Answers to Common Questions
View All FAQsWhy Is My Heat Pump Running But Not Cooling Properly?
A heat pump that runs but won’t cool usually has an airflow restriction, an incorrect control setting, or a refrigerant or valve issue. The most common cause is poor airflow that makes the system move less heat, so rooms feel warm even though the unit is on. Other culprits include a clogged outdoor coil, iced indoor coil, or a stuck reversing valve that leaves the system in the wrong mode. Our technicians often see this in the St. Louis area after pollen or storm debris coats the outdoor unit. A quick technician insight: if the outdoor fan blows but the exhaust air feels weak and warm, the coil is likely packed with dirt you can’t see from the top. When it’s urgent, we offer 24/7 help for cooling failures.
What to check before calling:
- Confirm thermostat is on Cool, not Heat or Emergency Heat.
- Replace a dirty filter, open closed vents, and clear 2–3 feet around the outdoor unit.
- Look for ice on lines or coil; if iced, turn the system off to thaw and schedule service.
- Hissing, short cycling, or lukewarm supply air can indicate low refrigerant or a stuck reversing valve that needs a licensed tech.
If the outdoor unit runs but the indoor blower is off, shut the system off to prevent damage until it’s inspected.

Heat pump installation for a 2,000 sq ft house varies based on equipment, efficiency, and installation scope; final pricing is confirmed after an on‑site assessment. The biggest drivers are system size and efficiency rating, which affect equipment cost and power needs. Our team installs systems throughout the St. Louis metro area, and we factor local permit requirements, when required, into the estimate.
What typically changes the price:
- Equipment size and efficiency (higher SEER/HSPF units cost more but can lower bills)
- Electrical or ductwork changes, line‑set routing, and pad or stand needs
- Required permits and inspections handled for you
- Add‑ons like HVAC surge protection, indoor air quality products, or insulation upgrades
- Placement difficulty and labor time, especially for tight or multi‑story runs
