A+ Derr Heating & Cooling

A+Derr Heating & Cooling has earned a reputation as Southern Indiana's most responsive residential climate specialist, maintaining 24/7 availability while serving Newburgh and surrounding communities including Evansville, Boonville, and Vincennes. Founded in the early 2000s, this family-oriented contractor holds current state licensing and has accumulated 5,343 verified reviews averaging 4.9 stars, a volume that reflects both consistency and community trust. The company handles furnace, air conditioning, and mini-split installations for homeowners ranging from first-time buyers to long-term residents replacing aging systems.

What distinguishes A+Derr from regional competitors is their commitment to single-visit installations even for complex multi-unit projects. Recent reviews document same-day setups combining furnace, AC, mini-split zones, and tankless water heaters, work that typically requires multiple contractor visits elsewhere. Their technicians arrive with detailed checklists and document installations via video walkthroughs, giving homeowners visual records of completed work. The company partners with major manufacturers including Lennox for equipment sourcing and offers scheduled maintenance programs designed to extend system lifespan through seasonal filter changes and coil cleaning.

Customer stories from 2025 highlight specific technician experiences. Kevin resolved a no-heat emergency by arriving before 11am after an early morning call, diagnosing a failed igniter and explaining maintenance options. Jacob completed a full system installation in one working day while adhering to specification details. For Shirley and Rick Willis in Madisonville, Kentucky, technicians Ian Hartz and Addison B installed a new Lennox system in 25-degree outdoor temperatures, completing the replacement of a 1992 York unit with meticulous step-by-step coordination.
