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.
The Small Part That Protects Your Whole System
A liquid line filter drier is installed on the liquid line between the condenser and the metering device, and it does two jobs at once: it filters out solid particulate, debris, metal shavings, or braze slag left over from installation or repair work, and it contains a desiccant material that absorbs moisture from the refrigerant. Both functions matter because either contaminant, left uncaptured, causes real damage downstream. Solid debris can clog or erode the metering device, whether that's a TXV orifice or a fixed restrictor, while moisture reacts with refrigerant and oil to form corrosive acids that attack metal surfaces and can also freeze at the metering device, causing intermittent restriction.
Filter driers aren't installed once and forgotten. They have a finite moisture and acid absorption capacity, and once that capacity is used up, the desiccant can no longer protect the system, or worse, can begin releasing what it's absorbed back into the refrigerant stream under certain conditions. We install or replace a filter drier any time a refrigerant circuit is opened for repair, whether that's a coil replacement, compressor swap, or line set repair, since any point where the system is opened introduces some amount of air and moisture regardless of how careful the evacuation afterward is. After a compressor burnout specifically, we use a higher-capacity burnout-rated drier designed to absorb the additional acid contamination that comes with that type of failure, and we typically plan to check or replace it again after a short run-in period once the worst of the contamination has been captured.
Sizing matters more than it might seem. A drier that's too small for the system's refrigerant flow rate creates a pressure drop across it, which shows up as reduced subcooling and can mimic a low charge symptom even though the actual refrigerant amount is correct. We size the drier to the system's tonnage and refrigerant type, and we always braze it in with the flow direction arrow correctly oriented, since installing it backward defeats its filtering function entirely. Once installed, we always check for a temperature drop across the drier during operation, a properly functioning drier with adequate capacity should show minimal temperature difference between its inlet and outlet, while a significant drop indicates it's already restricted or undersized for the application.
