Refrigerant Recharge and Leak Repair in Arlington, TX

Refrigerant doesn't get consumed — if your system is low, it leaked out somewhere. Adding refrigerant to a leaking system just delays the problem and wastes money. We find the leak first, repair it, and then charge the system to the correct level for your specific equipment.

When to Call

When You Need Refrigerant Recharge and Leak Repair

AC blows cool but not cold, and it's been getting worse over a few weeks
You can see ice forming on the refrigerant line going into the air handler
A technician told you the system was low on refrigerant last season
There's an oily residue around the outdoor unit's service valves
Your electric bill has climbed but the house still doesn't get cool
The system takes much longer to cool the house than it used to

How It Works

Our Process for Refrigerant Recharge and Leak Repair

1

Pressure check

We connect gauges and record static and operating pressures. This tells us how low the system is and gives clues about where the leak might be.
2

Leak search

We use an electronic leak detector and UV dye to locate the leak point. Common locations are evaporator coil, service valve fittings, and the line set at connection points.
3

Leak repair

Minor leaks at fittings can often be corrected on the same visit. Evaporator coil leaks are more involved and may require coil replacement, which we quote separately.
4

System evacuation

Before recharging, we pull a vacuum on the system to remove moisture and air. Skipping this step causes long-term compressor damage.
5

Recharge to spec

We charge to the manufacturer's specified superheat or subcooling target, not just to a pressure number. This matters for compressor longevity.
6

Recheck and document

We verify pressures and temperatures after charging, then document the refrigerant type, amount added, and leak location in your service record.

What's included

Electronic leak detection across the full refrigerant circuit
UV dye injection for confirming leak location where needed
Repair of accessible leak points at fittings and service valves
System evacuation prior to recharge
Refrigerant charge to manufacturer's superheat or subcooling specification
Post-charge pressure and temperature verification

What's not included

Evaporator or condenser coil replacement is a separate quoted job if the coil has failed
Refrigerant itself is a material cost added to the service charge based on type and quantity
Line set replacement, if needed due to physical damage, is quoted separately

Real Situations

Common Scenarios in Arlington

A homeowner in north Arlington notices ice on the copper line running into their house and the upstairs won't get below 78.

We let the ice thaw before pulling pressures — running gauges on a frozen system gives bad data. Once it's clear, we check static pressure, locate the leak with a detector, and give a written quote for the repair and recharge.

A rental property owner near the Entertainment District had refrigerant added by another company last summer, and now the tenant is calling again with the same problem.

We start the leak search at the evaporator coil and line set connections, which are the most likely locations on a system that keeps losing charge. If the coil is leaking, we give an honest assessment of repair cost versus equipment age.

A homeowner finds oil staining around the service valve caps on their outdoor unit.

Oil staining at the service valves usually means the Schrader cores or valve caps are leaking. These are straightforward repairs. We check pressures, replace the cores, and recharge if the system is low.

Arlington Context

Why this matters in Arlington

Arlington's heat means AC systems run hard from May through September, which accelerates wear on coil connections and line set fittings. The clay soil movement common in this part of Tarrant County can stress refrigerant lines where they enter the slab or connect at the air handler. Older neighborhoods like Dalworthington-adjacent areas and central Arlington have a high proportion of R-22 systems still in service.

Straight Talk

About pricing & scope

The cost of this service depends heavily on how much refrigerant the system needs and what type it uses. Older R-22 systems use a refrigerant that costs significantly more than the R-410A used in most equipment made after 2010. If the leak is in the evaporator coil, that becomes a parts and labor job on top of the recharge.
