About the system

  • Is this dual fuel, a heat pump with no new furnace, or all electric?
  • What are the model numbers for the outdoor unit, the coil and the furnace or air handler, and what's the AHRI match number?
  • Is the heat pump single-stage, two-stage or variable-speed?
  • What's its heating capacity at 5°F?

About the house

  • How was it sized, from a load calculation or from the old unit's label?
  • Will the existing ducts and return move enough air?
  • Can the current furnace stay, and if not, why?
  • Where will the outdoor unit sit, and on what?

About the work

  • Is the line set new or reused?
  • What's included for the circuit, the disconnect and any panel work?
  • Is the permit included?
  • What happens to the old equipment?

About the money

  • What's the price before rebates?
  • Which rebates apply, and which come off at signing?
  • What's the labor warranty, and who registers the equipment warranty?

Typical prices for each kind of system are in the margin. Current rebates are on unicolorado.com/rebates.

Common questions

Will I need a new electrical panel?

Not usually. A heat pump needs its own 240 V circuit. A panel upgrade comes up when the panel is full or an all-electric design adds heat strips.

Is a mini-split a heat pump?

Almost always. Most mini-splits heat and cool. Check the model number for the rare cooling-only unit.
