Furnace Maintainance Tips

Here are the furnace maintainance tips to follow:

1. Clean and inspect the furnace

Step 1: Open the panel for the furnace.

Use a screwdriver to take off the screws on the front of your furnace. This will let you see the internal parts of the computer.

Step 2: Clean the interior.

Dust and other things can build up in the furnace. Use a vacuum cleaner that has a hose attachment to clean the blower, belts, and other parts. Be careful not to damage any parts.

Step 3: Wash the Blower.

The blower is important for moving air through your furnace and your home. Use a soft brush to get rid of any dirt or dust. This makes the air flow better and less stressful on the blower motor.

2. Replace the Air Filter

Step 1: Remove the Air Filter

The air filter usually is near the return air duct or blower compartment. If you’re not sure, check your furnace manual.

Step 2: Remove the Old Filter.

Slide the old filter carefully out. Note the direction of the airflow on the filter frame.

Step 3: Put in the new filter.

Put in a new filter and make sure the airflow direction matches the directions on the furnace. A clean filter makes the air better and makes the furnace work faster.

3. Checking the Thermostat

Check the thermostat.

Turn the heat up on your thermostat and wait for the furnace to start. If it won’t start, check the batteries and settings on your thermostat.

Clean the thermostat.

If your thermostat has a removable cover, use a soft brush or cloth to clean the dust. Dust can mess up its sensors and make the results wrong.

4. Check the ventilation

Step 1: Check for blocks.

Go through your house and check all the vents and pipes. Make sure they don’t get blocked by furniture, rugs, or other items. Blocked vents can make your furnace less efficient and make it work harder.

Step 2: Clean The Vents

Use a vacuum cleaner to clean the vents. Clean vents improve air flow and air quality in your home.

5. Gas Leaks

If you smell gas, turn off the gas supply immediately and leave your home. Call a professional to inspect and repair the leak.
