❓ Geothermal FAQ – Answers from Courtesy Heating and Cooling

What is a geothermal system?
A geothermal system uses the steady temperature underground to heat your home in the winter and cool it in the summer. It’s like using the earth’s natural energy to stay comfortable all year long.

Is geothermal heating and cooling really worth it?
Yes! Geothermal systems cost more to install upfront, but they save you money over time. Most homeowners see much lower energy bills and fewer repair costs. Plus, the system lasts longer than regular heating and cooling units.

How long does a geothermal system last?
The underground loop can last 50 years or more. The indoor parts of the system usually last 20–25 years, which is much longer than a typical furnace or AC.

Can geothermal systems work in New Hampshire?
Absolutely. Geothermal works well in New Hampshire, including Exeter and nearby towns. Even in cold winters, the ground stays warm enough to keep your home comfortable.

Does geothermal heating and cooling help the environment?
Yes. It uses less electricity, creates fewer greenhouse gases, and doesn’t rely on oil or gas. It’s one of the cleanest ways to heat and cool your home.

How much space do I need for a geothermal system?
You don’t need a huge yard, but it depends on the size of your home and the type of system. We’ll check your property and help you choose the best setup.

Is financing or a rebate available?
In many cases, yes. There are federal tax credits, energy rebates, and financing plans that can make going geothermal more affordable. We can help you explore your options.
