5 Common HVAC Issues and How to Fix Them

Fixing HVAC Issues

When it comes to maintaining your HVAC system, unexpected issues can arise that may leave you feeling overwhelmed. However, understanding common HVAC problems can help you troubleshoot and possibly fix them before calling a professional. In this blog, we’ll explore five common HVAC issues and how to address them effectively.

  1. Thermostat Malfunctions
    If your HVAC system isn't heating or cooling properly, it might be a simple issue with the thermostat. Ensure it’s set to the correct temperature and mode. You may also need to replace batteries or recalibrate it.
  2. Dirty Filters
    A clogged air filter can reduce airflow, causing your system to work harder, potentially leading to damage. Regularly changing your air filters every 1-3 months can prevent this issue.
  3. Refrigerant Leaks
    Low refrigerant levels can cause your AC to lose its cooling power. If you notice warm air coming from your vents, it's time to call a professional to check for leaks and recharge your refrigerant.
  4. Frozen Evaporator Coils
    If your system isn’t cooling as it should, check the evaporator coil for frost. This could be caused by restricted airflow or low refrigerant levels, both requiring professional attention.
  5. Noisy HVAC Unit
    Strange noises like banging, rattling, or whistling often indicate mechanical issues such as loose parts or a failing motor. Don’t ignore these sounds, as they may lead to costly repairs if left unaddressed.
