Delong Air Inc has been serving Springfield, Ohio area homeowners since its founding, providing heating and cooling services across Clark County and surrounding communities. The company holds proper licensing for HVAC work in Ohio and maintains an A+ rating with the Better Business Bureau, supported by 238 client reviews that average 4.7 stars. Their service fleet responds to calls Monday through Friday from their Springfield base, handling everything from emergency furnace repairs to new system installations for residential clients.
Kevin Vest, one of Delong Air's senior technicians, has earned particular praise from customers for his diagnostic approach and transparent cost explanations. Several reviewers note he takes time to walk homeowners through the repair process, allowing them to observe work and ask questions. The company operates a homeowner maintenance club program that offers customers priority scheduling and discounted service visits, a benefit multiple reviewers mentioned after experiencing same-day response during heating emergencies.
What Customers Say
5 of 6 posted reviews award 5 stars, with all positive assessments specifically naming technician Kevin Vest for his thorough explanations and efficient repairs. The single 1-star review concerns a dispute over warranty work rather than service quality.
