Claim This BusinessL&S Mechanical operates from a Richardson headquarters at 1101 E. Arapaho Road, serving residential clients across Dallas, Fort Worth, Austin, Houston, and San Antonio. With more than three decades of hands-on experience and a portfolio exceeding 100,000 completed service calls, this full-spectrum contractor employs licensed technicians across heating, cooling, plumbing, and electrical trades. The company holds multiple state licenses, including plumbing M-43951 for North Texas and HVAC TACLA134233E, and maintains a near-perfect 4.9-star average drawn from nearly 2,100 customer reviews.
What distinguishes L&S Mechanical from typical trade contractors is their integrated service model: a single phone call brings expertise in four distinct disciplines without coordinating separate vendors. Their technicians operate on flat-rate salaries rather than commission, removing financial incentive to oversell repairs or replacements. Recent expansion added dedicated plumbing capabilities through Chaparral Plumbing, strengthening their position as a single-source solution for homeowners facing simultaneous system failures.
Customer reviews highlight specific technicians who deliver exceptional care. Christopher Garrett earned praise for on-time toilet installation at a new-build home, with the reviewer noting his efficiency and refusal to leave until the problem was fully resolved. Another reviewer described electrician Joe arriving on New Year's Eve during a generator malfunction, tracing complex wiring to locate a tripped circuit board within minutes and saving the family's holiday. These named accounts represent patterns across feedback praising response time and diagnostic precision.
Technician-named reviews consistently award five stars, Christopher Garrett for plumbing precision, Joe for rapid generator troubleshooting during emergencies, Tim and Jeff for detailed HVAC explanations. Mixed-feedback reviews cite isolated cases of delayed follow-up on secondary requests, while positive feedback emphasizes transparent diagnostics over upselling.
