About First Co.
First Co. operates as a Dallas-based air conditioning contractor with 139 client reviews yielding a 3.4-star average. The company maintains standard weekday availability from 8 AM to 5 PM, serving residential and light commercial customers throughout the Dallas metro area. Established as a regional HVAC provider, First Co. handles installation, maintenance, and repair services for cooling systems in homes and small commercial properties. The company operates out of its Dallas office facility and responds to service calls within the broader metropolitan area.
Publicly available information about First Co.'s specific brand partnerships, certifications, or specialized services remains limited. The company does not appear to list branded partnerships on accessible platforms, and detailed service offerings such as indoor air quality solutions, equipment warranties beyond standard manufacturer coverage, or specialized repair guarantees are not readily documented in current public materials. Prospective clients may benefit from direct inquiry regarding specific equipment brands, service agreements, or workmanship assurances.
Customer feedback reveals concerning patterns worth noting. Multiple reviewers document interactions with staff members identified as Bill and Brandon, citing disagreements over supervisor identification during customer service calls. Reviewers also report equipment failures occurring within two to three years of installation, including fan coil leaks and compressor failures, with reported resolution timelines extending from several weeks to over a month during peak summer months. One reviewer notes a three-and-a-half-year-old unit required multiple repair attempts before eventual replacement.
