AC installation in Kearns has a particular character because Kearns has a particular housing pattern. Many original 1950s and 1960s Kearns homes were built without central AC — the original construction included heating systems but cooling was addressed through evaporative coolers, window units, or simply opening windows during summer. Over the decades, homeowners have added central AC at various points as comfort expectations evolved, summer temperatures became more challenging, and AC equipment became more affordable. Today’s Kearns AC installation work splits between AC additions to homes that originally only had heating, system replacements where existing AC equipment has reached end of service life, complete system upgrades pairing new AC with new furnace, conversions from R-22 systems to current refrigerant equipment, and the occasional new construction installation in newer southern Kearns subdivisions.
Each scenario involves different considerations. AC additions to original heating-only homes require electrical verification, outdoor unit placement on Kearns’ typically modest lot sizes, refrigerant lineset routing through existing wall cavities, evaporator coil installation in the existing furnace, and condensate drainage installation. System replacements when existing AC is functional but aging require evaluation of indoor coil matching, refrigerant compatibility, and electrical service adequacy. R-22 conversions involve complete refrigerant system replacement because R-22 systems can’t be converted to R-410A or newer refrigerants without component replacement. The right approach depends on your specific home, existing equipment, and priorities.
Below is what AC installation involves done properly, the common scenarios we encounter in Kearns, what installation projects typically look like, and how to think about equipment selection.
AC Installation Scenarios in Kearns
AC Addition to Original Heating-Only Home
Common scenario in original Kearns construction. Existing furnace remains as heating source and air handler for cooling; new AC condenser installed outdoors; refrigerant lines routed between them; evaporator coil installed in or above the furnace; condensate drainage installed; thermostat upgraded if needed.
Project considerations:
- Electrical service verification — older Kearns homes sometimes have 100A service that may need evaluation for AC compressor addition. 200A service typically accommodates AC addition without service upgrade.
- Outdoor unit placement — Kearns lots are typically modest, requiring careful placement for proper clearances, noise considerations, and aesthetics
- Refrigerant lineset routing — through wall cavities, attic space, or exterior pathway depending on home configuration
- Evaporator coil installation — typically installed in the supply plenum above the furnace, sometimes requiring plenum modifications
- Furnace compatibility — older furnaces sometimes have blower capacity inadequate for AC airflow requirements, requiring evaluation
- Thermostat upgrade — older heating-only thermostats need replacement with cooling-capable models
- Condensate drainage — gravity drain where available, condensate pump where needed
Typical duration: 1–2 days on-site depending on accessibility and complexity
Typical pricing: $7,000–$14,000 depending on equipment tier and installation complexity
System Replacement (Aging AC)
Replacing existing AC equipment that has reached end of service life. Existing furnace remains in place (unless also being replaced); outdoor condenser replaced; evaporator coil typically replaced for proper component matching; refrigerant system commissioned with current refrigerant.
Typical pricing:
- Standard single-stage AC: $5,500–$8,500
- Two-stage AC: $7,500–$10,500
- Variable-speed AC: $11,000–$16,000
R-22 System Conversion
Older Kearns AC systems (typically pre-2010 installations) use R-22 refrigerant. R-22 has become increasingly expensive and harder to source ($150–$275 per pound), making continued service on R-22 equipment uneconomic for many customers. Conversion to current refrigerant requires complete refrigerant system replacement:
- R-22 refrigerant recovery (EPA-required, no atmospheric venting)
- System flush to remove R-22 residue
- New outdoor condenser
- New evaporator coil
- New refrigerant lineset (in some cases, depending on existing line condition and refrigerant compatibility)
- Commissioning with current refrigerant
Typical pricing: matches new AC installation tiers, $5,500–$16,000 depending on equipment selected
Complete System Replacement (Furnace + AC)
Both heating and cooling equipment replaced together for matched-component performance. Common when both components reach end of service life simultaneously, when efficiency upgrades are desired across the system, or when current equipment doesn’t match well.
Advantages of combined replacement:
- Matched components for optimal efficiency
- Single project rather than two separate installations
- Integrated commissioning
- Potential matching equipment rebates
- Smart thermostat configuration optimized for both new components
Typical pricing:
- Standard combined replacement: $10,000–$16,000
- Premium combined replacement: $14,000–$22,000
- High-end variable-speed combined replacement: $18,000–$28,000+
Heat Pump as AC Alternative
Heat pumps provide both cooling (in cooling mode) and heating (in heating mode), often replacing both furnace and AC with a single system. Kearns heat pump considerations:
- Cold-climate heat pump suitability — Salt Lake’s 14°F winter design temperature is within reasonable cold-climate heat pump performance range
- Dual-fuel system option — heat pump primary with gas furnace backup for severe cold, eliminating performance concerns during deep winter
- Federal 25C tax credit up to $2,000 on qualifying heat pumps (vs. $600 on furnaces)
- IRA Home Electrification rebates up to $8,000 for income-qualified households
Typical pricing:
- Standard heat pump: $6,500–$10,500
- Two-stage heat pump: $9,000–$14,000
- Cold-climate variable-speed heat pump: $14,000–$22,000
- Dual-fuel system: $14,000–$24,000
Swamp Cooler to Central AC Conversion
Some Kearns homes have operated on swamp cooler systems for decades and customers are ready to upgrade to refrigeration-based central AC. Conversion involves:
- Swamp cooler removal (typically from roof)
- Roof patching where swamp cooler was mounted
- New AC condenser installation at ground level
- Evaporator coil installation in existing furnace
- Refrigerant lineset routing
- Ductwork modifications if existing system relied on swamp cooler-specific ductwork
- Thermostat upgrade
- Condensate drainage installation
Typical pricing: $8,000–$14,000
What Proper AC Installation Includes
Manual J Load Calculation
The proper way to size AC equipment. Manual J calculates actual cooling load based on home characteristics, climate conditions, and Salt Lake’s altitude-corrected design temperatures. Properly sized equipment matches actual load; oversized equipment (common when contractors size from existing equipment or square-footage rules) short-cycles and dehumidifies poorly.
Altitude Correction
Salt Lake’s 4,300-foot elevation requires altitude correction per manufacturer specifications for cooling equipment.
Refrigerant System Procedures
- Nitrogen purge during brazing prevents oxide formation inside copper tubing
- Vacuum to 500 microns held verifies system dryness
- Charge by weight per manufacturer specification rather than estimated by gauges
- Verification by superheat or subcool method at actual operating conditions
Electrical and Drainage
- Proper amperage circuit sized for AC compressor
- Service disconnect installation per code
- Connection torque verification
- Primary and secondary condensate drainage
- Condensate pump where gravity drain unavailable
- Float switch on secondary pan for safety shutdown

Varies by scenario. AC condenser replacement: $5,500–$16,000 depending on equipment tier. AC addition to heating-only home: $7,000–$14,000. R-22 conversion: $5,500–$16,000. Complete system replacement: $10,000–$28,000. Heat pump installation: $6,500–$22,000. Swamp cooler to central AC conversion: $8,000–$14,000.
How long does AC installation take in Kearns?
AC condenser replacement typically 1 day, 4–6 hours. AC addition to heating-only home 1–2 days. R-22 conversion typically 1–2 days. Complete system changeout 1–2 days. Heat pump installation 1 day, 6–8 hours.
Can you add AC to my heating-only Kearns home?
Yes. AC additions to existing heating-only systems are common Kearns service work. The process involves electrical verification, outdoor unit placement, refrigerant lineset routing, evaporator coil installation in existing furnace, condensate drainage, and thermostat upgrade. We assess feasibility and provide installation quotes during in-home estimates.
Should I convert my swamp cooler to central AC?
Depends on preferences and budget. Swamp coolers cost less to operate (no compressor) but provide less comfort during humid weather, require more maintenance (pad replacement, water management), and don’t reduce humidity (in fact, they add humidity to the home). Central AC provides better comfort, lower maintenance, and air filtration capabilities. Conversion cost $8,000–$14,000 typically.
Should I get a heat pump instead of AC?
Worth considering, particularly during system replacement. Heat pumps provide cooling and heating in one system, qualify for substantial tax credits and rebates ($2,000 federal plus up to $8,000 IRA rebates for income-qualified households), and operate well across Salt Lake’s climate range. Dual-fuel systems combine heat pump efficiency with gas backup for severe cold. See our heat pumps page.
My AC uses R-22. Should I convert?
Often yes, particularly for older systems with significant leak history or efficiency degradation. R-22 refrigerant costs $150–$275 per pound (vs. $75–$135 for R-410A), making R-22 service increasingly uneconomic. Conversion to current refrigerant equipment also delivers efficiency gains and uses refrigerants with significantly lower environmental impact.
What size AC do I need?
Manual J load calculation determines proper size based on your specific home characteristics. Performed on-site during installation estimate. The right-sized AC is often smaller than what’s being replaced; oversized equipment short-cycles, dehumidifies poorly, and wears out faster.
