The Top 5 HVAC Mistakes Homeowners Make in the Fall

When fall arrives in the Capital Region, homeowners shift from cooling to heating without thinking much about their HVAC system. But skipping the right steps in October can lead to higher energy bills, broken furnaces, costly repairs, or even system failure just when you need heat the most.

At Field Industries LLC, we specialize in HVAC repair, furnace service, and boiler maintenance in Clifton Park and surrounding areas. Here are the top 5 mistakes we see every fall and how you can avoid them.

1. Ignoring Your Air Conditioner After Summer

Just because you’re done using your AC doesn’t mean you should forget about it. Failing to inspect and maintain your system after months of heavy use can lead to:

  • Refrigerant leaks going unnoticed until spring

  • Dirty coils and filters restricting airflow

  • Damage from debris around the outdoor unit

Pro Tip: Schedule a post-season AC inspection to prevent problems when you need cooling again next year.

2. Skipping a Furnace or Boiler Tune-Up

The number one fall mistake? Waiting until the first freezing night to turn on your furnace or boiler. That’s often when hidden issues show up, like ignition problems, dirty burners, or safety concerns.

Why it matters:

  • Prevents no-heat emergencies

  • Improves system efficiency (lower heating bills)

  • Extends equipment lifespan

3. Forgetting to Change Air Filters

A dirty filter is one of the most common causes of both heating and cooling problems. In fall, clogged filters can:

  • Restrict airflow, forcing your system to work harder

  • Cause poor indoor air quality

  • Lead to frozen coils or overheating

Pro Tip: Replace filters every 1 - 3 months for better airflow and efficiency.

4. Not Checking the Thermostat

If your thermostat isn’t calibrated correctly, your home may feel too cold or too warm, and your HVAC system may cycle on and off unnecessarily. This wastes energy and creates uneven comfort.

Consider upgrading to a smart thermostat for better temperature control, lower energy bills, and remote access.

5. Waiting Until Something Breaks

The costliest mistake homeowners make in the fall is waiting until their furnace, boiler, or AC actually breaks down. Emergency HVAC repairs are more expensive and stressful than routine service.

Preventive maintenance is always more affordable than a last-minute replacement.
