Frequently Asked Questions About Air Conditioning Services


  • How Often Should I Schedule AC Maintenance?

    We recommend once per year, ideally in the spring before summer temperatures rise. This ensures your system is running efficiently and reduces the risk of mid-season breakdowns.

  • Can You Install a New Air Conditioner in an Older Home?

    Absolutely. We specialize in both traditional and ductless systems for older homes without existing ductwork. We’ll assess your space and recommend the best option.

  • How Do I Know if My AC Needs Repair or Replacement?

    If your system is over 10–15 years old, frequently needs repairs, or is driving up energy bills, it may be more cost-effective to replace it. We’ll help you weigh the pros and cons before making a decision.

  • Do You Offer Emergency AC Repair?

    Yes! We offer 24/7 emergency service for urgent cooling system issues. Whether it’s a weekend or a holiday, our technicians are available when you need them most.

  • Are Your HVAC Installations Covered by Warranty?

    Yes. Most systems come with manufacturer warranties, and we back our labor with a satisfaction guarantee. We’ll walk you through all warranty coverage details during installation.
