1. No Heat on a Freezing Winter Night

Emergencies often strike when you least expect them, like a sudden loss of heating on a frigid winter night. If your HVAC system fails to produce heat, here's what to do:

  • Check the Thermostat: Ensure it's set to "heat" and at your desired temperature.

  • Inspect the Circuit Breaker: Make sure the HVAC breaker hasn't tripped.

  • Change the Air Filter: A clogged filter can restrict airflow; replace it if necessary.

  • Call a Professional: If these steps don't restore heat, it's time to call an HVAC expert.

2. AC Failure During a Sweltering Summer

When the summer sun is scorching, a malfunctioning AC system can be unbearable. Here's a checklist for AC emergencies:

  • Thermostat Settings: Verify the thermostat is set to "cool" and the desired temperature.

  • Circuit Breaker: Check if the AC breaker has tripped.

  • Clean or Replace Filters: Dirty filters can impede cooling; replace them if needed.

  • Professional Help: If the AC is still not working, it's time to contact an HVAC professional.

3. Strange Noises and Odors

Unusual sounds or odors emanating from your HVAC system can be signs of trouble. Here's what to do:

  • Listen Closely: Identify the type and location of unusual sounds.

  • Shut It Off: If you hear grinding or banging, turn off the system immediately.

  • Check for Odors: If you detect burning or musty odors, it's time to act.

  • Call an Expert: For unusual noises or odors, it's best to consult an HVAC professional to diagnose and resolve the issue.

4. Refrigerant Leaks

Refrigerant leaks not only impair cooling but can also be harmful. Here's what you should do:

  • Safety First: If you suspect a refrigerant leak, turn off your AC system and ventilate the area.

  • Avoid DIY: Refrigerant handling requires expertise; don't attempt to fix it yourself.

  • Contact a Pro: Reach out to an HVAC technician trained in refrigerant handling to locate and repair the leak.

5. Carbon Monoxide (CO) Alarm Activation

If your CO alarm goes off, it indicates a potentially life-threatening situation. Take immediate action:

  • Evacuate: Exit your property immediately and seek fresh air.

  • Call 911: Contact emergency services for assistance.

  • Professional Inspection: Once safe, have an HVAC professional inspect your heating system for CO leaks.
