Is It a True Emergency?

When your HVAC system acts up, it can be stressful, but not every issue requires immediate attention. Here are some signs to help you determine if it's a true emergency:

  • Emergencies: No cooling or heating in extreme weather, strange noises, burning smells, or gas leaks.
  • Not Emergencies: Uneven heating or cooling, minor temperature fluctuations, or routine maintenance.

Knowing when to call for an emergency repair can save you time and money. If in doubt, don't hesitate to contact us for guidance.

Maintaining Your HVAC System

Prevention is the best cure when it comes to HVAC emergencies. Regular maintenance can help you avoid sudden breakdowns and costly repairs. Here's what you can do:

  • Change Filters: Replace air filters regularly, usually every 1-3 months, to maintain efficient airflow.
  • Clean Vents and Ducts: Keep vents and ducts clean to ensure proper distribution of heated or cooled air.
  • Schedule Annual Inspections: A professional HVAC inspection can catch potential issues before they become emergencies.
  • Program Thermostat: Use a programmable thermostat to regulate temperature efficiently, saving energy and reducing wear on your system.
