Freon Leak Repair in Portland, ME
A refrigerant leak repair means locating exactly where refrigerant is escaping and sealing or replacing that component. Topping off refrigerant without fixing the leak is a short-term patch — the system will lose charge again. Leaks happen at coil joints, valve fittings, or corroded coil surfaces. Finding the exact location takes time and the right equipment, but it's the only fix that actually holds.

When to Call
When You Need Freon Leak Repair
- Your AC was recharged last summer and it's already underperforming again this season.
- You can see oily residue around the refrigerant line fittings outside your unit.
- A technician confirmed low charge but said they couldn't find where it was leaking.
- Your evaporator coil area smells faintly sweet or chemical when the system runs.
How It Works
Our Process for Freon Leak Repair
- 1
Electronic Leak Detection
We use an electronic refrigerant detector to sweep the evaporator coil, line set, and condenser coil for any trace of escaping refrigerant.
- 2
UV Dye Trace if Needed
If the electronic search is inconclusive, we introduce UV dye and run the system to make small leaks visible under UV light.
- 3
Repair or Component Swap
Depending on location, we braze the leak closed, replace a fitting, or recommend coil replacement if corrosion is widespread.
- 4
Pressure Test and Recharge
We pressure-test the repaired section, confirm it holds, then recharge the system to the correct level by weight.
Portland Context
Why this matters in Portland
Salt air from Casco Bay accelerates coil corrosion, especially on systems installed on the coastal side of homes in Portland's East End and Munjoy Hill neighborhoods. That means refrigerant leaks here often stem from coil degradation, not just fitting failures.
Straight Talk
About pricing & scope
Scope depends entirely on where the leak is and how much coil surface is affected. A pinhole at a fitting is a quick fix. Widespread formicary corrosion on an evaporator coil means the coil itself needs replacing.
