☀️ Let's face it: our heaters took a bit of a vacation during last year's "non-winter."

But as we know all too well, Colorado weather loves throwing surprises our way. With a potentially more active winter ahead, it's important to make sure your system is ready to hit the ground heating when the first cold front blows in. ❄️

As you turn your heater on during the first chilly nights of fall, pay attention to these signs that your system may need an inspection:

⚠️ Strange sounds
⚠️ No heat (obviously)
⚠️ Increasing energy bills

If you notice any of these issues, it could indicate that your heating system needs a repair or tune-up.

Get in touch with our team to schedule an inspection so you can enjoy the snowy season in comfort!

A long weekend at home + a failing AC unit = an end-of-summer memory nobody wants 🥵

While we’re enjoying the final weeks of summer weather, don’t forget to prep for the season ahead! ❄️

Snow days and sub-freezing temps are just about the last things on people's minds right now. But the best time to schedule a tune-up of your furnace is before the colder months hit–not after.

When you're proactive about your heating system, you'll be able to address potential issues before they take a toll on your comfort. That sets you up for:

😌 A stress-free winter season
💲 A lower chance of surprise repair bills
⚡ Higher energy efficiency (and lower utility costs)

D&A is here to make sure your heating system is in top form for the Colorado winter. Call us today for an inspection! 📞 (303) 834-3393
