Inspect Power Supply

Airflow and Filters

Inspect the Air Filter

Having a clean air filter is really important for good airflow in your home. When filters get dirty, they block the air, making your system work harder. To check if your filter is dirty, just take it out and look at it. If it's dusty or gray, it needs to be changed. Changing the filter is easy.

Check Air Vents and Registers

This will balance the temperature. To improve airflow around the vents, make sure no furniture or curtains block them. You can also clean the vents periodically to remove dust and debris. Good airflow helps your heating and cooling system work well. It keeps your home comfortable.

Ignition and Pilot Light

Inspect the Pilot Light (Gas Furnaces)

The pilot light is a small flame that helps start the furnace. It stays on all the time to be ready. If it goes out, the furnace won't work. Here's how to check it. First, find the pilot light. It's usually near the furnace's burner. Look for a small, blue flame. If it's not there, you'll need to relight it. Get a long match or lighter. Turn the gas valve to "off" for 5 minutes. Then, turn it to "pilot." Hold the flame at the pilot opening and press the reset button. Keep holding the button for 1 minute after lighting. If it still goes out, there may be a problem. Call a professional to look at it.

Check Ignition System (Newer Furnaces)  

Newer furnaces use electronic ignition systems to start. These systems are reliable and efficient. If your furnace isn't starting, here are some steps to try: First, check the power. Make sure the furnace is plugged in and the switch is on. Next, look for any blown fuses or tripped breakers. Sometimes a simple power issue can cause ignition problems. Then, inspect the thermostat. Ensure it's set to heat and the temperature is above the current room temperature. If everything seems okay, check the furnace's control board for error codes. These codes can give clues about what's wrong. Lastly, if you're comfortable, check the pilot light. If it's out, follow the manufacturer's instructions to relight it. If these steps don't work, it might be time to call a professional technician for help.

Motor and Components

Inspect the Blower Motor

If everything seems normal, the motor is likely okay. If it's making unusual noises or not blowing air, it might need fixing. Checking the blower motor is important. It ensures your car's heating and cooling work well. If something seems off, it's a good idea to have a mechanic take a look to keep your car comfortable.

Inspect Air Ducts

Ensuring clear air ducts is vital for good airflow in your home. To check for blockages or damage, follow these steps. First, visually inspect ductwork for any visible obstructions or holes. Look for debris like dust, pet hair, or even small objects that could be blocking airflow. Next, feel for any drafts around the ductwork, as this might indicate leaks. If you find any issues, consider cleaning the ducts or calling a professional for repairs. Remember, good airflow keeps indoor air comfy and healthy for you and your family.

Drainage and Condensation

Check the Condensate Drain

The condensate drain in your air conditioner is important. It helps remove water that builds up during cooling. To check if it's working, follow these steps. First, locate the drain line, usually near the indoor unit. Next, pour a mixture of water and vinegar into the drain to clear any clogs. If it's still blocked, try using a wet/dry vacuum to suction out the debris. Once the drain is clear, water should flow freely. Check the condensate drain often. This can prevent water damage and keep your AC running well.

Resetting and Safety

If it doesn't ignite, avoid repeated attempts, as this could cause damage. It's essential to only reset once and then seek professional help if the problem persists. Safety is paramount, so always follow these steps cautiously to prevent accidents.

Gas Supply Check

When dealing with gas, safety is key. If you smell gas, don't use anything electrical, like switches or phones. Instead, open windows and doors, and leave the area.
