End-of-Summer HVAC & Air Quality Check: Seasonal Home Maintenance You Can’t Skip

As summer winds down, your HVAC system has likely been running overtime to keep your home cool and comfortable. Now is the perfect time to give it some attention—improving efficiency, reducing energy costs, and ensuring your indoor air stays clean before cooler weather arrives.

This simple end-of-season checklist will help you avoid costly repairs later and keep your home running smoothly year-round.

1. Clean or Replace HVAC Filters

Your filters are the first line of defense against dust, pollen, and pet dander. Over summer, they can get clogged, making your system work harder.

Why It Matters:

• Improves airflow and efficiency

• Helps reduce allergens indoors

• Extends your HVAC system’s lifespan

Pro Tip: Mark your calendar or track filter changes in the Home Care + Improvement Planner so you never miss one.

2. Schedule a Professional Inspection

An HVAC technician can spot small issues before they turn into costly repairs.

A seasonal tune-up may include:

• Checking refrigerant levels

• Inspecting electrical components

• Lubricating moving parts

• Testing thermostat accuracy

Best Timing: Late summer or early fall—before demand spikes.

3. Check for Mold or Moisture Buildup

Humidity can leave behind mold in ducts, vents, or near your AC unit.

Signs of trouble:

• Musty odors when the system turns on

• Visible dark spots around vents

• Unexplained allergy symptoms indoors

If you notice any of these, address them immediately to protect both your home and your health.

4. Consider Duct Cleaning

If it’s been 3–5 years since your ducts were cleaned—or you’ve done recent renovations—duct cleaning can improve both air quality and system efficiency.

Benefits:

• Removes dust, debris, and allergens

• Improves airflow

• Helps your system last longer
