Claim This BusinessSustr's Air Conditioning Contractor has served Schulenburg and the surrounding Fayette County region for over 15 years as a family-owned and operated HVAC business. Led by Ben Sustr, the company holds a 4.8-star rating across 19 verified customer reviews, reflecting consistent quality in both residential and light commercial work. The contractor serves homeowners in Schulenburg, Dubina, and nearby communities, handling equipment replacements, system repairs, and preventive maintenance for all major brands.
This contractor holds Mitsubishi Diamond Contractor certification, one of only a handful in the region, specializing in mini-split heat pump systems for barndominiums, cabins, and custom off-grid installs. Their service menu extends to commercial HVAC, hydrokleen coil cleaning, and full system replacements. Unlike larger metro-area companies that treat rural customers as afterthoughts, Sustr's dispatches technicians directly from their Schulenburg base, reducing response times for emergency calls during South Central Texas heat waves.
Customer reviews repeatedly name Ben Sustr arriving same-day during heat emergencies. One reviewer called after a mini-split failure at a barndominium near La Grange; Ben diagnosed a control board failure, discovered varmint-caused wiring damage during the repair, and restored the entire system. Another reviewer requested help for an elderly family member; Ben provided a fair quote, treated the customer with respect, and completed the installation promptly. Several reviewers mention using Sustr for multiple properties, a cabin, a second home, demonstrating long-term trust in the company's workmanship.
All 19 reviews award 5 stars, with 6 specifically praising Ben Sustr by name. Reviewers highlight mini-split expertise, fair pricing, and fast same-day service during heat emergencies. Customers in rural properties like barndominiums and cabins cite Sustr's as their go-to contractor for multi-property installations.
