You’re probably pretty good at spotting the signs when a person isn’t feeling well. Coughing, sniffling, fever, stomach symptoms, aches, and pains can be pretty obvious. And of course, most people are able to describe how they’re feeling.
What are common signs you need HVAC repair or replacement?
- Strange sounds like banging, rattling, or hissing
- Weak airflow or uneven heating and cooling
- Sudden spikes in energy bills
- Short cycling or frequent system restarts
- System age over 15 years
- Frequent or expensive repairs suggest it may be time for AC and furnace replacement
But your air conditioner can’t tell you what’s wrong, can it? You have to be able to spot the symptoms of AC problems. One of the best ways to do this is with your ears. Listen for these telltale sounds.
