Anyone else turn on the heat and AC in the same week? That’s Colorado. 😂❄️☀️

Wanted to share this with you guys. If you’ve got a coat you don’t wear anymore or warm clothes the kids have outgrown, someone could really use them this winter.

Daniel’s Giving Tree is collecting new and gently used winter clothes, and I’d love to help get the word out. Drop-off info is on the flyer. Appreciate anyone who can donate a few things or pass this along. ❤️

Cold mornings, shorter days, and a little more time indoors. ❄️ As Colorado heads into winter, a warm home gives us a comfortable place to unwind, gather with family, and leave the chill outside.

Grab a blanket, pour something warm, and enjoy the little things that make home feel like home. 🏡☕

That coat you don’t wear anymore could help someone stay warm this winter. 💚

Your furnace might turn on—but is it ready for a Colorado winter? 🥶 Here are 3 reasons to get it checked:

🔧 Catch problems early. Find small issues before they turn into a breakdown on a freezing night.

🔥 Keep it running efficiently. A dirty or struggling furnace can work harder to keep your home warm.

🏠Check for safety concerns. An inspection can help identify issues with venting and components that affect safe operation.

📞 Call **720-767-6326** to schedule your furnace check!
