AC Refrigerant Recharge Service in Lewisville, TX
A refrigerant recharge is not just topping off a low system. A properly closed refrigerant circuit does not lose charge on its own — if the level is low, there is a leak somewhere. Recharging without finding the leak means the refrigerant will escape again, often within the same season.
Lewisville AC Repair Pros provides AC refrigerant recharge service for homeowners across Lewisville, 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 blows slightly cool air but cannot reach the set temperature on hot days
- A technician told you last summer the system was low and it is low again
- You see oil staining near the copper line connections at the outdoor unit
- The evaporator coil keeps freezing even after you replaced the filter
- Your electric bill has jumped and the system runs much longer than it used to
- You heard a hissing sound near the indoor or outdoor unit recently
How It Works
Our Process for AC Refrigerant Recharge Service
- 1
Pressure and Temperature Check
We attach gauges to the service ports and record suction and discharge pressures. We also measure supply air temperature. These numbers tell us how far the charge is off.
- 2
Leak Search
We use an electronic leak detector to check the evaporator coil, service valves, Schrader cores, and line connections. We do not skip this step and add refrigerant without looking for the source.
- 3
Leak Repair or Documentation
If the leak is accessible and repairable on this visit, we fix it first. If it is inside the coil or in a difficult location, we document the finding and give you repair options before proceeding.
- 4
Refrigerant Addition
We add refrigerant by weight, not by feel. The correct charge depends on line length, indoor temperature, and manufacturer specs. We do not overfill.
- 5
Performance Confirmation
After charging, we run the system and verify suction pressure, superheat or subcooling, and supply air temperature fall in the correct range for current conditions.
- 6
Summary and Next Steps
We explain what we found, where the leak was, how much refrigerant was added, and what to watch for. If the leak repair is complex, we outline the options clearly.
What's included
- Refrigerant pressure and temperature diagnostic before any refrigerant is added
- Electronic leak detection check at all accessible connection points
- Refrigerant addition measured by weight to manufacturer specifications
- Post-charge system performance verification including supply air temperature
- Written summary of refrigerant added and leak findings
What's not included
- Evaporator coil replacement if the coil itself is leaking — that is a separate repair with its own scope and cost
- Duct repairs or air handler work discovered during the inspection
- Refrigerant recovery if the system needs to be evacuated for a coil or component repair — that is billed as part of that repair
Real Situations
Common Scenarios in Lewisville
A homeowner in Southridge Estates notices their upstairs zone is not keeping up in August and calls after a neighbor mentioned their system was recharged last year.
We check the charge and find it low again. We run a leak search and locate a pinhole at the evaporator coil. We explain the options — coil replacement versus continued recharging — and let the homeowner decide with full information.
A landlord managing a rental near Vista Ridge Mall gets a tenant complaint that the AC barely cools and wants it fixed quickly.
We verify the system is low on charge, locate a leaking Schrader valve core — a minor but common leak point — repair it on the spot, and recharge to spec. The tenant has working AC the same day.
A homeowner near Hebron Parkway has a newer system under manufacturer warranty and wants to know if recharging will void it.
We document everything we do, including refrigerant type, amount added, and leak location. We advise the homeowner to check their warranty terms, since a leak repair on a newer system may qualify for coverage. We do not make warranty claims ourselves.
Lewisville Context
Why this matters in Lewisville
Lewisville's clay soil shifts seasonally, and that movement stresses refrigerant line connections at the slab penetration and at the outdoor unit pad over time. It is a common and underappreciated source of slow leaks in homes built in the 1990s and early 2000s. The region's long cooling season — often running from April through October — also means leaks that start small get noticed fast because the system runs almost every day.
Straight Talk
About pricing & scope
The cost of a refrigerant recharge depends on the refrigerant type in your system and how much needs to be added. Older systems using R-22 cost significantly more to recharge than newer R-410A systems because R-22 is no longer manufactured. If a coil replacement or major leak repair is needed first, that changes the total scope. We confirm all of this before adding anything.
