It could be either. A severely clogged air filter is a common culprit that restricts airflow, forcing your system to work harder and become less effective. However, if your heat pump is blowing cool air when set to heat (or warm air when set to cool), a faulty reversing valve is a likely cause. Our technicians can quickly diagnose the issue—whether it's a simple filter change or a more complex valve repair—to restore your home's comfort efficiently.

The most telling sign is your heat pump getting 'stuck' in one mode. You might feel cool air coming from your vents when the thermostat is set to heat, or warm air when it's set to cool. You may also hear a hissing sound from the outdoor unit. Given our seasonal temperature swings, a malfunctioning valve can leave you uncomfortable. If you notice these symptoms, it's best to call for service promptly to prevent further strain on the system.

In our area, with pollen, humidity, and seasonal changes, we recommend checking your standard 1-inch air filter every month. It often needs replacement every 1-3 months. During high-pollen spring or dusty summer periods, more frequent changes may be necessary. A clean filter is your first defense—it protects your HVAC equipment, improves efficiency, and maintains good indoor air quality. If you're unsure, our team is happy to advise on the best filter type and schedule for your specific home.
