Important: Refrigerant work is EPA regulated. ProAir Georgetown technicians hold current EPA Section 608 Universal certification. We recover, recycle, and recharge refrigerant according to federal regulations and never vent refrigerants to atmosphere.
Refrigerant Leak Detection & Testing
Professional leak detection using electronic sniffers and UV dye. Find leaks before recharging, or recharge just moves the problem.
High-sensitivity electronic leak detectors locate small leaks in coils, line sets, and fittings that visual inspection misses.
UV dye injection and black light inspection, effective for finding intermittent or slow leaks that evade electronic detection.
Pressure test refrigerant circuits with dry nitrogen to verify leak-free condition before charging new refrigerant.
Refrigerant Service & Recovery
Proper refrigerant recharge, measured by subcooling and superheat, not just pressure gauges. We charge to manufacturer spec.
EPA-compliant refrigerant recovery before any system work requiring circuit opening.
Deep vacuum pull to remove moisture and non-condensables before refrigerant charge, critical for system longevity.
Extended deep vacuum to achieve proper micron levels, we don't rush this step that protects compressor life.
Convert systems from discontinued refrigerants to approved drop-in or replacement refrigerants.
Line Set Service & Repair
Flush contaminated line sets during compressor replacement to prevent new compressor failure from acid or debris.
Professional braze repair of pinhole leaks and joint failures in copper refrigerant lines.
Repair damaged liquid line sections including crimps, kinks, and corrosion failures.
Replace deteriorated suction line insulation, critical for efficiency and preventing condensation in Georgetown's humid summers.
Seal wall and foundation penetrations around line sets to prevent pest entry and air infiltration.
Install locking valve caps to prevent refrigerant theft and unauthorized access to Schrader valves.
Cooling Circuit Components
Replace leaking Schrader valve cores, a small but common source of refrigerant loss over time.
Install or replace liquid line filter driers, required after any system opening to remove moisture and acid.
Replace leaking or damaged service valves on compressors and line set connections.
Replace failed accumulators that protect compressors from liquid refrigerant slugging.
Replace failed thermostatic expansion valves, a hunting or stuck TXV causes refrigerant distribution problems and efficiency loss.
Repair or replace discharge line mufflers that reduce compressor noise and vibration.
Evaporator & Condenser Coil Service
Clean, inspect, and service evaporator coils, dirty coils are a leading cause of reduced cooling capacity in Georgetown homes.
Replace failed or leaking evaporator coils, including proper refrigerant recovery, installation, and recharge.
Straighten bent evaporator fins to restore full airflow through the coil and recover lost capacity.
Clean condenser coils fouled by Georgetown's cottonwood, dust, and debris, critical for summer efficiency.
Repair pinhole leaks and minor damage in condenser coils when full replacement isn't required.
Deep acid wash for severely fouled condenser coils, removes mineral scale, oxidation, and embedded debris.
Address the root cause of a frozen evaporator coil, low refrigerant or restricted airflow. We fix the cause, not just defrost.
Diagnose and repair the refrigerant or airflow condition causing ice formation on copper suction lines.
Repairing Rather Than Replacing a Coil
Condenser coils develop leaks from a handful of specific causes, and which one applies determines whether repair is even a reasonable option. Physical damage, a bent fin puncture from a fallen branch, a lawn tool strike, or hail impact common during Central Texas spring storms, tends to produce a localized, repairable leak at a single tube. Formicary corrosion, sometimes called ant nest corrosion, is a different and more serious problem where organic acids, often from certain wood products, adhesives, or airborne contaminants, attack the copper tubing wall from the outside and create a network of pinhole leaks that look like tiny wormholes when you cut into the tube. Formicary corrosion tends to be widespread across the coil rather than localized, which usually rules out a simple patch repair.
For a single, localized leak from physical damage, we recover the refrigerant charge, isolate the affected section, and braze a repair directly at the leak point or splice in a short section of new tubing if the damage is more extensive. After the repair we pressure test the entire circuit with dry nitrogen to confirm the fix holds and that there are no other leaks nearby that a first inspection missed, since coil damage from an impact often affects more than the one obviously bent fin. Once the pressure test holds steady, we evacuate the system to remove air and moisture and recharge to the manufacturer's specification.
Repair isn't always the right call. A coil showing multiple leak points, especially the scattered pinhole pattern typical of formicary corrosion, will very likely develop new leaks elsewhere within a season or two even after a successful repair at the current leak site, so we're upfront when replacement is the more sensible long-term choice rather than repeatedly chasing new pinholes. Coil age also factors in: a coil that's ten or more years old and already showing corrosion is a different repair decision than a two-year-old coil damaged by a single hailstorm. Hail is a real consideration in Georgetown, Williamson County sees severe spring storm systems most years, and a hail-damaged coil with bent fins across a wide area but only one active leak point is often still a good repair candidate, since the underlying metal hasn't been chemically compromised the way corrosion-driven leaks have.
