The Dandelion home geothermal system includes:
The cost of Dandelion’s geothermal heating and cooling systems are comparable with traditional HVAC systems. However, the major benefits of geothermal is not having to relay on purchasing expensive heating fuels, and dealing with deliveries. More information on pricing can be found here, but please remember that each system is custom designed to each home’s needs. To get a personal estimate, take our 30 second survey.
See the Dandelion Heat Pump’s technical specifications for more detail.
Dandelion homeowners have a hard time picking one favorite benefit of having a Dandelion home geothermal system. Below are some direct quotes from homeowners sharing what they love most about their Dandelion system:
SAVINGS
COMFORT
CONVENIENCE
INDEPENDENCE
SAFETY
AIR QUALITY AND ENVIRONMENT
The system requires a new air filter every six months. Switching out the air filter takes less than two minutes.
The lifespan of the Heat Pump is 20-25 years. The lifespan of the ground loops is 50+ years.
The Dandelion Heat Pump comes in three heating capacities and two sizes:
Our design team will determine the best-fit size for your home using the data they collect.
The first step is to take this brief questionnaire to see if your home qualifies.
The Dandelion Heat Pump two-stage compressor allows the system to achieve even higher levels of efficiency when the home doesn’t require the full force of the system.
The heat pump produces heat at two levels of intensity:
Stage 1 = Partial load
Stage 2 = Full load
The system operates at Stage 2 to bring the home up to the desired temperature. Once the home has been brought to the homeowner’s desired temperature, the system will switch to Stage 1, and continue to run on its partial load setting. This two-stage system allows the home to maintain a steady, even temperature efficiently, in terms of both energy and cost.
A water-to-air heat pump is a heat pump for homes that use forced hot air heating (homes that distribute heat using ductwork and vents). Water-to-air heat pumps, like the Dandelion Heat Pump, can provide both heating and air conditioning.
This type of heat pump does not work for homes that use radiators to distribute heat. Homes that use radiators will typically require a water-to-water heat pump.
Few things are as critical as making sure a home’s heating system works reliably day after day, year after year. The Dandelion Heat Pump’s monitoring system enables top performance, reliability, and savings.

Dandelion prioritizes new areas based on homeowner demand.
There are a few things homeowners can do to help us prioritize their area:
A home will require one or two ground loops depending on its heating and air conditioning needs. The ground loops are installed vertically by creating a hole approximately 6” in diameter, inserting the loop(s) and then filling in the hole. Because the loops are installed in this way, most yards are large enough to accommodate the ground loops. Dandelion’s team will make a decision based on a number of factors after you’ve completed your 30 second survey.
Once you’re ready to be installed your account manager will contact you with guidance.
The installation happens in three phases:
PHASE 1: Drilling
We drill the vertical bore holes that are used to install the ground loops.
PHASE 2: Trenching
We dig a trench from the bore hole location to your home to connect the ground loops to your geothermal heating & cooling system.
PHASE 3: Interior Install
Lastly, we will remove your existing furnace and install your heat pump, thermostat, and preheated water tank, and any other agreed upon work. This part of the installation takes place inside your home.
The duration of an installation varies based on the factors specific to the home.
Below are typical time frames for each stage of a Dandelion installation:
Ground loops are ~6 inches in diameter, installed to a depth of approximately 500 feet. The exact length will depend on the needs of the given home.
You will need to be home for the parts of the installation that take place inside the home. This includes the installation of the heat pump. You do not need to be home for the installation of the ground loops.
We have three types of drill rigs that are used depending on the access and geological consideration for your property. While our drill rigs vary in size from one another, they are both equally capable of executing the designed job.
Comacchio GEO 600: Track mounted, tight access rig
Terrasonic 150 CC: Track mounted, tight access rig
Atlas COPCO TH60: Truck mounted, and larger in size.
Drill rigs are assigned based on access and surface constraints related to your property. A property that is relatively smaller in size is likely to be assigned a tracked rig.
It is important to understand that potential impact to your yard is not just in the location that the boreholes are drilled, but is also related to the amount of water or dust that the geology on your property produces. For example, if your property has a significant aquifer, the act of drilling will draw more water out of the ground, creating more excess water than other properties.

Dust control:
Dump Trailer:
Drilling location is determined by considering a balance between rig access, trench path, and avoiding utilities so we minimize yard disturbance as much as possible, while still following all the legal requirements necessary to safely work on your property.
Drilling crews typically consist of 2-3 people.
When drilling is complete, you will see the ground loops extend 2-3 ft above ground to let the trenching crew know exactly where the loops are located and where to excavate (these will be cut down). You may have metal casing sticking up until the trenching crew arrives as well. There will also be an overflow of grout, usually grey in consistency and located around the actual borehole. The trenching team is responsible for cleaning up your property and returning it to rough grade.
We use a mini excavator (Bobcat E 32 or E35) that comes on a trailer and is towed by a pick up. We also bring a dump trailer towed by a pick up truck to put drill spoils in.
Trenches are 2ft to 4 ft deep depending on geology and utilities. For trenches above the frostline, the pipes will be insulated.
1-3 people are on a trenching crew. The crew will always consist of 1 crew lead responsible for making sure design is followed.
Our trenching crews will leave your yard in rough grade, meaning they will bring the area back to as close to level as it was previously. We will backfill your trench with soil from your property and do not bring in foreign materials. Soil varies in consistency and color at different depths so the finished product may look different than before work began.
Your equipment will be removed from your property and properly disposed of.
A crew consists of 2-3 people. Depending on the size, scope, and complexity of your project, we may decide to send a larger crew. It is most common for the same crew lead to be onsite for the duration of your project. Personnel availability may lend to swapping out crew members from time to time.
Scope of work will dedicate the length of time associated with your project. Most installs take 2 – 4 days per heat pump. Additional time will be required for additional product options.
You will need to be home for the parts of the installation that take place inside the home. This includes the installation of the heat pump. You do not need to be home for the installation of the ground loops.
It is our goal to never leave you without heating. We are typically able to have at least temporary heat up within the same day of removing your old system. In extenuating circumstances we will provide you with temporary heat which may include space heaters.
We don’t provide additional air conditioning support, but work to get your unit functioning as quickly as possible.
