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.
Why Line Sets Need Flushing After a Compressor Failure
When a compressor burns out, it doesn't fail cleanly. A motor winding burnout releases acid, carbon, and metallic debris into the refrigerant and oil circulating throughout the entire system, and that contamination doesn't stay contained to the compressor shell. It travels through the discharge line, into the condenser coil, through the line set, into the evaporator coil, and back. Installing a brand new compressor into a system with contaminated line sets is one of the most reliable ways to cause that new compressor to fail again within months, since it's immediately exposed to the same acid and debris that killed the original one.
Flushing addresses this by circulating a specialized flushing solvent, or in some cases using the existing refrigerant itself under controlled conditions, through the line set and coils to physically carry contamination out of the system before the new compressor goes in. We disconnect the compressor and flush the discharge line, the condenser coil, the liquid line, and the suction line separately, since debris tends to settle differently in each section depending on flow direction and gravity. A liquid line filter drier with a higher acid-absorption capacity, often called a burnout drier, is also installed as a standard part of the process to catch any remaining trace contamination that flushing alone doesn't remove, and it's typically swapped again after a short run-in period.
Older homes in and around downtown Georgetown, along with other established neighborhoods with systems now fifteen to twenty-five years old, are where we most often perform full line set flushing, since these systems are reaching an age where compressor failure becomes more common and the original line sets have years of accumulated oil and refrigerant history in them. We test the flushed lines afterward by checking for restriction and confirming the solvent has been fully evacuated during the vacuum process, since any residual flushing agent left in the system will react with the new refrigerant charge. Skipping this step to save time is a common shortcut in the industry, and it's the single most common reason we see a replacement compressor fail again shortly after a rushed repair elsewhere.
