Tempstar Spotlight: comfort + reliability ❄️☀️

When it comes to home comfort, your HVAC system should do more than turn on and off. It should keep your home feeling steady, efficient, and comfortable through every season.

That’s where Tempstar comes in. Designed with reliability and total home comfort in mind, Tempstar heating and cooling systems help homeowners enjoy consistent temperatures, dependable performance, and peace of mind when the weather outside is doing its thing.

Because comfort should feel easy, not like a daily negotiation with the thermostat. 😄

Smoky skies are hard on indoor comfort too. 🌫️

During wildfire season, your home or building can feel stuffy, dusty, or heavy if outdoor smoke starts affecting indoor air quality.

A few simple steps can help:

✅ Keep windows and exterior doors closed

✅ Check or replace your HVAC filter

✅ Keep vents and returns clear

✅ Avoid bringing smoky outdoor air inside

✅ Ask about filtration options that suit your system

Indoor air quality matters, especially when the air outside is less than ideal. Sub Zero can help you review your system and find practical ways to keep your indoor air more comfortable.

Myth vs Fact: Turning the A/C way down cools faster ❄️👇

MYTH: Setting your thermostat super low will cool your home faster.

FACT: Your A/C cools at the same rate either way. Dropping the temperature way down usually just makes the system run longer, work harder, and possibly overshoot your comfort zone.

Your thermostat is not a turbo button. 😄

For better comfort and efficiency, choose a steady setting, use a schedule when possible, and make sure your system is clean, maintained, and ready for the heat.
