How buying a system from me works
- 1. Pick a systemSee the equipment price and my flat installation price up front.
- 2. Free Geothermal ConsultationI run a Manual J load calculation on your house and check the ducts. The size comes from the math, not the old nameplate.
- 3. Written quoteYour exact matched system in writing, before anything is ordered.
- 4. Install dayA replacement on your existing loop is usually one day. A new system with a loop takes 3 to 4 days.
Warranty
Every GeoStar system here includes GeoStar’s 10-year parts and labor coverage (GS10PLU). GeoStar’s standard warranty is 18 months on parts. GeoStar’s standard warranty covers parts, and the included GS10PLU adds labor for 10 years. My own labor warranty on GeoStar installs is 2 years, like every geothermal install I do.

Hartzell’s Full Coverage Geothermal Plan
A 10-year lease with $0 upfront and 120 monthly payments, the same every month at the 0% escalator. One payment covers the system, the ground loop, the install, controls, maintenance, filters, repairs and service labor, subject to the contract’s terms. At the end of the term you can choose to own it for about 22% of the job cost, for example about $5,500 on a $25,000 system. During the term it’s a lease, so you own it only if you take that end-of-term option.
Payment examples: $25,000 system = $225 a month; $40,000 system = $332 a month, 120 payments, $0 upfront. Your payment depends on the total cost of your job. These are examples, not a quote.
Disclaimer: Labor, filters, and preventative maintenance are all subject to terms and limitations included in the contract. Inflation-Proof Protection is based on expected inflation costs on services covered under the contract for the ten-year term. Interest Paid is estimated on an annual percentage rate expressed as a yearly percentage and does not imply that the Monthly Payment is exclusive of lease costs related to the geothermal system.
Through third-party ownership, Palmetto can monetize available tax credits and apply that value to the customer’s benefit.
Why geothermal: it runs quiet and steady, with no outdoor unit roaring in July. The loop is the part that lasts: some of my customers are on their third generation of equipment on the same loop. And on the plan, one monthly payment covers repairs and maintenance.
Offered where I install geothermal (the lease isn’t available in Minnesota), on residential projects up to $200,000. See the Full Coverage Geothermal Plan.

2 Available to businesses that depreciate the property. Your tax professional confirms eligibility.
Free Geothermal Consultation: evaluation, consultation and sizing at no charge and no obligation. Saturdays and Sundays I do it statewide, as availability allows. On weekdays I start with a phone call, so send me your utility bills first and then I set the visit. A geothermal diagnostic on a system that is not working is a separate $348 service call.
Utility rebates: you apply for and receive any rebate from your electric utility. I help with the application and give you the equipment details and paperwork the utility asks for. Tell me your ZIP and electric utility, and I check the current program before anyone quotes an amount.
Paying for it
Ways to pay: cash or check (about 10% off every price), credit cards, and financing through Hearth, Wisetack, JB Financing, Klarna, Synchrony and Wells Fargo. Cash is king, and I take cards too. Hearth, Wisetack, Klarna and JB Financing check offers with a soft credit pull, so looking won’t touch your score. Hearth works with credit scores as low as 550. Subject to credit approval.
