health risks HVAC technicians are exposed to are respiratory related. Many homes contain HVAC systems with dirty air filters that act as petri dishes for mold, bacteria, and fungus. A faulty pilot light and heat exchangers leaking on the furnace can lead to carbon monoxide poisoning.

Wear an industrial-grade face mask to prevent inhaling these lingering dangers in close proximity and for extended periods. Sometimes, the job requires a higher-grade mask, such as a cartridge-style mask or even a self-contained breathing mask—especially if the job is in a contaminated and confined space. Adequate airflow is paramount in these situations, and work should be carried out in an open space, whenever possible.

5. Ladder Liability

According to a CDC report, “each year in the U.S., more than 100 people die and thousands more are injured from ladder-related falls.” By taking a few extra steps to adequately secure your ladder, you prevent one of the most common instances of fatalities and injuries on job sites.

When engaging in ladder work:

• Always maintain three-point contact. Either both feet with at least one hand or both hands with at least one foot on the ladder at all times.

• Place the base of the ladder a quarter of its working length from the dwelling to achieve the safest angle.

• Make sure the extension or straight ladder extends at least 3 feet above the point of support.

• Ensure all locks are properly engaged on an extension ladder.

6. Dangerous Driving

All of your tools may be pristine and properly stored. You may be fully outfitted with all of the PPE you can manage to put on. You can climb a ladder safely and follow every precautionary step when dealing with electrical or chemical hazards. But none of that matters if you never make it to the job.

Daily driving is a mundane reality for virtually all HVAC technicians. But driving with care not only reflects positively on your company (let’s face it—that van is really just a moving billboard), it saves lives.

To stay safe on the road:

• Schedule enough time between jobs, so you are not rushing to get there.

• Always communicate with your dispatcher if your schedule is not feasible for your driving route.

ServiceTitan’s Route Optimization Features and Implications for Driver Safety

ServiceTitan’s dispatching features include route optimization—giving techs the most efficient route to their next job site. Route optimization allows technicians to complete more jobs in less time without compromising on safety. Plus, having automated driving instructions reduces stress and eliminates distractions for drivers.ServiceTitan’s route optimization feature automatically minimizes drive time by using average traffic speeds. It can optimize technician route schedules to take existing commitments into consideration, so you don’t have to remember every techs’ dental appointment, or scheduled afternoon off.

Daily jobs are completed in the most efficient order based on technician locations—plus, technicians never need to find the most efficient routes themselves.

7. Unprofessional Conduct

It’s an act of trust when a homeowner invites a technician into their home, and nothing screams unprofessional like an untrained technician. An untrained technician easily disrupts a homeowner’s sense of security. As a business owner, make sure all of your technicians receive HVAC safety training to recognize hazards and establish proper protocols to ensure the safety of both technicians and customers.

8. Extreme Weather Conditions

HVAC technicians frequently work outside in extreme heat or cold. This leaves them at risk for fatigue, dehydration, heat stroke, hypothermia, and frostbite. As an HVAC tech, know your limits, wear the proper clothing, hydrate, and take breaks as needed to avoid these conditions. If techs don’t take care of themselves and their co-workers, they can’t serve customers properly. A technician’s health is worth the time.

9. Technician & Client Health

As a part of their job, HVAC technicians touch various surfaces (door handles, thermostats, etc.). While there were fewer health risks associated with transmission before COVID-19, the pandemic cautioned us to take additional steps to ensure the health and safety of technicians and customers. And this remains a concern, particularly for those who may be classed as vulnerable. Simple safety strategies can help mitigate these ongoing risks.In situations where contracting COVID may still be a health concern, all transactions that can be completed virtually (like receipts and payments) should be done in advance to limit contact. For the actual visit, all employees should wear a properly fitted mask. Further, technicians should carry disinfectants for their hands and equipment and maintain a 6-foot distance. After completion of the job, all employees should wash their hands, or at least sanitize them until they have the option to do so. Understandably, any employee showing symptoms or facing health concerns should not be working. Following these cautionary steps can ensure that the technicians, as well as the customers, are fully protected and prepared.
