What should I set my thermostat to during a hard freeze?

During a hard freeze, set the thermostat to a steady temperature, typically 68–70°F. Avoid frequent adjustments, as this can strain the heating system.

Is it normal for my heater to run nonstop during an arctic front?

Yes, it is common for heaters to run continuously during an arctic front, especially in older homes. If the temperature drops significantly below the setpoint, it may indicate a problem.

When is the best time to schedule heater maintenance?

The ideal time for heater maintenance is early fall or between cold fronts. This helps identify issues before peak demand periods.

What are the warning signs that I need emergency HVAC service?

Immediate service is needed if the system won’t turn on, only blows cold air, or emits strong burning smells. Other red flags include unusual noises and significant temperature drops.

How soon can I have a technician to my home?

Appointments are available at various times throughout the day, including 9 AM, 11 AM, 1 PM, and 3 PM, extending up to 8 PM.
