Air Conditioner Replacement Cost FAQ
New central AC installations with Naugle Heating and Cooling start at
$4,900. Most homeowners in Lenawee County spend $4,900 to $12,000,
depending on system efficiency, size, features, and installation
details.
We install both Carrier and Lennox central air conditioners, giving you
reliable, energy-efficient options at different price points.
With proper maintenance, most central air conditioners provide 15 to 20
years of reliable service. Efficiency often matters more than age — a
high-SEER2 system can cut energy use by 40% compared to an older 10–12
SEER unit.
- Old 10–12 SEER system: ~$8.40/day to run
- High-efficiency 26 SEER2 system: ~$3.36/day to run
- Savings: about $450 per summer, adding up to thousands over 15 years
- Older systems: Single-stage compressors cycle on and off at full blast, often running 12 hours/day.
- High-efficiency systems: Variable-capacity compressors and ECM motors modulate cooling smoothly, usually holding comfort in 8 hours/day or less — using less energy while improving humidity control.
SEER2 is the updated efficiency rating introduced in 2023. Michigan
requires new systems to be at least 13.4 SEER2, but advanced Carrier and
Lennox systems can reach 20 to 26 SEER2, delivering maximum comfort
while using far less electricity.
- Too large: Short cycles, poor humidity control, wasted energy, and extra wear.
- Too small: Runs constantly but never catches up, leaving rooms hot and humid.
Naugle Heating and Cooling performs professional load calculations on every job so your AC is perfectly matched to your home.
- Single-stage: On/off operation, lowest upfront cost, reliable when sized correctly.
- Two-stage: Runs low most of the time, high only in extreme heat, more efficient, and provides even comfort.
- Variable-capacity: Continuously adjusts in tiny increments, the quietest, most efficient, and best at humidity control.
Replacement often makes sense when:
- The system is around 15–20 years old
- Repairs are stacking up
- Energy bills keep rising
- Comfort is uneven, or the system runs constantly
- Parts: 5 to 10 years (with registration)
- Compressor: 10 years (with registration)
