Making the Switch to Geothermal Heating and Cooling
Considering a geothermal system involves more than just picking new equipment; it’s a major home infrastructure project. You need a contractor who understands ground loop installation and proper system sizing. Precision Heating & Cooling has the experience to guide you.
How Geothermal Systems Use the Earth for Comfort
A geothermal system doesn’t create heat by burning fuel. Instead, it moves heat between your home and the ground. This process makes it an incredibly efficient way to provide both heating and air conditioning.
The system has two main parts. The first is a series of pipes buried underground, called a ground loop. The second is a geothermal heat pump unit inside your home, which looks similar to a traditional furnace.
In winter, a fluid circulating through the ground loop absorbs the earth’s steady, low-grade heat and carries it to the indoor unit. The heat pump then concentrates this thermal energy and distributes it as warm air throughout your home. In summer, the process reverses, pulling heat from your house and transferring it into the cooler earth.
Evaluating Your Property for a Geothermal System
The most critical part of a geothermal project is designing and installing the ground loop that fits your property. The amount of land you have, along with its features, determines the best type of loop for your home. We perform a thorough site evaluation to recommend the right solution.
Horizontal Ground Loops
If you have a larger lot with plenty of open space, a horizontal loop is often a practical option. We use an excavator to dig trenches several feet deep. The pipe is then laid in long, parallel lines within these trenches before being carefully backfilled.
This method requires more surface area than other options but is typically less expensive to install because it involves standard excavation. The layout is planned to avoid interference with landscaping, septic systems, and utility lines. The land can be used for lawns or gardens after the installation is complete.
Vertical Ground Loops
For smaller properties in Comstock Park or lots with extensive landscaping, a vertical loop is an excellent solution. This method requires very little surface area. We use a specialized drilling rig to bore several deep holes, typically 150 to 450 feet down.
A pair of pipes with a U-bend at the bottom is inserted into each borehole, which is then filled with a special grout to ensure good thermal conductivity. Though the drilling process makes this a more expensive option upfront, it allows homes on almost any lot size to benefit from geothermal energy.
Pond or Lake Loops
If your property includes a body of water of adequate size and depth, a pond loop can be a very cost-effective choice. This approach involves placing coils of pipe at the bottom of the pond or lake. This eliminates the need for extensive excavation or drilling.
The water provides excellent thermal transfer. We evaluate the water body to ensure it meets the necessary requirements for a successful installation. This provides all the benefits of geothermal with a potentially simpler installation process.
The Geothermal Installation Process
A geothermal installation is a coordinated project with distinct phases. We manage each step to ensure the system is installed correctly for long-term performance. If you are ready to explore your options, you can request a free estimate on a new geothermal system installation from us.
First, we conduct a detailed consultation and site survey. We perform a heat load calculation on your home to determine the exact size of the equipment needed. We then assess your property to design the most effective ground loop configuration.
Next comes the outdoor work of installing the ground loop, which involves either excavation or drilling as planned. Once the loop is in place and the pipes are run into your home, the site is restored. You can expect this part of the process to cause some temporary disruption to your yard.
Inside your home, we install the geothermal heat pump unit. We connect it to the ground loop and to your existing ductwork. If your ductwork needs modifications to handle the airflow from the new system, we address that at this time.
The final step is to fill and purge the ground loop, then start up the system. We perform a complete series of tests and checks to ensure everything is operating according to specifications. We then walk you through the new thermostat and system operation.
Long-Term System Care and Benefits
Once installed, a geothermal system provides consistent and comfortable heating and cooling. The indoor components are housed inside, protected from the elements. Most products include a 10-year parts warranty and a 1-year labor warranty.
Like any HVAC system, your geothermal unit benefits from regular professional maintenance. Our maintenance plan includes two visits per year to inspect and tune up your equipment, ensuring it continues to operate efficiently. Plan members also receive priority service and a 10% discount on any necessary repairs.
Understanding the Investment
A geothermal system is a significant investment in your home. The cost is higher than a traditional furnace and air conditioner because it includes the ground loop installation. However, the operational savings and long system life are key factors to consider.
We provide honest pricing and no-pressure options to help you make an informed decision. For homeowners in West Michigan, financing may be available through Michigan Saves to help manage the initial cost. Precision Heating & Cooling has been serving Kent County since 1994, and our Michigan Mechanical Contractor licence is #7111083.
