Cooling FAQs

  • How often should I service my AC unit?

    We recommend a tune-up once a year, ideally in spring before peak cooling season. See our AC Maintenance page for a full checklist.

  • What temperature should I set my AC in summer?

    For energy savings, try 78°F when you’re home and higher when away. A smart thermostat can help manage this automatically.

  • Can you help with cooling in older homes or additions?

    Yes! Ductless mini-splits are great for spaces without ductwork or rooms with unique comfort needs.

  • What brands do you install or service?

    We work with all major brands and models. If you’re not sure what you have—or what you need—we can help you compare options.

  • Do you serve both homes and businesses?

    Absolutely. We offer cooling services for homes, office buildings, rental properties, and more. See our Who We Serve section for details.
