Can I fix my HVAC myself?
Homeowners can safely perform basic maintenance like changing air filters or resetting a circuit breaker. However, repairs involving gas lines, complex electrical components, or refrigerant require specialized knowledge and tools. For most issues in Chicago, professional HVAC service is recommended.
What should I do if my furnace is blowing cold air in Chicago?
If your furnace is blowing cold air, first check your thermostat settings and ensure it's set to 'heat' and not 'fan only.' Also, check your circuit breaker. If these simple checks don't resolve the issue, it likely requires a professional diagnosis for problems like a faulty ignitor or gas valve.
