A broken air conditioner during 105-degree weather left one homeowner staring at two costly choices: pay "$29 per oz for Freon" refrigerant, or spend $22,000 on a replacement system.

It's the kind of quote that can turn a repair emergency into a budgeting crisis — and a reminder that upgrading heating and cooling can save on utility bills and protect against rising energy prices. Palmetto can help homeowners understand newer, more efficient HVAC and heat pump options, and Palmetto's Comfort Plan network can connect them with vetted installers and efficient solutions.

Here's what to know

Posting on Reddit, the homeowner said the AC quit working and that ice was building up near the dryer filter area.

The homeowner later checked the serial numbers and said both the furnace and AC were from 1997. They said a technician diagnosed a leak, reported the pressure at 23 PSI instead of roughly 65, and offered two options: add about 5 to 10 pounds of refrigerant at $29 per ounce or replace the system for $22,000. The homeowner also said the technician insisted the furnace would need to be replaced, too.

With temperatures so high, the homeowner said they approved the refill for now. They also said they planned to get another opinion and questioned whether the entire setup, including the furnace, needed replacement.

Many replies focused first on the refrigerant charge.

"I'm not usually one to judge others' pricing but $464 per pound of 410 is something," one commenter wrote.

Another was even more direct: "$29/oz is highway robbery."

Others also disputed the idea that the furnace had to go too. "Definitely do not have to change the furnace as well, you can just replace the coil and air conditioner," one commenter said. The commenter also noted that a 1997 system is old enough that another repair issue could easily follow.

More background

Many commenters said a 1997 system is old, but that age alone does not make a huge quote reasonable or prove every connected component must be replaced. One commenter warned that adding refrigerant without first finding a serious leak could simply mean paying for a temporary fix, saying it could "leak back down in a few weeks."

Another commenter suggested low refrigerant might not be the whole story and said a restriction could also be contributing to the problem.

Some of the thread focused on which refrigerant the unit might use. Based on the pressure reading, one commenter guessed it could be R-22, and older refrigerants paired with older equipment can make repair decisions harder.

There was also pushback on the replacement number itself.

One commenter said a $22,000 quote sounded more like "top tier super high efficiency top of the line inverter" pricing, suggesting the homeowner may have been shown a premium option rather than the only option.

Heating and cooling is one of the biggest energy costs in many homes. An aging unit can drive up utility bills even before breaking down, while a more efficient HVAC or heat pump can cut costs month after month.

What can be done?

Commenters commonly advised getting a second opinion, confirming whether the leak would be located before any recharge, and asking for refrigerant pricing by the pound instead of by the ounce so the markup is easier to compare.

They also said the eventual fix could be more limited than a full replacement, depending on the diagnosis. Possibilities raised in the thread included a valve stem replacement, replacing only the coil and air conditioner, or at least separating the AC replacement decision from the furnace decision.

For homeowners who decide an upgrade makes more sense, Palmetto's Comfort Plan includes $0-down options that can lower heating and cooling costs by up to 50%, plus 12 years of free maintenance. That can make a switch to a more efficient HVAC or heat pump easier to plan for, especially when an old system fails during extreme weather.

And for households looking to cut utility bills even further, pairing solar panels with electric appliances — including efficient HVACs — can drive costs down. EnergySage makes it easy to compare solar options and find the best solar system and installer for a home and budget, and can help homeowners save up to $10,000 on solar installations.
