Question 1

Why Is My Heat Pump Not Cooling on Hot Days?

Accepted Answer

A heat pump not cooling on hot days is usually due to restricted airflow or an incorrect refrigerant charge. The most common trigger is a dirty air filter or a blocked outdoor coil that chokes off heat release. Other frequent causes include thermostat or control issues, a failing capacitor or fan, or a system that’s undersized for the peak load. In our Heathrow work, storm debris and pollen can mat the outdoor coil and quietly cut capacity before you notice warm air. A tech will measure refrigerant pressures, check electrical components, verify airflow, and confirm the thermostat sequence so the fix targets the root cause, not just the symptom. Check these quick signals before a service call: - Replace a dirty filter and clear 2–3 feet around the outdoor unit - Set thermostat to Cool, fan on Auto, and lower the setpoint - Look for ice on copper lines or hear hissing (possible leak; stop and call) - Repeated breaker trips or a dead outdoor fan means service is needed now If the unit is iced, turn it off at the thermostat to thaw before retrying, and book a diagnostic if cooling does not return.

Question 2

How often does a heat pump need professional maintenance?

Accepted Answer

A heat pump needs professional maintenance once a year for most homes. Because it handles both cooling and heating, an annual tune-up helps keep efficiency high and protects your warranty. Routine maintenance reduces surprise breakdowns and supports longer equipment life. In our Central Florida work around Sorrento, long cooling seasons make that yearly visit especially worthwhile. Del-Air’s Maintenance Agreement Plan offers priority scheduling, discounts, and planned tune-ups. - A professional visit typically includes model-specific inspections and verifying the system meets manufacturer specs. - Technicians check electrical components, thermostat operation, refrigerant levels, and airflow. - Coils are cleaned, moving parts lubricated, and settings tuned to restore peak efficiency. Schedule your yearly visit before peak summer to catch small issues early.
