Most auto and diesel repair shops operate without air conditioning in their service bays. While office areas are typically cooled, technicians are left working in physically demanding conditions, exposed to the heat and distressful conditions.
However, it’s not just about discomfort—high temperatures come with serious risks, from dehydration and heat exhaustion to burnout and injuries. Even in regions where extreme heat isn’t the norm, summer temps can creep up and create dangerous conditions.
High heat affects more than just your employees and their health. Occupational Health & Safety reports productivity drops by about 1% for every degree the temperature rises above 77°F. That hits your shop’s bottom line.
To help, we’ve put together simple, shop-friendly tips and a free poster for you to hang in your shop offering reminders to stay cool, safe, and productive when the summer heat rolls in.
7 Ways to Help Technicians Beat the Summer Heat
Here are a few simple, shop-friendly ways to help your technicians beat the heat and stay at the top of their game.
Place Fans Strategically
Use portable shop fans or evaporative coolers to keep air moving through work areas. Position them in shaded spots and at key airflow points to avoid just pushing hot air around.
Offer Cold Drinks & Treats
Set up a hydration station stocked with water, electrolyte drinks, and maybe even some frozen treats. Take a note from Woody Anderson Ford, who brought a Kona Ice Truck right into the service bay—a simple, appreciated morale boost.
Be Flexible with Break Times
When temperatures spike, it’s smart to ease up on rigid break schedules. Encourage and support your staff to take short, frequent cool-down breaks to avoid overheating.
Adjust Work Schedules, When Possible
If the weather forecast looks brutal, consider starting shifts earlier or moving heavier jobs to cooler parts of the day. It might feel tough to reschedule customer work, but taking care of your team ensures customers get quality work without risking anyone’s health.
Educate Your Team
At the start of extra-hot days or the start of a heat wave, gather the team for a brief safety talk. Cover expected temperatures, signs of heat exhaustion, and remind everyone to speak up if they aren’t feeling well. Look out, and take care of each other.
Stock the Essentials
Keep essentials on hand like electrolyte powders/drinks, cooling towels, extra bottled water, cold packs, sunscreen, or a shop thermometer to monitor bay temperatures. It’s a small move that can prevent big problems.
And Finally… Don’t Rule Out A/C
Yes—even if you’ve dismissed it before, give purchasing A/C for the shop another look. Even small, independent shops have found ways to air condition their service bays, and it’s often more affordable than you’d think. Run the numbers and research your options before ruling it out entirely—it could be a smart long-term investment in your team’s health, morale, and productivity.

Working in a hot shop isn’t just uncomfortable—it can be dangerous. Staying safe and productive starts with smart habits and a well-prepped shop. Help keep safety top of mind by posting these reminders around your shop.
Stay Hydrated
Drinking water consistently throughout the day is key. Aim for small sips often rather than chugging large amounts all at once. Electrolyte drinks like sports drinks or electrolyte packets mixed with water help replace what you lose sweating. Avoid too many energy drinks or coffee—they might give you a quick boost, but they actually dehydrate you faster.
Use Cooling Towels or Vests
Keep a cooling towel on hand to drape around your neck or wipe your face and arms during breaks. These help regulate your body temperature and provide instant relief. An evaporative cooling vest on the hottest days is also a good option.
Use Portable Fans or Evaporative Coolers in Your Bay
Set up fans or portable evaporative coolers in high-traffic and high-heat areas. Position them to create airflow through the bays and push hot air out. Even a small personal fan aimed at your workstation can make a noticeable difference.
Listen to Your Body & Take Breaks
Don’t push through warning signs. If you feel lightheaded, nauseous, unusually tired, or get muscle cramps, stop immediately. Find a cool spot, hydrate, and rest until you feel steady. Look out for your teammates too!
Wear Breathable, Light-Colored Clothing
If your uniform allows it, go for lightweight, moisture-wicking fabrics that help sweat evaporate and cool your body. Short sleeves can be helpful for airflow, and avoid dark colors, which absorb more heat.
Take Advantage of Cool Areas
Don’t underestimate the value of a shaded spot or air-conditioned break room. By taking regular breaks away from the heat, you are allowing your body to recover and preventing exhaustion.
Don’t Skip Meals or Snacks
It’s easy to forget to eat when you’re busy, but heat and physical work burn through energy fast. Keep light, healthy snacks like fruit, granola bars, or trail mix nearby to help maintain steady blood sugar and avoid fatigue.
