Customer Praise for Going The Extra Mile

You won’t find these reviews on Google—but they’re every bit as real.

At Keystone Heating & AC Co. Inc., we believe that top-tier service starts with respect, reliability, and hard work—qualities our team brings into every home we enter. While these testimonials didn’t come through Google, they were submitted directly to us through our website’s contact form by real customers who wanted to share their experiences. We’re proud to highlight their words here.

Recently, two of our local customers shared their appreciation for our technician Greg Williams. We couldn’t be prouder to share what they had to say.

“Thorough and Respectful—From Start to Finish”

“I just need to say—if most employees are like Greg Williams, who was assigned the maintenance on my air conditioner, you’re in good hands. He was so thorough and respectful the entire time spent here. Please relay our thanks and gratitude. Keep up the great job!”

— Paulette R., Mt. Pleasant, WI

Paulette’s kind words remind us that attention to detail and a respectful approach aren’t extras—they’re essentials. We’re grateful to her for recognizing the level of care our team strives for.

“Prompt, Professional—and Unfazed by Mice!”

“I'd like to give a HUGE shout-out to your employee Greg W. He worked on my friend’s air conditioner while I was house-sitting. Greg was prompt and professional—even had to battle mice just to get started! I highly recommend Keystone Heating and AC for all of your heating or AC problems!”

— Anne M., Racine, WI

Sometimes the job throws us curveballs—like unexpected critters—but that doesn’t stop our technicians from getting the job done right. Anne’s experience shows just how committed our team is to doing the work with professionalism, no matter the challenge.

We’re proud to serve our local communities with the same level of care, precision, and perseverance every single day. Whether it’s your home or a friend’s, we treat every service call like it matters—because it does.
