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

If your AC use has taken a toll on your wallet this summer, here's a money-saving tip for August:

❄️ Don't turn your AC off when leaving the house!

According to Trane, repeatedly turning your system off and on can actually use more energy and increase your utility bills.

Plus, if you let your home turn into an oven during the day, your system will have a much harder time cooling it down when you get back.

Instead, simply set the thermostat at a higher temperature while you're away. This way, you're not wasting cold air on an empty house—but you're also not letting the temperature rise unchecked.

Think a garage can't make for a cozy home office? Think again! ✨

Last year, our technicians helped transform a customer's garage into a dedicated workspace. While the homeowner was busy selecting the right furniture and decor, we got to work installing a furnace, AC, tankless water heater, and ductwork to keep the garage comfortable year-round.

Ever adjust your building's thermostat or HVAC schedule for a certain season or event–only to forget to turn it back?

Regularly reviewing your property's HVAC schedule helps ensure you're not throwing energy out the window. Here's what that means for your property:

⚡ Less waste
💲 Lower utility costs
⚒️ Reduced wear and tear

Updating your HVAC schedule is just one way to cut down on energy costs. Routine maintenance can also help your system run efficiently year-round.

💡 One more reason to invest in whole-system maintenance:

HVAC issues often have more than one culprit!

That's what our team found when inspecting a failing air conditioner at a customer's home. Not only was their condenser coil extremely dirty, but an issue with the furnace was also preventing the AC from starting up.

After we cleaned the coil and got the AC back online (with the help of our trusted Trane product), the system was officially ready to take on the Colorado heat.

☑️ Another hassle-free service in the books!

Want to make sure your AC works smarter, not harder? ❄️

When you turn on your unit this season, make sure the doors and windows in your home are fully closed and sealed.

This will help your home cool down faster, use less energy, and keep your utility bills lower.

That's a win-win-win!
