Claim This BusinessAustin's Green Air & Heating has been keeping Central Texas homes comfortable for over a decade. Based in Austin, this licensed HVAC contractor holds a 4.8-star rating across 108 customer reviews, reflecting consistent service quality in a region where summer temperatures routinely exceed 100 degrees. The company serves residential and commercial properties across a dozen cities, including Austin, Round Rock, Georgetown, Cedar Park, and New Braunfels. Their team operates Monday through Friday from 8 AM to 6 PM, with 24/7 emergency availability for system failures that cannot wait until morning.
What distinguishes this contractor is their specialization in Mitsubishi Mini-Split systems, a ductless technology increasingly popular in Austin's older homes and new construction alike. They also handle complete indoor air quality solutions, including humidifiers and dehumidifiers designed for the region's humid summers and occasional dry winter months. For new builds and remodels, the company designs and installs custom ductwork systems from scratch. Service packages include preventative maintenance agreements aimed at extending equipment lifespan, a practical approach for homeowners seeking to avoid mid-summer breakdowns.
Owner Casimir leads a team that reviewers consistently describe as honest, knowledgeable, and reachable. Technician Sonny earned praise for arriving the day after a Sunday call and explaining system maintenance in plain language. Another reviewer, Travis, resolved a furnace control board issue with prompt, efficient service. A third customer noted that Casimir waived his fee when a repair did not fully resolve the problem, an uncommon gesture that earned trust. The company handles both routine maintenance and full system replacements, including equipment from American Standard.
108 reviewers award an average 4.8 stars, with repeated mentions of Same-Day arrival during heat waves, Honest diagnosis without upselling, and 24/7 emergency responsiveness. Technicians Casimir, Sonny, and Travis receive individual name recognition across multiple five-star reviews.
