Question 1

How do I know if my AC is low on refrigerant?

Accepted Answer

Common indicators include diminished cooling, ice buildup on the refrigerant lines or indoor coil, the system running nonstop without hitting the target temperature, and warm air at the supply vents. A technician confirms with a pressure reading.

Question 2

How much does an AC refrigerant recharge cost?

Accepted Answer

R-410A recharges generally range from $200 to $500 based on the amount needed. R-22 costs substantially more because of limited reclaimed supply — typically $100 to $200 per pound on top of the service call.

Question 3

Can I buy refrigerant and recharge my AC myself?

Accepted Answer

No. Federal EPA regulations restrict the purchase and handling of HVAC refrigerants to EPA-certified technicians. Beyond the legal requirement, refrigerant is a pressurized chemical that demands proper equipment for safe handling.

Question 4

What's the difference between R-22 and R-410A refrigerant?

Accepted Answer

R-22 (Freon) is an older refrigerant that depletes the ozone layer — it was banned from production in the U.S. in 2020 and is now extremely expensive. R-410A (Puron) replaced it as the industry standard; it operates at higher pressures and is more efficient, but requires equipment specifically designed for it. You cannot put R-410A in an R-22 system — the components aren't rated for the higher pressure.

Question 5

What is R-454B refrigerant and why does it matter?

Accepted Answer

R-454B is the next-generation refrigerant replacing R-410A in new residential equipment starting in 2025. It has a much lower global warming potential (GWP) than R-410A, which is why the EPA is phasing R-410A down. R-454B is classified as a mildly flammable A2L refrigerant, so it requires updated safety standards and trained technicians — our team is already certified for A2L handling.

Question 6

Is R-22 Freon still available? How much does it cost?

Accepted Answer

R-22 is still available from reclaimed and stockpiled supplies, but the price has skyrocketed — expect $150–250 per pound or more, meaning a full recharge can cost $600–1,500+. By comparison, R-410A runs about $50–75 per pound. If your R-22 system needs a major refrigerant charge, it's usually more cost-effective to replace the entire system with a modern R-410A or R-454B unit.

Question 7

When was R-22 Freon phased out?

Accepted Answer

The production and import of R-22 was completely banned in the United States on January 1, 2020 under the Clean Air Act. Existing R-22 systems can still be serviced using reclaimed or stockpiled refrigerant, but the supply is shrinking every year and prices keep climbing. If you're still running an R-22 system here in WNC, we strongly recommend planning a replacement sooner rather than later.

Question 8

Should I replace my R-22 AC system or just keep recharging it?

Accepted Answer

If your R-22 system only has a minor leak and is otherwise in good condition, a recharge plus leak repair might buy you a year or two. But if it's over 15 years old or needs a major repair, replacement is the smarter investment — you'll get a more efficient system, lower operating costs, and avoid the escalating R-22 prices. Most of our customers in the Asheville area save enough on energy bills to offset a significant portion of the replacement cost within 5–7 years.

Question 9

What is the R-410A phase-down and when does it happen?

Accepted Answer

The EPA's AIM Act is phasing down R-410A production by 40% starting in 2024, with further reductions through 2036. R-410A won't disappear overnight — it'll remain available for servicing existing equipment for years — but new equipment manufactured after January 1, 2025 will transition to R-454B. If you're installing a new system now, ask us about R-454B-ready equipment to future-proof your investment.

Question 10

What are the signs of a refrigerant leak in my AC?

Accepted Answer

Common signs include the system blowing warm air, ice forming on the evaporator coil or refrigerant lines, a hissing or bubbling sound near the indoor or outdoor unit, and higher-than-normal electric bills from the compressor working overtime. In severe cases, you'll notice the system running constantly without reaching the set temperature. We use electronic leak detectors and UV dye to pinpoint the exact location of the leak.
