Best Heater and Air Conditioner Combo Wall Unit

Here is a comparison of the three best choices of heater air conditioner combo wall units: Ductless Mini-Split Systems, Through-the-Wall Units, and Window Units, including their available capacities, pros, cons, and approximate costs. Please note that costs can vary based on brand, model, location, and other factors.

Ductless Mini-Split Systems

• Cooling Capacity: Typically ranges from around 6,000 BTUs to 60,000 BTUs or more, depending on the model and brand.
• Heating Capacity: The heating capacity usually matches the cooling capacity, so it also ranges from around 6,000 BTUs to 60,000 BTUs.
• Pros:
  • Energy Efficiency: Ductless mini-splits are highly energy-efficient due to their inverter-driven compressors and lack of ductwork, leading to potential energy savings on heating and cooling bills.
  • Zoning: They offer individual temperature control in different rooms or zones, allowing for personalized comfort and energy optimization.
  • Quiet Operation: The indoor air handler is usually quiet, providing a peaceful environment.
  • Easy Installation: They require minimal invasive installation compared to ducted systems, making them ideal for retrofitting in homes without existing ductwork.
  • Aesthetics: The indoor unit is mounted on the wall or ceiling and can blend seamlessly with room decor.
• Cons:
  • Higher Initial Cost: Ductless mini-splits tend to have a higher upfront cost compared to through-the-wall and window units.
  • Professional Installation: While installation is easier than ducted systems, it still requires professional expertise, which adds to the initial cost.
  • Outdoor Unit: The outdoor compressor unit may take up some space and can be visible, which may not be appealing to some homeowners.
  • Cost (Unit + Installation): The cost of a ductless mini-split system can range from $1,500 to $4,000 per indoor unit, depending on capacity and brand. Installation costs typically range from $1,500 to $4,000 per unit as well.

Through-the-Wall Units

• Cooling Capacity: Commonly available in the range of 5,000 BTUs to 18,000 BTUs for residential models.
• Heating Capacity: Through-the-wall units often come with electric resistance heating, and the heating capacity is generally the same as the cooling capacity, ranging from 5,000 BTUs to 18,000 BTUs.
• Pros:
  • Affordable: Through-the-wall units are generally more affordable upfront compared to ductless mini-splits.
  • Simplicity: These units are relatively easy to install, and they don’t require ductwork.
• Cons:
  • Limited Zoning: Through-the-wall units are typically designed for single-room use, so they don’t offer the zoning capabilities of ductless mini-splits.
  • Less Energy Efficient: They may be less energy-efficient than mini-splits, especially if you have multiple units for different rooms.
  • Appearance: They can be somewhat obtrusive and may not blend as seamlessly with the room decor as ductless systems.
  • Cost (Unit + Installation): The cost of through-the-wall units can vary depending on capacity and features but generally ranges from $400 to $1,500 per unit. Installation costs are relatively lower, typically ranging from $500 to $1,000 per unit

Window Units

• Cooling Capacity: Available in various sizes, typically ranging from 5,000 BTUs to 24,000 BTUs for residential units.
• Heating Capacity: While some window units have heating capabilities, they are generally less common and often not as powerful as the cooling capacity. Heating capacity for window units may range from 3,000 BTUs to 12,000 BTUs.
• Pros:
  • Affordable: Window units are the most budget-friendly option among the three types.
  • Easy Installation: They are easy to install in a standard window opening, and some models may not require professional installation.
  • Portability: They can be easily removed and stored when not in use.
• Cons:
  • Limited Cooling and Heating: Window units are usually designed for cooling purposes primarily, and while some models offer heating capabilities, they might not be as efficient as dedicated heating systems.
  • Single-Room Use: Similar to through-the-wall units, window units are generally suitable for cooling/heating single rooms and might not be ideal for whole-house solutions.
  • Window Space Obstruction: They obstruct the window view and limit natural light.
  • Cost (Unit + Installation): The cost of window units varies based on capacity and features, ranging from $100 to $800 per unit. Installation is often DIY-friendly, but if professional installation is needed, it can add around $150 to $300 to the total cost.

Note: It’s important to choose the appropriate BTU capacity for the space you intend to cool or heat. An undersized unit may struggle to provide adequate comfort, while an oversized unit may lead to inefficient operation and higher energy costs. For accurate sizing, you should consult with an HVAC professional who can do a load calculation based on the specific characteristics of your home or space.
