Common HVAC Problems and Solutions

Why This Matters

HVAC problems range from minor to system failures. Understanding common issues helps you decide DIY vs professional.

Key Signs to Watch For

• Uneven heating/cooling: Duct leaks, dirty filters, or improper sizing.
• System won't turn on: Check thermostat batteries, breaker, power switch.
• Frozen coil: Dirty filters, low refrigerant, poor airflow.
• Water leaks: Clogged condensate drain line.
• Short cycling: Oversized unit or electrical issue.

What You Should Do

1. Always start with the filter — A $5 filter solves many problems.

2. Check the breaker — Tripped breaker is common.

3. Clear condensate line — Pour bleach down to kill algae.

When to Call a Professional

If basic troubleshooting doesn't work, or if you suspect refrigerant or electrical issues, call an HVAC professional.
