🦃 Holiday Mode: How to Prepare Your HVAC System for Thanksgiving and the Holidays

As Thanksgiving approaches, most people focus on prepping the turkey, setting the table, and bracing for Uncle Joe’s stories. But your HVAC system? It’s about to enter holiday mode handling oven heat, packed houses, and fluctuating fall weather, often all in one day.

Knowing how to prepare your HVAC system for Thanksgiving is more important than most homeowners realize. It’s one of the most high-stress days of the year for your heating and cooling system, and if it’s not ready, you could be left with a stuffy house, uneven temperatures, or worse: a breakdown.

Here are our top holiday HVAC tips to keep your home warm, your guests comfortable, and your energy bill under control.

🔥 Why Your HVAC System Works Overtime on Thanksgiving

From long hours of cooking to guests constantly opening and closing doors, your home’s heating system experiences serious stress on Thanksgiving. That sudden increase in thermal load can make it harder for your system to regulate temperature and maintain airflow. More people = more body heat. More cooking = more ambient heat. Frequent door swings = cold drafts. And your system is trying to respond to all of it at once.

Quick tip: Keep interior doors open to improve air circulation, and minimize opening exterior doors. Good airflow helps your system run more efficiently and prevents it from overcompensating.

🦠 Dirty Filters Can Cause HVAC Problems Fast

If your system feels like it’s running non-stop, or rooms are getting too hot or too cold, your air filter could be the culprit.

Clogged filters are one of the top causes of airflow problems during the holidays. They force your HVAC system to work harder, overheat, or cycle on and off more frequently, especially when the system is already under pressure.

👉 Replace your air filter before Thanksgiving, especially if it’s been more than 1-3 months since the last swap. It’s a simple step that can make a big difference in airflow, indoor air quality, and energy efficiency.

📱 Use Smart Thermostats to Manage Comfort During the Holidays

Programmable and smart thermostats are your best friend during big holiday events. They help keep guests comfortable while saving energy, and reduce the need to constantly adjust the heat up or down.

If your system has zoning or smart sensors (like our ArcticFlex systems with “Follow Me” functionality), you can customize temperatures for different rooms or times of day. That means cooler bedrooms, warmer living areas, and no one arguing over the thermostat.

Did You Know?

Smart thermostat use can potentially reduce heating costs by up to 10% annually. (U.S. Environmental Protection Agency [EPA], n.d.)
The ArcticFlex heat pump system delivers 100% of its rated heat capacity down to 4°F without having to use your backup heat. (Blue Ridge Heating & Air, 2025, p. 1)

⚠️ Signs Your Heating System Is Overworked

If you’ve ever thought, “Why is my HVAC running constantly during the holidays?”, it’s not just the extra activity. It’s often a sign of poor airflow, system inefficiency, or lack of maintenance.

Common holiday HVAC red flags:

Loud or unusual noises
Rooms that are too hot or too cold
The furnace or heat pump won’t stop running
A burning smell when the heat kicks on

Don’t ignore these signs! They could mean your system is struggling to keep up, or needs a professional tune-up before winter truly arrives.

🛠️ Schedule HVAC Maintenance Before Winter Hits

One of the best HVAC tips for the holidays? Schedule a fall system checkup before guests arrive.

Routine maintenance can:

Improve system efficiency by up to 30% (EcoWatch, n.d.)
Boost airflow by 10-46% after cleaning the blower (National Air Duct Cleaners Association, 2025)
Prevent up to 95% of major HVAC breakdowns (ABM, 2023)

A clean, tuned-up system works more efficiently, handles stress better, and gives you peace of mind for all winter long, not just Thanksgiving Day.
