Refrigerant Recharge and Leak Repair in Sioux Falls, SD

Refrigerant does not get used up the way fuel does — if your system is low, it leaked out somewhere. Adding refrigerant without finding and fixing that leak just delays the same problem and wastes money. We locate the leak, repair it, and then recharge the system to the correct level.

When to Call

When You Need Refrigerant Recharge and Leak Repair

Your AC runs all day but the house stays warmer than the thermostat setting
Ice is forming on the refrigerant lines or on the outdoor unit
A technician previously added refrigerant and now the system is low again
You notice a hissing or bubbling sound near the refrigerant lines or outdoor unit
Airflow seems fine but the air coming out is not cold enough
Your system short-cycles and a prior inspection noted low refrigerant pressure

How It Works

Our Process for Refrigerant Recharge and Leak Repair

1

Pressure Test

We connect gauges and check system pressure. Low pressure confirms refrigerant loss. This also helps us understand roughly how severe the leak is before we start searching.
2

Leak Detection

We use electronic leak detectors and UV dye to locate the leak. Common locations are coil connections, service valves, and the evaporator coil itself.
3

Repair the Leak

We repair the leak at the source. This might be tightening a fitting, replacing a valve, or brazing a coil joint. We do not skip this step.
4

Pressure Test After Repair

After the repair, we pressure test the system again before adding any refrigerant. This confirms the leak is sealed and not just slowed down.
5

Recharge to Specification

We add refrigerant to the manufacturer's specified charge level for your system. Overcharging causes its own problems, so we go by the spec, not by feel.
6

System Performance Check

We run the system and verify supply air temperature and system pressures are in the correct operating range before we leave.

What's included

Full refrigerant pressure test to confirm and measure the deficiency
Electronic leak detection across coils, line sets, and service connections
Leak repair at the identified source before any refrigerant is added
Refrigerant recharge to manufacturer specification for your system
Post-recharge system run to verify correct operating pressures and temperatures

What's not included

Evaporator coil replacement if the coil is too corroded to repair — quoted separately
Duct repairs or airflow corrections unrelated to the refrigerant issue
Repeat recharge visits if a second leak exists that was not detectable at time of repair

Real Situations

Common Scenarios in Sioux Falls

A homeowner in a 1990s ranch home in northwest Sioux Falls had refrigerant added twice in three years and the system is underperforming again.

This is almost certainly a slow leak that was never repaired. We do a full leak search, find the source, repair it properly, and recharge. Just adding refrigerant again would be a disservice.

A homeowner noticed ice building up on the copper line going into their outdoor unit during a hot week in July.

Ice on the lines is a classic sign of low refrigerant causing the evaporator to drop below freezing. We let the system thaw, then diagnose. We find the leak before recharging so the problem does not repeat.

A property manager for a rental near the Empire Mall area wants to stop paying for refrigerant top-offs every summer.

We do a proper leak search and repair rather than another band-aid recharge. That stops the cycle of annual service calls for the same system on the same issue.

Sioux Falls Context

Why this matters in Sioux Falls

South Dakota temperature swings put stress on refrigerant connections and coil joints over time. In Sioux Falls, a lot of homes have systems that have been running for 15 or more years through extreme cold and heavy summer use. Coil corrosion and connection failures are genuinely common here, not just something contractors say to sell work.

Straight Talk

About pricing & scope

The cost of this service depends on where the leak is, how accessible it is, and how much refrigerant the system requires. Older systems use refrigerant types that are harder to source. If the leak is in a coil that has corroded through, repair may not be practical and replacement becomes the honest conversation.
