Before you call for emergency HVAC service, use this checklist!

The following checklist is a way to help you troubleshoot common HVAC issues before you call for emergency service. It’s practical and can save you both time and money.

Pre-Call Checklist for HVAC Issues

1. Check the Circuit Breaker:

• Action: Ensure the circuit breaker for your HVAC system hasn’t tripped.
• If Tripped: Reset the breaker. If it trips again, there may be an underlying issue that requires professional repair.

2. Verify Thermostat Settings:

• Action: Confirm that your thermostat is set to “Cool” or “Auto.” Set the temperature to a lower setting and wait for at least 5 minutes.
• If Unchanged: Check for any other thermostat issues or battery problems.

3. Power Off Before Inspection:

• Action: Turn off the power to your A/C unit at the breaker before inspecting the machinery or fan assembly.
• Why: This ensures safety and prevents damage while you investigate.

4. Inspect for Obstructions:

• Action: Listen for unusual sounds like clanking. If you hear them, check if a branch, twig, or small critter has entered the fan assembly.
• Solution: Remove any debris carefully, and ensure the area is clear of obstacles.

5. Check for Power Outages:

• Action: Confirm that there hasn’t been a recent power failure.
• How: Check other electrical devices in your home to see if they are functioning.

Additional Tips

• Filters: Check if your air filter is clogged and needs replacing. A dirty filter can affect system performance.
• Drain Line: Ensure the condensate drain line is not blocked. A clogged drain can cause water damage and system shutdown.
• Registers: Make sure all air vents are open and unobstructed.
