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.
Keeping Your Evaporator Coil Clean
The evaporator coil is where the cooling actually happens inside your home, absorbing heat from the air that flows across it before that air is pushed through your ductwork. Because it operates cold and wet, condensation forms on its surface during nearly every cooling cycle, and that moist environment is ideal for dust, pet dander, and airborne particles to stick and accumulate on the fin surface over time. A layer of buildup on the coil acts as insulation, reducing how effectively the coil can transfer heat from the passing air, and it also restricts airflow the same way dirt does on a filter, both effects working together to reduce cooling capacity and system efficiency.
Georgetown's cedar fever season each winter, when juniper pollen blankets the area, along with a long allergy season overall from oak and grass pollens common to Central Texas, means homes here often pull more airborne particulate through their return air system than homes in regions with shorter or milder pollen seasons. Combined with normal household dust and pet hair, that adds up to coil buildup that develops faster than many homeowners expect, particularly if air filters aren't changed on a regular schedule, since a coil is essentially a secondary filter catching whatever gets past the primary one.
Service involves inspecting the coil visually with a mirror and flashlight or by pulling an access panel, checking both fin condition and buildup level, then cleaning with a coil-safe foaming or no-rinse cleaner formulated for evaporator coils specifically, since some cleaners designed for outdoor condenser coils aren't appropriate for the tighter, less-ventilated space of an evaporator cabinet. We also check the condensate drain pan and drain line during coil service, since a coil producing normal condensation needs that water to actually leave the system, and a clogged drain combined with coil buildup compounds moisture problems in the cabinet. After cleaning, we verify airflow has improved and check operating temperatures and pressures to confirm the coil is performing correctly, since a visibly cleaner coil doesn't always mean full performance has been restored if there's also a fin damage or airflow issue elsewhere in the system.
