Sizing a heat pump for Ashland County means accounting for what the climate actually does to a system in service, not just what the equipment manual says about capacity. 100 severe weather events were recorded in Ashland County, Wisconsin between 2015 and 2024. At that rate, severe weather is a standing condition of operating here, and a contractor quoting an install has to build that load into the equipment selection and the refrigerant line design from the start. A unit sized for a milder assumption will run harder and recover slower every time conditions push against it.
Ductwork laid down for a furnace was sized and routed around a different kind of airflow entirely. A heat pump moves more air at lower temperatures, and ducts that worked fine for the old system can starve the new one or leave rooms uneven. Half the homes in Ashland County, Wisconsin were built in 1972 or earlier (2020-2024 ACS 5-year). That is the stock a contractor is working through when they crawl the house before anything gets ordered. The electrical panel gets the same scrutiny, because the service that fed the original equipment seldom matches what a heat pump draws. Both have to be assessed before the equipment choice means anything.
What Gets Installed With a New Heat Pump
The outdoor unit is the piece a homeowner sees first, mounted on a pad or bracket beside the house. It holds the compressor and the outdoor coil, and it is where the system does its main exchange with outside air. Inside, the air handler sits in a utility space, basement, or closet and moves conditioned air through the home.
A refrigerant line set runs between the two units, carrying refrigerant through insulated copper tubing along the exterior wall and into the home. The thermostat, mounted on an interior wall, is what the homeowner uses to control the whole system and is replaced or reconfigured as part of the installation.
The drawing shows a general layout of these components, and a licensed contractor determines exactly how each one is positioned and configured for your house.

Severe Weather Events in Ashland County, Year by Year
Ashland County's climate puts real load on heating and cooling equipment, and that load is not uniform across years. A heat pump sized and installed for local conditions handles the range better than one spec'd for somewhere else.
