What to Do Next

Step-by-Step Action Plan

Follow these steps before calling a technician — you may be able to resolve the issue yourself.

1

Check the Thermostat

Start by verifying that your thermostat is set to the correct mode and temperature. Sometimes, a simple adjustment can resolve heating or cooling issues.

2

Inspect Air Filters

Dirty air filters can restrict airflow and reduce efficiency. Check your filters every month and replace them if they appear clogged or dirty.

3

Examine the Outdoor Unit

Check for any debris or obstructions around the outdoor unit. Clear away leaves, dirt, or anything that may block airflow.

4

Look for Ice Buildup

If you notice ice forming on the heat pump, turn it off and allow it to defrost. This could indicate low refrigerant levels or airflow issues.

5

Monitor for Unusual Noises

Pay attention to any strange noises when the unit operates. If you hear grinding or rattling, it may indicate a mechanical issue.

Pro Tip
Always turn off power to the unit at the breaker before inspecting any components. Safety first — even for simple checks.
