AC Repair in Greenville. Quick Answer

About Our AC Repair Services in Greenville

Our shop sits at 33 Market Point Dr, which puts a stocked truck within about 30 minutes of most Greenville addresses. We diagnose with gauges, multimeters, and temperature probes, not guesswork, and you get a flat-rate quote before any work starts.

Greenville's older neighborhoods are their own repair category. The 1920s to 1960s homes along Augusta Road, North Main, and the West End often run systems that are past 15 years old, and a fair number still use R-22 refrigerant, which is no longer produced. The mature hardwood canopy that makes those streets beautiful also loads outdoor coils with pollen every spring. Both patterns shape what we find when we open a unit up.

Common AC problems we fix in Greenville

Four failures fill our schedule from May to September. Here is each one, with what fixing it actually costs.

Refrigerant leaks and frozen coils

The big one in Greenville's older housing stock. A system that runs but blows warm air is usually low on refrigerant or running a coil starved for airflow, and pollen-caked outdoor coils in the tree-heavy neighborhoods make it worse. A leak search plus recharge runs $250 to $1,500 depending on severity. If your system still uses R-22, we will walk you through whether a recharge is worth it before you spend the money, because that refrigerant is no longer produced and the math often favors replacement.

Run capacitors

The most common single repair we do anywhere in the Upstate. The capacitor gives your compressor and fan motors their starting jolt, and 1,000-plus hours of runtime per cooling season cooks them. The fix runs $150 to $400, the part is on the truck, and your system is usually cooling again before we leave.

Contactors

The electrical switch that tells your outdoor unit to run. After thousands of cycles the contacts pit and burn, and the unit either will not start or will not stop. Another same-visit repair in most cases.

Clogged condensate drains

Greenville humidity grows algae in drain lines all summer. When the line clogs, the float switch shuts the system down before the pan overflows into your ceiling, which is annoying but correct. Clearing a clog starts at $129. A full drain line rebuild can reach $500.

If your home has a crawlspace, ask us to look while we are there. Crawlspace humidity rusts coils and drain pans from the outside in, and we photograph what we find so you can see it yourself. No obligation to act on any of it.

Same-day AC repair, no after-hours upcharge

Morning calls usually get same-day service anywhere in Greenville. During a July heat wave it may be the next morning, but we reach every call within 24 hours.

Nights and weekends cost the same as a Tuesday afternoon. Most Upstate companies charge 1.5 to 2 times their standard rate after hours. We never have.

Repair or replace?

Multiply the system's age by the repair cost. Over $5,000, and replacement usually makes more financial sense. A $1,200 repair on a 6-year-old system is worth doing. The same repair on a 17-year-old R-22 system in an Augusta Road bungalow usually is not, because the next failure is already on its way and the refrigerant alone makes every future repair expensive.

You get real numbers for both paths and you make the call. If the repair makes more sense, we will say so, even when it costs us a sale. Replacement estimates are free and financing is available.

I called First Class Heating & Air for a second opinion after another company could not find the part they said my unit needed. After finding that my system did Not need the part, First Class fixed the leak and replaced the refrigerant at less than half the cost of the other company's estimate. I appreciate companies being honest and upfront with customers. They also kept me updated every step, day before and day of service. I will be calling First Class Heating & Air for both of my properties and sending others their way!

Local Pro Tip. Greenville

If your house sits under Greenville's older hardwood canopy, rinse the outdoor coil with a garden hose each April after the yellow pollen wave passes. Pollen mats on the coil make the system work harder all summer, and it is the single cheapest thing you can do to prevent a frozen coil in July.

AC Repair FAQ. Greenville, SC

Answers to common questions about AC repair in Greenville.

How much does AC repair cost in Greenville?

The diagnostic visit puts gauges on the system, runs a full performance test, and gets you a flat-rate quote before any work starts. Most repairs land between $150 and $1,500. A run capacitor, the most common fix, runs $150 to $400.

Can you fix my AC today in Greenville?

Usually, yes, especially if you call in the morning. Our shop is on Market Point Dr, so most Greenville addresses are within a 30-minute drive. During peak heat waves it may be the next day, but we reach every call within 24 hours.

My AC runs but the house will not cool down. What is wrong?

In Greenville the usual suspects are a refrigerant leak, a frozen coil from restricted airflow, a failed capacitor, or a tripped float switch from a clogged drain line. Check your air filter first. All four are same-visit fixes in most cases.

Is it worth recharging an R-22 system?

Sometimes, but often not. R-22 is no longer produced, so recharges are expensive and every future leak costs more. We put the recharge number next to the replacement number and let you decide. Many owners of older Greenville homes are surprised how close the math gets.

Do you charge more for nights, weekends, or holidays?

No. Same flat rate every day of the year. The price we quote is the price you pay.

Recent work in Greenville

5 jobs our technicians have finished around Greenville. Tap a pin to see the photo and what the work involved. Locations are approximate. We place each job to the neighborhood, never to a customer's door.

  • Cleaned condenser coil, plugged mis-routed secondary drain, off Westchester Road, Greenville, SC. During a tune-up, the condenser coil was found dirty and got cleaned so the system could move air properly again. We also noticed the secondary drain on the evaporator coil had never been plugged off correctly, which let water run out underneath the house. That drain is now sealed to stop the leakage. While testing, the condenser fan capacitor came back weak. The system is running fine for now, but that capacitor is worth replacing before it fails outright.
  • Fixed a mis-plumbed secondary drain line, off Meyers Court, Greenville, SC. Found the secondary drain on the main pan wasn't installed right and hadn't been plugged, so water was dripping out where it shouldn't. On top of that, the secondary pan under the unit wasn't capped, which let water in that pan run straight onto the ceiling below. We corrected the drain setup and capped the pan so water goes where it's supposed to instead of into the ceiling.
  • Topped off refrigerant on an aging R-22 system, off Verdun Avenue, Greenville, SC. This Goodman system was low on charge and not cooling like it should. We hooked up gauges and found the pressures well below where they needed to be. Added a pound of R-22 and the system came back up to proper operation, cooling normally again. That said, this unit has a refrigerant leak somewhere in the system, so this fix is a temporary one. R-22 is an older refrigerant that's being phased out, and repeated topping off isn't a long-term solution. System replacement recommended
  • Replaced a failed capacitor to restore cooling, off Mary Street, Greenville, SC. This system had stopped cooling, and a check of the outdoor unit found the problem: a failed 35/5 µF capacitor. That part is what gets the compressor and fan motor started, so once it fails the system can't run. We swapped in a new capacitor, then checked the compressor and fan motor amp draws against their rated loads, inspected the contactor, and checked the refrigerant pressures. Everything came back within spec. Cooling was restored and the system was left running properly.
  • Replaced a failed capacitor on a Lennox condenser, off Old Augusta Road, Greenville, SC. The upstairs system had stopped cooling, and the outdoor unit checked out with a bad 35/5 dual run capacitor. That part gives the compressor and fan the jolt they need to start up, so once it fails the unit either won't start or struggles to run. We swapped in a new capacitor and confirmed the system was pulling proper charge and pressures afterward. It's back up and cooling normally.
