    AC Repair in Greenville. Quick Answer

    AC repair in Greenville starts with a diagnostic visit, and most repairs land between $150 and $1,500. We cover all of Greenville, from the Woodruff Road corridor to North Main.

    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.

    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 and Air for a simple checkup on my system. Everything had been working fine so I didn’t necessarily have any concerns about the unit. Well, the technician found that there was a train missing from the unit and water was being released into my crawlspace! Granted the moisture levels were ok, but my goodness! What if that hadn’t been discovered? Anyway, they completed the tuneup, installed the drain etc all in under an hour and it was affordable. I recommend 11 times out of 10

    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.

    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.

    • Tune-up catches two weak capacitors on three furnaces, off East Camperdown Way, Greenville, SC. We went through heating maintenance on all three furnaces at this property: main house, upstairs, and guest house. Checked inducer motors, capacitors, igniters, flame sensors, and blower motors on each system. On the main house furnace, the inducer motor's capacitor was weak and leaking oil, so we replaced it. In the guest house, the blower motor's capacitor had also gone weak and got replaced. The upstairs furnace just needed a gas pressure adjustment to bring it to spec. All three systems are heating properly now. We also flagged some air leakage at the main house supply plenum for a separate repair quote.
    • Replaced crushed return duct, fixed airflow problem, off Elmwood Avenue, Greenville, SC. The return duct feeding this 3 ton system was crushed down to a 16 inch line, choking off airflow and causing the system to freeze up. We pulled it out and installed a new 18 inch R-8 insulated return, sized correctly for the unit, and sealed it in with mastic. We also replaced a 10 inch duct connecting the two return boxes with a custom sheet metal transition built to match the box openings, so the second return can pull its full share of air. After install we re-tested static pressure and checked airflow and temperature split to confirm the system was running the way it should.
    • 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.
