With a rating of 4.6 stars across 18 customer reviews, the company has established a local presence delivering heating and cooling solutions to homeowners in the region.

Nate, the technician referenced in multiple positive reviews, demonstrates diagnostic skill that separates this contractor from standard service calls. One reviewer recounts how Nate identified a capacitor issue from a phone description alone, arriving with the correct part and resolving the problem the same day at a lower cost than anticipated. Another scenario involved a frozen coil complaint where the technician persisted through a two-hour investigation to discover the root cause: an improperly matched condenser and furnace pairing, which he corrected without charging for the return visit. This level of troubleshooting thoroughness distinguishes the service from quick-fix alternatives.

Customer feedback reveals service limitations worth noting. Negative reviews cite communication gaps, including a full voicemail box that prevented callback attempts and gaps exceeding a week between inquiry and response. Additionally, the contractor maintains a preference for servicing equipment they originally installed rather than systems purchased through alternative channels. These patterns suggest clients benefit most from engaging Hernke's for ongoing maintenance of their installed systems rather than seeking unrelated repair work.
