What to Do Before Turning on Your Furnace


Winter is right around the corner, so it’s time to make sure your furnace is up for the task of keeping your home warm during the cold weather. After all, Windsor, ON, isn’t known for its balmy winters. Before you turn on your furnace for the first time, there are a few things you should do to make sure it’s in peak condition. Our knowledgeable technicians at Guaranteed Comfort Heating & Cooling recommend taking these three steps:

1. Change the Air Filter

Every furnace relies on an air filter to screen dust, dirt, and other yucky particles out of the air. Not only does the filter keep the air in your home cleaner and more breathable, but it also protects your furnace as well. Dirty air filters can actually cause your furnace to work harder, which strains the unit and raises your energy bills. To avoid potential issues, you should plan on replacing your air filter once in the fall and again in the spring.

2. Replace Thermostat Batteries

The thermostat is a small device mounted on an inner wall of your home. It’s also what tells the furnace how warm to make your interior space. Typically, thermostats are battery-powered. That means that when the batteries are low on power, your thermostat will not work. In fact, we’ve had many homeowners think their furnaces were broken when, in reality, their thermostats just needed fresh batteries. Replace the batteries in the fall to avoid any issues come wintertime.

3. Schedule a Professional Tune-Up

A professional tune-up will work wonders for your furnace. Our routine maintenance checklist includes inspecting and cleaning the furnace in addition to making minor repairs and adjustments. We’ll also keep an eye out for any issues that could become major problems down the road.
