Wil (William Arthur) Fonder
Owner & Master Mechanical Contractor • Prior Lake Native
In an era where local heating and air conditioning companies are rapidly bought up by national private equity firms with sales quotas and commissioned technicians, Performance Mechanical remains fiercely independent and owner-operated.
Wil Fonder completed rigorous formal technical education at the renowned Dunwoody College of Technology, earning his Associate of Applied Science (AAS) in HVAC/R System Servicing. He advanced his trade mastery through the prestigious St. Paul Pipefitters Apprenticeship Program (Local 455), working on complex commercial piping, industrial refrigeration, and high-pressure steam and hydronic heating systems.
Today, Wil brings that rigorous commercial-grade precision directly to residential basements and commercial kitchens across Shakopee, Prior Lake, Savage, Chaska, and Scott County. When you call our office, Wil answers the phone. When a technician arrives at your home, you are working directly with the master contractor whose name and reputation are on the line.

We treat your home like family. No pushy sales, no scare tactics, and no unnecessary replacements.

Real Words From Twin Cities Homeowners
Our reputation is built on one honest install and repair at a time. Here is what real customers say about working directly with Wil Fonder.
“Replaced Furnace & Took Care of Rebates”
Excellent install, came prepared for everything, was friendly to the cat who wouldn’t leave him alone. Took care of rebate and registration paperwork so I wouldn’t have to. Only replaced the furnace - didn’t try to upsell me on components that were still functional.

“Thank you Robert for the great review! Thank you for allowing our company to take care of your mechanical needs!”
“Diagnosed Ongoing Furnace Shutdown Within Minutes”
Experienced ongoing furnace issues and others tried, but could not properly diagnose why it continued shutting down. One of my sons, an experienced Pipefitter, referred me to Will Fonder based on knowing and working with him. Thank God! Will was able to diagnose and fix the issues within minutes. He holds expert level knowledge, patiently answered my many questions, and is simply an exceptional person - all of these qualities are very rare today. HIGHLY RECOMMEND!

“Picked Up Water Heater on the Way & Restored Hot Water”
Wil is the best! We have used him twice now. This last time our water heater went out and he picked up one on his way to replace ours, he answered all my questions prior to coming as far as what he advised we replace the old with. He arrived right when he said he would, got everything replaced and everything was clean and we had hot water in no time. Best guy in the Twin Cities!
