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.
Protecting Your System From Theft and Tampering
Locking refrigerant caps replace the standard plastic or brass caps found on service valve ports and Schrader valves with a tamper-resistant version that requires a special key to remove. They serve two purposes: providing a secondary seal against slow refrigerant leaks at the valve stem, and preventing unauthorized access to the refrigerant circuit, whether that's someone attempting to steal refrigerant, most often R-410A given its value and demand, or simple vandalism and tampering that can cause a system to lose its charge or suffer contamination from an improperly connected device.
Refrigerant theft has become a more recognized issue nationally as refrigerant prices have risen with phase-down regulations limiting production of certain refrigerant types, and vacant new-construction properties, common throughout Georgetown's ongoing residential growth in developing subdivisions, are a particular target since an unoccupied home with an installed but unused outdoor unit can go unnoticed for extended periods if refrigerant is stolen or the unit is tampered with. Standard caps offer essentially no resistance to anyone with basic tools, while a locking cap requires a specific key most homeowners keep separately from the unit itself, adding a meaningful deterrent even though no lock is completely theft-proof.
Installation is straightforward: we remove the existing cap, inspect the valve stem and threads for any damage or existing leak, and thread on the locking cap to proper torque specification, verifying with electronic leak detection that the cap itself creates a proper seal. We typically install locking caps on both the liquid and suction line service valves at the outdoor unit as a set, and we recommend them as standard practice on new installations and after any service call that required accessing the valves, since it's a low-cost addition that provides ongoing protection. For homeowners in developing areas or with a history of any tampering or theft concerns, we can also discuss additional physical security measures for the outdoor unit itself, cages or enclosures that further limit access, though locking caps alone address the specific refrigerant circuit vulnerability at minimal cost and effort.
