Four questions that decide it

How old is it? Carrier puts the average central air conditioner at 15 to 20 years; Trane says about 15. Past 15, every major repair deserves a second look.
How big is the repair? A common contractor rule of thumb: when a single repair — or this year’s repairs added up — approaches half the cost of a new system, replacement usually wins. It’s a guide, not a law.
What refrigerant does it use? An R-22 system with a major leak or a failed compressor is usually the clearest case for replacement, because R-22 supply keeps shrinking.
Is it keeping the house comfortable? A system that runs all afternoon and still leaves the upstairs hot may have been undersized, oversized or fighting bad ductwork from day one. A repair won’t change that; a properly designed replacement can.

The refrigerant change, in plain terms

R-22	Production and import ended January 1, 2020. Recovered and reclaimed R-22 can still be used to service existing systems, and you’re not required to replace a working unit — but repairs that need refrigerant keep getting more expensive.
R-410A	The refrigerant now being phased out of new equipment. New residential split systems manufactured or imported from January 1, 2025 can’t use it. A May 2026 EPA rule lets installers keep installing systems whose components were all made before 2025, and R-410A remains available to service existing equipment.
R-454B and R-32	The main replacements. R-454B is common in ducted central air; R-32 in many ductless mini-splits. Both are classed A2L, “mildly flammable,” so technicians need specific training and equipment designed for them. They can’t be mixed with R-410A.

What it means for you: if your R-410A system is healthy, there’s no rule forcing you to replace it. If you are replacing, plan on a matched indoor coil and outdoor unit built for the new refrigerant.

Getting the size right for a Pueblo house

Bigger isn’t better. An oversized air conditioner cools in short bursts, cycles on and off, and leaves rooms uneven; an undersized one runs nonstop through a 100-degree week and still falls behind. The right size comes from a load calculation such as ACCA Manual J, which looks at the house itself — square footage, insulation, windows, which way the big windows face, duct condition — not just the size of the old unit.

That matters here. With the average Pueblo home now more than 55 years old, many houses have had windows, insulation and additions changed since the original system went in. The old unit’s size is a starting point, not the answer.

Rebates and credits worth checking

Black Hills Energy (electric customers in the city of Pueblo and north of Highway 50 in Pueblo West) lists 2026 residential rebates for high-efficiency central air conditioners and for early retirement of an existing central AC. The system must be an AHRI-certified matched set, installed new, and applied for after installation — for 2026 work, by January 31, 2027.
San Isabel Electric members (much of Pueblo West south of Highway 50) should ask the co-op what it currently offers; its programs change.
Heat pumps: Colorado’s Heat Pump Tax Credit continues in 2026. It’s claimed by a contractor registered with the Colorado Energy Office and passed to you as an upfront discount. The federal 25C home-improvement credit ended for equipment placed in service after December 31, 2025.

Rebate amounts change every year, so we don’t quote them here. Check the utility’s current application before you buy.

Questions we hear

Can I still get an R-410A system installed?

Sometimes. New split systems built or imported from January 1, 2025 must use a lower-impact refrigerant, mainly R-454B or R-32. A May 2026 EPA rule removed the old January 1, 2026 installation deadline for R-410A equipment, so systems whose components were all made or imported before 2025 can still be installed while that stock lasts. Availability varies; the technician will tell you what’s actually on offer.

Can you just replace the outdoor unit?

Rarely a good idea today. The indoor coil and outdoor unit are designed as a matched pair for one refrigerant, and the new refrigerants aren’t interchangeable with R-410A or R-22. Utility rebates also require an AHRI-certified matched system. Expect the estimate to cover both halves.

Does a new AC need a permit in Pueblo?

Yes, installing new equipment calls for a mechanical permit, and the licensed contractor pulls it. Since January 1, 2026, permits inside the City of Pueblo go through the Southern Colorado Building Department; in Pueblo West and the rest of unincorporated Pueblo County, through the county’s own building division.

Should I replace my furnace at the same time?

Not necessarily. If the furnace is young and working, a new AC can be matched to it. If both are near the end of their lives, doing them together means one installation and equipment designed to work together. A heat pump is another option that covers cooling and part or all of the heating.
