Thanksgiving Guest Prep: HVAC, Water Heater, and IAQ Checklist & Tips

November 5, 2025

Hosting this Thanksgiving? A warm, comfortable home with reliable hot water and clean indoor air can make all the difference for your guests. In Idaho’s dry, chilly November—especially across the Treasure Valley—small tune-ups and smart settings go a long way. Use this practical checklist from No Bogus Heating and Cooling to keep your HVAC, water heater, and indoor air quality running smoothly, without the stress or surprise breakdowns.


HVAC Comfort: Quick Wins Before Guests Arrive


A well-prepped heating system saves energy and prevents mid-dinner hiccups. Focus on these essentials:


  • Replace or clean your furnace filter (every 30–90 days). Restrictive filters drive up energy costs and strain equipment.
  • Set your smart thermostat to 68–70°F during the day; drop to 66–68°F at night. Ovens and extra bodies add heat.
  • Open supply vents and ensure returns aren’t blocked by furniture, decorations, or luggage.
  • Listen and sniff: rattling, whistling, or a persistent burning smell isn’t normal—schedule a furnace tune-up.
  • Test carbon monoxide detectors and replace batteries. Idaho homes rely on gas equipment; safety comes first.


People Also Ask: What thermostat setting is best for Thanksgiving guests?


Aim for 68–70°F while entertaining. With cooking, candles, and a full house, indoor temperatures can rise 2–4 degrees. A slight setback (66–68°F) at night keeps rooms comfortable for sleeping and reduces dry-air symptoms common in our high-desert climate.


Water Heater Readiness: Hot Water Without the Wait


Holiday hosting means more showers, handwashing, and dishes. Keep hot water flowing with a few simple adjustments:


  • Set the tank to 120°F for comfort and safety. Higher temps increase scald risk and energy use.
  • Stagger showers and dishwasher cycles to prevent running the tank dry.
  • Use “vacation” or eco modes only when you’re away; switch back to standard or “performance” mode before guests arrive.
  • If water turns lukewarm fast, your tank may have sediment buildup or a failing element—book a water heater service to restore capacity.
  • Consider a quick inspection of the temperature and pressure relief valve; if it drips or sticks, it needs attention.


Indoor Air Quality: Clean, Fresh, and Holiday-Ready


Thanksgiving cooking, candles, and pets can spike particulates and odors—especially during Boise’s occasional inversion days. Improve IAQ with these tactics:


  • Ventilate while cooking. Use the range hood on high and crack a window briefly to clear VOCs and steam.
  • Run your system’s fan on “circulate” to keep air moving through filters and reduce stuffiness.
  • Maintain 35–45% relative humidity. Idaho’s dry air can dip below 30%—add a whole-home or portable humidifier to help guests breathe easier.
  • Upgrade filters to MERV 11–13 if your system allows; pair with air purifiers for sensitive guests.


If dust keeps returning quickly or you notice musty odors, schedule duct cleaning after the holiday rush to remove buildup and improve airflow.


Avoid Common Holiday HVAC Mistakes


  • Don’t close too many vents to “force” heat into one room—this increases static pressure and can damage your system.
  • Don’t run space heaters on overloaded power strips. Keep them three feet from decor, bedding, and drapes.
  • Don’t ignore short cycling, loud starts, or frequent resets; these are signs your furnace needs professional attention.
