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.
Routine Coil Care and Why It Matters
The condenser coil is the outdoor half of your refrigerant circuit, responsible for rejecting the heat your indoor coil absorbed from the house. It works by pushing outdoor air across finned copper tubing carrying hot, high-pressure refrigerant gas, condensing it back into a liquid before it heads to the metering device. That heat rejection only works efficiently when air can move freely through the fins. Even a thin, even layer of dirt across the coil face measurably raises head pressure and discharge temperature, forcing the compressor to work harder to move the same amount of heat, which shows up as reduced cooling capacity and higher electricity use long before the system fails outright.
Georgetown's spring season brings heavy oak and cottonwood debris, along with general dust from ongoing residential construction throughout Williamson County subdivisions, and all of it settles on outdoor coils positioned at ground level near landscaping. Grass clippings from mowing close to the unit are another frequent contributor we see on service calls. Left unaddressed for a full season or more, that buildup compacts against the fins and becomes much harder to remove with a simple rinse, which is part of why we recommend coil cleaning as a standing item during routine seasonal maintenance rather than only after cooling performance has already noticeably dropped.
Our service process starts with a visual inspection of fin condition, checking for bent fins that restrict airflow independent of dirt buildup, along with an inspection of the coil for any early signs of corrosion or oil residue that would indicate a developing leak. We then clean the coil with a coil-safe cleaner and low-pressure rinse, working from the inside of the coil outward relative to normal airflow direction so debris is flushed out rather than pushed further into the fin pack. For fins that have been bent from debris impact or contact during landscaping work, we use a fin comb to straighten them back into alignment, restoring the airflow path between fins. After cleaning, we check operating pressures and subcooling to confirm the coil is transferring heat correctly, since a clean coil with unresolved airflow restriction elsewhere or bent fins can still underperform even after service.
