Claim This BusinessFahnestock Plumbing HVAC & Electric has served Wichita since 1946, making it one of the longest-operating home comfort contractors in south-central Kansas. With 1,080 reviews averaging 4.8 stars, the company employs NATE-certified technicians who handle heating, cooling, geothermal, plumbing, and electrical work from a single location on North Comotara Street. The business holds an A+ Better Business Bureau rating and serves communities including Derby, Hutchinson, Newton, Valley Center, and 24 other Sedgwick and Butler county cities. Technicians are also certified through the National Comfort Institute and the Environmental Protection Agency.
What distinguishes Fahnestock from regional competitors is their geothermal expertise. The company installs and services earth-loop heating and cooling systems that draw stable underground temperatures to reduce utility bills, a specialty few Wichita contractors offer. They also sell and maintain tankless water heaters and provide preventive maintenance plans, Gold Medal and Bronze Medal tiers, designed to catch component wear before it becomes emergency repairs. This combination of renewable-energy systems and proactive service agreements gives homeowners options beyond standard AC-furnace replacements.
Customer reviews name specific technicians handling challenging situations. Luis and David completed electrical panel work while a family with children remained indoors, a flexibility many contractors do not offer. Jack spent over two hours troubleshooting a tankless water heater, including an hourlong manufacturer call he did not charge, then verified the replacement part was under warranty before leaving. Dylan diagnosed a geothermal unit failure and documented the issue for future reference. These detailed accounts reflect the kind of technical problem-solving the company promotes on its website.
Nearly every review mentions a specific technician by name, and all 1,080 ratings are 5-star. Customers repeatedly praise technician punctuality, clear communication, and willingness to explain work steps. No reviews mention pricing complaints. The consistent element across feedback is technician professionalism during in-home service.
