In the middle of July, a South Minneapolis home was pushing warm air out of every vent. The outdoor unit was an older Lennox running on R-22 refrigerant, and it had lost its charge.
The homeowner came to us through a remodeling contractor we work with regularly, who called and asked us to get out there. When we looked at the condenser, the fins were beaten up from years of weather, and the unit's age told most of the story on its own. Replacing an air conditioner in Minneapolis during a heat wave is urgent work, and the first job was figuring out whether this one was worth repairing at all.
Key Takeaways
- THE CHALLENGEAn aging R-22 air conditioner had stopped cooling a South Minneapolis home during July heat, and recycled R-22 refrigerant is expensive enough to change the repair math.
- THE SYSTEMWe presented repair and replacement options, then installed a Goodman air conditioner chosen for its 12-year warranty and wide parts availability.
- THE RESULTRefrigerant was set to the manufacturer's schematics, the supply-and-return temperature split was verified on site, and the homeowner felt the house cooling within about half an hour.
We do not assume an old system needs replacing. In this case we laid out what it would take to recharge and keep the existing R-22 unit running, and what a new system would cost — the gap worked out to roughly $500 to $600 more for new equipment rather than putting recycled refrigerant into a tired condenser. With that comparison in front of her, the homeowner chose replacement, and we scheduled the install.
Project Summary
| Client Profile: | Homeowner in South Minneapolis, referred by a remodeling contractor |
| Project Location: | South Minneapolis, Minnesota |
| Primary Objective: | Restore cooling to the home in July, starting with a diagnostic visit from our Air Conditioner Repair team before any equipment was recommended |
| System Installed: | A Goodman air conditioner, selected for its 12-year warranty and parts availability, handled by our AC Replacement crew |
| Key Outcome: | Cooling restored and verified by supply and return temperature readings, with a 5-star review from the homeowner |
Diagnosing a Failing R-22 Air Conditioner
The condenser outside was old enough that the fins had been flattened in spots, most likely from hailstorms over the years. The system was charged with R-22, a refrigerant that has been phased out of production and is now only available as recycled stock. That matters to a homeowner, because the cost of recharging a leaking R-22 system is no longer a small repair bill.
A small refrigerant leak on a system that age rarely stays a small problem. We walked through the options — chase the leak and recharge with recycled R-22, or put that money toward a new condenser running current refrigerant. When the price difference between those two paths lands in the $500 to $600 range, most homeowners want to hear the full comparison before deciding, and that is the conversation we had here.
Installing the New Goodman Condenser
We went with Goodman for the replacement. Across the board it carries a 12-year warranty instead of the more common 10, and parts are easy to source — any HVAC technician in the Twin Cities can find an inducer motor or a control board for one, which matters years down the road when a part finally fails. Goodman units also tend to have fewer mechanical quirks built into them, which is part of why the longer warranty holds up. Older Minneapolis homes bring their own install challenges: units that were originally set on a sidewalk often need to be relocated to the backyard, and getting lines through old flagstone brick is usually the slowest part of the day.
"Modern Plumbing installed an HVAC system as part of renovation for this home. A renovator company contracted out to Modern Plumbing, and other sub-contractors. Various issues and lack of clean up by other providers occurred here, but Modern Plumbing came out to check that none of the debris was from their work- volitionally! I had informed my agent that I was quite sure Modern Plumbing was not responsible for the debris, and they came out to check nonetheless. I was super-impressed! 5 stars to Wayne and his crew!" - (Gail, Homeowner)
Because the job came to us through a remodeling contractor, coordination mattered as much as the mechanical work. We scheduled around the other trades on site, kept the homeowner informed, and finished the air conditioner as a standalone project rather than pushing a full system swap she did not ask for. Homeowners who want to spread a replacement over time can look at our Financing Options, and we also handle AC Maintenance once the new equipment is in.
Verified Cooling Before We Left
A new condenser sitting outside does not prove anything on its own. We hook up gauges, set the refrigerant level to the manufacturer's schematics, then measure the temperature at the supply register and at the return. On a properly operating system you are looking for a meaningful split between the two — with the old unit, that difference simply was not there.
The homeowner could feel the change before we finished packing up, which is typically the case within about half an hour of startup. Showing someone the thermostat dropping and the cold air coming out of the register is a better proof of work than any paperwork, and it is how we close out every Cooling Services call. The Goodman system's 12-year warranty and easy parts availability mean future service on this house should be straightforward.

Frequently Asked Questions
Is an R-22 air conditioner worth repairing in Minneapolis?
Sometimes, but the refrigerant cost changes the math. R-22 is no longer produced, and recycled stock is expensive enough that recharging a leaking older unit can come within a few hundred dollars of a new system. We price both paths and let you decide — on this South Minneapolis job, the difference was roughly $500 to $600.
Can you replace just the AC and keep my furnace?
Often yes, which is what we did on this project. Some furnaces accept conversion kits so they can work with newer refrigerants and control wiring, while others are old enough that replacing both makes more sense. We check the age and compatibility of the existing furnace before quoting the air conditioner.
What warranty comes with a new Goodman air conditioner?
Goodman equipment carries a 12-year warranty across the board, compared with the 10-year coverage common on other brands. Parts are also widely stocked, so a future repair is less likely to turn into a long wait. Annual tune-ups and regular filter changes help keep that coverage meaningful over the life of the system.
