November is here, and Wisconsin is officially entering the season of cozy blankets, warm drinks, and checking the thermostat approximately 47 times a day. 😂

As the temperatures start to drop, make sure your heating system is ready to keep your home comfortable all season long.

Here's to a warm and cozy November!

Happy Halloween weekend from all of us at Hillestad!

Stay safe out there, and make sure the only thing sending chills down your spine is a ghost at your door...not your furnace giving up on a cold Wisconsin night! 🥶😂

Forget vampires and zombies… HVAC pros have some truly chilling costume ideas! 😂

If your Halloween costume needs a little inspiration, try one of these spooky HVAC looks:

🧟 The Dirty Air Filter - Grab some gray fabric, add a little fake dust, and become every homeowner’s worst nightmare.

🥶 The Frozen Thermostat - Dress in blue, bundle up in scarves, and insist the house is still too cold!

👻 The Ghost of Furnaces Past - An old furnace technician who haunts homes with scary stories about neglected maintenance.

🔥 The Overheated Furnace - Red clothes, orange streamers, and a dramatic “I CAN'T TAKE THE HEAT!” meltdown.

🦆 Susie the Duck: HVAC Edition - A duck costume with a tiny tool belt, ready to make sure everyone stays cozy this winter!

And, of course, the scariest costume of all… a homeowner who forgot to schedule furnace maintenance! 😱

Have a safe and spooky Halloween from all of us at Hillestad Heating & Cooling! 🎃

We love a casual morning meeting to walk through a big install project!

It's so important to make sure everyone is on the same page before we head out for the day. Happy Monday!

If your furnace could talk, it might have a few things to say! Here are 5 things your heating system wishes you knew before Wisconsin winter really kicks in:

1. I need room to breathe! Keep vents and returns clear of furniture, rugs, and other obstructions so air can circulate properly.

2. Please change my filter! A dirty filter restricts airflow and makes me work harder than I need to. Check it regularly and replace it when it’s dirty.

3. Stop making me guess! Constantly adjusting the thermostat won't necessarily save energy. Find a comfortable setting and use a schedule that works for your household.

4. A little maintenance goes a long way. Annual professional maintenance can help catch small issues before they become bigger, more expensive problems.

5. Don't ignore my warning signs! Strange noises, unusual smells, or trouble keeping your home warm could mean it's time for a professional inspection.

Your furnace works hard to keep your family cozy all winter long. Give it a little TLC now, and it may save you some headaches when the temperatures drop! 🥶

Closing vents in rooms you don't use will save you money on your energy bill.

🤔 MYTH or FACT? 🤔

🥁 THE ANSWER: MYTH! ❌

It might seem logical to close vents in unused rooms, but your HVAC system is designed to distribute air throughout your home. Closing vents can disrupt airflow, create pressure imbalances, and potentially make your system work less efficiently.

Instead, keep your vents open and unobstructed, change your air filter regularly, and let your HVAC system do what it was designed to do!

No elevator? No problem!

It's a good thing we have William to help us in these situations!

Ghosts? 👻 Fine.
Witches? 🧙‍♀️ Fine.
A house full of sugar-fueled kids? 😳 Terrifying.

But a furnace that won't turn on when the temperatures drop? Now that's a real Halloween horror story.

Before the really cold weather arrives, make sure your heating system is ready to keep your home warm and comfortable all season long.

And if your furnace decides to pull a spooky surprise, Hillestad offers 24/7 emergency service to help get your home comfortable again.

Keep the scares at the front door this Halloween - not in the basement!

10/14/2026

Hearing some strange noises coming from the basement? Before you blame the ghosts, your furnace might be trying to tell you something!

👻 Banging?
👻 Rattling?
👻 Squealing?
👻 Clicking?

Your furnace shouldn't sound like it's hosting a Halloween party.

While some noises can be harmless, new or unusual sounds shouldn't be ignored. A strange noise could be a sign that your system needs attention, and catching a small problem early may help prevent a bigger one later.

So before you grab the Ouija board, give Hillestad Heating & Cooling a call.
