Quick Price Snapshot
New central air conditioner installations typically start around $3,495. Most homeowners in Calhoun County, Michigan, spend between $3,495 and $12,000+, depending on system efficiency, size, features, and installation details.
When Michigan summers bring heat and high humidity, the right central AC system makes all the difference. At Eric Dale Heating and Air Conditioning, we don’t just install air conditioners — we custom-fit central air conditioning to your home with professional load calculations. From insulation factors to duct design to rooms that face the sun, every detail is factored in so your system runs efficiently, quietly, and reliably for years.
How much does a new air conditioner cost in Calhoun County?
A professionally installed central AC system typically ranges from $3,495 to $12,000, depending on system size, efficiency rating, and features. High-efficiency systems cost more upfront, but in Michigan — where summer power rates can hit 20¢/kWh — the long-term savings on energy bills often make them the smarter choice.
How long does a central AC last?
With proper maintenance, most central air conditioners provide 15–20 years of reliable service. Over that time, efficiency matters more than age. A high-SEER2 system can cut energy use by 40% compared to an older 10–12 SEER unit. At Michigan’s rates, that can save $300+ every summer, adding up to $5,000–$7,000 or more over 15 years — especially as electricity prices continue to climb.
How much can a high-efficiency AC save in Michigan?
In a well-insulated 1,800 sq ft home with a 2-ton system, the difference between an older 10–12 SEER unit and a 26 SEER2 variable-capacity system is clear. Older systems may cost $8.40/day to run, while a modern high-efficiency system can cool the same space for about $3.36/day. That’s a savings of roughly $450 every summer. Over 15 years, as electricity rates continue to rise, those savings compound into thousands of dollars.
Savings Example: Michigan 1,800 sq ft Home
Assumptions:
- 1,800 sq ft, well insulated
- 2-ton central AC
- Old 10–12 SEER, ~3.5 kW, ~12 hrs/day
- High-efficiency 26 SEER2 variable-capacity system, ~40% less draw, ~8 hrs/day
- Summer power: $0.20/kWh
- Cooling season: 90 days/year
Daily Costs
- Old system: 42 kWh → $8.40/day
- 26 SEER2 variable: 16.8 kWh → $3.36/day
- Daily savings: $5.04
Seasonal Savings
$5.04/day × 90 days = $454 per summer
15-Year Savings
- If electricity rates never changed: ≈ $6,804
- With 4% yearly increases (typical utility hike): ≈ $9,083
- With 8% yearly increases (aggressive hikes already proposed in Michigan): ≈ $12,316
Takeaway: Every year, the same kilowatt-hour costs more. That’s why a high-efficiency central AC isn’t just about today’s bill — it’s protection against tomorrow’s rates.
Note: These numbers are estimates based on a typical 1,800 sq ft Michigan home. Actual results will vary with home size, insulation, ductwork, and weather.
Why does a high-efficiency AC run fewer hours?
Older systems use PSC blower motors and single-stage compressors that cycle on and off at full blast. They often need 12 hours a day in Michigan summers to keep up.
High-efficiency systems use ECM fan motors and variable-speed compressors. Instead of blasting at full capacity, they modulate output continuously — adding only the exact amount of cooling needed to match the desired temperature. That means steadier temps, better humidity control, and far less wasted energy. In most homes, they hold comfort in about 8 hours or less per day, using significantly less power every hour they run.
What is SEER2, and why does it matter?
SEER2 is the updated efficiency rating for air conditioners, introduced in 2023. It measures real-world performance, including airflow resistance from ductwork. Michigan requires new systems to meet at least 13.4 SEER2, but high-efficiency systems can reach 20–26 SEER2.
Only variable-capacity systems achieve the highest SEER2 ratings, such as 26. These systems adjust cooling output continuously, so they deliver maximum comfort while using far less electricity — a major advantage when summer rates can hit 20¢/kWh and keep climbing.
What happens if my AC is too large or too small?
An air conditioner that’s not the right size for your home will cost more to run and leave you less comfortable.
- Too large: The system cools the air too quickly, then shuts off. That short cycling causes uneven temps, poor humidity control, higher wear, and wasted energy.
- Too small: The system runs constantly but never quite catches up, leaving rooms hot and humid on summer afternoons.
That’s why the experts at Eric Dale Heating and Air Conditioning don’t do guesswork. We perform full load calculations before every installation. We look at insulation levels, duct design, ceiling height, and even how many rooms face the sun. The result is a system that’s custom-fit to your home — delivering the right comfort at the right efficiency for the next 15–20 years.
What’s the difference between single-stage, two-stage, and variable-capacity central AC?
Single-Stage Central AC
A single-stage system runs either full on or off. It’s the simplest, most reliable design and usually has the lowest upfront cost, which makes it a good fit for smaller or well-insulated homes and for homeowners on a tight budget. Single-stage systems can use more energy than staged or variable systems in heavy-duty climates, but when matched correctly to the home via proper load calculations, they deliver dependable cooling without complexity.
Two-Stage Central AC
Operates at two levels: low for most of the day and high only when needed. Many two-stage systems also use ECM fan motors, giving them smoother airflow and better efficiency than older designs. The longer run times at lower power reduce energy use, improve humidity control, and create more consistent comfort across rooms. A strong middle ground between upfront investment and operating savings.
Variable-Capacity Central AC
The most advanced option. Variable-capacity systems use compressors and ECM fan motors that adjust output in tiny increments. Instead of cycling on and off, they deliver only the cooling your home actually needs at any given moment. A 26 SEER2 variable-capacity system can cut energy use by up to 40% compared to a 16 SEER2 single-stage unit — savings that compound year after year as Michigan electricity rates continue to rise.
Each system type has its place. The key is choosing the one that matches your home, budget, and comfort goals.
Should I repair or replace my old AC?
Replacement makes sense when a system is old, failing, or costing more to operate than a new high-efficiency unit would save — but a well-sized single-stage replacement can be the right, cost-effective choice for many homes.
What warranties come with new Lennox air conditioners?
As a Lennox Premier Dealer, we provide access to strong Lennox warranties, commonly:
- 5-year parts coverage standard, extended to 10 years with registration
- 10 years compressor coverage with registration
Coverage details vary by model and require proper product registration to receive the full term.
Do I need new ductwork?
Not usually. Many Calhoun County homes benefit from duct sealing or return upgrades, but full duct replacement is rarely required. We test airflow and static pressure before recommending any changes.
Are rebates available in Michigan?
Yes. Homeowners may qualify for seasonal manufacturer rebates and utility rebates (through Consumers Energy or DTE). These can take hundreds off the cost of a new central AC. We identify and apply eligible savings at installation so you don’t leave money on the table.
Do you offer financing?
Yes. Financing options are available (with approved credit) to spread out payments. This helps homeowners take advantage of high-efficiency systems now while controlling monthly budgets.
How long does installation take?
Most central AC replacements in Calhoun County are completed in one day. Projects that include duct modifications, venting updates, or code upgrades can take longer.
