After sitting dormant for months, your heater could be faced with some problems. What if you can’t get your furnace to start running? What if you hear loud or unusual noises coming from your system? What if it’s making a strange smell? While you may only use your furnace for a short time each year, you want it to work without issue when you do. We are going to walk you through some tips for how to prepare your furnace for the fall.

How to Prepare Your Furnace for the Fall

Fall doesn’t begin for another month, but now is a great time to start getting ready for it. While we may not get as cold in Marin, Sonoma, and Napa counties as other parts of the country, it can become rather chilly, especially at night, and you will want to make sure that your HVAC unit is ready for the heat to kick on when you need it to. Preparing your furnace for the fall isn’t much different than getting your HVAC ready for the other seasons; however, the changing seasons are always a good reminder for regular maintenance and upkeep.

Let’s review some things you should do to prepare your furnace for the fall and brisker days ahead.

  • Change Your Air Filter: Replacing your air filters regularly can have a large impact on the health and well-being of everyone in your home and is important and imperative to getting your HVAC system ready for the fall and all year round. Air filters do simply what the name implies, they filter your air. Air filters keep dust and pollen out and are also tasked with keeping larger particles and materials out of your HVAC system, in turn, saving your system from mutilation. Dirty, unchanged filters are a leading cause of issues with Marin, Sonoma, and Napa County HVAC systems. How often you should change your home’s air filter really varies by home. We recommend changing your air filters at least once a month, but there is no exact number of days in which you should change your filters, as each home is different and it depends on the strain you put on your filter, what particles are in the air, and also what type of filter you have.
  • Prepare Your Thermostat: Your thermostat is one of the key components to your home’s HVAC system and can make all the difference between your Novato, CA home maintaining its comfort level or not. There can be indications that your thermostat may need replaced, and checking for them before the cold weather sets in can help you avoid your HVAC system from malfunctioning, or not working at all. Regardless if you have a basic thermostat, programmable thermostat, or SMART thermostat, like all things, there could come a point where you need to make an upgrade. Autumn is a great time to replace the batteries in your thermostat, if yours is battery operated. Also, be sure to make sure you have yours set so that the heat will kick on if needed.
  • Annual Furnace Tune-up: If you really want to make sure your heat is ready for the fall and ensure it is in the best condition possible for the colder weather ahead, you should have it inspected by a HVAC professional. Furnace problems are often caused by lack of maintenance. While you may only use your furnace for a short time each year, regular system inspections and maintenance are crucial to ensuring your comfort come fall and winter. Annual inspections and tune ups help to prevent unexpected breakdowns, and also boosts your heater’s energy efficiency. Preventative HVAC maintenance can help you avoid future headaches and expenses.
