What owners ask.

It depends on the loop. A vertical loop goes down, so a few bores can fit beside a house. A horizontal field needs open ground, often a good part of an acre. A lake loop needs no yard at all, only the right water. We size the field from your house's heat loss and say what it needs before you decide.

Some. A drill rig and trucks leave ruts, and trenches leave a scar until the ground settles. Your quote says where the equipment goes, what we restore and what we leave to you, such as seed and watering.

The ground below the frost line changes little between January and July, which is why the loop works at all. The heat pump is sized to your house's heat loss, and some systems add electric backup for the coldest days. Your quote says whether yours does and why.

No. Most loops are in the ground. A lake or pond loop is one option when the water is deep and large enough, and when the owner of the lakebed and the state allow it.

Water mixed with an antifreeze, usually propylene glycol or an alcohol. Your quote names which one and the mix.

Yes, and it is the most common retrofit on a lake home. We check the ducts or in-floor tubing first. If the ducts are too small for a heat pump, the quote lists the changes as their own lines.

It depends on the loop, the soil and the house, so we price each job on paper after a site visit. The pricing page lists what decides the number and what the quote includes.

A separate drilling firm, Fischer Drilling, bores the field for us. Your quote names who is responsible for what, from the bores to the restored lawn.

Often. Drilling, buried pipe, electrical and mechanical work can each need one, depending on the township and county. We file them and list them on your quote.

Ask us what your state or utility offers. Programs change, so we check what is in force at your address when we write the quote and list only what we can show you in writing.

The buried pipe is heat-fused polyethylene with no moving parts underground. The heat pump indoors is the part that wears, and it can be replaced without touching the loop.

Get everyone out of the house, then call 911 from outside. Do not go back in. A ground-source heat pump burns nothing, but a propane or oil furnace or water heater still does. Call us once the house has been cleared.
