About Firefly Comfort Systems
Firefly Comfort Systems serves Austin homeowners from its local base at (512) 994-5545. The contractor holds a 4.9-star average across 53 verified client reviews, reflecting consistent service quality in the capital city. This rating places the company among the highly regarded residential HVAC specialists operating in the Austin metro area.
Both reviewers awarded five stars and described specific positive outcomes. Joe Labriola noted the contractor resolved a puzzling heat pump issue during the record cold of 2021 through a phone diagnostic, then installed a new air exchanger within two days. Catie Bishop highlighted an honest quote and timely completion during a home sale, with the technician walking the buyers agent through the repairs.
What Customers Say
Both five-star reviewers named Aaron as the technician who handled their calls. One described a same-day phone diagnostic during the 2021 Austin freeze that correctly identified the problem; the other noted squeezing in for an annual check and completing replacement work ahead of a home sale.
