• Summer: Works like an AC, pulling heat out of your home and releasing it outdoors.
• Winter: Reverses operation, extracting heat from outdoor air and transferring it indoors.

• SEER2: Cooling efficiency (higher = less electricity in summer).
• HSPF2: Heating efficiency (higher = less electricity in winter).

In Ohio, new systems must be at least 14.3 SEER2. Lennox heat pumps reach up to 23 SEER2 and 10.5 HSPF2 — among the most efficient available.

When outdoor temps drop below about 30°F, pairing with a gas furnace in a dual-fuel system ensures reliable comfort all winter long.

• Furnace: Burns fuel, delivers air 110–120°F (feels hot immediately).
• Heat pump: Typically delivers ~90°F air. Since your body is ~98.6°F, it may feel cool on your skin but still heats effectively.

What this means:

• When gas is cheap: Use the heat pump as AC in summer, let the furnace handle coldest days.
• When gas spikes: Heat pump saves money. In dual-fuel setups, heat with the pump down to ~30°F, then switch to furnace only when needed.

• The system is 10+ years old and poorly maintained
• Repairs are stacking up
• Energy bills keep rising
• Comfort is uneven

• Parts: 5–10 years (with registration)
• Compressor: 10 years (with registration)

• Ohio utility rebates (AEP Ohio, local co-ops)
• Seasonal manufacturer rebates
