Advent Air Conditioning: Purpose-Built Climate Control for RVs
Advent Air is a dedicated RV climate control brand operating under the ASA Electronics family of brands, headquartered in Elkhart, Indiana — the heart of the RV industry. While ASA Electronics covers a broad range of mobile electronics, Advent Air has a singular focus: keeping RV occupants cool, comfortable, and in control of their environment no matter where the road leads.
Advent Air is engaged in the design, manufacturing, and marketing of climate control systems for mobile environments, including RVs, 5th wheels, and trailers. That narrow focus translates into deeply engineered products that address the specific challenges of mobile living — from road vibration and UV exposure to temperature extremes and moisture intrusion.
Engineered for the Rigors of the Road
What sets Advent Air apart is a commitment to real-world durability testing. Advent conducts strenuous tests under real-life conditions, which include vibration, humidity, UV exposure, water spray, and temperature fluctuations, ensuring its products will survive in the toughest mobile environments. This philosophy shows up in construction details that matter: units are built with a durable metal frame and advanced condensation management, providing efficient, quiet performance while maintaining a secure, weather-tight seal.
Advent Air's signature Flash Freeze technology, known for delivering direct downward cooling for faster comfort, remains a core feature of ducted systems. And the numbers back up the engineering: Advent Air maintains an industry-leading 0.7% warranty rate, supported by design choices such as a reinforced metal drip pan, which offers superior durability compared to plastic alternatives commonly used in the category.
A Complete RV Air Conditioning System
Advent Air's lineup is built around a complete system approach. The collection includes Advent Air rooftop AC units and replacement parts, covering popular models like the ACM150 (15,000 BTU) and ACM135 (13,500 BTU), along with ceiling assemblies, control kits, and service components. Available in 13,500 BTU and 15,000 BTU configurations, they fit standard 14" x 14" RV roof openings and are designed as direct replacements for many common units.
The system is also keeping pace with environmental standards. The EPA implemented a mandate that all rooftop air conditioners sold in the US must use R32 refrigerant, which has a lower impact on ozone depletion, and the new refrigerant has additional requirements for the components used in conjunction with the system. Advent Air's current lineup is fully compliant with these 2025 UL certification requirements.
For owners looking to explore the full range of Advent Air Conditioning products, the selection spans complete rooftop systems, ducted and non-ducted ceiling assemblies, digital thermostats, and service parts — everything needed to install, maintain, or upgrade an RV's climate control system.
Redesigned for the Modern RV Owner
ASA Electronics announced the launch of a fully redesigned Advent Air RV air conditioning system, marking the brand's first complete aesthetic and functional overhaul in nearly a decade. The new lineup delivers modern design, trusted performance, and enhanced user control, while reinforcing ASA's commitment to authentic engineering and long-term durability in an increasingly competitive RV climate-control market.
