NexGen HVAC & Plumbing

NexGen HVAC & Plumbing operates as a licensed HVAC contractor and plumber serving Ventura County and surrounding Southern California communities, including Simi Valley, Thousand Oaks, Moorpark, and Newbury Park. The company maintains a 4.8-star rating across 1,538 client reviews, demonstrating sustained service quality over years of operation. This contractor offers around-the-clock availability, which proves essential during temperature extremes when cooling or heating systems fail unexpectedly. Their service repertoire spans residential air conditioning, heating systems, indoor air quality solutions, comprehensive plumbing, drainage, and even electrical upgrades including EV charger installations and whole-home surge protection.

What distinguishes this contractor is the depth of their indoor air quality expertise. Beyond standard HVAC service, they install REME HALO whole-home air purifiers, perform professional air duct sealing to prevent conditioned air loss, offer duct cleaning, and provide home insulation services that improve overall system efficiency. Their plumbing division handles complex work including slab leak detection with specialized equipment, trenchless sewer line repair to avoid landscape disruption, tankless water heater installation, and gas line services requiring certified expertise. They also market financing options, making major system replacements more accessible for homeowners facing unexpected equipment failures.

Reviewers consistently highlight specific technicians who delivered exceptional service. Lazaro, referenced by name in a 5-star review, thoroughly explained a thermostat replacement scenario, performed condenser cleaning, patched air leaks, and installed an ionizer while detailing each step for the homeowner. A reviewer named Brian Woodward recounts purchasing a new HVAC system from NexGen five years ago and receiving ongoing service, though expressing frustration with a recent $10,000+ repair estimate for the aging system, an honest portrayal of the costs associated with maintaining older equipment.
