Falling in love with a home—only to realize it doesn’t have central air—can be a bit of a shock, especially during a Maryland summer. But don’t walk away just yet. There are several ways to cool your future home, from traditional central air systems to modern ductless solutions. Understanding your options, installation needs, and average costs can help you make the right decision before or after you buy.
Why Some Homes Don’t Have Central Air
Many older homes, especially those built before the 1970s, were constructed without central HVAC systems. These homes may have relied on window units or baseboard heat. Installing a new system now depends on whether ductwork is already in place—or if you’ll need a ductless alternative.
Option 1: Installing Central Air Conditioning
If the home already has ductwork for a forced-air heating system, adding central air can be relatively straightforward. If not, it becomes a more complex and expensive project.
What it involves:
- Installing a central air unit outside
- Running or upgrading ductwork through the walls, ceilings, or floors
- Adding supply vents and return registers
- Connecting to your electrical system and thermostat
Average cost in Maryland:
- With existing ductwork: $4,500 to $7,500
- Without ductwork: $8,000 to $15,000 or more, depending on the home’s size and layout
Homes without ductwork may also require drywall repairs or updates to handle the installation.
Option 2: Installing a Ductless Mini-Split System
Ductless mini-split systems offer an efficient alternative, especially for homes where installing ductwork isn’t practical.
What it involves:
- An outdoor condenser connected to indoor air handling units
- Wall-mounted units installed in key areas of the home
- A small hole drilled through the wall to connect refrigerant and power lines
Benefits:
- Zoned temperature control (each unit can be operated independently)
- Energy-efficient performance
- Easier installation with minimal disruption
Average cost in Maryland:
- Single-zone system (cooling one area): $3,000 to $5,000
- Multi-zone system (cooling the whole home): $7,000 to $15,000+
Key Considerations
Whether you go with central air or mini-splits, here are a few important things to keep in mind:
- Your home’s electrical system must be able to support the new equipment. Some older homes may require a panel upgrade.
- The layout and size of your home will affect both your comfort and cost.
- If you’re buying a home to renovate, incorporating central air during remodeling may make the process easier.
