1. Replace or Clean Your Air Filters

One of the simplest and most effective HVAC maintenance tasks is also one of the most overlooked: changing your air filters.

During the summer, your AC has been pulling in dust, pollen, pet dander, and other debris. By fall, your filters are likely clogged, which reduces airflow and makes your system work harder. This not only increases energy bills but also decreases indoor air quality.

• Tip: Replace your air filter every 1–3 months depending on the type of filter, whether you have pets, or if someone in your home suffers from allergies.
• Local insight: In Lake Norman and Cornelius, fall allergy season can still trigger sneezing and itchy eyes. Clean filters help trap allergens before they circulate indoors.

2. Schedule a Professional HVAC Tune-Up

Think of your HVAC system like your car: you wouldn’t drive cross-country without an oil change and inspection. The same goes for your heating system. A fall HVAC tune-up ensures everything is working properly before you switch from cooling to heating.

A professional tune-up from R&B Climate includes:

• Inspecting your furnace or heat pump for wear and tear
• Checking safety components like carbon monoxide detectors
• Cleaning internal parts to improve airflow and efficiency
• Testing thermostat accuracy
• Lubricating moving parts to prevent breakdowns

Not only does a tune-up help prevent unexpected breakdowns during the coldest nights, but it also ensures your system is running as efficiently as possible—saving you money on monthly energy bills.

3. Seal Air Leaks and Inspect Insulation

Even the best HVAC system can struggle if your home isn’t sealed properly. Drafts around doors, windows, or attic hatches allow warm air to escape, forcing your heating system to work overtime.

Here’s how to tighten up your home for fall:

• Check windows and doors for drafts and seal with caulk or weatherstripping.
• Inspect attic insulation—it should be evenly spread without gaps.
• Look for visible gaps around plumbing and electrical penetrations.

By improving your home’s insulation and sealing leaks, you reduce strain on your HVAC system and keep your family cozy all season long.

Ask R&B Climate about energy-efficient solutions or home comfort upgrades during your fall tune-up.

4. Clean and Clear Outdoor Units

Your outdoor AC condenser has likely collected leaves, grass clippings, and dirt throughout the summer. As fall arrives and leaves start dropping, it’s important to keep your unit clear of debris to maintain proper airflow.

• Tip: Gently rinse your condenser with a garden hose to remove dirt (never use a pressure washer).
• Clear space: Keep at least two feet of clearance around the unit—trim back bushes or plants if needed.
• Prepare for winter: Once it’s time to shut down your AC for the season, consider covering the unit with a breathable cover to protect it from debris and ice.

During your HVAC maintenance service, R&B Climate will clean and inspect your outdoor unit for you, ensuring everything is ready for the off-season.

5. Test Your Furnace or Heating System Early

The last thing you want is to turn on your furnace for the first chilly night in November and realize it doesn’t work. That’s why we recommend testing your heating system early in the fall.

Steps to test your system:

1. Switch your thermostat from “cool” to “heat.”
2. Set the temperature a few degrees higher than the current room temperature.
3. Listen for the furnace to kick on and check that warm air is flowing from the vents.

If you notice strange noises, weak airflow, or unusual odors, it’s time to call a professional. Addressing small issues now prevents costly emergency repairs later.
