Who you're calling

Mike Caldwell
Owner & Lead Technician ยท Louisville, KY

I've been working on heating and cooling systems in Louisville for 12 years. Started out with a big company, spent six years learning everything I could โ€” then went independent in 2018 because I was tired of upselling customers on things they didn't need.

When you call TrueTemp, you're calling me. I'm the one who shows up, does the work, and stands behind it. No crews, no middlemen. If something's not right, you tell me and I fix it โ€” that's the whole deal.

Why TrueTemp

The Guy You Actually
Want Showing Up

Here's what makes working with an independent tech different โ€” and better.

โ˜…โ˜…โ˜…โ˜…โ˜…

"Called at 8am on a Saturday, he was here by 10. Diagnosed the problem in 20 minutes, gave me an honest quote, and had the AC running before noon. No upsell, no nonsense."

โ€” Marcus T., Highlands
โ˜…โ˜…โ˜…โ˜…โ˜…

"After getting a $4,200 quote from a big company to replace my whole unit, TrueTemp found a bad capacitor and fixed it for $180. I trust this guy with my house."

โ€” Jennifer L., St. Matthews
โ˜…โ˜…โ˜…โ˜…โ˜…

"He actually answered his phone. Came out same day. Explained everything clearly. This is how all service businesses should operate."

โ€” Dave R., Jeffersontown
