AfterRefrigerant Recharge in Houston, TX
A refrigerant recharge in Houston typically runs $200 – $450 for most residential systems, depending on how low the charge is and whether your system uses R-410A or the older R-22. The job itself takes 45 – 90 minutes once the leak is ruled out or addressed. If your AC is blowing warm air or short-cycling in July, call Dalton Heating & Air Houston at (903) 494-7686 for AC Repair & Installation Near Me in Houston, TX and we’ll get the pressures checked the same day.
A refrigerant recharge means topping off the cooling fluid your system needs to pull heat out of your house. When the charge drops, your AC loses capacity. It runs longer, cools less, and pushes your electric bill up with nothing to show for it. We handle refrigerant work as part of our broader AC Repair & Installation in Houston service, and we do it under the same rules we’ve followed since 2003: written price before work starts, written guarantee on the repair, and a return visit at no charge if it doesn’t hold.
Key Takeaways:
- Most Houston refrigerant recharges cost $200 – $450, depending on refrigerant type and volume.
- Refrigerant doesn’t get “used up” – a low charge means there’s a leak that needs to be found.
- Dalton Heating & Air gives you the price in writing before any work begins. Always.
- Every recharge includes a written one-year guarantee. If it fails, we come back free.
When You Need Refrigerant Recharge
Here’s what Houston homeowners actually notice when the charge is low. Any one of these is worth a service call, and several together usually point straight at refrigerant.
- Warm air from the vents. The system runs, but the air coming out is only slightly cooler than the room. In a Houston summer, that’s not air conditioning – that’s a fan with extra steps.
- Longer run times without reaching set temperature. You set the thermostat at 74, the unit runs for three hours, and the house is still at 78. A low charge drops system capacity fast.
- Frost or ice on the copper lines. The larger copper line at the condenser outside may frost up. If it’s frozen solid, the system is starving for refrigerant and the evaporator coil can ice over completely.
- Hissing or bubbling sounds near the indoor coil. That’s refrigerant escaping under pressure. Small leaks in coil tubing or brazed joints make a faint noise you can sometimes hear when the system is running.
- Electric bill climbing with no change in usage. A system down a pound or two of refrigerant can run 20 – 40% longer to do the same job. You pay the difference every month.
- Short cycling in extreme heat. Low refrigerant can cause the compressor to overheat and trip its internal limit. The unit starts, runs ten minutes, shuts off, repeats all afternoon.
The important thing to know: refrigerant doesn’t get consumed or wear out. If it’s low, something leaked, and just adding refrigerant without finding the leak means you’ll be back in the same spot next summer. We test with an electronic leak detector and a UV dye process when the leak isn’t obvious. In Houston’s humidity and heat, a system that leaks in April becomes an emergency by August. Catching it before the first 95-degree stretch saves money and a miserable weekend.
Our Refrigerant Recharge Process
Every recharge follows the same sequence. We don’t top off a system and leave. We find out why it was low in the first place, because adding refrigerant to a leaking system without locating the leak is a temporary patch, not a repair.
- System diagnostic and pressure check. The technician hooks gauges to both service ports and measures the current pressures against manufacturer specs for the outdoor temperature. That tells us how far off the charge is. We also check the temperature split at the return and supply vents.
- Leak assessment. If the charge is low, we look for the source. We use an electronic leak detector at the coil, the line set connections, and the condenser. For slow, stubborn leaks we run a UV dye through the system and come back to pinpoint it. Leaks at the Schrader valve or a flare fitting are often simple fixes. Leaks in the evaporator coil are a bigger decision, and we’ll give you the numbers to make that call.
- Written price before any work starts. After the diagnostic, you get a line-item quote for the recharge, any leak repair, and the refrigerant itself. You approve the number before a wrench turns. No tech springs a surprise at the end of the job.
- Evacuation and recharge to manufacturer spec. If a leak repair requires opening the system, we pull a vacuum to remove moisture and non-condensables, then weigh in refrigerant to the exact ounce the manufacturer calls for. Trane, Carrier, Lennox, and Goodman systems all have specific charge requirements, and we service every one of those brands.
- Post-repair verification. We confirm the temperature split is right, the superheat and subcooling match spec, and the system is cycling normally. You get the refrigerant levels and final operating pressures in writing.
- Written one-year guarantee. Every recharge comes with our 365-Day Done Right Promise in writing. If the repair fails within a full year, we return at no charge. That’s The Garrison Standard, and it’s been the rule since 2003.
This is the same process we use on every AC repair in Houston – no shortcuts on the diagnostic, no adding refrigerant blind. You’d be surprised how many systems we see that were overcharged by someone in a hurry, which reduces efficiency and shortens compressor life.
Refrigerant Recharge Pricing in Houston
What you’ll actually pay depends on three things: what refrigerant your system uses, how much it needs, and whether there’s a leak repair bundled in. Here’s a straight breakdown of the numbers we see across Houston.
| Service | Typical Range | Notes |
|---|---|---|
| R-410A recharge (1 – 2 lbs) | $180 – $320 | Most common for systems built after 2010 |
| R-22 recharge (1 – 2 lbs) | $250 – $450 | Phased out – supply is low, price per pound is high |
| Recharge with UV dye leak test | Add $60 – $100 | Used for slow leaks that don’t show on electronic detection |
| Evaporator coil replacement (if leaking) | $900 – $2,200 | Depends on the brand and whether the coil is under warranty |
| Full diagnostic (applied toward repair) | $79 – $129 | Written quote provided before any work begins |
If your system runs R-22, the price per pound keeps climbing because production stopped years ago. Some older systems need four or five pounds to top off. At that point, replacing the system or converting components often makes more sense than feeding an aging unit expensive refrigerant, and we’ll tell you that straight rather than selling you another recharge.
The diagnostic fee comes off your total if you proceed with the repair. Estimates are free, and the number we write down before starting is the number you pay. No add-ons, no “while I was in there” surprises. That’s part of The Garrison Code, and it’s not a suggestion – it’s how every Dalton Heating & Air Houston call is run.

FAQs – Refrigerant Recharge
How much does a refrigerant recharge cost in Houston?
A residential refrigerant recharge in Houston typically costs $200 – $450 depending on refrigerant type and volume, with R-22 on the higher end. If a leak must be repaired first, that’s an additional cost we quote in writing before starting. Call (903) 494-7686 for an exact quote after a quick system check.
How do I know if my AC just needs a recharge?
If the system is blowing warm air, running constantly without cooling, or has ice forming on the copper line at the condenser, the charge may be low. A low charge almost always means a leak, not normal depletion. We confirm with a pressure and temperature check before adding anything.
Is it cheaper to recharge or replace the AC?
For a healthy system under 10 years old with a minor leak, a recharge plus leak repair is the lower-cost fix. For an older R-22 unit losing multiple pounds a year, replacement often pays for itself in avoided repeat recharges within three to five years. We’ll give you the numbers for both paths before you decide.
Can you recharge my AC the same day?
In most cases, yes. We keep recharging stock for R-410A systems on every truck and can usually complete a AC repair installation recharge and leak check the same morning. Calls are answered by a live person 24/7, so call (903) 494-7686 and we’ll get a technician to your neighborhood in Houston the same day.
How long does a refrigerant recharge last?
If the leak is found and repaired, a recharge should last for years. If refrigerant was simply added without locating the leak, it will eventually escape again. That’s why Dalton Heating & Air won’t recharge a system without first determining where the refrigerant went.
What refrigerant do new Houston AC systems use?
Most residential systems installed after 2010 run on R-410A, but manufacturers are transitioning to R-454B and R-32 for newer models. We service Trane, Carrier, Lennox, and Goodman units and match the refrigerant to the manufacturer’s spec exactly.
