One of the most energy efficient ways to heat and cool your home is one that many homeowners have never heard of before: geothermal.
Lower heating and cooling bills
Uses significantly less energy than other HVAC systems
Less maintenance & longer lifespan
Quiet, all electric operation
Heating and cooling in a single unit
Save thousands with a no-cap 30% federal tax credit
Princeton installs geothermal heat pumps (also called ground source heat pumps) in homes throughout central New Jersey and southeastern Pennsylvania. Talk to our heating and cooling specialists today!
What is Geothermal Energy and How Does Geothermal Work?
Geothermal energy is a renewable energy source from the Earth. Outdoor temperatures fluctuate with the changing seasons, but underground temperatures don’t. Four to six feet below the earth’s surface, it might surprise you to learn that temperatures remain relatively constant year-round.
A geothermal heating and cooling system capitalizes on these constant temperatures to heat and cool your home. In winter, a series of underground pipes called a “ground loop” take heat from the earth and carry it indoors to warm your house. In summer, the system reverses, taking heat from inside your home and depositing it into the ground to keep you cool.
Geothermal systems are a kind of heat pump, related to air source ducted heat pumps or ductless mini-splits. But instead of absorbing heat from the air, geothermal heat pumps absorb heat from the ground.
The Advantages of Geothermal Energy
- Geothermal systems are over five times more efficient in heating and more than twice as efficient in cooling as traditional HVAC systems. This kind of energy savings can lead to dramatically lower energy costs for homeowners.
- Geothermal systems are practically maintenance free. The buried loop will last for generations. The unit’s fan, compressor, and pump is housed indoors, protected from the weather and contamination.
- Like other heat pumps, geothermal systems are environmentally friendly and run entirely on electricity—they emit no greenhouse gasses. For homeowners interested in home electrification upgrades, geothermal is a great option, and if you have solar panels installed, you can run your heating and cooling for free!
- Some geothermal heat pumps can provide all of your home’s hot water needs too. An option called a hot water assist can be added to most geothermal heat pumps. It will provide significant savings by heating water before it enters your hot water tank.
- Heat pumps have a much longer life expectancy than other heating and cooling systems—20+ years for the indoor heat pump unit itself and 50+ years for the buried ground loop system.
- Because much of the equipment is underground, there are no outdoor components to make noise, making them quiet for you as well as your neighbors.
How are Geothermal Heat Pump Systems Installed?
There are two main components to a geothermal system: the indoor heat pump unit and the outdoor underground loop system.
Most loops are trenched horizontally in areas adjacent to the building. However, where adequate land is not available, loops are vertically bored. Any area near a home or business with appropriate soil conditions and adequate square footage will work. Loop lengths and depths may vary with loop types, soil conditions, and the layout of your property.
Qualify for a 30% Federal Tax Credit with Geothermal Installation from Princeton Air
Best of all, geothermal heat pumps qualify for the same 30% tax credit that solar panels do. This tax credit has no upper limit—you simply claim a federal tax credit equal to 30% of your geothermal installation costs for the year that you installed your new system. You can also roll over any remaining balance to future years.
While geothermal HVAC systems cost more up front compared to many other heating and cooling systems, they last significantly longer, require little maintenance, and can drastically reduce your monthly energy bills. Plus, with the federal tax credit, you can reduce your installation costs by thousands!
