Indoor Heat Pump Unit Installation Questions

No. The work covers unit placement, ductwork tie-in, refrigerant line routing and pressure testing, PVC condensate drain installation, thermostat wiring, and a startup test that measures supply air temperature and airflow balance. Each step has to be done in sequence and to spec.

Yes. Denver requires a mechanical permit for indoor HVAC equipment installation. The permit is pulled before work begins, not after. Colorado mechanical code also governs refrigerant handling, which requires certified technicians for sealed system work.

A unit that short-cycles or runs with low refrigerant charge puts extra load on the blower motor and compressor. Continued operation in that state can damage components that are otherwise still serviceable, turning a straightforward indoor unit replacement into a larger repair.

No. A geothermal indoor unit is designed to exchange heat with ground-loop fluid, not outdoor air. The refrigerant circuit, operating pressures, and control logic are specific to that system design. Installing a standard air-source unit in its place will not work with the existing ground loop.

Weak airflow, uneven room temperatures, loud operation, or frequent short-cycling all point to the indoor unit. If the ground-side components are still serviceable, the site evaluation will identify whether the indoor unit is the source and whether replacement is the right next step.
