Alberta homeowner guide
A useful geothermal quote explains the complete system and the work needed to make it perform. The headline price alone cannot tell you whether two proposals cover the same ground loop, heating capacity, distribution upgrades or restoration. This checklist helps Alberta homeowners compare scope before choosing an installer.
Discuss your projectStart with the home, not a standard equipment package
Before comparing prices, confirm that each proposal starts from the same building information. Floor area is useful background, but windows, insulation, air leakage, ceiling heights and the local winter design condition all affect heat loss. A quote based only on square footage may hide an equipment or loop sizing assumption that changes the project later.
Ask whether the installer has allowed for your planned renovations. New windows, an addition, attic insulation or a finished basement can alter the loads. Identify what is included in the assessment and when a final calculation will be delivered. Our geothermal sizing guide explains why nominal tonnage alone is not a design.
Provide recent energy bills, equipment model numbers and a list of rooms that are hard to heat. These help establish a useful baseline. Existing bills support the analysis; they do not replace a proper heating and cooling load calculation.
Make the ground loop scope visible
A horizontal and a vertical proposal can both be reasonable, but they represent different construction work. Each quote should describe the proposed loop arrangement, the site assumptions and the reason it suits your property. A diagram is often more useful than a single line saying “ground loop included.”
Ask what happens if drilling encounters unexpected conditions or access differs from the initial visit. Confirm the agreed process for changes, the pricing basis and who approves additional work. Bore depth, trench depth and loop length should come from the design rather than a universal rule for Alberta.
The proposal should address utility locating, equipment access, pipe connections, testing, loop fluid and records of the installed field. It should also distinguish initial backfilling from finished landscaping. Read about horizontal and vertical ground loops before comparing alternatives.
Separate equipment from the complete comfort system
The indoor heat pump is one part of the installation. Ask for the model, heating and cooling configuration, controls and any supplemental heat. The proposal should explain capacity at the expected operating conditions, rather than relying only on the model’s nominal rating.
Existing ductwork, radiant floors or fan coils may need changes. Confirm whether those changes, condensate drainage, electrical work and domestic hot-water options are included. A desuperheater or dedicated water-heating function is an optional design feature; it is not implied by the word geothermal.
If one proposal retains the existing distribution system and another replaces it, compare those choices separately. Our radiant heating guide and summer cooling guide help explain the different requirements.
Use a scope comparison table
| Item | What to confirm in writing |
|---|---|
| Design | Loads, loop assumptions, equipment selection and backup strategy |
| Construction | Access, utility locates, drilling or trenching, disposal and restoration |
| Connections | Electrical, ductwork or hydronics, drainage and controls |
| Permits | Who applies, pays and arranges inspections |
| Handover | Test results, settings, manuals, loop records and owner training |
| Protection | Separate equipment, labour and ground loop warranty terms |
Use the same checklist for each installer. Mark an item “excluded” or “not yet specified” rather than assuming it is included. A lower price may reflect a smaller scope, a different restoration allowance or an incomplete distribution upgrade. The comparison becomes useful when those differences are visible.
Check financial assumptions and the change process
Ask for an itemized price, taxes, payment milestones and a written description of exclusions. Keep financing separate from installation cost: loan payments, interest and program fees belong in the financial comparison. Funding should enter the budget only after eligibility and any required approval are confirmed.
An operating-cost estimate should identify energy prices, seasonal performance assumptions, auxiliary heat and pumping energy. Request a range or sensitivity analysis instead of a guaranteed savings percentage. If a natural gas connection will remain for another appliance, its fixed charges may remain too.
Finally, agree how changes will be documented. A written change order should describe the reason, cost and schedule impact before the extra work proceeds. Alberta’s guidance on hiring a contractor provides a useful starting point for comparing estimates and contracts.
Ask how the installation will be handed over
Commissioning is the point where the installed system is checked against the design. Ask which operating modes will be tested, what measurements will be recorded and how any unfinished items will be resolved. A quotation should make this work visible.
The handover package should identify the equipment, loop layout, maintenance responsibilities and relevant warranty contacts. Ask for a demonstration of thermostat modes and an explanation of when supplemental heat operates. Clear documentation makes future service easier, including when a different technician attends.
Bring your comparison sheet to a consultation with Envirotech’s residential geothermal team. A complete discussion of scope helps you choose a system for your property and budget with fewer assumptions.
Common questions
Should the cheapest quote always win?
Compare complete scope, design, exclusions and warranty terms first. Price becomes meaningful when the proposals cover comparable work.
Does a geothermal quote include landscaping?
Not automatically. Ask whether it covers only backfilling and grading or also topsoil, sod, paving and planting.
Can an installer guarantee my annual savings?
A useful estimate discloses assumptions. Actual bills depend on weather, usage, tariffs, system performance and any retained fuel connection.
