As extreme and dangerous heat envelops much of the country, HVAC technicians are still going to be on the front lines, providing relief to families and other sectors who need relief.
This vital service obviously comes with its fair share of dangers, as exposure to excessive heat can put even the most seasoned tech at risk.
In the midst of a heat wave, technicians must rely on their training, and each other, to stay safe.
Below are a few quick tips based on guidance from the Centers for Disease Control and Prevention (CDC) and the Air Conditioning Contractors of America (ACCA). But remember, when in doubt, contact a medical professional.
Recognizing Heat Illness Symptoms
When the body becomes too hot, it will begin exhibiting some tell-tale signs.
According to the CDC, these include:
- Muscle cramping
- Unusually heavy sweating
- Shortness of breath
- Dizziness
- Headaches
- Weakness
Some other signs may include slurred speech, nausea or vomiting, and rapid heart rate.
Seek medical care immediately if you or a coworker is exhibiting any of these symptoms.

ACCA suggests moving to a cooler location, getting some water, removing shoes, socks, and outer layers of clothing, and cooling off with ice or a cool, wet cloth.
ACCA also has a guide for other dangerous signs that may indicate someone is experiencing heat stroke. These include nausea, confusion, odd behavior, headache, high body temperature, hot, dry skin, and loss of consciousness. This is considered a serious medical emergency, and 911 should be called immediately.
Heat-impaired judgement can also appear before a technician even starts to feel “sick,” so it is also encouraged to take frequent breaks for prevention’s sake.
Hydration
While each situation/individual may vary, the CDC recommends drinking 8 oz. of water every 15-20 minutes during moderate activities in the heat. If sweating lasts for more than a few hours, sports drinks are recommended. Alcohol and drinks with a lot of caffeine or sugar should be avoided.
Acclimation
For new technicians, other than training, the CDC recommends an acclimatization schedule, in which the tech’s time in the heat is gradually increased over seven-to-14 days. For new workers, the CDC recommends no more than 20% of the usual duration of work in the heat on day one, and no more than a 20% increase on each additional day. For workers with previous experience, the schedule should be: no more than 50% of the usual duration of work in the heat on day one; no more than 60% of the usual duration of work in the heat on day two; no more than 80% of the usual duration of work in the heat on day three; no more than 100% of the usual duration of work in the heat on day four.
Other Suggestions/Prevention Tips:
Aside from some of the obvious ones, like drinking plenty of water and stopping if dizzy/faint, the CDC recommends sunscreen, wearing hats and light-colored, loose-fitting clothes, taking breaks in air-conditioned environments, encouraging coworkers to take breaks and hydrate, and scheduling tasks either earlier, or later, in the day to avoid the midday heat.
ACCA also suggests setting up a shaded area, if one isn’t available.
Today’s tech should also consider leaning in on technology, like the CDC’s Heat & Health Tracker, which provides localized information to help better prepare for heat events.
