Heco Energy & Ownership Planning

What could your home cost to heat and cool after replacement?

Use this planning model to explore operating-cost differences, then have Heco verify the assumptions against your actual home, utility bills and equipment.

Long-term ownership, not just sticker price

Compare an older gas furnace + AC with a high-efficiency heat-pump scenario

Adjust energy usage and rates to see why the same equipment can produce very different economics in SMUD, Pioneer, Roseville Electric, PG&E and other service areas.

Important: This is an illustrative model—not a quote, bill prediction, rebate determination, equipment recommendation or guaranteed savings. Heco should verify actual bills, utility territory, load, ductwork and final equipment before using a savings estimate in a purchase decision.

Start with your utility context

Adjust the energy example

Use heating/cooling consumption when available instead of the entire household bill. Utility prices vary by season, time, tier and rate plan.

Illustrative annual HVAC energy cost

Before: gas furnace + older AC$1,840/year
After: high-efficiency heat-pump scenario$798/year

$1,042 estimated annual difference

About $87/month averaged over a year

Heating: $1,120 → $438/year. Cooling: $720 → $360/year.

Illustrative 10-year operating-cost difference: $10,420 before rate changes.

Heco verification step

Bring your real bills

Heco can compare recent electric and gas bills with your current system, home conditions and proposed equipment before treating any modeled savings as meaningful.

The model covers estimated HVAC heating/cooling energy only. Other appliances, fixed charges, taxes, solar production, rate changes and household behavior can make the total utility bill very different.

Assumptions and calculation method

Old AC: assumed 10 SEER. New heat-pump cooling: modeled at twice the old cooling efficiency for equal cooling demand. A specific matched system needs its certified ratings; SEER and SEER2 should not be directly mixed.

Old furnace: assumed 80% AFUE. New heat pump: assumed seasonal COP selected above. Weather, defrost, backup heat, sizing, ductwork and installation affect seasonal performance.

Heating electricity (kWh) = heating therms × 100,000 × 0.80 ÷ 3,412.142 ÷ seasonal COP. Each energy quantity is multiplied by the selected price.

The 10-year figure simply multiplies the current modeled annual difference by 10. It does not predict future rates, maintenance, repairs, financing, equipment life or rebates.

Rebates can affect upfront project cost but are separate from energy use. Use the Heco Rebate Center and confirm current program rules before purchase.
