Heat pumps & ductless
Heat pump installation
A heat pump heats and cools with one outdoor unit by moving heat instead of burning fuel. Correct sizing for your winter design temperature, a cold-climate model where winters are harsh, and a plan for backup heat are what make it comfortable.

Today's variable-speed and cold-climate heat pumps keep producing useful heat well below freezing. In the South and on the West Coast a standard heat pump often replaces both furnace and AC; in the North many homes pair it with a gas furnace as a dual-fuel system.
Ask the installer to size the heat pump for heating, not just cooling, and to show its rated capacity at your area's coldest typical temperature.

What affects the cost
Prices are set by the contractor after diagnosis. These are the factors that move the number most:
- Standard vs. cold-climate, variable-speed equipment
- Ductwork condition or ductless heads
- Electrical panel or circuit upgrades
- Backup heat (strips or existing furnace)
- Rebates and tax credits available where you live
Safe to check yourself
- Collect a year of energy bills
- Check your utility and state energy office for incentives
- Note your electrical panel's amperage
Leave to a pro
- Electrical or refrigerant work
- Mounting the outdoor unit where roof snow or drip will bury it
Heat Pump Installation FAQ
Do heat pumps work in cold climates?
Cold-climate models are designed to keep heating at temperatures well below 0°F, with reduced capacity. In very cold areas they are often paired with backup heat for the coldest days.
Will a heat pump lower my bills?
It usually lowers costs compared with electric resistance, oil or propane heat. Compared with cheap natural gas, savings depend on local electricity and gas rates.
Can a heat pump use my existing ducts?
Often yes, if the ducts are sized for the airflow a heat pump needs. Undersized or leaky ducts should be fixed during installation.
What is a cold-climate heat pump?
A cold-climate heat pump is designed to keep producing useful heat at very low outdoor temperatures, often well below 0°F, using variable-speed compressors and enhanced refrigerant circuits.
What is the balance point?
The balance point is the outdoor temperature below which a heat pump alone can't meet the home's heat loss. Below it, backup heat makes up the difference.
What does HSPF2 mean?
HSPF2 is the federal heating-efficiency rating for heat pumps. Higher HSPF2 means more heat per unit of electricity over a typical heating season.
Do I need a bigger electrical panel for a heat pump?
Not always. Many homes can add a heat pump on existing service, but homes with small panels or electric backup heat may need an upgrade. The installer should check before quoting.
Will a heat pump work with my existing furnace?
Yes, as a dual-fuel system. The heat pump handles cooling and most heating, and the furnace takes over in very cold weather.
