A heat pump moves heat instead of making it, so it cools in summer and heats in winter with the same equipment. Modern cold-climate models hold rated capacity well below freezing, which covers most Boise winter days. Summit Heating & Air installs ducted heat pumps, dual-fuel systems that pair a heat pump with a gas furnace, and ductless mini splits throughout Boise and Boise, Meridian, Nampa, Eagle, and Kuna. Ducted heat pumps replace a central air conditioner and use the existing ductwork. Dual-fuel setups let the heat pump carry mild weather and hand off to the furnace during cold snaps. Ductless mini splits suit older homes without ducts, additions, garages, bonus rooms over the garage, and basements. Each indoor head has its own thermostat. We size every system with a load calculation, check the electrical panel for capacity, and confirm which Idaho Power incentives and federal tax credits may apply before you sign anything.
Signs a heat pump or mini split fits your home
- Your air conditioner is aging and the furnace is still fine
- A room over the garage or an addition never matches the house
- Your older home has no ductwork and runs on baseboard or wall heat
- You want to cut natural gas use without losing winter comfort
- Window units are noisy, blocking light, and running up power bills
- A finished basement or garage shop needs its own heating and cooling
What a heat pump or mini split installation includes
- Load calculation for the whole house or each zone
- Electrical panel evaluation and a dedicated circuit
- Outdoor unit on a pad or wall bracket, raised above the snow line
- Indoor air handler or wall, ceiling, or floor heads for each zone
- Line set, condensate drain, and line hide on exterior walls
- Commissioning, thermostat or remote setup, permit, and incentive paperwork
How a heat pump installation works with us
- We visit, measure the house or the rooms you want to condition, and check the panel and outdoor placement options.
- You get a written proposal with equipment options, a fixed price, and an estimate of the incentives you may qualify for.
- Our crew sets the outdoor unit, mounts the indoor units or air handler, runs the line sets, and pulls a vacuum on the lines.
- We charge the system, test heating and cooling modes, and confirm the defrost cycle and backup heat if fitted.
- We pull the permit, register the warranty, file the rebate forms we can, and show you how to run each zone.
Heat pump and mini split pricing in Boise
A single-zone ductless mini split starts from $4,500 installed. A ducted cold-climate heat pump replacing a central air conditioner starts from $9,500, and multi-zone ductless systems scale with the number of heads. Price depends on capacity, the number of zones, line set length, whether the electrical panel needs a new circuit or an upgrade, and the mounting location for the outdoor unit. Dual-fuel systems that reuse a newer furnace cost less than a full changeout. Idaho Power incentives and federal tax credits can lower the net cost for qualifying equipment, and we show that math in the proposal. Financing is available on approved credit.
Heat pumps in the Boise climate
Boise is a good match for cold-climate heat pumps. Summer highs in the upper 90s and winter lows in the teens both sit inside the range where modern inverter-driven units run efficiently. Idaho Power's rates are low compared with most of the country, which helps the operating cost against natural gas. Older homes in the North End and on the Bench that still use boilers, wall furnaces, or window units are natural candidates for ductless systems, since no ductwork is needed. In Meridian subdivisions, a ducted heat pump can replace the original air conditioner and pair with the existing furnace as a dual-fuel system. The same setup works in Kuna. We mount outdoor units above the snow line and away from roof drip edges.
Questions we get about this
Do heat pumps work in Boise winters?
Yes. Cold-climate models are rated to hold most of their heating capacity at 5 degrees and keep running below zero. On the coldest nights, a backup heat source, either electric strips or a gas furnace in a dual-fuel setup, covers the gap. We size for the design temperature.
What is a dual-fuel system?
A dual-fuel system pairs a heat pump with a gas furnace. The heat pump handles cooling and mild to moderate heating. When outdoor temperatures drop below a set point, the thermostat switches to the furnace. It uses the cheaper fuel at each temperature.
How many mini split heads do I need?
One head per room or zone you want to control separately. A single head can serve an open floor plan. Closed bedrooms each need their own head or a small ducted cassette. We map the house and recommend the fewest heads that give even comfort.
Can a mini split heat a garage or shop?
Yes, and it is one of the most common requests we get. A single-zone unit sized for the space will heat and cool a garage or detached shop. Insulating the garage door and walls first often lets a smaller unit do the job and can lower the running cost.
Are there rebates for heat pumps in Idaho?
Idaho Power offers incentives on qualifying heat pumps and ductless systems, and federal tax credits may apply to equipment meeting efficiency thresholds. Amounts and rules change. We confirm current programs when we quote and complete the utility paperwork we are able to.
Will my electrical panel handle a heat pump?
Most homes built after 1990 have a 200-amp panel with room for the circuit. Older North End and Bench homes may have 100-amp service or full panels. We check on the first visit and include any electrical work in the proposal, with no surprises later.
