“Roy did a great job servicing our furnace and a/c-heat pump.”
A heat pump that is not cooling on hot days usually points to an airflow restriction or a refrigerant-side issue. Airflow reduction is the most common summer cause because the system cannot shed heat fast enough under heavy load. Low refrigerant, weak fan motors, or control problems can also appear only when outdoor temperatures spike. One technician cue: a system that cools at night but not in the afternoon often has a marginal charge or coil that’s loading up with heat. Our team regularly sees these patterns during Indianapolis heat waves and resolves them with cleaning, testing, and proper charging. For urgent no-cool situations, emergency heat pump repair is available.
Try these quick checks before calling:
- Replace the air filter and confirm all supply and return vents are open.
- Gently hose debris from the outdoor coil fins (power off first).
- Set thermostat to Cool and fan to Auto; confirm the outdoor fan spins.
- If you see ice, repeated breaker trips, or loud humming/clicking, stop using and call for service.
If the outdoor coil feels very hot but indoor air stays warm, turn the system off to prevent damage and schedule a diagnostic.
