“Steve promptly assisted me this past summer when my central air unit quit during a heat spell and while I was studying for a certification. He was able to send a technician (Dane) out the same day the issue occurred and had a new AC unit installed within a few days. I also experienced an issue with my water heater recently and once again, Steve was able to send Dane out to fix the problem the same day I called. The work performed was reasonably priced and was of sound quality.”
“I own and operate a Dairy Queen. One of my coolers went down. After contacting the after-hours line, Matt and another technician arrived. They diagnosed the problem, gave me options and ultimately fixed my cooler and I’m back up and running. You can’t ask for more professional, prompt and all-around great service. I’ve used Karolyi’s for the past 6 years and have never been let down.”
“Our furnace went out late on a Saturday night. We called Sunday morning and had two technicians out right after breakfast. Thankfully, it was a quick fix, but they stayed on site for a while to make sure the furnace ran (and stayed running!). Thank you so much!”
