🔧 Technician Tuesday Spotlight: Dan 🔧

This Tuesday we’re recognizing Dan after receiving a ⭐⭐⭐⭐⭐ review from Terry:

“Had my seasonal HVAC service done today by McNally's Heating and Cooling. Dan their service tech called 20 minutes prior and gave me his arrival time. He arrived right on time and got to work. He treated my home with respect and answered all of my questions in ways that I could understand. I would highly recommend McNally's along with Dan for any of your HVAC needs.”

Ready to make a visible difference in our community? Join us for our Community Cleanup Day this Saturday, April 18th, proudly sponsored by McNally's Heating and Cooling! 🌿🧤

Whether you have thirty minutes or three hours, your helping hands keep our local spaces beautiful and vibrant. It’s a great opportunity to connect with neighbors, get some fresh air, and take pride in where we live.

Event Details:
When: Saturday, April 18th

Time: Volunteer Kickoff Between 8-9am

Where: Volunteers can meet at the Chamber office at 427 W. Virginia St Crystal Lake IL

Groups can pick up supplies at the Chamber office while enjoying coffee and treats from The Salvation Army Crystal Lake Church of McHenry County

👥 Bringing a Group?
If you’re planning to come with a group of friends, coworkers, or a local organization, you can get a head start! Reach out to the Park District today to receive a specific park assignment before Saturday. This is a great way to ensure your team is all set to tackle a specific area together.

A huge thank you to McNally's for their support in making this event possible. There’s nothing quite like the feeling of looking back at a clean park and knowing you helped make it happen. It’s the perfect excuse to step away from the screens, enjoy the outdoors, and give back.
