Furnace Maintenance for a Healthier Furnace and Extended Lifespan

Before winter sets in, it's important to ensure that your furnace is in good working condition to keep your home warm and safe during the cold Michigan months. Here are some key furnace concerns to address before the winter:

1. Change or Clean the Furnace Air Filter

Why: A clogged or dirty air filter restricts airflow, causing your furnace to work harder, which can reduce efficiency and lead to system failure.
What to do: Check the air filter and replace it if it’s dirty. If your furnace uses a washable filter, clean it according to the manufacturer’s instructions.

2. Inspect the Thermostat

Why: If your thermostat isn't functioning properly, it could lead to uneven heating or prevent your furnace from turning on altogether.
What to do: Make sure the thermostat is set to "heat" and is at the desired temperature. If it's a manual thermostat, check the settings; if it's a smart thermostat, ensure the system is programmed correctly and that the batteries (if applicable) are fresh.

3. Check for Gas Leaks

Why: A gas leak is dangerous and can lead to carbon monoxide poisoning or a fire hazard.
What to do: Smell for any unusual odors (like rotten eggs, which could indicate a gas leak). If you suspect a leak, turn off the gas supply immediately and call us (Proficient Heating & Cooling). Never attempt to fix a gas leak yourself.

4. Clean the Furnace and Vents

Why: Dust, dirt, and debris can clog the furnace and ducts, reducing efficiency and potentially causing the system to overheat.
What to do: Dust and vacuum around the furnace. Clean out any vents and registers to ensure proper airflow. Make sure nothing is obstructing the vents inside your home.

5. Inspect the Pilot Light or Ignition System on the Furnace

Why: If the pilot light or ignition system is faulty, your furnace won’t turn on or stay on.
What to do: If your furnace uses a pilot light, check that it’s lit. If it isn’t, follow the manufacturer’s instructions to relight it. If you have a modern furnace with an electronic ignition system, a technician can check it during an inspection.

6. Check the Furnace Blower and Ductwork

Why: A malfunctioning blower or blocked ductwork can result in uneven heating and strain the furnace.
What to do: Check the blower motor for signs of damage or unusual noises. Inspect the ducts for leaks or blockages, which can reduce airflow and cause the furnace to overheat.

7. Test the Furnace

Why: You want to make sure the furnace is fully operational before the temperatures drop.
What to do: Turn the thermostat to "heat" and set the temperature higher than the room’s current temperature. The furnace should kick on within a few minutes. Listen for any strange noises (like banging, whistling, or rattling), and watch for signs of poor performance, such as weak airflow or uneven heating.

8. Check for Carbon Monoxide Detectors

Why: Furnaces, especially gas-powered ones, can produce carbon monoxide (CO), which is a dangerous, odorless gas.
What to do: Test the carbon monoxide detectors in your home and replace the batteries if needed. Ensure they are installed on each level of your home, near sleeping areas, and in close proximity to the furnace.

9. Consider a Professional Furnace Inspection

Why: Regular professional maintenance can help extend the life of your furnace and catch potential issues before they become big problems.
What to do: Schedule a furnace tune-up with Proficient Heating & Cooling. We can perform a thorough inspection, clean internal components, and check safety features to ensure your system is operating efficiently.

10. Check the Humidity Levels

Why: Michigan winters can be extremely dry, and a furnace can exacerbate the dryness, which can lead to discomfort and potential health issues.
What to do: Consider installing a humidifier on your furnace or using portable humidifiers to maintain healthy humidity levels inside your home. We can install a whole house humidifier for a very affordable price!

11. Look for Signs of Aging or Wear

Why: Older furnaces (typically 15-20 years old) may be less efficient and more prone to breakdowns.
What to do: If your furnace is older, it might be worth having Proficient Heating & Cooling inspect its condition. If you notice increased energy bills, strange noises, or frequent repairs, it may be time to consider replacing it with a new, high efficiency furnace.

12. Inspect the Exhaust System

Why: The furnace’s exhaust flue, which vents gases outside, can become blocked by debris or animal nests, posing a carbon monoxide risk.
What to do: Check the area around the exhaust vent for any blockages or signs of damage. Make sure the vent is clear and properly functioning.

By taking these steps, you can ensure that your furnace is prepared to keep your home warm and safe throughout Michigan’s harsh winter months. If you're not comfortable doing some of these tasks yourself, it's always a good idea to consult Proficient Heating & Cooling to perform a complete system check.
