M&S Mechanical — a Texas HVAC company built on straight answers.
A family-owned HVAC company serving Houston and Dallas with AC repair, installation, maintenance, and heating.



M&S Mechanical was built around one idea: HVAC service should feel clear from the first call to the final walkthrough. Every job starts with a real conversation about what your system is doing and what the right next step is — not a script.
A Family-Owned Business Built Around Accountability
M&S Mechanical is a family-owned and family-operated company that has been in business for 53 years. Family ownership brings personal responsibility to the way the business operates. Decisions are made with attention to the customer experience, the quality of the work, and the long-term usefulness of the recommended solution.
Our service standards are simple: listen carefully, communicate in plain language, respect the property, and help customers understand what their system needs. We believe an HVAC contractor should do more than identify a problem — the service experience should also give the customer a clear explanation of the issue, the available path forward, and the next step for maintaining a comfortable space.
Local Markets We Serve
M&S Mechanical serves two important Texas markets: Houston and Dallas. Our services include AC repair and installation, seasonal maintenance, heating, indoor air quality, and ductless HVAC solutions.
