Technicians arrive early, diagnose problems thoroughly, and explain options clearly. Named staff like Edwin, Zach, Eliot, and Alfredo handle AC repairs, installs, and maintenance with professionalism; customers report same-day fixes and pricing better than other quotes. The business earned a 4.9 rating across nearly 1900 reviews, with 94% five-star ratings.
Cobex delivers solid work backed by friendly, professional crews who clean as they go. Most jobs finish on schedule with attention to detail, though one reviewer reported shingles and glass entering through a skylight during removal.
Review evidence is limited for this business. GoNano states they offer nanotechnology roof treatments (claiming UL impact and fire certifications) at $5,000–$7,000, and operate in Sacramento; their website claims service since 1963. Direct customer feedback is not yet available.
Roofchecks earns strong praise for responsiveness, fair pricing, and thorough work. One reviewer experienced a leak recurring after two repairs, though the owner followed up to apologize.
