Number of zones or rooms
The single biggest lever. Each indoor unit (or, for a heat pump, each duct run it serves) adds equipment and labor — a one-room mini split and a whole-home multi-zone system are very different projects.
One system for heating and cooling, at efficiencies a furnace can't touch. Get connected with an independent, licensed heat pump installer near you.
Modern cold-climate heat pumps heat reliably well below freezing — but only when sized and installed correctly. The installers we connect you with perform proper load calculations, select equipment rated for your winters, and commission the system so it delivers its rated efficiency, not just its brochure numbers.
Not for you if: you just need one or two rooms conditioned — a ductless mini split is the simpler, cheaper fit. Also not for you if your existing furnace and AC are both healthy and you're not trying to change how you heat — a heat pump is a bigger decision than a like-for-like swap, and there's no need to force it before you're ready. This page is about whole-home heating and cooling.
Standard heat pumps lose capacity fast below freezing. Cold-climate-certified (ccASHP) units are tested to maintain a meaningful share of their rated output at 5°F — the spec that actually matters in a real winter, not just the SEER2 headline number.
Single-stage units are simplest and cheapest but run at full blast or off. Variable-speed (inverter) units modulate output to match the load, which is what delivers both the efficiency gains and the even temperatures manufacturers advertise.
In some markets, a heat pump paired with an existing gas furnace as backup costs less to run than either system alone — the furnace only fires below a set outdoor temperature. Whether that math works depends on your local electricity and gas rates; your city page shows the real numbers where we've verified them.
We don't publish a national average price — too many of these vary by home and market to make one honest. Here's what does move it, everywhere.

Cold-climate-rated (ccASHP) systems cost more than standard models. A quote that looks surprisingly low in a cold-winter market may be pricing equipment that isn't rated for your design temperature — ask directly.
Older homes sometimes need a panel upgrade before a heat pump or larger mini-split system can be added. It's a real line item — ask every contractor to assess your panel before quoting.
Long refrigerant line runs, difficult outdoor-unit placement, or wall types that complicate mounting all add labor — why two similar-looking homes can get different quotes.
Most jurisdictions require a mechanical or electrical permit for this work, and the contractor should pull it. A contractor who suggests skipping the permit is a red flag, not a discount.
Licensed HVAC labor is priced by the local market, not a national average — which is exactly why we won't publish one. Two or three local quotes tell you more than any online price chart.
A whole-home load calculation, not a rule of thumb — plus a check of your existing ductwork and electrical capacity.
Exact equipment model, efficiency ratings, and whether the setup is straight replacement or dual-fuel — with the reasoning, not just a price.
Outdoor unit placement, refrigerant line work, and — for ducted systems — any duct modifications, usually completed in one to two days.
Charge verification, airflow testing, and thermostat setup, then inspection scheduling where a permit was pulled — before the installer calls it done.
Heating and cooling from a single unit — no separate furnace and AC.
Heat pumps move heat instead of making it, delivering 2–4x the efficiency of resistance heat.
State and utility incentives can significantly cut project cost where they are active.
Inverter compressors run low and steady instead of blasting on and off.
Every market page we publish cites its own climate and incentive data — a couple of examples:
Yes — modern cold-climate models heat effectively well below 0°F. The key is choosing equipment rated for your region, which your installer will handle.
Both are legitimate. Sizing a heat pump to cover 100% of your coldest-day heat loss costs more up front but ends fuel switching entirely. A smaller unit paired with your existing furnace as backup (dual-fuel) costs less and still runs on the heat pump most of the season. A real load calculation is what turns either option into a number instead of a guess.
Often yes; in the coldest climates some homes keep a backup heat source. Your pro will size the system and tell you honestly what your home needs.
The federal 25C credit expired, but state and utility rebates are still active in many markets. Your city page shows exactly what we've verified as currently active near you.
SEER2 and HSPF2 are seasonal averages; COP (coefficient of performance) at a specific outdoor temperature — often 5°F — tells you how the equipment actually performs on the coldest nights, which matters more in cold climates than the seasonal average.
