What Does AC Installation Include?
Professional air conditioning installation is a complex process requiring technical expertise and precision. A complete installation includes:
- Cooling Load Calculations: Using Manual J methodology to determine the exact cooling capacity your home needs
- System Design: Planning equipment placement, refrigerant line routing, and airflow optimization
- Equipment Selection: Choosing the right AC size, efficiency level, and brand for your needs and budget
- Outdoor Unit Installation: Setting and leveling the condenser unit on a proper pad or platform
- Indoor Coil Installation: Installing or replacing the evaporator coil in your existing ductwork
- Refrigerant Line Set: Running properly sized copper refrigerant lines between indoor and outdoor units
- Electrical Connections: Installing dedicated circuits, disconnect boxes, and proper wiring to code
- Condensate Drain: Installing proper drainage for moisture removed from indoor air
- Thermostat Installation: Wiring and programming new thermostats compatible with your system
- System Startup: Evacuating lines, charging refrigerant to manufacturer specifications, and testing all functions
- Final Testing: Verifying proper airflow, temperature drop, and efficient operation
- Permit and Inspection: Obtaining required permits and scheduling code compliance inspections
Signs You Need a New Air Conditioning System
If you're experiencing these issues, it's time to consider AC installation rather than continued repairs:
- AC Over 12-15 Years Old: Modern systems are significantly more efficient than older units
- Uses R-22 Refrigerant: R-22 (Freon) is discontinued and increasingly expensive to replace
- Frequent Repairs: Multiple repair bills in recent years add up to replacement cost
- High Energy Bills: Cooling costs have increased despite similar usage patterns
- Inadequate Cooling: System can't keep up during hot weather or creates uneven temperatures
- Currently Using Window Units: Ready to upgrade to quiet, efficient central air conditioning
- Home Addition: You've added square footage and your current system is undersized
- Major Component Failure: Compressor or other expensive components have failed on an aging system
- Humidity Problems: Home feels muggy even when AC is running
💡 SEER Ratings Matter
SEER (Seasonal Energy Efficiency Ratio) measures AC efficiency. Higher SEER means lower operating costs. Modern AC systems range from 14 SEER (minimum) to 25+ SEER (ultra-efficient). A 16 SEER system uses about 13% less energy than 14 SEER. For Michigan's climate, 16-18 SEER offers the best balance of efficiency and affordability.

- Ductless Mini-Split (multi-zone): $5,000 - $12,000 (2-5 zones)
- Coil Replacement (if needed): $800 - $1,800 additional
- Line Set Replacement: $500 - $1,500 (depending on distance)
- Electrical Upgrades: $300 - $1,000 (if panel upgrades needed)
- Permits and Inspections: $100 - $300
Note: Installing AC for the first time (no existing system) costs more due to additional electrical work, thermostat installation, and potential ductwork modifications. Budget an additional $1,000-$2,500 for first-time installations.
Types of AC Systems for Ann Arbor Homes
Different cooling systems work better for different situations:
- Central Air Conditioning: Most common for homes with existing ductwork. Quiet, efficient, cools entire home evenly. Best for: Most single-family homes with forced-air heating.
- Ductless Mini-Split Systems: No ductwork needed. Individual zones have separate controls. Best for: Homes without ducts, additions, converted garages, multi-generational homes wanting zone control.
- Heat Pump Systems: Provides both heating and cooling in one system. Ultra-efficient. Best for: New construction, homes without natural gas, energy-conscious homeowners.
- Packaged AC Units: All components in one outdoor unit. Best for: Homes with limited indoor space, mobile homes, some commercial applications.
Why Proper Installation is Critical
Even the best air conditioning equipment will fail to perform if improperly installed. Poor AC installation causes:
- Up to 30% reduction in cooling efficiency and higher energy bills
- Shortened equipment lifespan (10 years instead of 15-20)
- Inconsistent temperatures and comfort problems
- Excessive humidity and muggy indoor conditions
- Voided manufacturer warranties due to improper startup
- Refrigerant leaks from improper line work
- Noisy operation from unbalanced airflow
Best Time to Install Air Conditioning
The ideal time for AC installation in Ann Arbor is spring (April-May) or fall (September-October). Benefits of off-season installation include:
- Lower prices due to reduced demand
- Better contractor availability and scheduling flexibility
- More time for contractors to focus on quality installation
- System ready to go before extreme temperatures hit
- Easier to test system performance in moderate weather
Energy Rebates and Tax Credits
Installing a high-efficiency AC system may qualify for financial incentives:
- Federal Tax Credits: Up to $300 for qualified ENERGY STAR systems (check current year requirements)
- DTE Energy Rebates: $250-$500 for high-efficiency central AC (14.5+ SEER)
- Consumers Energy Rebates: Similar rebates for qualifying systems
- Manufacturer Rebates: Seasonal promotions offering $300-$1,000 off select models
Your contractor can help identify available rebates and handle paperwork.
