Coil Leak Confirmation
We use electronic leak detection and pressure testing to confirm the evaporator coil is the leak source, rather than a valve, line set joint or outdoor coil elsewhere.

Evaporator Coil Replacement in Roswell, GA
The evaporator coil sits above or inside your furnace or air handler, where it absorbs heat and moisture from the air passing over it. Over time, formicary corrosion can create tiny pinhole leaks, and coils in older systems may simply wear out. Common signs include repeated low refrigerant, ice forming on the coil, reduced cooling and water problems at the indoor unit. When repairs are no longer practical, evaporator coil replacement in Roswell restores cooling without replacing the entire system. We verify the leak location first, then help you decide whether a new coil, or a broader system upgrade, makes better sense based on the age of the outdoor unit and the refrigerant it uses. Correct coil matching is essential, because a mismatched coil can reduce efficiency, cause comfort problems and shorten compressor life.

Evaporator Coil Replacement Services in Roswell
Matched Coil Selection
The replacement coil must match the outdoor unit's capacity and refrigerant and fit the furnace cabinet. We select a compatible coil and metering device for correct performance and efficiency.
Cased and Uncased Coils
Whether your system uses a cased coil above the furnace or an uncased coil inside the air handler, we handle the sheet metal adjustments needed for a sealed fit.
Brazing and Drier
We braze the new coil to the line set with nitrogen flowing, replace the filter drier and pressure test the connections to make sure the system is tight.
Drain Pan and Line
A new coil is the right moment to address the drain pan, trap and condensate line. We confirm proper slope and drainage to prevent leaks into ceilings or closets.
Evacuation and Charge
We pull a deep vacuum, confirm it holds, then charge by weight and fine-tune with superheat or subcooling readings to match the new coil and metering device.
Why Choose our Evaporator Coil Replacement Experts in Roswell
An evaporator coil replacement involves refrigerant, brazing, sheet metal and drainage all at once, and each step affects how well the system works afterward. Our technicians approach the job carefully, confirming the leak, choosing a properly matched coil and following correct evacuation and charging procedures. That attention keeps your system efficient and protects the compressor that is already in place.
Honest guidance is part of the work. If your outdoor unit is old or uses R-22, spending money on a new coil may not be the best decision, and we will explain why. If the condenser has plenty of life left, a coil replacement can be very cost-effective. Homeowners throughout Roswell and nearby Sandy Springs rely on us for clear options, clean installations and careful workmanship.

FAQ
Evaporator Coil Replacement FAQs
Answers to the questions Roswell customers ask us most. Still unsure? Call (770) 661-0066.
What are signs of a leaking evaporator coil?
The most common sign is needing refrigerant repeatedly, along with weaker cooling, ice on the indoor coil or suction line and longer run times. You might also hear a faint hiss near the indoor unit. Because leaks can occur in several places, a technician must test the coil directly to confirm it is the source.
Can an evaporator coil be repaired instead of replaced?
Sometimes. A single accessible leak, such as at a joint or the coil's connection to the line set, can occasionally be brazed. Leaks from widespread pinhole corrosion inside the tubing are rarely worth repairing because new leaks tend to develop nearby. We explain which situation you have before recommending repair or replacement.
How long does evaporator coil replacement take?
Most replacements take most of a day once the coil is on site. The work includes recovering refrigerant, removing the old coil, fitting the new one, brazing, pressure testing, evacuation and charging. Coils sometimes need to be ordered to match your system, so the total timeline depends on part availability as well.
What affects the cost of a new evaporator coil?
Cost depends on the coil size and type, whether it is cased or uncased, the refrigerant your system uses, the metering device required and how easy the indoor unit is to reach. Attic installations take more labor than garage closets. After confirming the leak, we provide an upfront quote and discuss whether a broader upgrade makes sense.
Should I replace the whole system instead of just the coil?
If the outdoor unit is relatively new and in good condition, replacing only the coil is often a sensible investment. If the system is older, uses R-22 or the condenser is also showing wear, putting money toward a full replacement may serve you better over time. We help you compare both options honestly.
