AC Refrigerant Recharge Service in Plano, TX
Refrigerant is the substance your AC uses to move heat out of your home. When the level drops, the system loses its ability to cool no matter how long it runs. Low refrigerant is always the result of a leak — refrigerant doesn't get used up the way fuel does — so a recharge without finding the leak is a temporary fix at best.
Plano AC Repair Pros provides AC refrigerant recharge service for homeowners across Plano, 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 AC runs constantly but the house never drops below 78 or 79 degrees
- Ice is forming on the copper lines or the indoor coil
- You notice a hissing or bubbling sound near the outdoor unit
- The air coming from vents feels mildly cool rather than cold
- A previous technician said refrigerant was low but didn't find the leak
- Your system is older and efficiency has dropped noticeably over one season
How It Works
Our Process for AC Refrigerant Recharge Service
- 1
Symptom Review
We ask how long the issue has been developing and whether anyone has added refrigerant before. Prior charges without leak repair tell us a lot about what to expect.
- 2
Pressure Testing
We connect gauges to both the high and low side of the system. Pressure readings tell us how far off the charge is and whether the compressor is functioning.
- 3
Leak Search
We use an electronic leak detector and UV dye to locate the source. Common spots are the evaporator coil, schrader valves, and line set connections.
- 4
Leak Assessment
We tell you where the leak is, how bad it is, and what fixing it requires. Some leaks are minor and repairable on the spot. Others mean a coil replacement.
- 5
Refrigerant Addition
Once the leak situation is addressed or a plan is in place, we recharge the system to manufacturer specification. We don't estimate — we measure by weight.
- 6
Performance Confirmation
We measure the temperature split between supply and return air. A properly charged system should show a specific delta that confirms correct operation.
What's included
- High and low side pressure testing with calibrated gauges
- Electronic leak detection across all accessible refrigerant circuit components
- Refrigerant added to bring the system to correct operating charge
- Temperature differential check after charge to confirm system performance
- Documentation of refrigerant type, amount added, and leak location if found
What's not included
- Coil replacement or line set repair if the leak source requires it — quoted separately
- Refrigerant recovery if the system needs to be evacuated for a repair first
- Ductwork inspection, which is a separate service if airflow is also a concern
Real Situations
Common Scenarios in Plano
A homeowner in Plano's Willow Bend area calls because their upstairs system freezes up every afternoon and then blows warm air.
Freeze-thaw cycles like this are a classic sign of low refrigerant. We let the system thaw completely before testing — gauging a frozen system gives bad data. Once clear, we test pressure, find the leak location, and walk through repair options before adding any refrigerant.
A homeowner off Parker Road had refrigerant added last summer but is having the same cooling problem again this year.
Repeat low charges mean the leak was never fixed. We focus on finding that leak first. If it's a slow evaporator coil leak, we'll discuss whether repair or replacement makes more sense given the system's age.
A new homeowner in East Plano discovers after move-in that the system uses R-22, which is no longer manufactured.
We explain the R-22 situation plainly — it's available but expensive and increasingly scarce. We test for leaks, give you an honest picture of the system's condition, and let you decide between recharging with reclaimed refrigerant or planning a system replacement.
Plano Context
Why this matters in Plano
Plano's clay-heavy soil shifts significantly with the wet-dry cycles we get here. That movement stresses refrigerant line connections over time, particularly where lines pass through walls or transition from underground to above-grade runs. Homes built in the early 2000s in subdivisions like Ridgewood or Deerfield often show this kind of slow connection leak by the time systems hit 12 to 15 years old.
Straight Talk
About pricing & scope
The cost of this service depends heavily on how much refrigerant the system needs and what type it uses. R-410A and R-22 are priced very differently. If a leak repair is also needed, that adds to the scope. We tell you what we find before we proceed — you won't get a bill for work you didn't approve.
