Your Pre-Winter Furnace Checklist

getting furnance ready for winter months

The days have gotten shorter and the nights are cooler which means it’s time to make sure your furnace or HVAC system is prepared for the cold weather and switch your HVAC system over to heat. 

Furnaces, also known as gas forced-air systems, and while they don’t typically require a lot of work by homeowners, a little preventative maintenance goes a long way. While the most important thing you can do is schedule professional furnace maintenance every fall, there are some other things you can do yourself to extend the lifespan of your equipment and save yourself money in the long run. 

Our furnace maintenance checklist will help you ensure your furnace or HVAC system is in top shape before winter hits. 

Turn On Your Thermostat

It’s important to switch your thermostat over from cooling to heating before the cold weather arrives. To do this you need to set the temperature a couple of degrees higher than the current room temperature and listen to hear whether the heat kicks on within a minute. If it doesn’t and the connections are secure and the power source to the HVAC system is turned on. If it’s still not working, you should call in a professional. The issue could be with your furnace fan, blower or heat pump which is best addressed by a trained technician. 

Set Your Thermostat Back A Few Degrees 

Just by setting your thermostat back 7°-10°F for 8 hours every day will not only save you money but it will allow you to customize your temperature settings at different times throughout the day, so you can use less energy while you’re sleeping or not at home. To do this effectively install a programmable or WiFi thermostat to keep your home comfortable at all times. 

Reverse Your Ceiling Fans 

Ceiling fans are great for circulating air throughout all of the seasons. However, in cooler months, by running your fans in a clockwise rotation you will draw cool air up and force warm air down.

Winterize Your AC Unit

Winterizing your A/C unit will help protect it from the winter elements, which can help you save on costly repair bills when the warm weather returns.  Unless your HVAC is a heat pump it’s important that you cover the AC condenser to protect it from falling icicles. You can also use a board to cover the fan just don’t wrap it in a moisture-trapping plastic tarp. 

Change Your Furnace Filter

Replacing your furnace air filter is an easy, cost-effective solution that will help maintain your system over the long run. In fact, just by regularly changing your filter you will not only save on your heating bills but also maximize the lifespan of your furnace.

At the very least you should change your filter with the changing of the seasons, but ideally, you should be checking and changing your filter monthly if necessary. 

Clean the Heat Exchanger

Every year your heat exchanger should be brushed and vacuumed out by a trained professional. During this cleaning, the technician will look for any cracks, which could lead to a carbon monoxide leak into your home.

Make Sure the Air Vents Are Open and Unobstructed

Blocked air vents will cause your furnace to work harder, increasing the system’s temperature and risk of a fire. Before winter arrives remove furniture, plants, toys, equipment or anything else that can obstruct airflow.

Inspect and Clean Heating Ducts

Damaged and dirty air ducts increase your heating bills, negatively affect air quality and put stress on your furnace or HVAC system. Inspect the duct to make sure there are no punctures, dents, disconnected parts, dust, mold or mildew. While you can examine the ducts yourself, maintenance and repair should be done by a professional.

Inspect the Chimney and Carbon Monoxide Detectors

Chimneys can house carbon buildup which is why you should have a professional should inspect them every so often. It’s also important that you regularly test or replace carbon monoxide detectors in your home in the event of a leak or carbon buildup.

Test the Igniter Switch

If you have an older system, you might have to relight the pilot. Newer systems, however, have electronic ignitors. If you find that the ignitor isn’t working, you need to push the reset button. If that still doesn’t do it, try checking your breaker. If both of these steps don’t work, contact us and we’ll send over a technician to look into the issue. 

Clean Your Home

When winter arrives, you’ll be spending more time than ever indoors with the windows sealed shut. So, now is the ideal time to rid your home of dirt, dust, and allergens to improve the indoor air quality and create a more comfortable environment for you and your family.
