Alaniz Mechanical Inc

Alaniz Mechanical Inc holds a perfect 5-star rating across 10 reviews, reflecting consistent homeowner satisfaction in San Francisco and throughout the Bay Area. License #1044935 authorizes this contractor to design, install, and service heating, ventilating, and air-conditioning systems for commercial, industrial, and residential clients. The company serves the full SF Bay Area alongside the Central Valley corridor spanning from Modesto to Visalia, positioning them as a regional mechanical contractor with broad geographic reach.

This contractor distinguishes itself through an unusually comprehensive license portfolio. Beyond standard air conditioning and heating work, Alaniz Mechanical holds licenses for low-temperature refrigeration, boilers, ventilating systems, and architectural sheet metal fabrication. Their engineering and construction divisions handle projects from initial design through final installation, while their service and repair team maintains existing systems. This vertical integration allows single-source responsibility for complex HVAC projects that many competitors must subcontract.

Reviewers consistently highlight specific technicians who resolved urgent problems. When a homeowner's furnace failed on Thanksgiving morning, Marcelo arrived within an hour, diagnosed a faulty sensor, and completed repairs in 30 minutes. Another reviewer praised Julian for rapidly replacing an A/C compressor. Jordan earned recognition for communicating every step of the repair process and solving a same-day unit problem. These accounts describe a team that prioritizes rapid response and thorough explanations even during emergency calls.
