Hamil, Harrison & Co. LLC

Hamil, Harrison & Co. LLC has anchored itself in Ennis since 1955, making it one of the oldest still-operating HVAC contractors in Ellis and Navarro Counties. Holding state license TACLA35040CTACLB56943E, the company boasts a 4.8-star rating drawn from 33 owner-submitted reviews, a volume that signals sustained service quality rather than flash-in-the-pan excellence. James Davis and Scott Payne now lead operations, supported by a team of licensed, insured technicians who maintain credentials through ongoing manufacturer training programs. The firm handles full-scope residential and commercial heating and cooling work, operating weekdays from 7:30 AM to 4:30 PM.

Unlike many regional contractors who chase any equipment brand, Hamil, Harrison & Co. holds the Trane Comfort Specialist designation, a credential awarded only to firms meeting Trane's exacting benchmarks for technical capability and customer satisfaction. This distinction means the team installs and services Trane's highest-efficiency systems, including models eligible for manufacturer rebates. Their licensure through the Texas Air Conditioning Contractors Association tracks their standing, while bi-annual preventative maintenance programs help customers sidestep emergency breakdowns before peak summer heat arrives.

Reviewers repeatedly name Victor Garcia, describing him arriving within 30 minutes of an early-morning call for a heating failure, diagnosing the issue while explaining the fix to a curious homeowner, and completing repairs that had other companies stumped. Another reviewer documents the team arriving within one hour on a same-day call during sweltering weather, getting her AC running before her house overheated. Those rapid-response scenarios occur alongside mentions of the team's upfront pricing and refusal to recommend unnecessary work.
