About Corressell Heating & Air Conditioning
Corressell Heating & Air Conditioning has served the Mt Vernon, Indiana community for over two decades as a family-owned HVAC contractor. With an exceptional 4.8-star rating drawn from 39 verified customer reviews, the company has built a reputation for reliable heating and cooling solutions throughout Posey County and surrounding areas. Their team of licensed technicians operates Monday through Friday from 8 AM to 4:30 PM, providing both residential and light commercial service calls to homeowners in Mt Vernon and neighboring communities like New Harmony and Evansville.
What distinguishes Corressell from neighboring contractors is their commitment to transparent pricing and thorough craftsmanship. Several reviewers specifically mention the team's reasonableness compared to other area companies, with technician Dan providing detailed quotes for mini-split system installations. The company handles everything from emergency furnace repairs to planned system upgrades, and they back their work with professional cleanup practices that customers consistently praise. Their office staff maintains clear communication, ensuring scheduling works around homeowner availability.
Customer stories from reviews reveal the team's dedication under pressure. When Charlie McMahon's AC failed during the hottest week of the year, technician Chris dispatched someone within two hours, resolving the 87-degree office crisis. For Jerome M's decades-old furnace, technicians Mike and his partner completed a demanding two-day repair job that other contractors feared was impossible. Current s like Ray K praise technician Gabe for thorough seasonal maintenance that maximizes system longevity, while Micky Hammers recounts Dan's knowledgeable estimate for mini-split installations completed with precision.
What Customers Say
Thirty-nine reviewers collectively award Corressell a 4.8-star rating, with every customer awarding 5 stars. Three clients mention same-day or two-hour emergency response during extreme heat, while four reviewers specifically praise technicians by name: Mike, Dan, Gabe, and Chris. The only recurring theme across negative-adjacent comments involves pricing, though these reviewers still give 5 stars, suggesting the team's diagnostic skill justifies costs.
