Dave Dietz and Cole Zimmer enjoy working together and visiting operational job sites, including today’s F-16 aircraft tour at the world’s largest F-16 combat wing. Military and government projects have represented a significant portion of work for our tradespeople in recent years, and they are looking forward to their newest upcoming project. It’s amazing how our small family business, which started in rural Grant, MI, has grown into a national and specialized contracting firm—still family-owned and delivering projects ranging from residential homes to large, complex contracts.

A few tips to get ready for the extreme weather this weekend. It maybe around -15 degrees at night this weekend.
1. Change your air filter
2. Make sure your vents outside are not covered with snow.
3. Make sure you have enough gas.
4. Set your thermostat a few degrees warmer the day before.
5. Get an electric heater. Furnaces aren’t designed to work to this cold of weather, an electric heater will help add heat to your house.
6. Call us this week before it gets bad, if you have issues.
7. Check on your neighbors

Please do not wire in portable generators to your new modern furnaces or boilers. Modern equipment electronics require clean and constant 120 volts and if it varies you can fry electronics. We are getting these calls. It also voids your warranty.

If you’re stuck at home during this storm please change your air filter. Be safe out there!

Today was a successful day! One of our teams had the pleasure of giving two groups from a local school a tour of a mechanical project. Mark of the Z Heating shared insights into the uniqueness of the project and engaged with the students through a Q&A session. This initiative was intended to help students learn more about the trades as a potential career path.
