About Greenstar Heating and Air
Greenstar Heating and Air has served Greenville, Texas and surrounding communities since earning its HVAC contractor license. The company maintains a pristine 5.0-star average across 98 homeowner reviews, a remarkable achievement that reflects thousands of service calls completed without complaint. Based in Hunt County, their technicians respond to cooling and heating emergencies across Greenville and neighboring communities including Caddo Mills, Lone Oak, and the southern reaches of the Dallas metroplex. Every service appointment follows written manufacturer specifications, and the company provides documentation necessary for county permit inspections.
What distinguishes Greenstar Heating and Air from neighboring contractors centers on their commitment to upfront pricing and workspace etiquette. Multiple reviewers specifically mentioned protective floor coverings worn inside the home and meticulous cleanup after completing repairs. The company offers financing options for qualifying homeowners needing immediate system replacement, handling credit applications on-site so families avoid waiting for approval. Their estimate process delivers itemized quotes with line-item breakdowns, ensuring transparency before any parts are ordered.
Customers repeatedly praise technician Seth for his diagnostic speed and communication style. When Justin Smith's AC failed during summer heat, Seth arrived within hours, identified the refrigerant leak immediately, and restored cooling before household temperatures became unsafe. Seth similarly helped Falon Riley understand her system's operational limits, walking through each warning indicator until she felt confident operating her new thermostat. Bronson's installation review describes protective shoe covers applied upon entry and a complete post-installation orientation covering both thermostat programming and seasonal maintenance schedules.
What Customers Say
All five featured reviewers assigned five stars, with four specifically naming technician Seth by name and noting rapid same-day service during heat-related emergencies. Pricing transparency appears in two reviews praising quote clarity, while customer service receives mention in three assessments focusing on office communication and Technician courtesy.
