A Tradition of Excellence: Why Racine Trusts Keystone
At Keystone Heating & AC, we believe that premier service isn’t just about fixing a furnace or installing a new air conditioner; it’s about the peace of mind that comes from a century of commitment to our neighbors. Since 1918, we have been a staple of the Racine and Kenosha communities, and today, that commitment to quality is stronger than ever!
Voted "Best of Racine" Two Years Running
We are incredibly honored to announce that Keystone Heating & AC has been voted Best of Racine for HVAC service for the past two years! This award is particularly meaningful because it is decided by you, the homeowners and business owners we serve every day.
Being recognized as the premier HVAC provider in the area is a testament to our team’s hard work, technical expertise, and our "customer-first" philosophy. Whether it's a sub-zero January night or a humid July afternoon, our goal remains the same: providing reliable, honest work that our community can depend on.
What Our Customers Are Saying
While awards are a great honor, the true measure of our success is the feedback we receive from our customers in Racine, Union Grove, and Kenosha. With a near-perfect 4.9-star rating across our Google profiles, we are proud to share the experiences that define the "Keystone Difference":
Prompt & Reliable Emergency Care: Customers frequently highlight our 24/7 responsiveness, with one recent reviewer noting that after calling after midnight, a technician was at their door "right away" with the necessary parts to fix their system on the spot!
Professionalism You Can Trust: Our technicians are consistently praised for their courtesy and cleanliness. From putting down tarps to protect your floors to taking the time to explain every step of a repair, we treat your home with the same respect we would our own.
Value and Integrity: Many of our long-term customers, some of whom have been with us for over 40 years, point to our Annual Service Agreement as an "outstanding value" that provides year-round comfort without the stress of unexpected breakdowns.
A Century of Service, A Future of Comfort
Under the leadership of Racine native Gene Townsend, Keystone continues to blend time-tested expertise with the latest in energy-efficient HVAC technology. We aren't just your contractors; we are your partners in maintaining a safe, comfortable, and efficient home.
