When evaluating a geothermal heat pump, it's important to look at all the benefits it provides:
Geothermal systems will reduce monthly heating and cooling bills up to 70% over traditional HVAC systems. With geothermal, you do not have to worry about the volatile swings associated with fossil fuel costs.
The average life expectancy of a geothermal system is nearly 25 years compared to the 13 year average life expectancy of traditional furnaces and air conditioners. The ground loop powering the geothermal system lasts 100 years plus!
Geothermal systems have less maintenance costs when compared to traditional HVAC. This is due to geothermal equipment being kept indoors and not outside, exposed to the elements. Additionally, geothermal systems have fewer moving parts, which makes for less opportunity for a malfunction.
With geothermal, home and building owners will experience 25% to 40% savings on hot water costs. How? An item within the unit, called the desuperheater, captures waste heat during operation and transfers it into the domestic hot water supply, providing hot water assist and enhancing the operation of the unit. Traditional HVAC does not have this option.
Studies show that homes with energy-efficient features sell for as much as 40% more than expected. So, even if you aren't planning on staying in your home for the lifetime of the system, you can get more money for your home if it has a geothermal system in it, as opposed to an oil or gas furnace. Realtors also say homes with geothermal sell faster than homes without.
Geothermal systems are the safest HVAC system available. Unlike gas, oil, or propane furnaces, geothermal does not rely on fossil fuels at all. Because of this, there is NO combustion or harmful fuels, which removes the potential of carbon monoxide poisoning, oil and gas leaks, or fires.
When comparing geothermal heating, cooling, and hot water systems to traditional HVAC systems, it's important to note that the comparison is not apples to apples – it's more of an apples to oranges comparison. What may appear at first glance as a 'good deal' on a traditional HVAC system may not be the most environmental or economical choice.
