Our Comprehensive Services
HVAC Repair and Replacement
Whether it’s a failing furnace or an aging AC, Big Wave handles everything from emergency repairs to full system replacements. With upfront pricing, a No Hidden Cost Guarantee, and warranties up to a lifetime on select parts, you’ll get lasting comfort without surprise expenses.
Told You Need a New AC? Rejuvenate It Instead.
Another company telling you it’s time for a $10,000+ replacement? Get a free second opinion from Big Wave first. Many systems we inspect have years of life left — they just need our Factory Rejuvenation service to run like new again.
Air Duct & Dryer Vent Cleaning
Dust, allergens, and hidden buildup in your ducts reduce air quality and strain your system. Our duct cleanings restore airflow and efficiency, while dryer vent cleanings cut fire risks and improve safety. Many homeowners bundle services with seasonal maintenance for maximum protection.
