Signs Your HVAC System Needs Attention

Many heating and cooling issues don’t begin with a full system failure. Often, your system gives you subtle signs that something’s wrong. Catching these early helps prevent bigger, more expensive problems later on.

Watch out for:

  • Inconsistent temperatures between rooms
  • AC or heat running constantly without reaching set temperature
  • Unusual noises like banging, screeching, or clicking
  • Weak airflow from vents
  • Frequent system cycling or failure to start
  • Higher-than-normal energy bills
  • Thermostat not responding properly
