Top HVAC Troubleshooting Tips Every Homeowner Should Know

Check the Thermostat:

Sometimes the issue is as simple as a thermostat setting. Ensure your thermostat is set to the desired temperature and that it is in the correct mode (heating or cooling). Replace the batteries if they are low. If this doesn’t resolve the issue, it might be time to call in a professional.

Inspect the Air Filter:

A clogged air filter can restrict airflow, causing your HVAC system to work harder and less efficiently. Check the air filter monthly and replace it every 1-3 months, depending on your usage and if you have pets. If changing the filter doesn't improve airflow, a deeper issue may be present.

Clean the Area Around Your Outdoor Unit:

Debris such as leaves, grass, and dirt can accumulate around your outdoor unit, obstructing airflow. Regularly inspect the area and remove any debris to ensure optimal performance. If your system still isn’t functioning properly, it’s best to contact a professional.

Check for Blocked Vents and Registers:

Ensure that all vents and registers are open and not obstructed by furniture, curtains, or other objects. Blocked vents can reduce airflow and make your system work harder, potentially leading to breakdowns. Persistent issues might indicate a problem with your ductwork, requiring professional evaluation.

Examine the Circuit Breaker:

If your HVAC system isn't turning on, check your circuit breaker. A tripped breaker could be the culprit. Reset it if necessary, but if it trips repeatedly, you may need to call a professional to investigate the underlying issue.

Inspect Condensate Drain Line:

Your HVAC system has a drain line that removes condensation. If this line becomes clogged, it can cause water damage and reduce system efficiency. Locate the drain line and ensure it is clear of debris. You can use a wet/dry vacuum to remove blockages if needed, but persistent clogs should be handled by a professional.

Listen for Unusual Noises

Unusual noises like banging, rattling, or squealing can indicate issues such as loose components, motor problems, or debris in the system. While some noise is normal, sudden or loud sounds warrant a closer inspection or a call to a professional.

Feel for Proper Airflow

Hold your hand up to the vents to check if the air is flowing properly. If the airflow is weak or inconsistent, it could be due to a dirty air filter, ductwork issues, or a failing blower motor. Address the air filter first, and if the issue persists, consider professional help.

Check the Refrigerant Lines

Low refrigerant levels can lead to inefficient cooling and damage to your compressor. If you notice ice buildup on the refrigerant lines or your system isn’t cooling as it should, you may have a refrigerant leak. This requires professional attention, but you can help by ensuring the lines are clean and free of debris.
