HeatMath provides general information and estimates to help homeowners understand heating and cooling options. It is not professional engineering, electrical, tax or financial advice.
- Calculators use simplified, standard methods. They are not a substitute for an ACCA Manual J load calculation or an on-site assessment.
- Prices are typical US ranges from published cost surveys and can differ significantly in your area.
- Tax credits and rebates change often. Confirm eligibility with the program administrator, the IRS or a tax professional.
- Safety: heating equipment involves electricity, refrigerant, combustion gases and carbon monoxide. Repairs beyond simple owner maintenance should be done by licensed professionals.
