AfterRefrigerant Recharge in Marietta, GA
A refrigerant recharge in Marietta typically costs between $220 and $480, depending on how low your system has run and whether it uses R-410A or the newer A2L refrigerant. It’s the process of topping off the cooling fluid your AC needs to pull heat out of your home’s air, and it usually takes a technician 45 to 90 minutes. If your system is blowing warm air on a July afternoon in East Cobb, call Cold Harbour Heating and Air Marietta at (762) 240-5599 and we’ll get a technician to you the same day.
We’ve been handling refrigerant work in Cobb County since 2003, and we’re part of the home service network that makes up the Kingswell group of independently owned HVAC companies. What that means for you is simple: we work to a written standard called the Kingswell Way, and that standard starts with telling you the price before a single tool comes out of the truck. There’s more to a good recharge than hooking up a gauge set, and we walk you through exactly what we find before we add a drop of refrigerant.
If your AC has lost refrigerant, you’ve got a leak somewhere. A conscientious company doesn’t just top the system off and wave goodbye. We find the leak, show you where it is, and give you a written repair price. That’s the difference between a recharge that lasts a season and one that lasts a few weeks. For a full picture of what we do, see our AC Repair & Installation in Marietta page.
When You Need a Refrigerant Recharge
Here are the telltale signs we hear about most often from homeowners across Marietta, from Whitlock Avenue to the neighborhoods off Roswell Road:
- Warm air from the vents. Low refrigerant means the coil can’t absorb enough heat. Your system runs, but the air coming out feels room temperature or worse.
- Longer run times, higher bills. When refrigerant is low, your AC has to work harder to hit the thermostat setting. You’ll see it in your Georgia Power bill before you feel it in the living room.
- Ice on the refrigerant line. That copper line running to your outside unit should never be frozen. Ice means the system pressure has dropped and the evaporator coil is frosting over. We see this regularly on Trane and Carrier systems in Marietta as they age past the 8-10 year mark.
- Hissing or bubbling near the indoor unit. That’s the sound of refrigerant escaping through a pinhole leak in the coil or line set. It’ll be faint, but on a quiet morning you can catch it.
- System short-cycling. Low refrigerant can trigger your low-pressure switch, making the system start and stop every few minutes. It’s hard on the compressor and it never cools the house down.
- The AC hasn’t been serviced in years. Refrigerant doesn’t get used up like gas in a car. If you’re low, you have a leak, and a recharge without a leak fix is throwing money away. A Lennox or Goodman system that’s five years old and never been checked is a prime candidate.
One thing worth being direct about: refrigerant is not a consumable. A properly sealed system holds its charge for the life of the unit. If yours is low, something is wrong, and that something needs to be found.
Our Refrigerant Recharge Process
Here’s how a recharge works when you call Cold Harbour Heating and Air Marietta for AC repair installation. It’s the same process every time, and it follows the Kingswell Way: say the price before the work, show up in the window given, leave the place cleaner than found, put the guarantee in writing, and come back if it fails.
- We confirm the symptoms and schedule a window. When you call (762) 240-5599, a live person answers, not a voicemail tree. We’ll ask what you’re seeing and set a firm arrival window that works for you.
- The technician arrives, inspects, and tests. We check system pressures against manufacturer specs, measure the temperature drop across the coil, and look for oil stains that point to a leak. On Rheem and Trane units especially, we check the Schrader valve cores, which are a common leak point.
- We find the leak, not just the symptom. We use an electronic leak detector and, when needed, a UV dye injection to pinpoint exactly where refrigerant is escaping. In Marietta’s humidity, coil corrosion is a frequent culprit on older systems near the Chattahoochee.
- You get a written price before any work begins. We hand you the number in writing: the cost to repair the leak, the cost to recharge the system to the manufacturer’s specified charge, and the total. That number does not change at the door.
- We perform the repair and recharge to spec. We fix the leak, pull a proper vacuum to remove moisture and non-condensables, and charge the system by weight according to the manufacturer’s data plate. No guesswork, no “close enough.”
- We verify performance and leave you the guarantee. Before we leave, we test the temperature split and system pressures again. You get a written 365-Day Done Right Promise on the repair. If it fails within a year, we come back and make it right at no charge.
Refrigerant Recharge Pricing in Marietta
Here’s what refrigerant work costs in the Marietta market, based on what we’ve seen across Cobb County over the last several years. These are real numbers, not teaser rates.
| Service | Typical Price Range | What’s Included |
|---|---|---|
| Basic refrigerant recharge (R-410A) | $220 – $380 | Diagnostic, leak check, refrigerant, labor |
| Recharge with minor leak repair | $350 – $550 | Leak repair (valve core, line set fitting), recharge, retest |
| Recharge with evaporator coil replacement | $1,400 – $2,600 | New coil, refrigerant, nitrogen purge, recharge, labor |
| R-22 recharge (legacy systems) | $150 – $300 per pound | Refrigerant only; R-22 is being phased out and is increasingly expensive |
What affects your final price? Three things mainly. First, the type of refrigerant: R-410A is the most common in systems built between 2010 and 2024. Newer systems run A2L refrigerants, which are pricier per pound. Older systems may still run R-22, which is being phased out federally and now costs more than many homeowners expect. Second, the size of the leak: a Schrader valve replacement is a $40 part. A rusted evaporator coil is a much bigger job. Third, how low the system is: a system that’s 20% low takes a fraction of what a nearly empty system needs.
We’ll always give you the written price before we start. Estimates are free. Call (762) 240-5599 and we’ll send a technician to your door, not a salesman.
FAQs – Refrigerant Recharge
How much does a refrigerant recharge cost in Marietta?
A refrigerant recharge in Marietta typically runs between $220 and $480 for most modern R-410A systems, while older R-22 systems can push past $600 depending on how many pounds are needed. The variables are the refrigerant type, the leak location, and the system’s total capacity. Call (762) 240-5599 for a free estimate, and we’ll put the exact number in writing before any work starts.
Can you recharge my AC the same day I call?
Yes, in most cases we can get a technician to your Marietta home the same day for AC Repair & Installation Near Me in Marietta, GA, and we answer the phone with a live person 24 hours a day, 7 days a week. Refrigerant recharges are a same-day job for us because we keep common refrigerants and leak-repair parts stocked on our trucks. Call (762) 240-5599 and we’ll give you a firm arrival window.
Is it cheaper to recharge or replace my AC?
A recharge is cheaper in the short term, at $220 to $480 versus $6,000 to $12,000 for a full AC Installation in Marietta, but if your system is over 12 years old or leaking from the evaporator coil, repeated recharges stop making financial sense. We’ll always give you both options with written pricing so you can decide based on numbers, not pressure. If a recharge is the right call, we’ll say so. If it’s not, we’ll tell you that too.
Why does my AC lose refrigerant in the first place?
Your AC loses refrigerant because of a leak, not because refrigerant gets used up. Common leak points in Marietta systems include the evaporator coil (which corrodes in our humid summers), Schrader valve cores, and brazed joints in the line set. The fix is to locate the leak, repair it, and recharge to the manufacturer’s specified weight. If a company wants to recharge without finding the leak, walk away.
Is refrigerant recharge covered by the 365-Day Done Right Promise?
Yes, every leak repair and recharge we perform in Marietta is covered by our 365-Day Done Right Promise in writing. If the repair fails within a full year, we come back and correct the work at no additional charge. The guarantee is on paper before the technician leaves your home.
