Understanding Mechanical Issue Alerts

What Are Mechanical Issue Alerts?

Mechanical issue alerts are created when GlacierGrid detects patterns in your system that indicate abnormal HVAC behavior.

These alerts are based on data from your thermostats, zone sensors, and other system inputs.

• Alerts open automatically once a condition is confirmed
• Alerts close automatically once the issue is no longer detected
• No manual action is required to clear an alert

Because the system is designed to avoid false alarms, alerts are only created after the issue has been consistently observed.

What Should I Do If I Receive an Alert?

These alerts are designed to reduce guesswork by pointing you to the most likely cause and next step.

Start with the issue name shown in your dashboard or alert.

Each alert identifies a specific type of problem and helps guide your next step:

• Some issues can be checked on-site, such as doors, setpoints, or schedules
• Some may require contacting your HVAC service provider
• Some may require contacting GlacierGrid Support

If you are unsure, please contact GlacierGrid Support at support@glaciergrid.com.

Mechanical Issue Alerts

Thermostat Issue

What it means
The thermostat is not calling for heating or cooling even though the space temperature is outside the setpoint range.

What to do
Contact GlacierGrid Support. This is often related to configuration, communication, or control behavior and may not require a technician.

No HVAC Output

What it means
Your HVAC system is running but not producing any meaningful heating or cooling.

What to do
Contact your HVAC service provider. This typically indicates a mechanical failure that requires service.

HVAC Underperforming

What it means
Your system is producing some heating or cooling, but not enough to effectively condition the space.

What to do
If this alert continues or repeats, consider contacting your HVAC service provider. This may indicate a developing issue.

Capacity Issue

What it means
Your HVAC system is working but cannot keep up with the temperature demand, often during extreme outdoor conditions.

What to do
If this occurs frequently, contact your HVAC service provider to evaluate system performance or capacity.

Temperature Not Maintained

What it means
Your HVAC system is running and producing conditioned air, but the space is not reaching the setpoint.

What to do
Check for building-related causes first, such as:

• Doors or windows left open
• Air leaks or insulation issues
• High internal heat load

If the issue continues, contact your HVAC service provider.

Economizer Issue

What it means
The economizer may not be operating correctly and could be affecting heating or cooling performance.

What to do
If this alert repeats, contact your HVAC service provider.

Frequent Mode Switching

What it means
Your system is rapidly switching between heating and cooling.

What to do
Review your thermostat setpoints and schedules. If heating and cooling setpoints are too close together, adjust them.
If the issue continues, contact GlacierGrid Support.

Why Didn’t I See This Sooner?

GlacierGrid is designed to avoid false alerts.

Depending on the issue, the system either:

• Waits for several hours of consistent data
• Evaluates full heating or cooling cycles

This ensures alerts reflect real, sustained issues rather than brief fluctuations.

If you prefer earlier alerts, you can adjust your issue configuration settings.

Frequently Asked Questions

Will the alert close on its own?
Yes. Alerts automatically resolve once the system detects that the issue is no longer present.

What should I tell my HVAC technician?
Share the issue name. It tells them what type of problem to investigate.

What if I think something is wrong but I didn’t get an alert?
The system is intentionally conservative to reduce false alarms. If you suspect an issue, please contact GlacierGrid Support.
