What Is Geothermal Heating & Cooling?
A geothermal heat pump, also called a ground-source heat pump, heats and cools your home by transferring heat between the building and the earth. Underground temperatures remain much more consistent throughout the year than outdoor air temperatures, giving the system a stable source for heat exchange. The same system can provide heating and cooling without relying on combustion to generate heat.
Our Geothermal HVAC Services in Watertown
Geothermal systems combine underground loops, heat pump equipment, controls, ductwork, and other components into one complete heating and cooling system. Carew provides geothermal heating and cooling services in Watertown to help homeowners install new equipment, address system problems, and keep existing systems operating reliably.
Geothermal Installation
A successful geothermal heat pump installation starts with evaluating the home, property, heating and cooling loads, and available space for the ground-loop system. Carew can help determine the appropriate geothermal equipment and system configuration for your property and complete the HVAC installation.
Geothermal Replacement
The underground loop of a geothermal system can remain usable much longer than the indoor heat pump equipment. If an aging geothermal unit becomes inefficient, unreliable, or increasingly expensive to repair, Carew can evaluate the existing system and determine the right replacement approach.
Geothermal Repair
Reduced heating or cooling, unusual noises, frequent cycling, inconsistent temperatures, or unexpectedly high energy use can indicate a geothermal system problem. Carew provides geothermal HVAC repair in Watertown to diagnose issues involving the heat pump, controls, circulation, airflow, or other system components and recommend the appropriate repair.
Geothermal Maintenance
Routine geothermal maintenance helps keep the heat pump, air filter, blower, controls, ductwork, and other accessible components operating as intended. Regular service also gives a technician an opportunity to identify developing problems before they interfere with heating or cooling performance.
24-Hour Emergency Geothermal HVAC Repair in Watertown
A geothermal system provides both heating and cooling, so a major breakdown can affect home comfort in any season. Carew provides 24/7 emergency HVAC support when an urgent geothermal heating or cooling problem can’t wait until normal business hours. Call our team for help if your system stops operating when you need it most.
Geothermal Heat Pump vs. Air-Source Heat Pump
Both geothermal and air-source heat pumps transfer heat rather than creating it through combustion, and both can provide heating and cooling from one system. The biggest difference is where the heat comes from. Air-source systems exchange heat with the outdoor air, while geothermal systems use the more consistent temperatures beneath the ground.
Air-Sourced Heat Pump
Geothermal Heat Pump
Heat Source
Outdoor air
Ground below the property
Cold Weather Performance
Performance is affected by changing outdoor temperatures
Uses relatively stable underground temperatures
Outdoor Equipment
Requires an outdoor heat pump unit
Uses buried ground loops rather than a traditional outdoor condenser
Installation Requirements
Generally simpler installation with indoor and outdoor HVAC equipment
Requires a ground-loop system, which may involve excavation or drilling
Long-Term Performance
Dependable year-round heating and cooling with proper sizing and maintenance
Underground loops can have a particularly long service life
Ideal Property Type
Works well for many existing homes seeking efficient heating and cooling with less installation
Often best for homeowners with suitable property conditions who prioritize long-term efficiency
Benefits of Geothermal Heat Pumps
Geothermal heating and cooling involves a larger installation project than a typical air-source system, but it can provide several long-term advantages for the right home and property.
- Efficient Year-Round Comfort: Geothermal systems take advantage of relatively stable ground temperatures to efficiently transfer heat into or out of your home throughout the year.
- Consistent Cold-Weather Performance: Because a ground-source heat pump does not rely directly on frigid outdoor air for heat exchange, its performance is less affected by Wisconsin temperature swings.
- Heating & Cooling From One System: A geothermal heat pump provides both winter heating and summer air conditioning, eliminating the need for separate furnace and AC equipment in many applications.
- Long-Lasting Ground Loops: The buried loop portion of a geothermal system can remain in service for decades, even as the indoor heat pump equipment eventually requires replacement.
