Donovan & Jorgenson - Western Office

Donovan & Jorgenson maintains a 4.9-star average across 36 customer reviews in Mukwonago, Wisconsin. The contractor operates Monday through Friday from 7:30 AM to 4 PM, providing furnace, air conditioner, and garage heater services to residential clients in the greater Mukwonago area. This Western Office location serves the eastern Wisconsin market for a company whose technicians specialize in annual maintenance tune-ups, system installations, and diagnostic repairs.

Without access to the company's current website or service documentation, the specific brand partnerships and specialty certifications cannot be verified for this listing. The contractor's online presence appears limited or currently unavailable, which prevents confirmation of dealer certifications, equipment guarantees, or rebate program eligibility.

Multiple reviewers specifically commend a technician named Tony for his maintenance work, with one client noting they request him by name for annual furnace and AC tune-ups. Another reviewer describes a multi-day installation project involving a furnace, air conditioner, garage heater, and new zoning system, during which the crew communicated evening updates and walked the homeowner through the completed work. A third client mentions the team arrived on time, cleaned thoroughly after installing both heating and cooling equipment, and explained system operation before departing.
