Frequently Asked Questions

• What SEER2 rating should I choose for a heat pump with backup heat strip in my climate?

  In warm or mixed climates, 15-18 SEER2 helps cut cooling costs. In mild regions, 14.3-15 SEER2 offers strong value. Colder zones benefit from higher SEER2/HSPF2.

• Which refrigerant (R-32, R-410A, or R-454B) is best for replacement compatibility and future regulations?

  R‑410A matches many existing systems today. R‑32 and R‑454B are lower‑GWP choices aligned with upcoming standards. Choose based on local code, availability, and equipment match.

• How do I size the system tonnage (1.5-5 tons) for my home’s square footage and insulation?

  Have a Manual J load calculation completed. As a rough guide, well‑insulated homes often need about 1 ton per 600-1,000 sq ft, but loads vary by climate and envelope.

• What cabinet width options are available and how do they affect air handler fitment?

  Models come in multiple cabinet widths to match common duct and plenum sizes. Confirm the listed width (often around 14-24.5 inches) for a proper, low‑leak install.

• Is professional installation required for split heat pump systems with electric heat strips?

  Yes. A licensed HVAC pro must handle refrigerant piping, evacuation, charging, wiring, and startup to ensure safety, efficiency, and warranty compliance.

• How does a backup heat strip operate with the heat pump in colder temperatures?

  The strip energizes when outdoor temps drop below set balance points, during defrost, or on Emergency Heat, maintaining comfort when heat pump output falls.

• Are there differences in operating costs between 14.3 vs 18 SEER2 systems?

  Yes. Higher SEER2 cuts cooling kWh and often pairs with better HSPF2 for heating savings. Balance upfront cost against expected utility savings in your climate.

• Can these systems be used in light commercial applications?

  Yes. They’re suitable for small offices or retail suites within capacity limits. Verify electrical service, ventilation, and controls meet code and usage needs.

• Do I need a specific thermostat to control the heat pump and heat strip?

  Use a heat pump-compatible thermostat with auxiliary heat control. Many programmable and smart stats support staging for efficient strip operation.

• What size heat strip (kW) should I choose?

  Selection depends on climate, load, and breaker capacity. Common choices scale with tonnage; your installer will size the kW to meet design heat on the coldest day.
