Why You Should Consider Turning Off Your Oil Furnace During the Summer

Turning off your oil furnace during the summer can help save energy and money. An oil furnace runs on petroleum, which is a nonrenewable energy source and is expensive.

By shutting off your oil furnace, you are reducing your dependence on this nonrenewable energy source and saving money on energy costs.

Insulation: During the summer months, you can reduce your reliance on your furnace by improving insulation in your home. Adding insulation to your walls and attic can help keep your home cooler and reduce your need to use your furnace.

Weatherization: Weatherization techniques like caulking around windows and doors can help keep warm air out during the summer. This can help keep your home cooler and reduce your need to use your furnace.

Keep Heat Out: Block the sun’s rays from entering your home by using blinds, curtains, or shades on windows. This will help keep your home cooler and reduce your need to use your furnace. These are just some of the reasons why you should consider turning off your oil furnace during the summer.

Benefits of Turning Off an Oil Furnace

Oil furnaces are often used to provide heat in homes during the cold months. However, there are several benefits to turning off an oil furnace during the warmer months.

Energy Efficiency: Turning off an oil furnace during the summer months improves home energy efficiency. When an oil furnace is not running, it is not using energy to heat the home.

This can help reduce monthly energy bills and reduce the amount of pollution caused by burning oil.

Reduce Wear and Tear: Turning off an oil furnace during the summer months can help reduce wear and tear on the furnace. This can help prolong the life of the furnace and save money on repairs.

Maintenance: Shutting off an oil furnace during the summer months can help reduce the amount of maintenance required. When a furnace is not running, it does not need to be serviced or checked. This can save time and money.

Safety: Turning off an oil furnace during the summer months can help ensure the safety of the home. When a furnace is not running, it reduces the risk of carbon monoxide poisoning and other safety hazards.

How to Prepare and Safely Switch Off the Oil Furnace?

To ensure safe and effective switching off of the oil furnace, there are a few steps that need to be considered.

1. Ensure the Furnace is Cool: Before switching off the furnace, it is necessary to make sure that the furnace is cool to avoid any risk of burns. Place a thermometer in the furnace area and wait for it to cool down.

2. Shut off the Power Supply: The next step is to switch off the power supply to the furnace. This is done by switching off the circuit breaker in the furnace control panel.

3. Close the Gas Supply: The gas supply needs to be shut off at the gas meter. Ensure that the marker valve is in the correct position.

4. Shut off the Oil Supply: The oil supply needs to be shut off by closing the valve at the furnace. Drain out any remaining oil from the furnace.

5. Clean the Furnace: Once all the supplies to the furnace have been shut off, it is necessary to clean the furnace of all soot and dirt.

6. Disconnect the Flue: Finally, the flue needs to be disconnected from the furnace. This can be done by unscrewing the flue cap.

Tips for Keeping Your Furnace in Good Condition During the Summer

During the summer months, it is important to keep your furnace in good condition to avoid costly repairs. Here are some tips to help you maintain your furnace efficiently:

Clean the air filter regularly: Clean or replace the air filter on your furnace every month or two. A clogged filter can reduce airflow and strain the fan motor, preventing your furnace from operating efficiently.

Inspect the furnace: Have a professional inspect the furnace annually to ensure it is in good working condition. They can detect any potential issues and make repairs as needed.

Check the thermostat: Inspect the thermostat to ensure it is functioning properly and maintaining the desired temperature. Check the wiring and calibrate the thermostat if necessary.

Check for leaks: Look for signs of leaks such as water on the floor near the furnace or a musty smell. Leaks can cause major damage to the system and should be repaired immediately.

Keep vents clear: Make sure vents and registers are free from dust and debris. Clear away furniture and other items that may be blocking the vents and restricting airflow.

Install a programmable thermostat: Installing a programmable thermostat can help you save money on energy costs. Set the thermostat to a lower temperature when you are away from home and higher when you are home.

Maintaining Your Furnace During the Summer

Summer is an ideal time to maintain your furnace. It is essential to keep your furnace in good condition to ensure its longevity and efficiency during the cold winter months.

Here are some tips to maintain your furnace during the summer:

Clean & Change Filters: It is important to clean and/or replace your air filters every few months. Dirty filters will clog the airways, reducing airflow and causing your furnace to work harder than necessary.

Clean the Unit: Make sure to clean the outside and inside of the unit. Remove all debris and cobwebs that may have accumulated over the winter.

Inspect & Adjust the Burners: Check the burners for any signs of corrosion or build-up. If the burners are worn out or damaged, replace them. Also, adjust the burners to ensure they are in the correct position.

Check the Blower Motor: Make sure the blower motor is running properly. If it appears to be running too slowly, lubricate the bearings. If the motor is still running slow, you may need to replace it.

Test the Thermostat: Test the thermostat to make sure it is working correctly. Replace the batteries if necessary.

Check the Ducts & Vents: Inspect the ducts and vents for any signs of damage. Repair any damaged ducts and vents, as this can reduce energy efficiency and increase energy costs.

Troubleshooting Common Oil Furnace Problems During the Summer

Oil furnaces are a great way to keep your home warm during the winter months. Unfortunately, they can also cause problems during the summer months.

Common issues include not getting enough fuel or air, or having clogged filters. To help you troubleshoot these issues, here are some tips:

Check the Fuel Supply

Make sure the fuel supply is connected correctly and is receiving the right amount of fuel. This can be done by examining the fuel filter and fuel lines. If the filter is clogged, replace it.

Clean the Burners

Check the burners for dirt or debris that may be blocking the airflow. Clean them with a damp cloth and a brush.

Examine the Air Filter

If the air filter has become clogged, it can restrict the flow of air to the furnace. Replace the filter if necessary.

Inspect the Flue and Fuel Pressure

Make sure the flue is clear and open to ensure proper ventilation and if the fuel pressure is too low, the furnace may not be able to burn the fuel properly. Increase the pressure as needed.
