HVAC & Appliance Troubleshooter

Something not working right? Select your system or appliance below and answer a few yes/no questions. We'll help you identify the problem and determine if it's something you can fix yourself or if you need professional service.

How It Works

Select the type of equipment having problems, then choose the primary symptom -- such as "not cooling," "making noise," "leaking water," or "won't start." The wizard asks a series of targeted yes/no diagnostic questions that narrow down the likely cause step by step. Based on your answers, you get a probable diagnosis with either DIY fix instructions (if safe to do yourself) or a recommendation to call a professional with an explanation of what the technician will need to check.

Safety is always the top priority. For gas appliances, the wizard checks for gas leak symptoms first. For electrical issues involving high voltage or capacitors, it recommends professional service. The goal is to save you time and money by identifying simple fixes you can handle yourself, while making it clear when professional expertise is needed.

Common Troubleshooting Examples

AC Not Cooling

System
Central AC
Symptom
Blowing warm air
Likely Cause
Dirty air filter
Fix Type
DIY

A clogged filter restricts airflow and can cause the evaporator coil to freeze. Replace the filter and let the system thaw for 2-4 hours before restarting.

Furnace Won't Start

System
Gas Furnace
Symptom
No heat, no fan
Likely Cause
Tripped breaker
Fix Type
DIY

Check your electrical panel for a tripped breaker. Reset it once. If it trips again, there's likely an electrical issue that needs professional diagnosis.

Fridge Not Cold Enough

System
Refrigerator
Symptom
Warm inside, motor running
Likely Cause
Dirty condenser coils
Fix Type
DIY

Dusty condenser coils (under or behind the fridge) reduce cooling efficiency. Vacuum them every 6-12 months for best performance.
