5 HVAC Maintenance Tips to Prep for Fall and Winter

Getting your heater ready for fall and winter is a smart move as a homeowner. Taking certain steps can prevent unexpected breakdowns and costly repairs, like a cracked heat exchanger or a failed blower motor. These furnace maintenance tips will also help the HVAC last longer by decreasing wear and tear.

1. Replace or Clean HVAC Filters

The first thing you need to check is the air filter. Double-check its dimensions and rating to make sure you’re using the right size and type.

The correct filter helps the heater operate with optimal airflow and energy performance. It also reduces allergy symptoms by trapping pollen and dust that would otherwise float around the house.

You’ll need to keep the filter changed every one to three months during the fall. This part of the year tends to bring heavy pollen and leaf debris, making timely filter replacements all the more important.

2. Schedule a Professional Heating System Tune-Up

We’ll conduct several tasks during the tune-up to help the unit perform better all winter. Letting a professional handle the maintenance ensures we fix hidden issues that might cause breakdowns later in the season.

• Verify the system runs safely and efficiently
• Inspect the heat exchanger for cracks or damage
• Adjust and test the thermostat for accuracy
• Clean and lubricate moving parts to reduce wear
• Check electrical connections and tighten where needed

We recommend heater tune-ups at least once a year. If you live in a home with older equipment or high energy demands, you may need an additional maintenance visit. Or you could update the heater with a newer model so that you don’t have to schedule service as often.

3. Inspect and Seal Ductwork

If you’re using a forced-air setup, all of your ductwork must be in good condition. Any gaps or cracks in the duct joints or seams will lead to air loss, making the heater work harder.

We can seal leaks or fix misaligned ducts to prevent wasted energy. This process normally takes about two to four hours, depending on the amount of ductwork. The home will not only be more comfortable, but you’ll also save money on heating costs. Plus, since the heater won’t use as much energy, it’ll endure less wear.

4. Check Thermostat and Upgrade if Needed

The next part of preparing your HVAC for fall and winter involves calibrating the thermostat. To do this, simply set the temperature and go to each room with a thermometer. If you notice any uneven heating, there could be a wiring or sensor problem with the thermostat. Or you might have a more serious issue stemming from the HVAC system itself. If you can’t figure out the cause, you’ll need to give us a call.

Adding a smart thermostat is another way to help the heater perform more efficiently. Many models come with algorithms and sensors that learn your daily patterns over time. They use what they learn to adjust temperature settings for better heating with less energy use. Many experts agree that you can save up to 10% on HVAC costs by installing one of these smart devices. If you’re already spending thousands on heating each year, those savings can add up fast.

5. Clear Outdoor Units and Vents

If you’re using a heat pump for heat, it has an outdoor part that houses the condenser coil. This part must have adequate airflow to perform reliably.

Every couple of weeks, check the outdoor unit for leaves and other debris. Clear it away and keep all plants and other obstructions at least 2 to 3 feet from the unit.

Why Preventive Maintenance Pays Off

Preventative maintenance goes beyond keeping your heater running. It delivers lasting benefits, such as:

• Reduced risk of sudden breakdowns
• Boosts energy efficiency
• Lowers monthly utility costs
• Enhanced indoor comfort
• Fixes safety issues

FAQs

When should I schedule fall HVAC maintenance?

We suggest booking maintenance during early fall; this ensures the heater is ready to perform with peak efficiency all winter. It also helps avoid last-minute repairs that often pop up during the first cold snap.

How often should HVAC filters be replaced in winter?

Check the filter’s label to see how often it needs replacing. Most need cleaning or replacement every one to three months.

Is a professional HVAC tune-up really necessary every year?

Yes. Annual tune-ups reduce heating costs by helping the heater use less energy to keep you warm. They also result in less wear, which means a longer-lasting unit and fewer emergency repairs.
