How to Transition from A/C to Heat Without Surprises

Simple steps to get your HVAC system ready for fall

As August winds down and cooler nights approach, it’s time to start thinking about switching from air conditioning to heating. But making the seasonal transition without preparing your HVAC system can lead to inefficiency, unexpected breakdowns, and higher energy bills.

At Grille Mechanical, we’ve helped homeowners across New Jersey and Florida smoothly navigate the change of seasons. Here’s a step-by-step guide to ensure your system is ready for the switch—and that you stay comfortable no matter what the weather brings.

1. Schedule a Professional HVAC Inspection

Before you turn on your furnace for the first time, book a seasonal maintenance appointment. A technician can:

• Check for wear and tear on critical components

• Inspect belts, motors, and burners

• Ensure proper airflow and duct performance

• Test safety controls and thermostat accuracy
  

Pro Tip: August is the perfect time to schedule service—before the fall rush begins and appointment slots fill up.

2. Change Your Air Filters

Air filters work hard during the summer months, trapping dust, pollen, and debris. Starting the heating season with a clogged filter can:

• Restrict airflow

• Overwork your blower motor

• Reduce indoor air quality

• Drive up energy costs

Swap in a fresh filter now to protect both your system and your health.

3. Check Your Thermostat Settings

When you switch from cooling to heating, update your thermostat schedule for energy efficiency and comfort:

• Set your thermostat to 68°F when you’re home

• Lower it to 60–65°F when you’re away or sleeping

• If you have a programmable or smart thermostat, adjust your schedule now to match your routine
  

Upgrade Tip: A smart thermostat can help you optimize energy use and manage settings remotely—ask Grille Mechanical about recommended models and available rebates.

4. Clean Around Your HVAC System

After a long summer, your outdoor unit may have collected debris like grass clippings, leaves, or branches. Clear at least 2 feet of space around it to ensure proper airflow.

Inside, make sure your vents are free from furniture, rugs, and obstructions to maintain even heating throughout your home.

5. Test Your Furnace Early

Don’t wait until the first chilly night to discover there’s a problem. Run your heating system now for 10–15 minutes to:

• Check for unusual noises or odors

• Confirm warm air is flowing through all vents

• Identify potential issues before you actually need the heat

If something doesn’t seem right, call for service before temperatures drop.

6. Address Indoor Air Quality Needs

Transitioning seasons often brings humidity changes, dust, and allergens. Consider:

• Installing a humidifier to combat dry winter air

• Adding UV air purifiers or high-efficiency filters

• Cleaning ducts to remove summer buildup
  

Grille Mechanical offers full IAQ solutions to keep your air clean, balanced, and healthy year-round.
