10 HVAC Troubleshooting Tips Every Homeowner Should Know

There's nothing worse than being without heating or cooling in the middle of summer or winter. That's why it's important to be familiar with some common HVAC troubleshooting tips. Here are ten troubleshooting tips every homeowner should know!

1. Checking the Power

If your HVAC system isn't working properly, the first thing you should do is check the power supply. Ensure the breaker hasn't tripped and that the system is plugged in properly. If your breaker keeps tripping, there may be a problem with the wiring or with the system itself.

2. Cleaning the Filters

One of the most common HVAC problems is a dirty filter. Filters should be cleaned or replaced regularly to ensure optimal performance. A dirty filter can result in decreased airflow and increased energy consumption.

3. Checking the Vents for Blockages

Another common problem is blocked vents. Vents can become blocked by furniture, curtains, or other objects. Make sure all of your vents are clear and unobstructed. If left unchecked for too long, a blocked vent can cause serious damage to your HVAC system.

4. Adjusting the Thermostat

If your HVAC system is running but not heating or cooling properly, you may need to adjust the thermostat. First, check to ensure that it's set to the correct mode (heating or cooling). Then, make sure the temperature is set to the desired level.

5. Checking the Outdoor Unit

The outdoor unit is responsible for cooling your home. If it's not working properly, the problem may be with the unit itself or the wiring. Make sure the outdoor unit is clean and clear of any obstructions. You should also check the wiring to make sure it's properly connected.

6. Look at the Batteries

If your thermostat runs on batteries, they may be the problem. Try replacing the batteries to see if that solves the issue. If not, you may need to replace the thermostat itself.

7. Check for Refrigerant Leaks

If your system is leaking refrigerant, it won't function properly. Refrigerant is the substance that helps cool your home. If you suspect a refrigerant leak, you should call a professional to investigate and repair the problem.

8. Dryer Ignition Issues

If your dryer isn't working, it could be due to ignition issues. The first thing you should do is check the igniter. If it's damaged or defective, it will need to be replaced. You should also check the gas supply to ensure there's enough pressure.

9. Look for Frozen Coils

Frozen coils are a common problem in the winter. If your coils are frozen, it's important to thaw them out as soon as possible. You can do this by turning on the fan and raising the temperature. Once the coils are thawed, you should be able to resume normal operation.

10. Schedule Maintenance Visits

If you're having trouble diagnosing or repairing your HVAC system, it's always best to call in a professional. Schedule regular maintenance visits to keep your system in top shape. Regular maintenance visits will help you avoid major problems down the road.


These are the most common HVAC troubleshooting tips. By familiarizing yourself with these tips, you'll be able to keep your system running smoothly all year long.
