Choosing the Right System: Central Air vs. Ductless
Not every home cools the same way. We help you choose the system that balances comfort, installation cost, and long-term energy savings.
1. Central Air Conditioning
The Gold Standard for Whole-Home Cooling
For homes with existing ductwork, central air is often the most cost-effective and streamlined choice. It uses a centralized outdoor condenser and an indoor air handler to distribute cool, filtered air evenly through vents in every room.
- Best For: Larger homes, families who want consistent temperatures in every room, and homes with good existing ductwork.
- The SunnyMac Advantage: We size your unit precisely to avoid “short-cycling” (which wastes energy) and inspect your ductwork to ensure you aren’t losing cool air to leaks.
2. Ductless Mini-Splits
Targeted, Ultra-Efficient Comfort
Ductless mini-splits (also known as ductless heat pumps) allow you to cool specific “zones” of your home without the need for bulky ductwork. They consist of an outdoor compressor connected to sleek indoor units mounted on walls or ceilings.
- Best For: Historic homes without ducts, sunrooms, new additions, or families who fight over the thermostat setting.
- Efficiency Bonus: Because there are no ducts to leak air, ductless systems are often 20–30% more efficient than traditional forced-air systems.

Pro Tip: Pairing a new, high-efficiency AC with solar panels is the ultimate way to stabilize your energy costs. You generate the power you need to stay cool, reducing your reliance on the grid.
Understanding AC Installation Costs
We know budget is a major factor. While every home is unique, understanding general market ranges can help you plan with confidence.
Central Air Installation Cost
In 2025–2026, the average cost for a complete central air replacement typically ranges between $5,500 and $14,000+ depending on the unit’s size and efficiency rating (SEER2).
- Factors: Home size (square footage), condition of existing ducts, and efficiency level selected.
Ductless Mini-Split Cost
Ductless systems offer flexibility but costs vary widely by how many “zones” (indoor heads) you need. Single-zone units generally start around $5,000–$7,000, while multi-zone whole-home systems can range from $7,000 to over $14,000.

Frequently Asked Questions About Heating
How long does AC installation take?
Most central air replacements are completed in one day. Installing a new ductless system or a complex central system with ductwork modifications may take 2–3 days. We always provide a clear timeline before starting work.
Do I need to replace my furnace when I get a new AC?
Not always, but it is often recommended. Your AC and furnace share a blower motor; if they are mismatched in age or efficiency, your new AC may not perform to its full potential. We will assess your current furnace and give you an honest recommendation based on its condition.
What is a SEER2 rating?
SEER2 (Seasonal Energy Efficiency Ratio 2) measures how efficiently a unit cools your home. The higher the number, the less energy it uses. Upgrading from an old SEER 10 unit to a modern SEER2 16+ unit can significantly lower your electricity bills.
Does a new AC help with solar energy goals?
Absolutely. A more efficient AC requires less electricity to run. This means your solar system can cover a larger percentage (or all) of your cooling costs, helping you reach energy independence faster.
