Overview

What refrigerant actually does — and why it matters when it's low

Refrigerant is the working fluid inside your AC — a closed-loop chemical that absorbs heat from your indoor air and releases it outdoors. A properly installed AC system never "uses up" refrigerant. If it's low, there is always a leak somewhere in the system. Shops that "just top it off" every summer without finding the leak are either ignorant or cutting corners. The refrigerant leaks out again within 3–6 months, and each recharge cycle costs more than the leak repair would have.

Low refrigerant shows up a handful of ways. AC blowing warm or lukewarm air even when it's running. Ice forming on the copper line between the outdoor condenser and the house. System running nonstop on a 90° day without bringing the house to set temp. Compressor short-cycling. Energy bill climbing without any change in usage. Any of those on a system that's been running fine for years is a leak until proven otherwise.

The three refrigerants you'll encounter

  • R-22 (Freon) — old-style refrigerant, phased out for new equipment in 2010 and banned from import/production in 2020. If your AC uses R-22, every pound of recharge now costs $125–$195, if you can get it at all. Systems using R-22 are usually 15+ years old and better replaced than recharged
  • R-410A (Puron) — the most common current refrigerant, used in virtually every AC installed between 2010 and 2024. Still readily available, recharge cost $45–$85/lb
  • R-32 — the new standard starting 2025. 30% lower global warming impact than R-410A, better efficiency, slightly higher pressure. New systems are shipping with R-32. Recharge $55–$95/lb

Why leaks happen in Utah

Utah conditions are tough on refrigerant systems. Temperature swings — 30°F overnight lows to 95°F afternoons in summer shoulder seasons — stress the braze joints and flare fittings. Dust and pollen coat the evaporator coil and hide pinhole leaks in the copper tubing. Hard water drip from the condensate line causes corrosion on nearby copper. Vibration from a long-running compressor (we run them 10–12 hours straight on peak days) loosens flare nuts. Cottonwood fluff in the outdoor coil reduces heat rejection, which raises head pressure, which accelerates leaks at weak points.

How a proper leak detection + repair works

We don't just dump refrigerant in and hope. Our process is: pressure check the system, identify whether the leak is slow (needs dye or electronic sniffer) or fast (audible hiss, oil stains on fittings). Electronic leak detection runs $145–$285 depending on system access. We find the leak, repair it (re-braze joint, replace flare, or in worst case recommend evaporator coil replacement), pull a full vacuum to 500 microns, hold it to prove the seal is tight, and then weigh in the factory-spec refrigerant charge. No "close enough on the gauges" charging.

What Valley does differently

Every refrigerant call starts with a leak search — we won't recharge a system without first finding and repairing the leak unless you specifically request a stopgap top-off and sign off on expecting the system to leak again. We're EPA Section 608 certified and file the required documentation for any refrigerant handling. If the leak is in the evaporator coil (a common failure on 8–12 year old systems), we give you honest repair vs. replace math — a new coil is $1,200–$2,200, and on a 12-year-old unit that's often the wrong call vs. replacing the whole system.

QSC HVAC members get 15% off both leak search and recharge labor, plus priority dispatch when the AC's warm and it's 95° outside.

Warning signs

Signs Your AC Is Low on Refrigerant

These symptoms almost always mean a refrigerant leak — not a refrigerant 'top-off.' Find the leak first.

  • AC runs but blows lukewarm or room-temp air

  • Ice forming on the larger copper line between outdoor unit and house

  • Ice on the indoor evaporator coil (turn system off immediately)

  • System runs constantly without reaching set temp on hot days

  • Hissing or bubbling sound near the indoor air handler or outdoor unit

  • Oily residue or stains around line-set fittings or coil connections

  • Power bill jumped 20%+ without usage change

  • Short cycling — compressor clicks off within minutes of starting

  • AC was recharged last summer and is already struggling again

  • System is 10+ years old and refrigerant work has been repeated before

Find the leak first

Refrigerant doesn't 'get used up.' If it's low, it's leaking.

Every recharge without leak repair just pays for the leak to happen again. We find it, seal it, and charge to factory spec.

The Process

How a Valley Refrigerant Service Call Works

On the truck

Cable machine, jetter, and pipe camera — every call.

  1. Diagnostic and pressure check

    Tech connects manifold gauges, reads suction and liquid pressures, calculates subcooling and superheat. Confirms low-refrigerant fault and rules out other causes (dirty coil, failed metering device, restricted airflow).

  2. Leak detection

    For slow leaks, we use electronic leak detector (or UV dye if needed). For fast leaks, audible/oil-stain inspection usually locates it in 10 minutes. Tech shows you where the leak is before quoting the repair.

  3. Repair the leak

    Most leaks are at flare fittings or braze joints — we re-braze under nitrogen, tighten or replace flares. Bigger leaks (evaporator coil, condenser coil) get quoted on-site with honest repair-vs-replace math before we proceed.

  4. Evacuate and recharge

    Pull full vacuum to 500 microns, hold 30+ minutes to prove the seal. Weigh in factory-spec refrigerant charge by the pound — not guessed by gauge pressures. Check subcooling to confirm correct.

  5. Verify cooling and log

    Run system in full cool mode, measure temperature split across the coil (18–22°F target), confirm pressure readings match spec. EPA Section 608 documentation filed. You get a printed service report.

R-22 vs. R-410A vs. R-32 — What's in Your System

Which refrigerant your AC uses determines repair economics. If you're on R-22, the math usually says replace.

FAQ

Refrigerant FAQs

For R-410A, recharge runs $85–$135 per pound, and a typical 3-ton system holds 6–10 lbs depending on line length — so a full recharge is $425–$675 plus any leak repair. R-32 runs slightly higher per pound. R-22 recharge is $145–$225/lb when available and usually means it's time to replace the system instead.
