Top Furnace Safety Tips

Is your furnace ready for the long, cold winter ahead?

When the chilly days of winter roll in, you don’t want to be worrying about your heating system. Keeping your home’s furnace in top condition for the coldest months helps guarantee that you and your family stay warm throughout the season. Take the time to complete maintenance activities before the first snowfall. There are several things you can do to prepare your heating system to tackle winter temperatures. Here are Johnson’s top furnace safety tips:


Have your furnace cleaned and checked every year by a professional, expert technician at Johnson’s! An annual furnace check-up is essential in making sure that the system is working well and operating efficiently. A service technician from Johnson’s will conduct all the necessary safety and performance diagnostics and provide you with an overview of the health of your system. Your furnace will also be checked for problems such as carbon monoxide leaks or frayed electrical wires that could lead to safety hazards in your home.


It is important to change your furnace filter regularly. A clean air filter will help your furnace burn more efficiently and will help keep dust from being circulated through your home. A dirty filter can cause a number of efficiency, performance and safety issues, as well as result in furnace failure. Look for filters with a high MERV (Minimum Efficiency Reporting Value) rating that also allow for maximum airflow within the home. Change or clean your air filter every 1-3 months during the winter when the furnace is being used the most.


If your furnace isn’t functioning properly, one of the biggest threats that it can impose to your home is a carbon monoxide leak. Carbon monoxide is a type of gas that is colorless and odorless, so there is no way to detect high levels of it on your own. A carbon monoxide leak can cause us to have flu-like symptoms, disorientation, confusion and even death. It is imperative to check that all of your home’s carbon monoxide detectors are working properly.


Test and make sure that your smoke alarms are in working condition. Test them every month when you check you air filter. Replace batteries every 6 months or so and replace all smoke alarms that are over 10 years old. Working smoke alarms reduce your risk of dying in a home fire by half!


In order to minimize the chance of a fire, it would be smart to keep the area around your furnace clear. Flammable products such as papers, sawdust, old rags and wood scraps should be kept a safe distance away from the furnace. Liquids such as gasoline and kerosene should be stored in tightly sealed containers, since vapors from flammable liquids easily ignite.


You should also check your ventilation system for any problems. You can clean out your vents to remove dust, debris and other things. You should also check the condition of your vents. If they’re dented or damaged, you should have them replaced to ensure that the air can flow through them unimpeded. Also, open all of your air vents. Remove furniture, boxes and clutter that get in the way of air flowing from the vents.


Is your thermostat in proper working order? Check the calibration to make sure that the temperature readings are accurate. Furnace thermostats that fluctuate and waver can lead to inconsistent temperatures throughout the day. As a result, family members may be constantly raising and lowering the thermostat several times a day. This causes the system to work harder, leading to increased energy bills and perhaps further expensive maintenance repairs in the future. To ensure proper calibration of your thermostat, contact Johnson’s and have a technician analyze your heating system to look for possible issues.
