Every home needs the right heating plan.
IS YOUR HOME SUITABLE?

Every home needs the right heating plan.

Most homes can use a heat pump. The right system depends on a few things we check during a free home assessment.
Insulation: how well your home holds heat
Existing heating: furnace, boiler or radiators
Outdoor space for the outdoor unit
Ductwork, or rooms that suit ductless units
Electrical supply and panel capacity

Voices From Our Customers

Thousands of Twin Cities homeowners trust us with their heating and cooling. Here is what a few of them have to say.

Thermnova sized our heat pump properly and we haven't touched the old furnace all winter. The install crew was tidy and explained everything.
Our upstairs used to be ten degrees warmer than the basement. Two mini splits later, every room is comfortable. Worth every penny.
The quote matched the final bill exactly, and they handled the rebate forms for us. That almost never happens.
Called on a Sunday night with no heat and they were here before nine the next morning. Fixed in an hour.
