AC Repair Services › Refrigerant Recharge and Leak Repair

Refrigerant Recharge and Leak Repair in Chandler, AZ

A properly sealed AC system does not consume refrigerant over time — if the level is low, something is leaking. Simply topping off the charge without finding and fixing the leak means you will be in the same situation within months or a season. We locate the leak first, 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 temperature keeps climbing toward 80 or higher
A tech previously recharged your system and it stopped cooling again within a year
You see ice forming on the copper refrigerant line running to the outdoor unit
The air coming from your vents feels less cold than it used to
Your utility bill has jumped noticeably even though usage patterns haven't changed
You hear a hissing sound near the air handler or along the refrigerant line set

How It Works

Our Process for Refrigerant Recharge and Leak Repair

1

Pressure Testing

We connect gauges to measure system pressures before adding anything. Low suction pressure is a reliable indicator of undercharge, but we confirm before proceeding.
2

Leak Search

We use electronic leak detection and UV dye to find where refrigerant is escaping. Common locations include the evaporator coil, service valves, and line set connections.
3

Leak Repair

Depending on location, the repair may involve brazing, valve replacement, or coil replacement. We do not recharge until the leak is addressed — doing so wastes refrigerant and your money.
4

System Evacuation

Before recharging, we evacuate the system to remove moisture and air. This step is skipped by shortcuts and causes long-term compressor damage. We do not skip it.
5

Refrigerant Recharge

We charge the system to manufacturer specifications by weight or by superheat and subcooling measurements — not by rule of thumb or visual gauge readings alone.
6

Performance Verification

After recharge, we measure supply and return air temperatures and verify the system is operating within normal parameters before leaving the property.

What's included

Refrigerant pressure diagnostic before any charge is added
Electronic and dye-based leak detection on accessible components
Leak repair at the identified point — labor and standard fittings included
System evacuation before recharge to remove contaminants
Refrigerant recharge to manufacturer specifications with verification

What's not included

Evaporator coil replacement if the coil itself has failed — that is a separate quoted scope
Ductwork or air handler access if walls or ceilings must be opened — requires additional planning
Refrigerant beyond the system's specified charge — overburdened systems have their own problems

Real Situations

Common Scenarios in Chandler

A homeowner in the Fulton Ranch area had their system recharged two summers ago and it is underperforming again.

We treat this as a leak situation from the start. We search for the leak source rather than recharging again. Repeated short cycles of refrigerant loss almost always trace back to a slow evaporator coil leak or a failing service valve.

A homeowner calls in June after noticing ice on the refrigerant line outside.

We turn the system off to let it thaw before inspecting — running a frozen system risks compressor damage. Once thawed, we check refrigerant pressures and airflow, since both low charge and a clogged filter can cause icing.

A homeowner in a 2001-era home near Chandler Fashion Center has a system that's been slowly losing cooling capacity over two summers.

Slow capacity loss often points to a small evaporator coil leak that hasn't fully failed yet. We check the coil carefully with both electronic detection and dye. Early coil leaks can sometimes be sealed; others require coil replacement, which we quote separately.

Chandler Context

Why this matters in Chandler

Chandler's heat puts AC systems under continuous load from May through September, which accelerates wear on evaporator coils and service valve seals. Homes built in the late 1990s and early 2000s — a large portion of Chandler's housing stock — often have original coils that are now showing pinhole leaks. The desert air also dries out certain seals faster than humid climates, contributing to refrigerant loss at connection points.

Straight Talk

About pricing & scope

Refrigerant cost depends on the type your system uses and how much is needed. Older systems using R-22 refrigerant are more expensive to recharge than newer R-410A systems, and R-22 availability is limited. If the leak is in the evaporator coil and the coil needs replacement, that changes the scope and cost significantly — we explain that before proceeding.
