Heating & cooling · Replacement & retrofit
HVAC replacement & retrofits in Kansas City.
Replacing broken or aging heating & cooling equipment is the moment to check whether the old system was the right one. GeothermalKC replaces furnaces, air conditioners & heat pumps, & retrofits houses to heat pumps, mini splits or geothermal where that suits the building.
Replacement or retrofit?
A replacement keeps the same kind of system with new equipment, sized to the house as it is now, with indoor & outdoor parts designed to work together.
A retrofit changes the kind of system: a furnace & air conditioner becomes a heat pump, a boiler heated house gains mini splits for cooling, or any of these moves to geothermal. Additions, finished basements, new windows & insulation since the old system went in all change what the house needs.
HVAC & plumbing work is contracted & licensed through GeothermalKC, for homes & new buildings across the Kansas City metro & surrounding counties.
What a replacement includes
- Evaluation of the equipment, ductwork & electrical service
- Equipment sized to the house as it is now
- Matched indoor & outdoor components
- Duct supply & return changes where airflow needs them
- Thermostat & controls
- Removal of the old equipment
- Start up & a walkthrough of the new system

Common questions
Should a new system be bigger than the old one?
Not automatically. The size of the old equipment says little about what the house needs now; additions, insulation, windows & ductwork all change it. The new system is sized to the house as it is today.
Can a furnace & air conditioner be replaced with a heat pump?
Often, yes. A heat pump heats & cools with one outdoor unit, & the ductwork & electrical service are checked first. For the coldest weather, backup heat or a dual fuel setup with a furnace may be part of the design.
Why does an air conditioner freeze up?
Common causes are a clogged filter, closed or blocked vents & returns, a failing blower, a dirty coil or low refrigerant. The first step is to switch cooling off & let the coil thaw, then replace a dirty filter. If it freezes again, the cause needs a diagnosis, & on older equipment that is often when replacement is weighed.
Can geothermal replace a furnace & air conditioner?
Yes, where the lot has room for a ground loop & the ductwork suits a geothermal heat pump. The geothermal replacement & retrofit page covers how that is evaluated.
