A refrigerant leak is one of the most common — and most mishandled — AC problems in Spring TX. The system keeps running, so many homeowners don't realize there's a problem until the electric bill spikes, the house won't cool, or ice appears on the copper line. Here's how to recognize it and what a proper repair involves.

System runs constantly but house cools slower than it used to. Air from vents feels cool but not cold. Electric bill higher than normal. Ice on the copper refrigerant line near the indoor unit. Hissing or bubbling sound from refrigerant lines. System that used to handle 100°F days now struggles at 90°F.
💰 Cost: Schedule diagnosis if you notice these signs
Small leaks develop over time from: vibration loosening Schrader valve cores, erosion of copper tubing from formicary corrosion (caused by formic acid in some building materials), improper installation creating stress points, and age-related fatigue at coil connections. Refrigerant doesn't deplete — if it's low, there's a leak.
💰 Cost: All leaks must be found and repaired — not just recharged
Some companies will charge refrigerant and leave without finding the leak. This is: a temporary fix that will fail again in months, a waste of your money, and technically non-compliant with EPA regulations that require leak repair for systems over 50 lbs of refrigerant. Always ask: 'Where is the leak?'
💰 Cost: Insist on leak detection before refrigerant is added
Step 1: Electronic leak detection to locate the exact leak point. Step 2: Recover remaining refrigerant. Step 3: Repair or replace the leaking component. Step 4: Pressure test to confirm repair. Step 5: Recharge to proper specification. Step 6: Verify system performance.
💰 Cost: $200–$600 for complete leak repair + recharge
Leaks in the evaporator coil are the most expensive to repair. Coil replacement runs $800–$1,800 installed. On a system 10+ years old, a leaking evaporator coil often tips the scales toward full replacement.
💰 Cost: Coil replacement: $800–$1,800. Compare to new system.
Signs include: system running constantly but not cooling well, air from vents feeling only slightly cool, electric bills higher than normal, ice forming on the copper refrigerant line or indoor unit, and hissing or bubbling sounds near refrigerant lines. In Texas, these symptoms often appear gradually over one or two summers before becoming obvious.
A complete refrigerant leak repair in Spring TX typically costs $200–$600, including leak detection, repair of the leak point, and refrigerant recharge. If the leak is in the evaporator coil requiring coil replacement, costs rise to $800–$1,800. Get a diagnosis before approving any refrigerant work.
No — refrigerant handling is regulated by the EPA and requires a Section 608 certified technician. More importantly, adding refrigerant without finding and fixing the leak is a temporary fix that will fail again. The leak must be found and repaired first.
A straightforward refrigerant leak repair typically takes 2–4 hours for locate, repair, and recharge. Complex leaks — especially evaporator coil leaks — may require ordering parts and take 1–2 days. Same-day service is available in many cases at AC Repair Expo.
