Buying Guide
What to consider when choosing an R-454B system
- System type: Decide between a complete split system (condenser + indoor unit) or an evaporator coil to upgrade an existing setup.
- Capacity: Match tonnage to your home’s cooling load. Larger homes may need 3–5 ton units, while smaller spaces can use 2.5 ton models.
- Efficiency: Look for SEER2 ratings around 14.3 for strong efficiency without excessive upfront costs.
- Refrigerant compatibility: R-454B is the standard in these products; ensure all components are designed for this refrigerant.
- Installation considerations: Some products require compatible indoor units or regional availability constraints.
- Space and zoning: Multi-zone setups or limited-installation units can affect choice, especially for mobile homes or tight closets.
Availability and compatibility tips
- Check compatibility with existing ducts or indoor air handlers before upgrading a single component.
