Heat Cool Cost

FAQ + operating cost calculator

Help homeowners compare comfort, efficiency, and cost.

This MVP gives you 15 sales-ready FAQs plus an operating cost comparison tool for furnaces, air conditioners, and heat pumps. It is built to be embedded in or linked from your quoting workflow.

Static site friendly for Vercel

URL-prefill ready for quoting app integration

Transparent rate assumptions instead of fake live data

Operating cost calculator

Enter the current and proposed equipment details, choose a fuel-rate source, and compare estimated yearly operating cost. This is a planning tool, not a final utility bill.

1. Home and rate source

ZIP code

State

Electric utility

Gas / propane source

Winter indoor temp preference

Summer indoor temp preference

Choose provider presets for a fast estimate, then override the numbers if the homeowner has exact rates from a bill.

Electricity

$0.17

per kWh

Natural gas

$1.10

per therm

Propane

$2.65

per gallon

2. Current system

System type

Heating size

Existing system install year

Cooling size

Existing blower motor assumption

Likely PSC blower motor

Fan operation

Auto On

Primary fuel

AFUE %

SEER2

HSPF2

Dual-fuel changeover temp

35°F • Estimated heat-pump share: 40%

3. Proposed system

System type

Heating size

Proposed blower motor assumption

ECM blower motor

Fan operation

Auto On

Cooling size

House load basis

Uses the proposed system to estimate the home's fictional heating and cooling load.

Primary fuel

AFUE %

SEER2

HSPF2

Dual-fuel changeover temp

30°F • Estimated heat-pump share: 50%

4. Comparison setup

How many proposal options?

Comparison note

Option A anchors the fictional house-load estimate so the baseline and every proposal option are compared against the same target load.

Comparison results

Use this in the home to explain how efficiency, fuel source, and equipment type change the yearly spend.

Fill in the equipment details and rates, then calculate to compare the current system against one to three proposal options.

Important estimate notice: This calculator is intended only as a rough estimating tool for operating cost and potential savings. It was built because there has been a major lack of useful operating-cost tools in the market, and it uses the best data, math, and HVAC theory we have available to estimate something that is honestly very difficult to predict with precision. The output should be treated as an informed estimate, not a guarantee, promise, warranty, or representation of actual future utility bills or savings.

Real-world results can vary materially based on factors that this tool cannot fully know or perfectly model, including but not limited to insulation levels, air leakage, duct design and leakage, humidity patterns, thermostat settings, indoor temperature preferences, occupancy habits, utility tariffs and riders, maintenance levels, equipment commissioning quality, cycling behavior, blower settings, filtration choices, weather volatility, and how the home is actually used after installation.

In other words, this tool is designed to provide the best estimate possible with incomplete information by using scientific theory, historical climate assumptions, utility data, and equipment-performance math. Real-world application has a way of humbling the science and math in this industry. Homeowners should use these results as a planning and comparison aid, not as a guaranteed prediction of future cost or savings.

Integration guide

This app is intentionally static so you can deploy it quickly on Vercel. It already supports URL prefills, which makes it easy to launch from your quoting app.

What to pass in

Homeowner ZIP or state so we can suggest climate hours and utility presets.
Current system type, size, fuel, and efficiencies.
Option A, B, and C system type, size, fuel, and efficiencies when you want side-by-side quote comparison.
Optional exact utility rates if your quoting app already stores them.

Recommended next step for production

Keep this static front end on Vercel, then add a tiny backend endpoint later for real provider lookup and bill-based rate normalization.
If you want true provider-level accuracy, we should add a data pipeline or API instead of claiming “AI found the rates” in the browser.
Once your quoting app is ready, we can wire its existing fields into this calculator with URL params or a signed API payload.

Help homeowners compare comfort, efficiency, and cost.
