![]() ![]() This can be daily, weekly, monthly, annually, etc. The total will be the watts needed for the formula.Īfter that, you need to know how many hours you run the system. If the wattage is not listed, you can figure it out by multiplying the voltage and amperage listed. This will be listed on the owner’s manual for the new system or the company’s website. You also need to know the watts used by the HVAC unit. The rate will be listed in kilowatt-hours (kWh), and the national average is 13 cents. ![]() This will be rated on your electric bill, or you can call your local electric company. The first thing you need to know is how much you pay for electricity. When estimating your annual costs, you need to know (or use averages) several aspects. ![]() Your running costs will vary based on regional temperatures, kWh costs, number of hours or days running, and average ambient temperature in your region. It is also based on the US average kilowatt-hour (kWh) cost of 13 cents. The estimated running costs are based on a standard 90-day operational season for air conditioners. Your costs may be different, depending on the variable such as labor cost, where you purchase the unit, time of year of install, and other factors. Not all units will qualify, and most will also require professional, licensed contractor installation.Īs you will see below, the various models range in cost across all the categories. However, there is a push to extend the rebate program and increase the amounts, which will double the returns (up to $600) through 2026. The requirements and total amounts will vary, but as of this writing, the offer is up to $300. The US government is allowing tax breaks and rebates when you install a new, energy-efficient system. For cost estimates, we will use the average condensing unit size of 2.5 tons.įinally, you also need to account for rebates. The smaller the unit is, obviously, the less output it will have. They also offer various tonnage compatibility, from 1 to 5 tons. While this isn’t the highest SEER rating of an HVAC system, the lows are also not the lowest, giving you a higher overall range. The SEER rating for energy efficiency falls between 13 and 19, depending on the unit. ![]()
