David and his crew are to be commended. We originally hiring another company to complete the home performance package through the City of Austin - it took them almost 6 months of working at least 2-3x a month and could never get our home below 40% leakage. David and his crew came in and fixed everything in 1 day and got us below 8% leakage - AMAZING.
David knows the business and has good relationships with the folks at Austin Energy. I highly recommend them and will use them for any a/c needs in the future!
