AC Repair Services › Refrigerant Recharge and Leak Repair

Refrigerant Recharge and Leak Repair in Plano, TX

Refrigerant doesn't get used up the way fuel does. If the level is low, the system has a leak somewhere. Adding refrigerant without finding and fixing the leak is a temporary fix that puts you back in the same situation within months. We locate the leak, repair it, and then recharge to the correct level for your specific equipment.

When to Call

When You Need Refrigerant Recharge and Leak Repair

Your AC blows air but the house won't reach the set temperature.
The indoor evaporator coil is freezing up repeatedly.
You can see ice on the refrigerant lines running to the outdoor unit.
A technician previously added refrigerant and now it's low again.
Your system is cooling unevenly and the refrigerant lines feel warm.
The outdoor unit runs but the air coming from vents is barely cool.

How It Works

Our Process for Refrigerant Recharge and Leak Repair

1

Pressure test and measurement

We connect gauges to check the actual refrigerant pressure against the spec for your unit's refrigerant type. This confirms whether low charge is the real problem.
2

Leak search

We use an electronic leak detector to check the evaporator coil, line set connections, Schrader valves, and the condenser coil. Leaks are often small and not visible to the eye.
3

Confirm leak location

Once the detector indicates a zone, we verify with dye or further testing. We don't guess at a location and recharge hoping for the best.
4

Repair the leak

Most leaks at fittings and valve cores can be fixed on the same visit. Evaporator coil leaks may require a coil replacement if the coil itself has corroded through.
5

Recharge to spec

After the leak is repaired, we add the correct refrigerant type to the manufacturer's specified charge weight or superheat and subcooling targets, not just until pressures look acceptable.
6

Performance verification

We run the system and measure supply air temperature to confirm it's cooling correctly before we leave. Pressures and temperatures get logged.

What's included

Full pressure test to confirm refrigerant charge status.
Electronic leak detection across all major system components.
Repair of the identified leak point.
Refrigerant recharge to manufacturer specification for your unit.
Post-recharge operational check with temperature measurement.

What's not included

Evaporator coil replacement if the coil itself is the source of the leak — that is a separate parts and labor cost.
Refrigerant cost is separate from labor — the amount needed depends on how low the system is.
We do not recharge a system without finding and repairing the leak first.

Real Situations

Common Scenarios in Plano

A homeowner in north Plano has had refrigerant added twice in three years and the AC is underperforming again.

The repeat low charge tells us there's a slow leak that has never been located. We do a full leak search rather than just topping it off again. Finding a pinhole at a coil fitting or a degraded valve core is common in this pattern.

A homeowner notices ice buildup on the copper lines outside their Plano home during a hot afternoon.

We turn the system off to let it thaw before running diagnostics, because accurate pressure readings require the coil to be clear. Once thawed, we check refrigerant charge and airflow together, since both can cause freeze-up.

Plano Context

Why this matters in Plano

Plano's heat puts refrigerant systems under sustained stress for months at a time. Older R-22 systems are increasingly common in homes built before 2010, and that refrigerant type has limited availability. Homes built on expansive clay soil here also experience foundation movement that can stress line set connections over time, creating slow leaks at joints that wouldn't exist in more stable ground.

Straight Talk

About pricing & scope

The total cost depends on how much refrigerant the system needs and where the leak is located. A valve core leak at an accessible fitting is a short repair. A leak inside the evaporator coil buried in the air handler takes more labor and may require a coil replacement. We tell you what we find before any repair decision is made.
