About us

36 years. Still family.

Thermal Services is a small, family-owned heating and air company based in Rock Hill. Big enough to have a crew and handle full system replacements; small enough that you know who's coming to your house.

Thermal Services, Inc. has served homeowners in the Carolinas since 1990. What started as a family business in the greater Charlotte region is still exactly that, now based in Rock Hill and serving Rock Hill, Fort Mill, Tega Cay, Indian Land and the communities around them.

Our mission, in the words we've used for years: "Our mission is to serve our clients with knowledge, trustworthy advice, and compassion! We treat every client like family!"

We do residential heating and air conditioning: repairs, maintenance, and system replacements, for homeowners and for landlords who own more than one property. We're not a call center. When you call, you talk to us.

What customers say about us

We'd rather you hear it from them. Across Google, Facebook and Nextdoor, the same themes come up again and again:

  • Honest. The word that comes up most. Reviewers say Josh tells them what's actually wrong and never pushes services they don't need.
  • Fair prices. Customers describe the pricing as fair and competitive, from routine service calls to full system replacements.
  • Shows up. One newer Rock Hill customer wrote about Josh coming out after hours during a heat wave.
  • Explains things. Reviewers mention patient explanations, advice for their other properties, and leaving work areas neater than they found them.
  • Like family. Customers who have used Thermal Services for years describe a family business they trust with their parents' homes and their own.

The people

Who you'll talk to

Josh Seger, Owner / Operator at Thermal Services

Josh Seger

Owner / Operator

Josh runs Thermal Services today and is the name neighbors pass along on Nextdoor: "ask for Josh." He holds associate degrees in HVAC and in Construction Management, and he's the one who picks up the phone.

Tim, Crew Lead at Thermal Services

Tim

Crew Lead

Tim has been part of Thermal Services for years. Reviews going back to 2017 thank "Tim and his crew" and "Tim and Josh" by name for honest, hardworking, careful work, and for going beyond the repair to clean and check everything else.

And the crew

Thermal Services has always been more than one person. It's a small team that takes pride in clean, careful work, big enough to handle full system replacements and small enough that you know who's coming to your house.

How we work

  • Tell the truth

    If it's a $20 part, we say so. If a system is done, we say that too, and show you why.

  • Price it fairly

    "When the time comes for you to replace your unit, we guarantee to provide you with a fair and competitive price."

  • Treat you like family

    The way we'd want someone to treat our parents' home. One longtime customer first called us for her parents.

  • Work as unto the Lord

    We're a faith-based company. Doing the job right when nobody's checking is part of that.
