Choosing The Right AC Type For You

Last Updated

October 8, 2025

If you’re like most homeowners in San Antonio, your AC is one of the most important appliances in the house. But when someone mentions “ductless,” “split,” “VRV,” or “packaged,” it can feel like a foreign language. Let’s break it down and look at what Daikin offers so you can feel confident when you talk with Stay Cool’s team.

1. Big Picture: Ducted vs. Ductless

Before diving into specific types, let’s look at two overarching categories:

  • Ducted systems: These use air ducts to deliver conditioned air to different rooms. Common in homes with existing ductwork (central air).

  • Ductless systems: No ductwork indoor units (often mounted on walls or ceilings) are connected by refrigerant lines to an outdoor unit. Great for additions, rooms without ducts, or as supplemental cooling.

Daikin, for example, itself divides many of its product lines by “ductless vs. ducted.” 

2. Types of AC Systems

Here are the main categories you might run into:

Type of AC What It Means When To Choose Them
Split / Multi‑Split (Ductless)  One outdoor unit, one (split) or multiple indoor units, each serving a room For additions, converting a room, spaces without ducts
Unitary / Ducted Split Outdoor unit connected to indoor air handler + duct system Traditional central air homes with ducts
Daikin FIT System A compact, low‑profile outdoor unit that “blows from the side” instead of straight up When outdoor space is tight (e.g., side yards, zero-lot lines)
Daikin VRV / VRF (Variable Refrigerant Volume / Flow) One modular outdoor unit serves many indoor units with variable output Larger homes, mixed-use, or commercial / multi-zone needs

3. What Features Matter 

As you explore options, here are some features you may want to look out for.

Inverter Technology & Efficiency

Many systems, like Daikin’s, use inverter compressors, which let the system vary speed rather than just turning fully on or off. That helps:

  • Maintain a more consistent temperature

  • Reduce energy use

  • Cut noise from frequent “cycling”

Inverter tech often helps with energy savings and quiet operation. 

Refrigerant & Environmental Impact

Newer refrigerants (such as R‑32) have lower global warming potential (GWP). 

Flexibility & Zoning

Particularly with multi-split or VRV systems, you can control different rooms independently—one room cooler, another warmer. 

Space Constraints

Side‑discharge models allow flexibility when your outdoor space is tight. 

4. Why Stay Cool Recommends Daikin

When we at Stay Cool talk with homeowners here in San Antonio, here are the advantages we often highlight:

  1. Climate suitability: The inverter systems handle the hot Texas summers efficiently, while heat pump or ducted systems can provide milder heating.

  2. Quiet operation: Especially when your neighbors and your family don’t want to hear the AC chugging along.

  3. Flexibility: Whether you have one room to cool, a whole home, or an addition without ducts, Daikin covers many scenarios.

  4. Warranty & reputation: Daikin’s brand strength and warranties help give peace of mind (though details vary regionally, always verify).

  5. Space constraints: Many neighborhoods have tight outdoor yard space, and Daikin’s FIT and side-discharge options help in tight spots.

5. Tips for Homeowners 

  • Sizing matters: A properly sized unit will cool best, use energy efficiently, and last longer.

  • Ask about SEER / EER / HSPF ratings: These efficiency numbers help compare systems.

  • Duct condition: If using a ducted system, leaky or poorly sized ducts will hurt performance.

  • Authorized installers: Always use certified installers, especially for Daikin systems, to preserve warranties and ensure correct setup.

  • Maintenance: Clean filters, leak checks, coil cleaning, staying on top of maintenance can extend system life.

Conclusion: Take Your Time and Ask Questions

Choosing the right air conditioner can feel overwhelming with all the technical terms and options out there, but it doesn’t have to be. By understanding the basics, like ducted vs. ductless systems, the benefits of inverter technology, and the importance of proper sizing, you’re already ahead of the curve. Daikin offers a wide range of solutions to fit the unique needs of San Antonio homeowners, whether you’re cooling a single room, an entire house, or dealing with limited outdoor space. And with the expertise of the Stay Cool team, you’ll have guidance every step of the way. Take the time to explore your options, ask questions, and make an informed decision, your comfort (and energy bill) will thank you.
