Refrigerant Recharge and Leak Repair in Frisco, TX

Refrigerant does not get used up the way fuel does — if your system is low, refrigerant escaped somewhere through a leak. Adding more without finding and fixing that leak means the charge will drop again. We locate the leak, repair it, and then recharge the system to the manufacturer's specified level.

When to Call

When You Need Refrigerant Recharge and Leak Repair

Your system blows air but it never feels truly cold anymore
The indoor coil or suction line is freezing over regularly
Your energy bills went up but system usage seems the same
A technician told you refrigerant was low but did not find the leak
You hear a faint hissing near the refrigerant lines or coil
The system runs long cycles but struggles to reach the set temperature

How It Works

Our Process for Refrigerant Recharge and Leak Repair

1

Pressure testing

We connect gauges to the service ports and check both high and low side pressures. This tells us how low the charge is and gives the first clue about leak location.
2

Leak detection

We use an electronic leak detector and UV dye to locate where refrigerant is escaping. Common spots are the evaporator coil, Schrader valves, and brazed line connections.
3

Leak repair

Depending on the location, we repair the leak by re-brazing a joint, replacing a valve, or addressing the failed coil. We do not recharge a system with a known unrepaired leak.
4

Evacuation

We pull a vacuum on the system to remove moisture and non-condensables before adding refrigerant. Skipping this step causes long-term compressor damage.
5

Recharge to spec

We add the correct type and amount of refrigerant by weight, not by feel. We verify superheat and subcooling numbers match the manufacturer's specifications.
6

Operational verification

We run the system and confirm temperatures, pressures, and airflow are all within range before closing out the job.

What's included

Pressure testing on both high and low sides of the refrigerant circuit
Electronic leak detection to locate the source of refrigerant loss
Leak repair at the identified failure point before recharging
System evacuation to proper vacuum depth before refrigerant is added
Refrigerant recharge to manufacturer-specified weight and pressure
Post-charge performance verification including temperature differential check

What's not included

Evaporator coil replacement if the coil itself has failed beyond repair
Refrigerant line set replacement if lines are corroded or improperly routed
Air handler repairs not directly related to the refrigerant circuit

Real Situations

Common Scenarios in Frisco

A homeowner in a Frisco subdivision has had refrigerant added twice in two years by different companies, and it keeps running low again.

We do not add refrigerant until we find and fix the leak. We use dye and an electronic detector to locate the exact source. If a previous technician skipped this step, we find what they missed.

A homeowner notices their indoor coil is completely frozen and shuts the system off to let it thaw.

After the coil thaws, we test pressures to confirm low refrigerant is the cause. If a leak is present, we find it and repair it before recharging. Frozen coils from refrigerant loss are a clear diagnostic indicator.

A newer home near Fields has a system under five years old that is already showing low charge, which surprises the homeowner.

Newer systems should not lose refrigerant. We look carefully at the factory joints, the coil connections, and the line set fittings for manufacturing defects or installation errors. We document the leak location for any potential warranty consideration.

Frisco Context

Why this matters in Frisco

Frisco's heat means residential AC systems run more hours per year than equipment ratings assume. That continuous operation puts stress on brazed joints and coil fins, which are common leak points in homes here. Systems installed in the rapid-build years of the early 2000s also show age-related coil failures at higher rates now.

Straight Talk

About pricing & scope

The cost of a refrigerant service depends on where the leak is, how accessible it is, and how much refrigerant the system requires. Evaporator coil leaks are more labor-intensive to access than outdoor unit leaks. If the leak is in a location that makes repair impractical, we will tell you that honestly and explain the alternatives.
