Unlock clean, renewable energy with Geo! WaterFurnace geothermal systems offer an infinite source of free power, with a lifespan of 20-25 years.

Financial Case For A Geothermal System

If you're shopping for new HVAC equipment, it's probably because your existing equipment is nearing the end of its useful life or you're building a new house. Both scenarios require some level of investment.

What's the minimum you'd be happy with in your home? If you're considering geothermal it's very likely that efficiency is important to you. If the minimum you'd accept is a 16 SEER air conditioner paired with a 92 AFUE furnace, it makes sense to use that cost as a starting point for analysis because it represents the minimum amount of money you can spend and still be comfortable (literally).

Costs for a 16 SEER air conditioner and a 92 AFUE furnace can vary greatly—but it can reach $13,000 in many areas. Again, prices vary greatly based on several factors (geography, ground composition, size of home, equipment chosen, etc.), but let's assume the cost to install a geothermal heat pump in your area is $25,000. There's currently a 30% US federal tax credit, decreasing each year through 2034. That's $7,500 as a credit on your taxes, not just a deduction. The initial cost difference between an ordinary system and a geothermal system is just $5,500. Your area may also have other additional incentives that won't be factored in for this calculation.

Fact

The useful life of the underground energy collector can be more than 100 years and won't need to be replaced at the end of the 25-year life of the indoor heat pump. This means the upgrade costs for the next system will only be for the indoor equipment and, therefore, will be much cheaper.
