Troubleshooting guide
Heat pump remote not working? Here is what is happening and what to do.
A heat pump remote that won't work is usually dead batteries (try fresh ones first), an obstructed IR sensor, a failed remote, or a paired-mode issue. If new batteries don't fix it, most major brands sell replacement remotes for $20-40. Pairing instructions are model-specific.

When a cleaning helps, and when to call a repair pro
A good portion of “something is off” symptoms (musty smell, weak airflow, water dripping from the indoor unit, surface mold) trace back to a dirty blower wheel, clogged drain, or biofilm on the coil. A full disassembly cleaning solves those. If we get on site and find an electrical or mechanical fault (a failing capacitor, a stuck reversing valve, refrigerant issues), we will tell you and recommend a heat pump repair contractor. We do not do repairs ourselves.
