After the wild weather we've had lately, it's a good reminder that heating and cooling systems can be affected when Mother Nature decides to put on a show.

No matter if it's storm-related power issues, an A/C unit that won't restart, or unexpected system problems after severe weather, Hillestad is here when you need us most.

🚨 We offer 24/7 Emergency Service because HVAC emergencies don't always happen during business hours.

Stay safe, Wisconsin, and remember: when the weather gets unpredictable, you can count on Hillestad.

When temperatures climb, your A/C works harder, and your energy bill can too. The good news? A few simple habits can help keep your home cool and your costs down.

✔️ Change your air filter regularly
✔️ Schedule an A/C tune-up
✔️ Use ceiling fans to circulate cool air
✔️ Keep blinds closed during the hottest part of the day
✔️ Set your thermostat a few degrees higher when you're away

A well-maintained air conditioning system runs more efficiently, uses less energy, and helps keep your family comfortable all summer long.

Don't let your utility bill be the hottest thing this season. 😎❄️

Team Hillestad was proud to sponsor a hole at the Lodi & Lake Wisconsin Chamber of Commerce Golf Outing earlier this week!

We had a great time connecting with fellow businesses, enjoying the course, and supporting our local community. The weather cooperated... for a little while.

Let's just say our golf game lasted longer than the sunshine before some massive storms decided to make an appearance. Fortunately, everyone stayed safe and we still enjoyed being part of a fantastic event.

Thank you to the Chamber for organizing another great outing! We'll try for that first place prize next year! 😅

Your pets shed. Your HVAC system notices.

Pet hair and dander can clog filters, reduce airflow, and make your system work harder than it needs to.

If you've got furry family members at home, be sure to check your filters regularly and keep up with maintenance.

Your pets, and your HVAC system, will thank you.

Summer weather is officially here, and your A/C is about to become the hardest-working appliance in your home.

Before the hottest days arrive, make sure your system is ready to keep you cool and comfortable. A preventative maintenance visit now can help improve efficiency, prevent breakdowns, and extend the life of your equipment.

Don't wait until the first heat wave hits!

When the temps rise, so can your energy bill - but a few simple changes can make a big difference.

Here are some easy ways to keep cool without breaking the bank:
✔️ Set your thermostat a few degrees higher when you’re away
✔️ Change your air filter regularly
✔️ Use ceiling fans to help circulate cool air
✔️ Keep blinds/curtains closed during peak sunlight
✔️ Schedule an A/C tune-up to keep things running efficiently

Skipping maintenance might save you time now… but your energy bill will definitely notice later. 😅

Stay cool, save money, and let Hillestad help keep your system running at its best all summer long.
