“Michael did an Excellent job.”
Your heat pump can run without cooling due to thermostat settings, restricted airflow, dirty coils, low refrigerant, or an iced outdoor unit. In Sioux Falls and Alvord homes, we see clogged filters and blocked outdoor fins most often. DRG Mechanical services heat pumps, ductless mini-splits, and geothermal systems, and we offer 24/7 emergency help.
Quick checks:
- Set thermostat to Cool and Fan Auto.
- Replace or wash the filter.
- Clear debris around the outdoor unit.
- If you see ice, turn the system off to thaw.
- If it still blows warm air, schedule service.

DRG Mechanical Inc finds that a heat pump not cooling on hot days is usually due to airflow restrictions, thermostat/control settings, low refrigerant from a leak, or a system that’s undersized for the home. The most common real-world trigger we see is reduced airflow causing the indoor coil to get too cold and the system to stall. Extreme heat simply exposes weak maintenance or sizing that was less noticeable in mild weather. Our technicians handle these hot-day no-cool calls routinely while serving homes around Alvord.
Try these quick checks before scheduling service:
- Replace a dirty filter and make sure all supply/return vents are open.
- Clear leaves and grass from the outdoor unit’s coil on all sides.
- Confirm the thermostat is set to Cool with the fan on Auto.
- Look for frost on refrigerant lines or a tripped breaker; if found, stop and call.
If the issue repeats or the unit struggles even at night, a load calculation can confirm whether repair or right-sizing is the smarter fix.
