AC frozen evaporator coil repair Greenville SC that restores cold air fast
Thaw, clean, and recharge your frozen coil before the compressor fails
When your evaporator coil ices over, the whole system stops cooling and the compressor starts taking damage. Our AC frozen evaporator coil repair Greenville SC service thaws the coil, finds the root cause, and restores full cooling the same visit. We handle frozen AC repair Greenville SC for homes and businesses across Greenville County, from Downtown to Berea. Call (903) 627-1334 and we will get your air cold again.
AC frozen evaporator coil repair Greenville SC explained
AC frozen evaporator coil repair Greenville SC is a diagnostic and mechanical service that thaws an iced-over indoor coil, then corrects whatever caused the freeze so it does not return. The evaporator coil sits inside your air handler and absorbs heat from your home's air. When airflow drops or refrigerant pressure falls, the coil surface drops below 32 degrees and condensation turns to solid ice. We use a manifold gauge set to read pressures, a clamp meter to test the blower motor and run capacitor, and a fin comb to straighten bent coil fins before we clean and restart the system.
Most frozen coils in Greenville trace back to a clogged air filter, a weak blower motor, or a slow refrigerant leak. Our humidity runs high from April through September, so a coil that is only slightly restricted will ice up fast. If you search for frozen evaporator coil fix near me Greenville, you want a technician who thaws the coil completely instead of just turning the thermostat up. We pressure-test the circuit, check the condensate drain line, and confirm the coil is dry before we leave.
Why Greenville homeowners call us for frozen coils
A frozen coil is not a small inconvenience. It stops cooling, raises your power bill, and can destroy a compressor that costs more than the repair itself. Here is what you get when you call us.
Cooling restored same day
We thaw the coil, correct the airflow or charge problem, and verify a 18-22 degree temperature split at the supply and return. Most frozen AC repair Greenville SC calls are finished in two to four hours, so you sleep in a cold house that night.
Compressor protected
A frozen coil forces the compressor to run hot and slug liquid refrigerant. We test the run capacitor, contactor, and compressor windings with a multimeter before restart, so a $180 repair does not turn into a $1,900 compressor replacement.
Root cause found, not guessed
We use a leak detector and manifold gauge set to separate airflow problems from refrigerant loss. That means we fix the actual cause, whether it is a clogged air filter, a failing blower motor, or a pinhole leak in the evaporator coil.
Drain line cleared and treated
Thawing a coil dumps a quart or more of water into the drain pan. We flush the condensate drain line, add drain pan tablets, and confirm the pan empties, so you do not trade a frozen coil for water damage in the ceiling.
Our frozen coil repair process
You get a clear sequence from the first call to the final temperature check. No guesswork, no surprise add-ons, and no leaving a coil half-thawed.
Phone triage
We ask what your thermostat reads, whether the outdoor unit is running, and how long the system has been icing. That tells us whether to bring a recovery machine and refrigerant or just thaw and clean. You get a two-hour arrival window and a call when the technician is on the way.
System inspection
The technician pulls the air filter, opens the air handler, and confirms the ice depth on the evaporator coil. We check the blower motor amp draw with a clamp meter and test the run capacitor and contactor. This takes 15 to 20 minutes and tells us whether the freeze is airflow or refrigerant related.
Thaw and clean
We thaw the coil with controlled airflow, never a heat gun that can crack the tubing. Once clear, we clean the coil with a coil cleaning pump sprayer, comb bent fins, and flush the condensate drain line. Expect 45 to 90 minutes depending on ice thickness.
Repair and recharge
If we find a refrigerant leak, we repair it, pull a vacuum with a vacuum pump, and recharge to the manufacturer's weight using R-410A or R-32. If the problem is a failed blower motor or capacitor, we replace it on the spot. Most repairs add one to two hours.
Verify and advise
We run the system for 20 minutes and measure the supply and return temperatures. You get a written summary of what froze the coil and what filter or maintenance schedule prevents a repeat. We do not leave until the coil is dry and the temperature split is in range.
Frozen coil expertise you can check
Our technicians hold EPA Section 608 certification for refrigerant handling and NATE certification for air conditioning diagnostics. We carry a South Carolina HVAC contractor license and a Greenville County business license, and we keep manufacturer certifications current with Carrier, Trane, and Lennox equipment. That matters on a frozen coil because the fix depends on reading pressures and airflow together, not swapping parts until something works. We work on every major brand, including Goodman, Rheem, York, American Standard, Amana, Daikin, Mitsubishi Electric, Bryant, and Payne.
- EPA Section 608 certified for refrigerant recovery, vacuum, and recharge on every frozen coil job
- NATE-certified diagnostics for airflow, capacitor, and blower motor testing
- Carrier, Trane, and Lennox manufacturer certifications for warranty-safe coil repairs
- SC HVAC contractor license and Greenville County business license on file
- OSHA safety certification for attic and crawlspace air handler work
Why our AC frozen evaporator coil repair Greenville SC stands out
We are a local Greenville company, not a call center. The technician who answers your questions is the one who thaws your coil, and the price we quote on the phone is the price you pay.
Same-day frozen coil service
We hold same-day slots for frozen coils because ice does not wait. Call before noon and we can usually be at your door by late afternoon. Our trucks carry R-410A, R-32, run capacitors, contactors, and blower motors, so most repairs finish in one visit.
Upfront pricing before work
You get a flat diagnostic fee and a repair price before we start. A thaw and clean runs $180 to $320, and a leak repair with recharge runs $450 to $1,100. No hourly surprises, no parts markup revealed at the end.
We fix the cause, not the symptom
Turning the thermostat to fan-only thaws ice but leaves the cause in place. We test static pressure, refrigerant charge, and blower amp draw so your AC frozen coil service Greenville solves the problem the first time instead of every three weeks.
Greenville County local knowledge
Homes in Nicholtown, Sterling, and Gower often have undersized return ducts that starve the coil. Houses near Paris Mountain and Furman run longer cycles in summer humidity. We size the fix to the house, not to a generic checklist.
What our frozen coil service includes
Every frozen coil visit includes thawing, diagnosis, and a written cause report. Parts and refrigerant are quoted separately once we know what failed, and you approve the price before we install anything.
What's Included
Full coil thaw
We thaw the evaporator coil completely using controlled airflow, then dry the coil and drain pan. Rushing this step cracks tubing and floods your ceiling, so we take the 45 to 90 minutes it takes to do it right.
Airflow and charge diagnosis
We measure blower motor amp draw, static pressure, and refrigerant pressures with a manifold gauge set. That separates a clogged filter or weak blower from a true refrigerant leak, which changes the repair and the price.
Coil cleaning and fin combing
A dirty coil freezes faster. We clean the evaporator coil with a coil cleaning pump sprayer, comb bent fins, and rinse the drain pan. Clean coils also cut your cooling cost by improving heat transfer.
Condensate drain flush
Thaw water has to go somewhere. We flush the condensate drain line, add drain pan tablets, and confirm the pan drains freely. A clogged drain line is the second most common reason we get called back.
Temperature split verification
Before we leave, we run the system and measure supply and return air. An 18-22 degree split confirms the coil is working. If it is not, we keep diagnosing until it is.
Frozen coil problems we solve in Greenville
Ice on the coil shows up in a few predictable ways. Here is what Greenville homeowners describe when they call, and what we do about each one.
AC blowing warm air with ice on the indoor unit
The coil cannot absorb heat through ice, so the house warms up while the compressor runs hot and draws higher amps.
We thaw the coil, then test the blower motor, run capacitor, and filter restriction. In most Greenville homes the culprit is a clogged filter or a failing blower motor, and we replace it the same visit.
Ice returns within a week of thawing
A slow refrigerant leak or an undersized return duct will refreeze the coil, and repeated freeze cycles shorten compressor life.
We pressure-test the circuit with a leak detector, repair the leak, pull a vacuum, and recharge by weight. If ducting is the cause, we measure static pressure and recommend the return fix that stops the freeze.
Water leaking around the air handler
A thawed coil sends water into a drain pan that may be clogged, and overflow damages ceilings, insulation, and flooring.
We flush the condensate drain line, treat the pan with drain pan tablets, and check the pan slope. If the drain line is badly scaled, we clear it with a pump sprayer and confirm flow before we leave.
AC short cycling after a freeze
A frozen coil can trip the safety switch and cause the system to cycle on and off, which wears the contactor and compressor.
We test the contactor, thermostat, and capacitor, then confirm the coil is fully thawed and the safety switch is reset. Most short cycling stops once the coil and charge are corrected.
When to call for frozen coil repair
A Downtown Greenville condo tenant calls in July because the AC runs all day but the unit stays at 78 degrees.
We thaw the coil, find a completely clogged air filter and a blower motor drawing high amps, replace the motor and filter, and clean the coil.
The condo drops to 72 degrees within an hour, and the tenant avoids a compressor failure that would have cost the owner over $1,800.
A West End homeowner notices ice on the copper lines in October and wants AC coil frozen Greenville checked before winter.
We thaw and clean the coil, find a slow refrigerant leak at a flare fitting, repair it, and recharge with R-410A to the manufacturer's weight.
The system holds pressure, the coil stays clear, and the homeowner starts heating season with a working heat pump instead of a dead compressor.
A property manager in Haywood Road has three units icing over in the same week.
We schedule same day frozen coil repair Greenville SC for all three, thaw and clean each coil, and find that two have failed run capacitors and one has a restricted return.
All three units return to a 20 degree temperature split, and the manager sets a quarterly filter and drain line schedule to prevent repeats.
A Berea family wakes up to water on the floor and a frozen air handler in August.
We thaw the coil, clear a badly clogged condensate drain line, replace the drain pan tablets, and test the blower and capacitor.
The floor dries, the drain flows freely, and the AC holds 74 degrees through the rest of the summer without another freeze.
Tools and methods we use
Tools & Equipment
Manifold gauge set
Reads high and low side refrigerant pressures so we can tell a low charge from a restricted metering device before we add refrigerant.
Clamp meter and multimeter
Tests blower motor amp draw, run capacitor microfarads, and contactor voltage. High amp draw on a blower motor is a common cause of low airflow and coil freeze.
Leak detector
Finds pinhole leaks in the evaporator coil and line set. A slow leak is the second most common reason a coil freezes in Greenville.
Vacuum pump and recovery machine
Recovers refrigerant and pulls a deep vacuum before recharge. Skipping this step leaves moisture in the system and causes repeat failures.
Coil cleaning pump sprayer and fin comb
Applies coil cleaner and straightens bent fins. Clean, straight fins transfer heat better and freeze less often.
Nut driver set and flaring tool
Opens air handler panels and makes flare connections on line set repairs. Clean flare work prevents the leaks that cause freeze-ups.
Methods & Techniques
EPA Section 608 refrigerant handling
Every technician who touches refrigerant is EPA Section 608 certified. We recover, evacuate, and recharge by weight, never by guess, which keeps your coil and compressor running to spec.
NATE-certified airflow diagnostics
We measure static pressure and temperature split, not just pressures. That is how we catch undersized returns and weak blower motors that a pressure reading alone would miss.
Manufacturer charge charts
We recharge to the Carrier, Trane, Lennox, Goodman, or Rheem chart for your exact model. Overcharging a coil causes the same freeze problem you called us about.
ACCA quality standards
We follow ACCA installation and service standards for airflow and charge verification. That gives you a documented baseline for the next technician who touches the system.
How frozen coil repair runs in Greenville
Greenville summers push dew points into the 70s, and that humid air is what turns a slightly restricted coil into a solid block of ice. Homes in Downtown Greenville, the West End, and North Main often have air handlers in tight closets with little return air, so the coil starves and freezes. Older houses in Nicholtown, Sterling, and Gower frequently run undersized return ducts, and we measure static pressure to prove it before recommending duct work. Newer construction near Haywood Road and Cherrydale usually has adequate ducting, so the freeze is more often a refrigerant leak or a failed run capacitor. We work across Greenville County and carry R-410A, R-32, and legacy R-22 handling equipment. If you need affordable frozen coil repair Greenville, call (903) 627-1334 and we will thaw, diagnose, and repair in one visit.
Service Areas
Condos and older homes with closet air handlers and limited return air. We see more airflow-related freezes here and check filter size and blower amp draw first.
Larger older homes with long duct runs. Static pressure testing often shows a restricted return that starves the coil during July and August.
A mix of older and newer homes where we commonly find clogged condensate drain lines and dirty coils that freeze during the first hot week of summer.
Homes at higher elevation run longer heating and cooling cycles. We check charge and blower performance carefully because small faults show up faster here.
Local Considerations
High summer humidity across Greenville County
Humid air condenses on the coil faster, so a coil that is only slightly restricted can ice over in a day. We clean and comb fins to keep airflow high.
Older housing stock with undersized returns
Restricted return air drops coil temperature below freezing. We measure static pressure and recommend a return fix when that is the cause.
Attic and crawlspace air handlers
Greenville homes often place air handlers in hot attics, which stresses blower motors and capacitors. We test both on every frozen coil call.
Pollen and dust seasons
Spring pollen and fall dust clog filters quickly. A filter that is 80 percent loaded is enough to freeze a coil, so we check it first.
Downtown condo frozen solid in July
A tenant called with the AC running nonstop and the condo stuck at 78 degrees. The air handler was packed with ice, the filter had not been changed in over a year, and the blower motor was drawing 4.2 amps against a 2.8 amp rating.
We thawed the coil, replaced the blower motor and filter, cleaned the coil, and verified a 20 degree temperature split. The condo held 72 degrees the same afternoon.
Maintenance & Follow-up
Change the filter every 60 days and have the coil cleaned each spring. A $12 filter is the cheapest insurance against a repeat freeze.
A homeowner had the coil thawed by another company in June. It froze again in three weeks. Our leak detector found a pinhole in the evaporator coil, and the system was 14 ounces low on R-410A.
We repaired the leak, pulled a vacuum with a vacuum pump, and recharged by weight. The coil has stayed clear for two full cooling seasons.
Maintenance & Follow-up
We check pressures each spring. A slow leak shows up as a small pressure drop long before the coil freezes again.
A property manager had three units short cycling and icing over in the same week. Two had failed run capacitors, and one had a return duct that was 40 percent undersized for the tonnage.
We replaced both capacitors, thawed and cleaned all three coils, and corrected the return. All three units now hold an 18-22 degree split and no longer trip.
Maintenance & Follow-up
Quarterly filter changes and an annual capacitor and drain line check keep all three units out of the emergency queue.
What frozen coil repair costs
Typical 2026 pricing in Greenville runs $180 to $320 for a thaw and clean, and $450 to $1,100 when a leak repair and recharge are needed. A failed blower motor adds $350 to $650 installed. We quote the diagnostic fee and the repair price before we start, so you decide with real numbers. If you want affordable frozen coil repair Greenville without a surprise invoice, call (903) 627-1334.
Pricing Factors
Ice depth and thaw time
A lightly frosted coil thaws in 30 minutes. A coil encased in an inch of ice takes 90 minutes or more and can soak the drain pan, which adds cleanup time.
Refrigerant leak location
A flare fitting leak is a quick repair. A leak inside the evaporator coil may require coil replacement, which is the largest single cost factor in this service.
Failed components
Blower motors, run capacitors, and contactors are common freeze causes. A capacitor is $150 to $280 installed; a blower motor runs $350 to $650 depending on the model.
Refrigerant type
R-410A and R-32 are readily available. Legacy R-22 systems cost more per pound, and we discuss whether a recharge is worth it on an older unit.
Access and attic conditions
An air handler in a hot attic or tight closet takes longer to access and work around. We note access on the phone so the quote reflects it.
Typical Investment Range
$180 - $1,100 depending on scope
Actual pricing varies based on project scope and requirements
Value You Receive
A thaw and clean at $180 to $320 protects a compressor that costs $1,500 to $2,200 to replace. Fixing the cause now is the difference between a repair bill and a system replacement.
Frequently Asked Questions

Call UsHow much does frozen evaporator coil repair cost in Greenville SC?
Most Greenville frozen coil repairs run $180 to $320 for a thaw, clean, and airflow fix, and $450 to $1,100 when a refrigerant leak repair and recharge are needed. A failed blower motor adds $350 to $650. We quote the diagnostic fee and the repair price before we start, so you approve the number first.
Why is my AC evaporator coil frozen in Greenville?
The two causes are low airflow and low refrigerant charge. In Greenville, a clogged air filter, a weak blower motor, or an undersized return duct drops coil temperature below freezing. A slow refrigerant leak does the same. We test blower amp draw, static pressure, and refrigerant pressures to tell which one you have.
Can you fix a frozen AC coil same day in Greenville South Carolina?
Yes. Call before noon and we can usually be at your door by late afternoon. Our trucks carry R-410A, R-32, run capacitors, contactors, and blower motors, so most same day frozen coil repair Greenville SC calls finish in one visit. Thaw and clean takes two to four hours including verification.
How do I prevent my AC coil from freezing in Greenville?
Change your air filter every 60 days, keep the condensate drain line clear, and have the coil cleaned each spring before the humid season starts. We also check refrigerant pressures annually, because a slow leak shows up as a small pressure drop long before the coil ices over. Those three habits prevent most freezes.

Customer Reviews
Our AC froze solid on a Saturday in July. They thawed the coil, found a clogged filter and a weak blower motor, and had cold air back by dinner. Price matched the quote exactly.
Second company to look at our frozen coil. First one just thawed it and left. These guys found the refrigerant leak, fixed it, and recharged. No freeze since. Worth the call.
Property manager here. They handled three frozen units in one afternoon at our Haywood Road building. Clear communication, fair pricing, and they cleaned up after themselves.
