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 Damage Along the Liquid Line
The liquid line carries high-pressure, subcooled liquid refrigerant from the condenser coil to the metering device at the evaporator coil. Because it operates at high pressure and typically runs a smaller diameter than the suction line, damage here tends to produce a more noticeable, faster refrigerant loss than a comparable issue on the low-pressure side. Common causes of liquid line damage we see around Georgetown include a nail or screw driven through the line during other home renovation or hanging work, a kink or crimp from improper support or from being bent too sharply during original installation, and corrosion at a joint or fitting exposed to moisture over years.
Foundation movement is a factor specific to this region worth mentioning. Williamson County sits on expansive clay soils in many areas, soil that swells when wet and shrinks when dry through the normal cycle of Central Texas seasons, and that movement can shift slab foundations enough over years to stress rigid copper lines that pass through or near foundation penetrations without adequate flexibility built into the routing. A line set installed too rigidly at a foundation penetration, without a service loop or flexible section to absorb minor foundation movement, is more prone to developing a stress crack or joint failure over time than one installed with that movement anticipated.
Repair approach depends on the type and location of damage. A clean puncture or small crack can often be repaired with a braze patch directly at the damage point after cutting back to sound tubing on either side. A crimped or kinked section usually needs to be cut out and replaced with a new section of properly sized copper tubing, since a kink permanently restricts flow even if it's not currently leaking, and it will typically fail eventually from the stress concentration at the bend. Corroded fittings are generally best replaced entirely rather than patched, since visible corrosion at one point often indicates the surrounding metal has also been weakened. After any liquid line repair, we pressure test with dry nitrogen, evacuate to proper micron level, and recharge to manufacturer specification, verifying subcooling at the liquid line to confirm the repair hasn't introduced any new restriction.
