Buying Guide
What size is right for a 3.5 ton system? Ensure the outdoor condenser or air handler matches the 3.5-ton capacity and that refrigerant compatibility is current. For coils, choose models rated for 1.5–3.5 ton installations if you plan to scale or expand later. Consider climate and efficiency, looking for SEER and compatibility with modern refrigerants such as R-454B. Assess installation requirements, ductwork compatibility, and space constraints for a packaged heat pump. When pairing components, prioritize airflow efficiency and corrosion resistance in harsh environments.
Key purchase considerations
- System type: packaged heat pump vs. split system, depending on space and installation.
- Capacity: confirm 3.5 tons aligns with house size and climate load.
- Efficiency: look for higher SEER ratings and refrigerant compatibility.
- Installation: verify cabinet accessibility, duct compatibility, and serviceability.
- Future-proofing: coils that support current refrigerants and potential upgrades.
