L&S Mechanical

L&S Mechanical is a full-service home systems contractor based in Melissa, Texas, with a home office in Richardson. Founded more than 30 years ago, the company has completed installations and service calls for over 100,000 Texas homes across five major metro areas: Austin, Dallas, Fort Worth, Houston, and San Antonio. The company holds licenses spanning HVAC (TACLA134233E), electrical (TECL29708), and plumbing (M-43951 for North Texas, M-43337 for Austin, Houston, and San Antonio). With 391 reviews averaging a 4.9-star rating, L&S offers heating, air conditioning, plumbing, and electrical work through a single point of contact, a model that appeals to homeowners managing multiple trade needs.

What distinguishes L&S Mechanical is their technician compensation structure: service providers are salaried rather than commissioned, which the company states eliminates pressure to recommend unnecessary repairs. Every field technician undergoes background verification, drug screening, and driving record checks before entering customer homes. The company recently expanded capabilities by acquiring Chaparral Plumbing, strengthening their residential service portfolio. Builder services also appear prominently on their website, suggesting established relationships with construction professionals for new-build installations.

Customer reviews frequently mention specific technicians resolving acute problems. Ray repaired a slow leak in a new home by identifying a faulty seal, and a reviewer thanked Ray for adjusting a mixing valve in a master bath that was causing temperature inconsistencies. Gustavo earned recognition for explaining repair options clearly, arriving on time, and completing work efficiently after a freeze cracked an outdoor spigot. The lone 2-star review describes a shower installation that required warranty callbacks and eventual third-party repair, indicating that while most customers report positive experiences, quality control varies by project.
