2. Short-Cycling: If your AC turns on and off every 5 minutes, you aren't just wasting power—you are killing your compressor.

3. Strange Odors: A 'dirty sock' smell usually means mold in the coils, while a burning smell is an electrical emergency.

4. The Transition (410A to R32): Did you know the industry is moving away from 410A refrigerant? If your unit is older, a simple leak could cost you thousands in obsolete gas.

5. No Heat or A/C Not Working: if your tried to turn your thermostat on and nothing stop and call
