Let’s face it. Nobody buys a house thinking about what kind of refrigerant their AC uses. But if your home in Dover was built before 2010, your air conditioning system probably runs on R-22. And when that system conks out, the news from your technician is going to come with a price tag attached.
R-22 has been phased out by the EPA. Production stopped in 2020. What’s left is what’s left, and every year there’s a little less of it. That’s not a scare tactic. It’s just supply and demand, and we see it play out on every repair call in Crossgates, Kent Acres, and Rodney Village.
What the R-22 Phase-Out Actually Means
R-22, also called Freon, was the standard refrigerant for residential AC for decades. The EPA targeted it because of its ozone impact. Newer systems run R-410A, which doesn’t carry the same environmental cost.
Here’s the thing. Your old AC didn’t suddenly stop working because of the phase-out. It just got more expensive to keep alive. R-22 still exists, but it’s pulled from existing stockpiles and reclaimed from old systems. The per-pound price is several times what R-410A runs. When your system springs a small leak and needs a recharge, that’s where the bill starts climbing.
Why Dover Homes Get Hit Harder
A lot of Dover’s housing stock was built between 1960 and 1990. Ranch homes in Crossgates and Kent Acres. Modest two-stories in Rodney Village. Most of those AC systems were installed or replaced with R-22 units somewhere in the 1990s or early 2000s. Twenty-plus years is a respectable life for a condenser, but it also means the system was never designed for R-410A.
When a Hartly tech rolls up to a Dover home, the first conversation often goes like this. Your AC is low on refrigerant. The recharge will hold you over. But the leak that caused the loss is still there. And every recharge on R-22 costs more than the last one because the supply keeps shrinking.
You can patch it. We’ve done that for plenty of Dover customers who weren’t ready to replace. But eventually the math tilts toward a new system.
Repair, Recharge, or Replace?
Three decades of HVAC service has taught us not to give one-size-fits-all answers. But there are some honest rules of thumb for R-22 systems.
Repair makes sense when the system is under 12 years old, the leak is small and findable, and you don’t need more than a partial recharge. A quick top-up and a leak seal can buy you another summer or two.
Recharge alone is fine when you’re planning to replace soon and just need to get through the season. We don’t pretend that’s a long-term answer. We tell you that up front.
Replace makes sense when the leak is significant, the system is 15+ years old, you’re already paying for repeated recharges, or you’d rather put the repair money toward something that won’t keep costing you. R-410A systems are more efficient, run cleaner, and qualify for Delmarva Power and Energize Delaware rebates that can take a real chunk off the install price.
The Hidden Cost Nobody Tells You About
This is where the cookie-cutter HVAC outfits get themselves in trouble. They quote you a recharge and don’t mention that you’re going to be back on the schedule in eight months when the leak gets worse. We’ve seen homeowners spend more on three recharges than a new system would have cost over its lifespan.
Our techs are not salespeople. When the math says replacement, they tell you. When the math says one more recharge, they tell you that too. Either way, you get the numbers laid out before any work starts.
What to Ask Your HVAC Company
If you’re staring down an R-22 decision, here’s what a trustworthy company will tell you without being asked.
- How old is the unit, and what’s the typical remaining life?
- Is the leak repairable, or is it a slow loss across multiple joints?
- What’s the cost difference between this recharge and a full replacement, factoring in rebates?
- How long will the next recharge last given the current leak rate?
- Will replacement actually lower your monthly bills enough to matter?
If the answer to any of those is a vague shrug, get a second opinion.
