Troubleshooting Tips to Try at Home Before Calling an HVAC Professional

When your HVAC system isn’t operating as expected, it can disrupt your comfort and peace of mind. However, before you pick up the phone to call a professional, there are a few troubleshooting steps you can try at home. At Salmon’s Heating and Air, situated right in the heart of Central North Carolina, we understand the urgency of HVAC issues. Here are some tips you can use to potentially resolve minor issues yourself and determine whether a professional’s help is necessary.

1. Check the Thermostat

One of the first places to start is your thermostat. It might seem basic, but issues here are surprisingly common.

• Ensure It’s On: Sometimes, the thermostat might be accidentally turned off, knocked off its settings or set to the wrong function.
• Correct Mode: Ensure it’s set to the appropriate mode. If you need cooling, it should be on “cool” and set to a lower temperature. Conversely, if you need heating, it should be set to “heat” with a higher temperature.
• Battery Check: Some thermostats operate on batteries. Dead batteries can cause the thermostat to no longer communicate with your HVAC system.

2. Inspect Circuit Breakers and Power Supply

HVAC systems require a stable power supply to operate efficiently.

• Circuit Breakers: Check your electrical panel for any tripped breakers and reset them if necessary.
• Power Switch: Ensure the power switch near your HVAC unit is turned on. These switches sometimes look like light switches and could be turned off unintentionally.

3. Replace Air Filters

Blocked air filters can significantly hamper your HVAC system’s performance.

• Monthly Check: Ideally, air filters should be checked monthly and replaced every 1-3 months depending on usage and filter type.
• Signs of Blocked Filters: If you notice reduced airflow or dust accumulation around vents, it’s likely time for a new air filter.

4. Clear Debris Around Outdoor Units

Outdoor condenser units need ample airflow to function correctly.

• Debris Removal: Clear away leaves, grass, dirt, and other debris from around the unit. 
• Unit Fins: Check the fins on your condenser unit and gently straighten them with a fin comb if they are bent.

5. Inspect Vents and Ducts

Proper ventilation and ductwork are critical for efficient HVAC operation.

• Open Vents: Ensure all vents in your home are open and unobstructed by furniture, curtains, or other objects.
• Duct Inspection: If accessible, inspect visible ducts for any disconnections or leaks. Leaky ducts can reduce efficiency and comfort.

6. Listen for Unusual Noises

Strange noises can indicate specific issues within your system.

• Rattling or Banging: Loose parts or components might be the cause.
• Whistling or Squealing: This can indicate airflow issues or worn-out blower belts.

7. Monitor Drain Lines and Pans

Condensation is a normal part of HVAC operations but should be properly managed.

• Clear Drain Lines: Ensure that the condensate drain lines are not clogged. You can use a wet/dry vacuum to clear minor blockages.
• Check Drain Pans: Inspect drain pans under your indoor unit for any signs of standing water which can indicate a clog.

8. Reset the System

Sometimes, a system reset is all that’s needed to restore functionality.

• Breaker Reset: Turn off the HVAC system at the breaker, wait 30 seconds, and then turn it back on.
• Thermostat Reset: Reset your thermostat to its default settings and reconfigure it.
