The short answer
Thermal Services repairs central air conditioners, heat pumps and gas packs in Rock Hill, Fort Mill, Tega Cay, Indian Land and the surrounding area. We diagnose the actual cause, explain it in plain English, and give you the price before any work starts. Call (704) 701-6478, Mon–Sat 9–6.
Reviewers keep using the same words about us: honest, fair, never pushy. That matters most on a repair call, when you're hot, tired, and trusting someone to tell you what's actually wrong.
What we fix
- No cooling at all: failed capacitors, contactors, fan motors, tripped safeties, thermostat and wiring faults.
- Running but not keeping up: low refrigerant and leaks, dirty coils, airflow and blower problems.
- Frozen coils and iced lines: finding out whether it's airflow, charge or the blower, and fixing the cause.
- Water leaks: clogged condensate drains, failed condensate pumps, cracked or rusted pans.
- Noises and smells: worn motor bearings, loose panels, electrical burning smells.
How a repair visit goes
- You call and tell us what it's doing. The more detail, the better we can prepare.
- We diagnose it. Pressures, temperatures, electrical readings, airflow. Not guesses.
- We explain it and give you the price. If a repair makes sense, we say so. If the system is at the end of its life, we'll say that too, and you decide.
- We fix it and clean up. Customers mention that we leave work areas neater than we found them.
Repair or replace?
We'd rather keep a good system running than sell you a new one. As our original website put it, our expertise is in keeping your current unit running as long and as efficiently as possible. When replacement does make more sense, we'll show you why. See AC installation and replacement.
Before you call, a few checks can save you a visit: AC running but not cooling.
Common questions
What are the most common AC repairs in Rock Hill?
In a Carolina summer, the parts that fail most are run capacitors, contactors, outdoor fan motors and clogged condensate drains. Refrigerant leaks and frozen coils are next. Most of these can be diagnosed in one visit, and many are fixed the same day if the part is on the truck.
Is it worth repairing an old air conditioner?
Often, yes. A capacitor or contactor on a 14-year-old system is an inexpensive fix. It gets harder to justify when the compressor fails, the system uses R-22, or the repairs keep coming. We'll tell you plainly which side of that line you're on.
Do you work on all brands?
Most of the equipment we install is Rheem, but repair calls come in on whatever is in the house. Call and tell us what you have.
Should I keep running my AC if it's making a buzzing noise?
No. A buzz or hum at the outdoor unit with the fan not spinning often means a failed capacitor. Running it that way can overheat the compressor. Turn it off at the thermostat and call.
