AC Refrigerant Recharge Service in Richardson, TX
A refrigerant recharge isn't just topping off a tank — a properly sealed AC system doesn't consume refrigerant, so if you're low, there's a leak somewhere. We find the leak first, then repair it, then recharge the system. Adding refrigerant without finding the leak just delays the next failure.
Richardson AC Repair Pros provides AC refrigerant recharge service for homeowners across Richardson, TX. Call for a free inspection and a written quote before any work begins.
When to Call
When You Need AC Refrigerant Recharge Service
- Your system runs constantly but never gets the house below 78 or 79 degrees.
- You can see ice forming on the refrigerant lines near the outdoor unit.
- A technician told you at your last tune-up that pressures were low.
- The system cools fine in spring but struggles badly once temps hit the 90s.
- You notice the indoor unit is blowing air but it's not noticeably cold.
- An oily residue has appeared on or near the refrigerant line connections.
How It Works
Our Process for AC Refrigerant Recharge Service
- 1
Pressure testing
We connect gauges to the service ports and read suction and discharge pressures. Low readings on a closed system confirm refrigerant loss.
- 2
Leak detection
We use an electronic leak detector and UV dye to locate the leak point. Common spots include the evaporator coil, schrader valves, and flare fittings at the lineset.
- 3
Leak repair
We repair or replace the leaking component before adding any refrigerant. Recharging without this step is something we won't do — it doesn't solve the problem.
- 4
Vacuum and charge
After the repair, we pull a vacuum to remove moisture and air from the circuit. Then we charge to manufacturer spec by weight, not by feel.
- 5
Performance verification
We check suction and discharge pressures at operating conditions and verify the temperature split across the evaporator coil before we close up.
What's included
- Pressure testing to confirm and quantify refrigerant loss.
- Electronic leak detection across the full refrigerant circuit.
- Labor to repair accessible leak points found during the visit.
- Vacuum pull after repair to clear moisture from the circuit.
- Refrigerant charge by weight to manufacturer specification.
- Post-charge pressure and temperature split verification.
What's not included
- Evaporator coil replacement if the coil is leaking and beyond repair — that's a separate job.
- Refrigerant recovery and recharge if the system uses a phased-out refrigerant type that requires special handling.
- Duct repairs or airflow corrections unrelated to the refrigerant circuit.
Real Situations
Common Scenarios in Richardson
A homeowner in West Richardson notices their electric bills spiked in June even though the thermostat setting hasn't changed.
A system running low on refrigerant works harder and longer to move the same heat, which drives up runtime and cost. We check pressures, confirm the loss, find the leak source, and repair before recharging. We also verify the coil hasn't sustained damage from running low.
A homeowner finds ice on the refrigerant line outside their house on an afternoon when it's 95 degrees.
Ice on the line in summer usually points to low refrigerant or a severely restricted airflow — sometimes both. We let the ice melt before checking pressures, look at the air filter and coil condition, then do leak detection. We don't skip steps just because one cause seems obvious.
A property manager for a small apartment complex notices two units cooling poorly at the same time after a winter of no use.
Refrigerant doesn't evaporate during winter, so poor cooling after the off-season usually means the systems were already low or there's a new leak. We treat each unit separately, confirm pressures individually, and find the source before touching the refrigerant circuit.
Richardson Context
Why this matters in Richardson
Richardson's heat puts refrigerant systems under sustained stress from late April through September. That long season of high-load operation accelerates wear on flare connections and service valve seals — two of the most common leak points. Homes built in the late 1990s often have original evaporator coils that are now in the age range where pinhole corrosion becomes a real issue.
Straight Talk
About pricing & scope
The cost of a refrigerant service depends on how much refrigerant the system needs and which refrigerant type it uses. Older systems using R-22 refrigerant cost more to service than systems using R-410A. If the leak is in a place we can't repair on-site — like inside the evaporator coil — we'll tell you and explain what the next step looks like.
