We need our ACs 24/7 in hot weather so, it is important to keep a check on them to avoid any issues in their functioning and cooling efficiency.

If you pay attention, here are some common air-conditioning problems you can catch early:

1. AC Remote issues: When your AC does not start, the first thing you should check is your remote. Replace the old batteries and it should start working.
2. Less cooling: This surely is one of the most annoying AC glitches. There could be multiple reasons for the same. Check the AC setting, clean filters, or clean the outdoor unit. If nothing works, contact a heating and air conditioning company in Wisconsin Dellsfor expert assistance.
3. High energy bills: Poor insulation can shoot your energy bills up. Always ensure proper insulation and check that AC is free of any debris.
4. Unusual sounds: If you notice that your AC is making unusual clamour it usually indicates an underlying issue with your unit. Switch it off and call for an expert assistance right away.  

Foul smell: If your unit is emitting a foul smell, it is possibly due to dirty coils and clogged up air filters. But in case that it is the refrigerant which has leaked, call a professional immediately.
