Arnold Moos Plumbing Heating & AC

Arnold Moos Plumbing Heating & AC has served San Antonio since 1971, delivering more than five decades of continuous HVAC and plumbing service from a single location at 11326 IH-35 North. The Moos family operation holds current licensing and maintains an A rating with the local BBB chapter. Homeowners in neighborhoods along the IH-35 corridor, from North Central San Antonio through Castle Hills to Live Oak, regularly call on this contractor for both scheduled maintenance and urgent repairs. The company maintains a 4.8-star average across 45 verified Google reviews, with many reviewers noting they have been clients for a decade or longer.

What distinguishes Arnold Moos from newer competitors is their depth of equipment expertise. As a Trane dealer, they install and service heat pump systems designed for the South Texas climate, including variable-speed models that handle humidity control more efficiently than standard single-stage units. The company offers preventive maintenance agreements that include biannual tune-ups, filter changes, and priority scheduling during summer heat waves when same-day service fills quickly. Their website promotes financing options for major equipment replacements, and they maintain a Parts and Labor warranty on installed systems.

The reviews reveal specific technicians who have earned long-term client loyalty. James King has relied on Mr. Jesus Madrigal for twelve years, praising his punctuality and systematic maintenance approach that has extended the life of his home systems. Sue Stewart describes how Jessie monitored her home temperature hourly during an AC failure to ensure her family stayed comfortable while the system was repaired. Carla Jordan called at 7 AM describing a blocked kitchen drain, and Kelly dispatched plumber Jim who arrived within 30 minutes. These interactions illustrate why reviewers describe the team as professional and knowledgeable.
