4 Tips to Keep Your Furnace Running Efficiently This Winter

(guest post courtesy of Stella Ohler)


Winter is fast approaching and temperatures are dropping. It’s important to make sure your new AC unit and furnace is running efficiently to keep your home warm and comfortable. Fortunately, there are a few simple steps you can take to ensure your furnace runs at its peak performance throughout the cold winter months.


In this blog post, we’ll cover 4 tips to help keep your furnace running efficiently this winter. From changing the filter regularly to scheduling regular maintenance appointments, these tips will help you keep your home cozy and your utility bills low.


Tip #1: Check your furnace filter monthly and replace it as needed

Maintaining a clean and efficient furnace filter is one of the most important steps to take when it comes to keeping your furnace running efficiently this winter.


The filter is responsible for trapping dirt, dust, and other airborne particles that can clog up your system and reduce airflow. It only makes sense to check monthly and replace it if necessary. A clogged filter will not only make your furnace less efficient but can also cause the system to overwork and eventually break down.


To determine when to change your filter, look for signs such as decreased airflow or reduced air quality. When it's time to replace the filter, make sure to choose the correct size and type for your furnace model.


Choosing the wrong size can lead to a decrease in efficiency as well as damage to your furnace. Additionally, there are many different types of filters available and each has different characteristics. Make sure to pick the right one for your needs and consult with an HVAC technician if you’re unsure.


Lastly, make sure you install the filter correctly to ensure maximum efficiency. If the filter is not properly installed, it won't be able to trap air pollutants efficiently and will decrease your furnace’s performance.


Tip #2: Clean your furnace regularly

Cleaning your furnace can have several benefits. First, it helps to keep dust and dirt from accumulating in the vents, which can block air flow and reduce efficiency. It also helps to eliminate any flammable material that could be a fire hazard. Also, it helps to keep your furnace running more smoothly, reducing the chances of unexpected breakdowns.


To properly clean your furnace, you'll need a few tools and supplies. These include a vacuum cleaner with a long hose attachment, a screwdriver, some rags or paper towels, and a non-toxic cleaner.


Start by using the vacuum cleaner to remove all of the dust and debris from the vents and other areas of the furnace. Then use the screwdriver to open up the access panel so that you can reach inside and thoroughly wipe down all the surfaces. After that, spray down all of the components with the non-toxic cleaner and let it sit for 10 minutes before wiping it off with a rag or paper towel.


Cleaning your furnace regularly is an important part of maintaining its efficiency throughout the winter months. With just a little bit of effort, you can keep your furnace running as efficiently as possible, helping to keep your energy bills low and your home comfortable.


Tip #3: Inspect your ductwork for leaks and seal them as needed

It is important to inspect your ductwork for any leaks or damage. Leaks can cause your furnace to work harder than necessary to maintain the desired temperature in your home, leading to higher energy costs and decreased performance.


Luckily, sealing leaks in your ductwork is relatively simple. Start by inspecting the areas around the joints and seams of the ducts. You should be on the lookout for any cracks, gaps, or disconnected sections. If any of these are present, you will need to seal them using duct mastic. This material is available at most hardware stores and easy to apply.

Foil tape works better to seal air ducts than what is commonly know as "duct tape."

Before sealing any areas, however, you will want to make sure that the surfaces are clean and dry. Cleaning with a damp cloth will help ensure that the mastic seals properly. Once you have applied the mastic, let it dry completely before turning on your furnace.


By preventing cold air from entering the system and warm air from escaping, you can reduce your energy bills and make sure your furnace is performing at its best.


Tip #4: Insulate your ductwork to improve efficiency

When the weather turns cold, keeping your home comfortable can be a challenge. One of the best ways to keep your furnace running efficiently is by insulating your ductwork.


Insulating the ducts that carry air to and from the furnace can help you save energy and money by preventing heated air from escaping through the walls or roof. Here are some tips to get you started on insulating your ductwork:


Measure and purchase the right insulation for your needs – You'll want to measure the size of your ducts and then purchase insulation that is appropriate for their size and shape. Make sure to use insulation rated for high temperatures, since this will ensure that your ductwork remains insulated even during the cold winter months.

Seal all seams – To ensure that your insulation is effective, you'll want to seal any gaps or seams with tape or caulk. This will help to create an airtight seal so that heated air won't escape through the walls or roof.

Test for leaks – Once you have completed the insulation, you'll want to test for any potential leaks. An easy way to do this is by using a smoke pen or incense stick. If you notice any smoke or smell coming from your ducts, you'll need to fix the leak before using your furnace.

Regularly inspect the insulation – Over time, the insulation may start to degrade due to wear and tear or environmental conditions. It's important to regularly inspect your insulation and make sure it is in good condition. If it needs to be replaced, you should do so as soon as possible so that your furnace is running as efficiently as possible.


Stay Warm This Winter with an Efficient Furnace!

As winter weather sets in, it’s important to keep your furnace running efficiently. A well-maintained furnace can not only save money on energy bills, but also prevent costly repairs down the line. Follow these easy tips to keep your furnace running smoothly this winter and ensure it is functioning at its best.
