AC Refrigerant Recharge in Sioux Falls, SD
Refrigerant is the fluid that moves heat out of your house — without the right amount, your AC runs but doesn't cool. A recharge means we add refrigerant to bring the system back to the correct pressure and charge level. It's not a maintenance item you do on a schedule; low refrigerant means something is wrong, and we'll tell you what.
Sioux Falls AC Repair Pros provides AC refrigerant recharge for homeowners across Sioux Falls, SD. Call for a free inspection and a written quote before any work begins.
When to Call
When You Need AC Refrigerant Recharge
- The AC runs constantly but the house stays warm even on mild days
- Ice is forming on the refrigerant lines or the indoor coil
- A technician previously told you the charge was low but you didn't get it fixed
- Your system was recently repaired and cooling performance still isn't right
- The air coming from vents is barely cooler than room temperature
- You notice the outdoor unit running but the indoor unit barely blows air
How It Works
Our Process for AC Refrigerant Recharge
- 1
Initial call and symptom check
When you call (605) 231-9370, we ask what the system is doing — or not doing. That helps us bring the right equipment and sets realistic expectations before we arrive.
- 2
Pressure testing before we add anything
We connect gauges to the system and read actual pressures. We don't add refrigerant without knowing the current state — adding to an already-charged system causes damage.
- 3
Leak check
Low refrigerant almost always means a leak. We use an electronic detector and UV dye to find where it's escaping. We won't skip this step just to do a faster job.
- 4
Leak repair decision
If we find a leak, we stop and explain your options. A recharge without fixing the leak is a short-term answer that costs you money again in a season or two.
- 5
Recharge to specification
Once we know the system is sealed — or you've decided to proceed understanding the situation — we add refrigerant to the manufacturer's specified charge by weight, not guesswork.
- 6
Performance verification
We run the system and measure supply air temperature, suction line temperature, and subcooling or superheat. Numbers confirm it's working right, not just our gut feeling.
What's included
- Gauge manifold connection and current pressure reading before any refrigerant is added
- Electronic leak detection check on accessible components
- Refrigerant added to manufacturer specification — measured by weight
- Post-charge performance verification with temperature and pressure readings
- Explanation of findings including whether a leak was identified and where
What's not included
- Leak repair itself — if a leak is found, that's quoted separately as its own job
- Refrigerant recovery from an overcharged system is billed separately from a standard recharge
- Duct-related issues that affect cooling performance are not part of a refrigerant recharge visit
Real Situations
Common Scenarios in Sioux Falls
A homeowner in the Harrisburg area notices the upstairs stays warm all summer even with the AC running full time, and a neighbor mentioned it might be low on Freon.
We start with pressures — not by just adding refrigerant because a neighbor suggested it. If the charge is low, we find the leak first. Upstairs cooling problems can also be airflow issues, so we rule that out too.
An older home near Yankton Trail has a system that was recharged by a different company last summer and is already warm again this June.
A system that loses charge two seasons in a row has a leak that wasn't found or wasn't fixed. We do a thorough leak search, not just a top-off. We tell the homeowner plainly what was missed and what it will take to actually fix it.
A homeowner calls in late July after the AC freezes up overnight and the installer said to just let it thaw and call someone.
Freezing usually means low charge or airflow restriction. We wait for the coil to thaw fully, then run our pressure checks and airflow measurements. We don't charge the system while ice is still present — it gives false readings.
Sioux Falls Context
Why this matters in Sioux Falls
Sioux Falls summers can run hot and humid for weeks at a stretch, and AC systems that were marginal in spring will fail visibly by July. A lot of homes built in the 1990s and early 2000s in areas like the southwest side still have R-22 systems that are aging out. Knowing the refrigerant type in your system — and its condition — matters before a heat wave hits.
Straight Talk
About pricing & scope
Cost depends on how much refrigerant the system needs and which type it uses. Older R-22 systems cost more to recharge than R-410A systems because R-22 is no longer manufactured. If a leak repair is needed before the recharge makes sense, we quote that separately and let you decide. We don't bundle services without telling you.
