Prepping Your Heating System for Cooler Weather

As the leaves begin to turn and a crispness fills the air, our minds naturally turn to cozy sweaters, warm drinks, and the comfort of a heated home. But before the temperatures take a serious dip, there's a crucial task every homeowner should tackle: preparing the heating system for the cooler weather ahead. A little proactive maintenance not only ensures your system runs efficiently but can also save you from the inconvenience and expense of a sudden breakdown on the coldest night of the year.

Most of us don't think about our heating system until we need it. Out of sight, out of mind, right? But neglecting your furnace or heat pump can lead to a host of problems, from dusty, allergen-filled air to a complete system failure. The good news is that many of the essential prep tasks are simple enough for any homeowner to handle. However, for a comprehensive check-up and to address any underlying issues, it's always a good idea to enlist the help of a company that provides professional heating services. A trained technician can spot potential problems that might otherwise go unnoticed, ensuring your system is safe and ready for the demands of winter.

DIY Heating System Prep: A Homeowner's Checklist

Before you call in the pros, there are several things you can do to get your heating system in shape for the season.

Change the Air Filter: This is perhaps the easiest and most impactful task. A dirty, clogged filter restricts airflow, forcing your system to work harder and less efficiently. It can also lead to poorer indoor air quality. Check your filter monthly and replace it if it's dirty. At a minimum, you should be replacing it every three months.

Clear the Area Around Your Unit: Whether your furnace is in a closet, the basement, or the attic, make sure the area around it is clear of any clutter or flammable materials. This ensures proper airflow and is a critical safety measure. For outdoor heat pump units, remove any leaves, branches, or other debris that has accumulated.

Check Your Vents and Registers: Walk through your home and make sure that all your heating vents and registers are open and unobstructed. Furniture, rugs, and curtains can all block the flow of warm air, making your system work harder to heat your home.

Test Your Thermostat: It's a good idea to test your heating system before you actually need it. Turn your thermostat to "heat" and set the temperature a few degrees higher than the current room temperature. You should hear the system kick on and feel warm air coming from the vents within a few minutes. If not, you may have a thermostat issue or a larger problem that needs professional attention.

When to Call a Professional

While DIY maintenance is important, it's not a substitute for an annual professional tune-up. An HVAC technician will perform a more thorough inspection and cleaning, which can include:

Inspecting and cleaning the internal components: This includes the burners, flame sensor, and heat exchanger.

Checking for gas leaks and carbon monoxide: This is a critical safety check to protect your family.

Testing electrical connections and components: This helps to prevent system failures and ensure safe operation.

Lubricating moving parts: This reduces friction and wear and tear on your system.

Don't Forget the Big Picture

Prepping your heating system is also a great time to think about your home's overall energy efficiency. Sealing air leaks around windows and doors, adding insulation, and even reversing the direction of your ceiling fans can all help to keep your home warm and your energy bills down.
