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.
When Replacement Makes More Sense Than Repair
An evaporator coil sits in the air handler or furnace cabinet and is where refrigerant absorbs heat from the air moving through your home's ductwork, boiling from liquid to vapor as it does. It's a demanding environment for a component to live in over the long term: constant temperature cycling, condensation forming and draining off the coil surface during every cooling cycle, and depending on the system's age, years of refrigerant and oil circulating through relatively thin-walled tubing. Coils commonly fail from formicary corrosion, the pinhole-forming acid attack on copper we mentioned elsewhere, from erosion at bends and joints after many years of vibration, or from physical damage during other work in the air handler cabinet.
We recommend replacement over repair when a coil shows multiple leak points rather than one isolated failure, when the coil is old enough that further investment doesn't make financial sense relative to remaining system life, or when the coil design itself, particularly on older R-22 systems, isn't compatible with a system-wide refrigerant retrofit that might otherwise be planned. Replacement means recovering the existing refrigerant charge, disconnecting and removing the failed coil from the cabinet, which sometimes requires disassembling parts of the air handler housing depending on coil size and cabinet clearance, installing the new coil sized to match the system's tonnage and airflow requirements, then brazing the new connections, pressure testing with nitrogen, evacuating to proper micron level, and recharging by weight verified against subcooling and superheat targets.
Coil matching matters more than it might seem. Installing a coil that isn't correctly matched to the outdoor condensing unit in terms of capacity and metering device compatibility can produce a system that runs but never performs to its rated efficiency or capacity, essentially undoing the benefit of the repair. Many Georgetown homes built during the area's major growth period between 2005 and 2012 are now reaching the age where original evaporator coils are showing their first significant corrosion-related leaks, roughly matching typical coil service life expectations for that manufacturing era, which is why we're seeing more replacement requests, rather than repair requests, on systems from that specific vintage.
