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.

We love our furry family members - but your HVAC system might have a slightly different opinion. 🤣

Pet hair, dander, and dirt can build up faster than you think, clogging filters and reducing airflow throughout your home. That means your system has to work harder to keep things comfortable… and that can lead to higher energy bills and more wear and tear over time.

If you’ve got pets at home, here are a few simple ways to keep your system (and your air) in top shape:
✔️ Change your air filter more frequently
✔️ Vacuum vents and around returns
✔️ Keep up with regular HVAC maintenance
✔️ Consider air quality solutions for cleaner air

Cleaner air = happier pets, healthier homes, and a system that runs more efficiently. 🙌

Spring has sprung… and your HVAC system is waking up from its winter nap.

Here’s your quick to-do list:
✔️ Change your air filter (yes, that one 👀)
✔️ Clear leaves/debris from your outdoor unit
✔️ Test your A/C before the first hot day hits
✔️ Check your thermostat settings
✔️ Schedule your spring maintenance

Skip it now, and your A/C might decide to take its own vacation in July… and trust us, it won’t send postcards. 😅
