Winterizing my AC unit is something you should not ignore. It helps ensure that your furnace is in the best condition when needed. You must always be ready for the extreme weather that winter brings. You don’t want your AC to be in a dilapidated situation where it cannot deliver to its expectations when the seasons change. Here’s how to get the furnace ready for winter.

1. Test Your Furnace Regularly

Some homeowners tend to wait until the furnace breaks down before they think of calling in a technician. This is not the right way to take care of your appliance. Depending on the model of your furnace, you should test it at least once a month to know if any issues need to be addressed before winter sets in. Keeping your AC in good condition will also improve its lifespan.

2. Clean the Filters

You should clean or replace your furnace’s filters at least once every three months. This is especially important if you have pets in the house. Pet hair and dander can clog the filters and reduce the efficiency of your furnace. Winter is the best time to do this if you have never replaced the filters. Furnaces tend to work harder during the colder months, meaning they will need all the help they can get to function properly.

3. Check for Leaks

Before using your furnace for the season, check for gas leaks. Turn on the furnace and walk around the house with a lit incense stick. If the smoke from the incense stick wavers, it could indicate a gas leak. Do not attempt to fix the problem yourself. Call in a professional to help you out. As you should know, gas leaks can be very dangerous. This is something that you should not take lightly.

4. Inspect the Vents and Ductwork

The vents and ductwork are an important part of the furnace and help to distribute heat evenly throughout the house. If they are blocked, it could lead to hot or cold spots in the home. Inspect the vents and ducts before winter starts. When inspecting the ductwork, look for mold, dust, and debris. These can all contribute to poor indoor air quality. If you find anything wrong with the vents or ducts, have them cleaned or repaired as soon as possible.

5. Get Your Furnace Serviced

Winter is the best time to do this if your furnace has not been serviced in a while. A professional technician will be able to clean and tune up your furnace so that it is ready to take on the cold weather. They will also be able to detect any potential problems with the furnace so they can be fixed before they cause any major damage.


Preparing your furnace for winter is not as difficult as it may seem. By following these simple tips, you can be sure that your furnace will be able to withstand the cold weather. If you have any concerns about your furnace, don’t hesitate to call a professional. Contact BLM Refrigeration Heating & Air Conditioning today to schedule furnace service.
