About Nix Plumbing Heating & AC
Nix Plumbing Heating & AC operates as an air conditioning contractor serving Brea, California. The business maintains standard weekday hours from 7 AM to 5 PM, Monday through Friday, and can be reached directly at (714) 527-1311. With a rating of 4.2 stars drawn from five customer reviews, the contractor has built a local reputation among Brea homeowners for both diagnostic accuracy and transparent pricing on repair and replacement work.
This contractor distinguishes itself through a diagnostic-first approach that reviewers describe as saving them thousands of dollars. Rather than recommending full system replacements, the team assesses existing equipment to determine whether targeted repairs resolve the issue. One reviewer documented how the technician correctly identified a failing motor requiring replacement, avoiding a $5,000 new unit purchase that other area contractors had suggested.
Customer reviews name Dale as a technician who provided straightforward explanations and punctual service during a forced air system and ducting replacement project. Another reviewer documented same-day arrival during an urgent call and credited the team's experience in accurately diagnosing the issue. However, one review documents serious concerns about equipment transparency and electrical code compliance on a prior installation, which the reviewer indicates required subsequent correction by another contractor.
What Customers Say
Two of three reviewers praise the diagnostic accuracy and cost savings, with one documenting a $4,500 difference between Nix's $500 motor repair and competitors' $5,000 replacement quotes. The negative review cites equipment misrepresentation and electrical code violations that required remediation.
