AC Refrigerant Recharge in Richardson, TX

Refrigerant recharge means restoring the refrigerant level in your AC system so it can move heat properly and cool your home again. The important thing most companies don't mention: refrigerant doesn't get used up. If it's low, there's a leak somewhere, and adding refrigerant without finding that leak is a temporary fix at best.

When to Call

When You Need AC Refrigerant Recharge

The air coming from your vents feels barely cooler than room temperature
The indoor coil or copper lines are freezing up and icing over
Your AC runs all day but the house temperature barely drops
A technician previously added refrigerant but the problem returned within a season
The outdoor unit is running but suction line feels warm instead of cold
You can hear the compressor laboring harder than usual on hot afternoons

How It Works

Our Process for AC Refrigerant Recharge

1

Pressure test before anything

We connect gauges and check both high and low side pressures. This tells us how far off the charge is and gives us the first clue about where the leak might be.
2

Leak search

We use an electronic leak detector and UV dye to find where refrigerant is escaping. Common spots include the evaporator coil, service valve fittings, and brazed joints.
3

Assess the leak and repair options

Small fitting leaks can often be repaired the same visit. Coil leaks are more involved and we'll quote that repair separately before proceeding.
4

Recharge to manufacturer spec

We add refrigerant by weight, not by feel. The system gets charged to the exact spec on the data plate — not just until the gauges look okay.
5

Verify system performance

After the recharge we check supply air temperature, delta-T across the coil, and operating pressures together to confirm the system is working correctly.

What's included

Refrigerant pressure check before and after the recharge
Electronic leak detection as part of the standard scope
Refrigerant added to bring the system to manufacturer specification
System performance verification after the charge is complete
Written record of the refrigerant type, amount added, and pressures

What's not included

Evaporator or condenser coil replacement — that is quoted separately if the coil is the leak source
UV dye injection on systems that already have dye — we note this and adjust the approach
Refrigerant recovery if the system needs to be opened for coil work — that adds to the scope

Real Situations

Common Scenarios in Richardson

A homeowner in the Heights area had refrigerant added by another company last summer and now the AC is blowing warm air again.

This is a classic sign of an unrepaired leak. We find the leak first before we add anything. Adding refrigerant to a leaking system again would just repeat the same cycle and waste money.

A homeowner notices ice on the refrigerant line outside the house and turns the system off, worried about damage.

Turning it off was the right call. We let the system thaw completely before checking pressures — reading gauges on a frozen system gives false numbers. Once thawed, we check the charge and test for leaks before recharging.

An older home in Canyon Creek has an AC system running R-22 refrigerant, which is no longer manufactured.

We tell the homeowner honestly that R-22 availability is limited and the cost reflects that. We also give them a straight assessment of whether recharging a system this age still makes financial sense versus replacing it.

Richardson Context

Why this matters in Richardson

Texas summers put refrigerant systems under sustained stress for months at a time, and small leaks that were marginal in spring become obvious failures by July. Richardson's older neighborhoods have a lot of systems that were installed in the late 1990s and early 2000s — many still running R-22 — that are reaching the point where leak repairs become a recurring cost. That's worth knowing before deciding whether to recharge or replace.

Straight Talk

About pricing & scope

Recharge cost depends on the type of refrigerant your system uses, how much it needs, and whether the leak repair is included or a separate job. Older systems running R-22 cost more to recharge than newer R-410A systems simply because the refrigerant is scarcer. We'll tell you the refrigerant type and quantity before we start so there are no surprises.
