Energy Cost Calculator
The Energy Cost Calculator is designed to help users estimate the electricity consumption costs associated with operating HVAC systems or other electrical appliances. By inputting the appliance's power consumption (in Watts) or its efficiency rating (like SEER, EER, COP, or AFUE for electric heat) along with the operating load (BTU/hr), hours of use, and local electricity rate (cost per kWh), this tool can provide daily, monthly, and annual cost estimates. It's useful for budgeting, comparing the operational costs of different units, or understanding the financial impact of usage patterns.
Tips for Reducing HVAC Energy Costs: HVAC systems are often the largest energy consumers in a building. To reduce costs: ensure regular maintenance (clean filters/coils), use programmable/smart thermostats, ensure proper insulation and air sealing, use fans to supplement cooling, manage sunlight with window coverings, and upgrade to high-efficiency equipment when replacing systems.
This calculator provides an estimate based on average inputs. Actual energy consumption and costs can vary significantly due to weather conditions, thermostat settings, equipment condition, part-load performance, and fluctuating electricity rates (e.g., time-of-use pricing). This calculator does not account for fuel costs (e.g., natural gas, propane).
