Before you hire an AC pro in Greenville SC, check five things: a current South Carolina HVAC license, general liability and workers' comp insurance, EPA 608 certification for anyone handling refrigerant, a local review history that mentions the exact work you need, and a written price before any tool comes out of the truck. Those five checks take about fifteen minutes and eliminate almost every bad outcome we get called to clean up.
This post walks through each one, tells you where to look, and lists the questions that separate a real AC company from a guy with a gauge manifold and a magnetic sign.
Verify the South Carolina license before anything else
South Carolina requires mechanical contractors who perform HVAC work to hold a state license issued through the South Carolina Contractor's Licensing Board, and you can look that license up in about two minutes. Ask for the license number, then verify it yourself rather than trusting a logo on a truck door.
Licensing matters because it confirms the contractor passed a trade exam, carries the required bond, and can legally pull the permits that a compressor swap or full system replacement needs. Unlicensed work can void your homeowner's insurance claim if a fire or water damage traces back to the install.
Two license classes cover most residential work in Greenville County. A Mechanical Contractor license handles HVAC installation and repair. A General Contractor with an HVAC subclassification can also do the work on larger projects. Either is fine. What is not fine is a handyman who says he "does AC on the side."
If the person you are talking to cannot produce a license number on the spot, that is your answer. Move on.
Check insurance and workers' compensation
Ask for a certificate of insurance showing general liability coverage and workers' compensation, and call the agent listed on the certificate to confirm it is active. A certificate is a one-page PDF; anyone can print one. A two-minute call to the insurer is the only way to know the policy has not lapsed.
Here is why this matters in practice. If a technician falls off a ladder in your attic and the company has no workers' comp, your homeowner's policy can end up on the hook. If a tech cracks your condenser coil with a wrench and the company has no liability coverage, you are negotiating with a sole proprietor who may not have the cash to replace a $1,800 unit.
Minimum coverage we would want to see for residential AC work in Greenville: $1 million general liability and an active workers' comp policy. Anything less and the risk shifts to you.
Confirm EPA 608 certification for refrigerant work
Federal law requires anyone who buys, handles, or recovers refrigerant to hold EPA Section 608 certification, and this applies to every AC tech who touches your system's sealed circuit. Ask which certification level the technician holds. Type I covers small appliances. Type II covers high-pressure systems, which is what your home's split system or heat pump uses.
This is not a paperwork formality. Refrigerant recovered without certification is illegal to vent, and a tech who skips recovery is also likely to skip the leak search that tells you why the system lost charge in the first place. We see this constantly: a system gets topped off every spring by someone without certification, and nobody ever finds the leaking Schrader valve or the rubbed line under the insulation.
If you want to see what proper refrigerant work looks like, our page on AC refrigerant leak repair Greenville SC walks through the electronic leak detection and nitrogen pressure test we run before we add a single ounce of charge.
Read reviews the way a neighbor would
Reviews are useful only if you read them for the specific job you need done, not the star average. A company with 4.8 stars from 300 tune-up customers may have never replaced a compressor in its life.
Search the review text for the words that match your problem: "compressor," "capacitor," "not cooling," "emergency," "weekend." Then look at how the company responded to the one-star reviews. Every AC company in Greenville has a bad review or two. What matters is whether the owner replied with a specific fix or a generic apology.
Cross-check the address. A company listing a UPS Store mailbox as its business address is likely a lead-generation call center that subcontracts to whoever answers the phone. You want a shop you can drive to.
Local matters here for a practical reason. Greenville summers push attic temperatures past 140°F, and the humidity off the Reedy River basin works on condensate lines and drain pans all season. A company that has been servicing homes in residential AC repair Greenville SC for years has already seen how those conditions fail specific components, and they stock the parts.
Get pricing in writing before work starts
Ask for a written price before any technician starts work, and ask specifically whether the diagnostic fee is credited toward the repair. Typical 2026 pricing in Greenville runs $79 to $129 for a diagnostic visit, $180 to $450 for a capacitor or contactor replacement, and $1,400 to $2,600 for a compressor replacement including labor and refrigerant. If a quote lands far outside those ranges in either direction, ask why.
Three pricing red flags to watch for:
- A "free inspection" that turns into a same-day four-figure repair pitch before you have had time to think.
- A quote given verbally with no itemized parts and labor breakdown.
- Pressure to sign a service agreement on the spot to "lock in today's rate."
None of those are illegal. All of them make it harder for you to compare bids, which is the point.
One more thing: ask whether the price includes the permit if the job requires one. A full system replacement in Greenville County generally does. If the contractor says permits are not needed for a swap-out, that is a sign they are not pulling them.
What should I ask an AC pro in Greenville before I hire them?
Ask these seven questions and write down the answers. Any hesitation on the first three is a deal-breaker.
- What is your South Carolina license number, and what class is it?
- Can you email me a certificate of insurance today?
- Which EPA 608 certification does the technician who will be at my house hold?
- Is the diagnostic fee credited toward the repair if I approve the work?
- Do you stock common parts for my brand on the truck, or will I wait on a warehouse order?
- How long is the labor warranty on the repair?
- Who do I call if the same problem comes back in two weeks?
Question five is the one most homeowners skip, and it is the one that decides whether your AC is back on tonight or Thursday. If you own a system from a major brand, ask whether they carry the specific parts. We keep common boards and motors for Carrier AC repair Greenville SC and most other major brands on the truck, which is why a lot of our repairs finish in a single visit.
Question six matters more than people expect. A one-year parts warranty with a 30-day labor warranty means you pay the labor again if the same part fails in month three. Ask for the labor term in writing.
Common mistakes Greenville homeowners make
The most expensive mistake we see is hiring on price alone during a July heat wave. When your house is 88°F at 9 p.m. and the kids cannot sleep, the lowest bid looks like the right bid. It rarely is.
Other mistakes that cost Greenville homeowners real money:
- Paying a deposit in cash before any work starts. A legitimate AC company does not need your cash up front for a capacitor or a blower motor.
- Letting a tech add refrigerant without finding the leak. A sealed system does not consume refrigerant. If it is low, it is leaking, and a top-off buys you weeks, not years.
- Skipping the permit on a system replacement. When you sell the house, an unpermitted install can stall the inspection and cost you more than the permit did.
- Believing "we service all brands" means they stock parts for yours. It usually means they will order the part and come back.
- Not asking about after-hours rates. A 2 a.m. call in August can carry a $150 to $300 premium over the same repair at 10 a.m.

When to call a professional
Call a professional when the breaker trips twice in a row, when you see ice on the copper line at the outdoor unit, when the compressor hums but does not start, or when the system has not cooled the house within 30 minutes of a thermostat call. Those four symptoms point to electrical or refrigerant faults that get worse, not better, if you keep running the system.
You can safely handle the easy stuff yourself: replace the filter every 60 to 90 days, clear debris from around the condenser, and check that the outdoor disconnect is seated. Beyond that, the tools and the refrigerant handling get expensive fast.
Our team at Greenville AC Repair Pros works on every major residential system in the area, from a 20-year-old builder-grade unit in a Taylors ranch to a new variable-speed heat pump in a Simpsonville subdivision. We diagnose first, quote the repair in writing, and only then start work.
Frequently Asked Questions
What should I check before hiring an AC pro in Greenville SC?
Check five things: a current South Carolina mechanical contractor license, active general liability and workers' comp insurance, EPA 608 certification for the technician, local reviews that mention your specific repair, and a written price before work starts. Those five checks take about 15 minutes and filter out nearly every problem contractor.
How do I verify an AC pro's license in Greenville?
Ask for the license number, then look it up through the South Carolina Contractor's Licensing Board's online search. Confirm the license is active, matches the company name on the truck, and covers mechanical or HVAC work. If the contractor cannot give you a number within a few minutes, do not hire them.
What questions should I ask an AC pro in Greenville South Carolina?
Ask for the license number and class, a certificate of insurance, the technician's EPA 608 level, whether the diagnostic fee is credited toward the repair, how long the labor warranty runs, and whether they stock parts for your brand. Get the answers in writing before you approve any work.
How do I avoid AC repair scams in Greenville?
Never pay a cash deposit before work starts, never approve a repair without an itemized written quote, and never let anyone add refrigerant without first finding the leak. Verify the license and insurance yourself. A legitimate AC company will hand over all of that without hesitation.
Does an AC repair company in Greenville need to pull a permit?
For a like-for-like part swap, usually no. For a full system replacement or any work that alters the refrigerant circuit or electrical feed, Greenville County generally requires a mechanical permit. Ask who pulls it and confirm it is included in the quoted price.
