Our Simple, No-Stress Repair Process
Your AC isn’t keeping up, and you need it fixed.
What you don’t need is a sales pitch about replacing the whole system.
Carolina Comfort sends a repair technician to diagnose the problem, explain what’s happening, and fix it.
That’s it.
- Same-Day AC Repair
Call by noon and a technician can be at your door today, not next week. - $99 Diagnostic, No Surprises
We find the problem, explain what’s wrong, and quote the repair before touching anything. - 30-Day Repair Warranty We stand behind every repair for 30 days. If the part we installed or the work we performed isn’t holding up, we come back at no cost.
Our Simple, No-Stress Repair Process
1. A Quick Conversation
Give us a call or fill out the form. We’ll ask a few questions about what’s going on with your system so we can send the right technician with the right parts.
2. Thorough Checkup
Your technician arrives within the scheduled window, inspects the full system, and identifies the root cause, not just the symptoms.
3. Straightforward Pricing
Before any work begins, you get a clear quote. You approve, or you don’t. No surprise charges.
4. Fast, Effective Fixes
Once you give the go-ahead, we get to work. Our trucks carry the most common repair parts, so many repairs are finished on the first visit. If your system needs a part we don't stock, we'll tell you upfront, order it, and schedule the return trip to finish the job.
What Columbia Homeowners Are Saying
What Makes Carolina Comfort Different
Your Technician Is There to Fix Your AC, Not to Sell You a New One
When our technician walks into your home, they have one job: figure out what’s wrong with your AC and fix it. If a repair will keep your system running, that’s what they’ll recommend. If replacement genuinely makes more sense, they’ll show you the numbers and give you time to decide. No pressure, no “today only” offers, no hard close.
If Your Warranty Covers It, We’ll Fight to Make Sure You Don’t Pay for It
Manufacturer warranties cover the part, but not the labor, not the refrigerant, and not the materials it takes to install it. That’s where repair bills add up fast, even on a “covered” system. Carolina Comfort advocates for every valid warranty claim on your behalf. If we believe your repair should be covered, we push for it, because we work for you, not the manufacturer.
Your Tech Has Already Practiced Diagnosing Your Problem
Our Service Manager Randy Mitchell built custom training boards that replicate real-world HVAC failures such as faulty igniters, refrigerant leaks, electrical faults. These are the problems Columbia homeowners actually call about. Every technician on our crew gets one-on-one training sessions on these simulators every week, to practice diagnosing and solving problems before they enter your home. That means faster, more accurate diagnoses on your service call, and fewer return visits to get it right.
The Family That Built This Company Stands Behind Your Repair
Rich Mitchell started Carolina Comfort in 1992. His sons Cole and Randy run it today. Cole manages operations, Randy manages the service team and personally trains every technician on the crew. The same family that built this company 34 years ago is directly overseeing the repair at your house. If something isn’t right, you’re talking to the people who own the business and have 34 years of reputation riding on getting it right.
Frequently Asked Questions

For most calls that come in before noon, we can have a technician at your door the same day. We always give a 1-hour arrival window, not a 4-hour guess. If you’re the first call of the day, we’ll give you a specific time. During peak summer weeks, same-day availability occasionally fills up, but we’ll schedule you next-day as a high priority and call if an earlier slot opens up. Service agreement customers are always scheduled first.
Every repair starts with a $99 diagnostic fee (for homes within 30 miles of our Columbia office). The technician will find the problem, explain what’s wrong, and give you a repair quote before any work begins. You approve the cost upfront. If you decide not to proceed, you owe only the $99 diagnostic. Repair costs beyond the diagnostic depend on the part and the labor involved. Our residential labor rate is $165/hour, and we’ll tell you the expected time before we start.
Yes. We repair Heil, Lennox, Carrier, Trane, Goodman, and ductless systems. If your brand isn’t listed here, call us. We’ve worked on virtually every residential system on the market in our 34 years.
That depends on the diagnosis, and it’s a decision we’ll help you make honestly. If a repair will keep your system running reliably, that’s what we’ll recommend. If your system is old enough or damaged enough that repairs would cost more than they’re worth, we’ll show you the numbers and explain why replacement makes more sense. Either way, you’ll have the information you need to decide without pressure. We don’t push replacements, we fix what we can and explain what we can’t.
Every repair comes with a 30-day warranty. If the part we installed or the work we performed isn’t holding up within that window, we come back and make it right at no additional cost. If your system has a manufacturer’s parts warranty, we’ll handle the claim process and advocate on your behalf to make sure you’re not paying for something that should be covered.

“They came when they said they would, did the work they said they would,
and followed up to verify that I was happy.
Can’t ask for more than that.”
