Here's the sentence that costs Frankfort homeowners the most money over a decade: 'The AC just needs Freon every summer.' Air conditioners are sealed systems — refrigerant doesn't get consumed, it circulates forever. If charge needs topping annually, the system isn't thirsty; it's leaking. And every recharge you buy is a payment on a problem that's getting worse.
This is the leak conversation we have in Tanglewood and Woodlake kitchens every June — the signs, the stakes, and the honest fix-versus-feed math.
The Signs Your System Is Leaking
The signature symptom: annual recharges. If a tech added refrigerant last summer and the cooling fades again this June, the leak is proven by history. Physical signs include ice on the copper line set or coil (low charge drops coil temperature below freezing even in July), hissing or bubbling at joints, oily residue at fittings or under the unit (refrigerant circulates with oil), andlukewarm supply air with long runtimes.
The bill-shaped signs: climbing summer electric costs, a house that never quite reaches setpoint, and a compressor that sounds increasingly tired — running low starves the compressor of cooling oil and sends it toward the most expensive failure in the system.

Where Leaks Hide
The usual suspects: the evaporator coil (formicary corrosion from household VOCs eats pinholes over years — the classic hidden leak), the condenser coil (stones from trimmers, hail, corrosion), Schrader valve cores (a $4 part that leaks like a sieve when worn), and line sets — especially where vibration, sun, or critters have worked on them. Flared joints and brazed connections round out the list.
Finding them properly takes instruments: electronic detectors, UV dye where useful, and nitrogen pressure testing for the stubborn ones. We show you the leak's location and photos before pricing anything.

Call +1 (327) 210-5999The R-22 Problem: When the Math Flips
Refrigerant type changes everything. R-410A (systems roughly 2010 and newer) is affordable and available — fixing a leak is usually straightforward economics. R-22 (older systems) is phased out: remaining supplies are expensive, and every year they get more so. A leaking R-22 system faces repeated expensive recharges on equipment that's already past its design life.
That's why 'my 2004 system needs Freon' is a replacement conversation, not a repair quote. We model it both ways — with the honest odds for each — and let the numbers decide. What we won't do is sell an R-22 recharge and a pat on the head.
The Right Repair, Start to Finish
A proper leak repair: locate and show the leak, repair or replace the failed component, pressure-test with nitrogen to prove the seal, pull a deep vacuum to remove moisture and air, and weigh in the exact factory charge — not a 'fill 'er up' approximation. Then verify performance with real measurements and warranty the work.
The shortcut version — top off the charge, skip the search — is how a $300 leak repair becomes a $4,000 compressor replacement three summers later. EPA-certified recovery and handling aren't optional extras; they're the law and the difference between a fix and a lease.
What to Do This Week
If your system has been 'recharged' more than once, stop paying the subscription and get the leak found. If you're seeing ice, hearing hissing, or noticing the oily residue, shut the system off — running low damages the compressor — and call. If a tech ever says 'it just uses Freon,' get a second opinion, and we'll gladly be it.
Call +1 (327) 210-5999. Leak detection is a same-week service in our schedule, and finding it in June is dramatically cheaper than feeding it every summer.
The Bottom Line
Annual refrigerant top-offs are a subscription, not a repair. Sealed systems leak; leaks get found with instruments and fixed properly, or they eat compressors. If your system has been recharged more than once, stop paying and get the leak located — June detection is dramatically cheaper than a third summer of Freon.
Frequently Asked Questions
We'd talk you out of it. DIY kits mask the leak, risk overcharging, can't distinguish leak types, and mixing sealants or refrigerants complicates professional repair badly. A sealed system that needs charge has a leak worth finding properly.
Most leaks are found in a single visit — an hour or two of testing. Coil-internal and intermittent leaks can take nitrogen testing and a longer window; we tell you which situation you're in before the meter runs long.
Residential-level leaks aren't a household toxin emergency, but the equipment damage is real and running low compounds it fast. If you hear active hissing or smell odd chemical odors, shut the system off and call.
