🔥 Think it’s hot outside? Imagine working in a 130°F attic.

When your AC goes out during a heatwave, HVAC technicians may be climbing into attics and crawlspaces where temperatures can reach 130°F or more.

While you’re enjoying that first blast of cold air after a repair, remember the technician who just crawled out of one of the hottest places in your home! 🫶

💙🧡 Thank you to our HVAC technicians who go where it’s hot so the rest of us can stay cool!
