MJB Heating & Cooling

Founded in 1984, MJB Heating & Cooling has spent four decades building a trusted name in residential and commercial HVAC serving Derby, Wichita, and the surrounding Kansas communities. The family-owned operation holds a 4.8-star rating from 157 reviews, a record that reflects consistent delivery on promises made to homeowners and business owners alike. Their 24-hour, seven-day availability means a heating failure on Christmas morning or an AC collapse during a July heat wave gets the same rapid response. Located at 713 N Buckner St in Derby, the company dispatches technicians across a service area that spans more than 40 cities in the Wichita metro.

What distinguishes MJB from the field comes down to brand partnerships and service philosophy. As a Daikin dealer, they install systems backed by the Comfort Promise, a one-year guarantee that if any installed equipment fails to meet expectations, the company returns to resolve it at no additional cost. Their financing program offers 72 months of zero-interest payment plans, making new system installation accessible without upfront financial strain. Technicians receive specific training on the Daikin Difference, which emphasizes individual comfort control through zoning capability and energy-efficient design. The company also maintains a Friends & Family Maintenance Plan covering seasonal furnace and AC tune-ups, filter replacements, and priority service for breakdowns, essentially hedging against emergency failures.

Customer stories from reviews name specific technicians who earned their reputation. Tom Buck answered a Sunday emergency call, arriving within 30 minutes of the initial phone call to diagnose and repair a system that left a household with health vulnerabilities in the heat. For a commercial building owner, Dale and the team located a replacement 20-ton AC unit five weeks ahead of any competitor's promise, sourcing equipment during a supply shortage that left other contractors empty-handed. Multiple reviewers, Arli Lindskog, Jeff Schnell, and KJ Jones, specifically note that technicians do not push unnecessary purchases, instead explaining issues and presenting options. Sarah Elliott's review praises the owner and crew for being thoughtful, punctual, and attentive throughout the entire service process.
