Frequently Asked Questions

Installing a new AC and furnace is priced after an in-home evaluation and load calculation, because system size, ductwork, and options set the total. The biggest driver is the equipment capacity and efficiency required to keep your home comfortable in extreme weather. We confirm details during a brief home visit, then provide clear Good/Better/Best options—usually the same day—and most installs are finished in one day. We use this same process on projects across the Sioux Falls area. For transparency, final pricing is confirmed only after measurements, airflow testing, and safety checks.

When we price your system, we look at:

  • System size and efficiency rating selected after the load calculation
  • Ductwork condition, static pressure fixes, and any return/supply adjustments
  • Add-ons like higher-MERV filtration, whole-home humidifiers, or UV/UV-PCO air treatment
  • Installation complexity, such as new line sets, venting, or thermostat upgrades

Ask about our no-pressure, free comfort analysis if you’re comparing options. For the most accurate number, schedule a home visit so we can measure, test airflow, and give same-day choices.
