How it works
Your AC quit. Here's what happens next.
When you call (615) 412-2495, a real person will ask what's going on and get a technician to your door. Most Gallatin breakdowns come down to a short list: a failed capacitor, a worn contactor, a refrigerant leak, a frozen coil, or a clogged drain. Our job is to find which one, prove it with test readings, and fix it. At Gallatin HVAC Repair Pro, that's the business model: honest answers first, repairs second, replacement only if it's genuinely the smart move.
Middle Tennessee summers are brutal on air conditioners. Long runtimes, afternoon thunderstorms that knock power out, and the damp air drifting off Old Hickory Lake all take a toll. If you're wondering why your AC is blowing warm air, you're not alone. It's the most common call we get from late May through September.
Symptoms we fix every day
Runs nonstop, won't cool
The unit never satisfies the thermostat. Often airflow or refrigerant related.
Won't turn on at all
Dead silence or a hum with no start. Often a failed capacitor or contactor.
Short cycling
Kicks on and off every few minutes. Wastes energy and wears parts fast.
Strange noises
Grinding, buzzing, rattling, or squealing from inside or outside the house.
Ice on the lines
Frost on the copper lines or coil. Turn it off, let it thaw, then call us.
Water leaking inside
A clogged condensate drain can shut the system down or damage ceilings.
Breaker keeps tripping
An electrical fault is forcing the breaker to protect the circuit. Don't keep resetting it.
No guesswork
What's included in our diagnostic visit
A diagnostic is the most important part of the job: getting the diagnosis right is what keeps you from paying for parts you don't need.
- Full system walkthrough: we inspect the thermostat, filter, indoor coil, blower, outdoor unit, electrical connections, and drain line.
- Real measurements: capacitor ratings, voltage and amperage draws, refrigerant pressures, and temperature split across the coil.
- Show, don't tell: we'll show you the failed part and explain the readings in plain language.
- Written options: you get your repair choices with clear pricing before we touch a wrench.
- Honest verdict: if the fix is simple, we say so. If the system is on its last legs, we'll tell you that too and explain why.
That's the repair-first promise Gallatin HVAC Repair Pro was built on. Plenty of second-opinion calls end with a repair costing a few hundred dollars, not a few thousand.
Under the hood
The usual suspects: what actually fails on Gallatin ACs
Your air conditioner moves heat from inside your home to outside, over and over, all summer. If you're curious, this is a good plain-language explainer of how air conditioning works. The parts that fail most often are the ones doing the hardest work:
Start capacitors
A capacitor is a small cylinder that stores the jolt of energy needed to start your compressor and fan motors. Heat and voltage spikes wear them out, and when one dies, the motor it serves just hums. It's one of the most common and least expensive repairs we make.
Contactors
The contactor is the electrical switch that feeds power to the compressor and outdoor fan. Burned or pitted contacts can cause chattering, no-starts, or a unit that runs when it shouldn't. We see a lot of these after storm season.
Refrigerant leaks
Refrigerant runs in a sealed loop, so low refrigerant always means a leak. Topping it off without finding the leak is money down the drain, and it's why some homeowners get charged for refrigerant year after year. We find the leak, repair it when practical, and recharge to spec.
Frozen evaporator coils
A frozen coil looks dramatic, but the causes are ordinary: a filthy filter, a blocked coil, a weak blower, or low refrigerant. Running the system while it's iced over can slug the compressor with liquid, so shut it down and let it thaw.
Before you call
What should I check myself first?
We'd rather talk you through a free phone fix than charge for a visit you didn't need. Safe checks:
- Thermostat: set to COOL, temperature below room temp, fan on AUTO. The fan ON setting can make air feel warm between cooling cycles. Here's more on the thermostat fan ON vs. AUTO question.
- Filter: a clogged filter chokes airflow and can freeze the coil. If you can't see light through it, replace it. ENERGY STAR notes that a dirty filter is one of the most common causes of poor cooling.
- Breaker: check the panel once. If it trips again, stop resetting it and call us.
- Outdoor unit: clear grass, leaves, and mulch at least two feet back so it can breathe.
- Ice: if the lines are frozen, turn the system off, leave the fan on, and give it a few hours to thaw.
Where to stop: don't open electrical panels, don't touch capacitors (they hold a charge even with power off), and don't mess with refrigerant lines. Refrigerant handling requires EPA-certified training, and 240-volt mistakes are unforgiving. That's what we're here for.

Common questions
AC repair questions Gallatin homeowners ask us
The usual causes are simple: the thermostat is set wrong, the filter is clogged, the indoor coil has frozen over, or refrigerant has leaked out. Check that the thermostat is on COOL with the fan set to AUTO, and put in a clean filter. If it still blows warm air, schedule a diagnostic visit. Guessing at parts is how small problems turn into big bills.
Yes. Capacitors are one of the most common air conditioner repairs we make, and they are one of the least expensive. A capacitor stores the jolt of energy that starts your compressor and fan motors, and Tennessee heat and storms wear them out over time. An honest technician will show you the failed part and the test readings before you agree to anything.
Because it has a leak. Air conditioners do not consume refrigerant; it circulates in a sealed system, so a system that is low again this year has refrigerant escaping somewhere. Topping it off without fixing the leak means you will pay for refrigerant again next season. We locate the leak, repair it when practical, and recharge the system to the manufacturer's specification.
Five safe checks: confirm the thermostat is on COOL with the fan on AUTO, replace a dirty filter, check the breaker, clear leaves and grass away from the outdoor unit, and if you see ice on the lines, turn the system off and let it thaw. Leave electrical panels, capacitors, and refrigerant lines alone. Those need a trained technician and the right tools.
Ice forms when something disrupts the normal heat-exchange cycle: restricted airflow from a dirty filter or blocked coil, a failing blower, or low refrigerant from a leak. Turn the system off but leave the fan on to thaw it, then check the filter. If ice comes back, there is an underlying problem that needs a technician to diagnose.
