Introduction
When a heat wave hits, customers want cool air fast. But simply selling "a mini-split" isn't enough. Choosing the right system depends on the application.
Our R32 single-zone mini-split lineup is available in three performance levels: Centurion (CHW), Heatfinity (PUHW), and Ultima (AUHW). Selecting the right model not only delivers the performance your customer expects but also helps protect your margins by matching the system to the project's actual needs.
Here's a practical guide to help you choose.
Three Models, Three Applications
Centurion, CHW R32 — The Best Value
The CHW R32 is the most affordable option in the lineup without compromising reliability.
It's the ideal choice for:
- budget-conscious projects
- fast installations during peak cooling season
- customers whose primary need is air conditioning
Recommend the CHW when price is the customer's top priority.
Heatfinity, PUHW R32 — The Versatile Mid-Range Choice
The PUHW R32 offers enhanced efficiency and greater comfort.
It's the model most contractors will recommend for everyday residential applications, providing an excellent balance between price and performance.
Recommend the PUHW for the majority of residential projects.
Ultima, AUHW R32 — Premium Cold-Climate Heating Performance
The AUHW R32 delivers the highest heating performance in the lineup, maintaining comfort even during severe winter conditions.
It's the right solution when customers want efficient year-round heating, including:
- replacing electric baseboard heating
- maximizing eligibility for available rebates
- homes located in colder climates
The AUHW is the premium choice for superior winter performance.
Four Questions to Ask Before Making a Recommendation
Before recommending a system, ask these four simple questions.
1. Is the customer's priority cooling only, or cooling and heating?
- Primarily cooling → CHW or PUHW
- Significant winter heating → AUHW
2. What is the customer's budget?
- Limited budget → CHW
- Greater investment for comfort and efficiency → PUHW or AUHW
3. Is the customer planning to apply for rebates?
High-efficiency models such as the AUHW generally offer the best opportunity to qualify for incentive programs.
Always verify current program requirements before making recommendations.
4. How long does the customer expect to own the home?
The longer the ownership period, the more the increased efficiency of the PUHW or AUHW pays for itself through lower operating costs.
Quick Comparison
| Model | Positioning | Best Recommended For |
|---|---|---|
| CHW R32 | Best value | Budget-conscious projects, cooling-focused applications, quick installations |

| AUHW R32 | Premium heating efficiency | Cold climates, heating-focused applications, rebate-eligible projects |
Don't Oversize the System
Regardless of which model you choose, proper sizing is always more important than choosing a larger unit.
An oversized heat pump can:
- short cycle
- provide poor dehumidification
- wear out more quickly
- reduce overall efficiency
Always perform a proper heat load calculation rather than sizing solely by square footage.
For Specialized Applications
Need something other than a wall-mounted indoor unit?
Specialty indoor units—including cassette, concealed ducted, and console models—from our multi-zone lineup can also be installed in single-zone applications. They're an excellent solution when a wall-mounted unit isn't the best fit for the space.
