How to Winterize Your HVAC System Before the Thanksgiving Chill Hits

As the festive energy of Thanksgiving approaches in Anaheim, California, families are busy prepping feasts and decorating homes. But before you welcome guests or settle in for a cozy evening, it’s important to prepare one often-overlooked part of your home: your HVAC system. Southern California may not experience frigid winters, but chilly November nights can still test your heating system. Winterizing your HVAC system ensures comfort, efficiency, and helps you avoid inconvenient breakdowns—especially when family and friends are visiting.

While Anaheim, Buena Park, and surrounding Orange County cities enjoy mostly mild winters, unexpected cold snaps can happen—particularly overnight. Efficient HVAC systems keep your home warm without spiking energy bills. Proactive winterization also extends the lifespan of your equipment and reduces the risk of emergency repairs, something no one wants during the holidays.

Below, the expert team at Paul White HVAC walks you through how to prepare your heating, ventilation, and air conditioning system for the coming season:

The best first step is to schedule a routine inspection with a local HVAC professional. In Anaheim, La Palma, and Fullerton, many homeowners wait until something breaks. Instead, preventive maintenance helps identify minor issues before they become costly emergencies.

During a checkup, a qualified technician will:

• Inspect and clean burners, heat exchangers, and blower motors
• Test thermostat accuracy and recalibrate if necessary
• Check for leaks in ductwork or gas lines
• Replace worn belts and lubricate moving parts

Clogged filters are common culprits of system inefficiency. In the dry, dusty climate of Orange County, this is especially relevant.

Make sure to:

• Replace disposable filters monthly
• Clean or replace reusable filters as recommended by the manufacturer
• Not only does this improve indoor air quality, but it also boosts your system’s performance and lowers energy use.

Even the best furnace in Garden Grove or Yorba Linda can’t overcome leaky windows and doors. Sealing drafts keeps your warm air inside and cold air out—maximizing your HVAC’s efficiency.

• Use weatherstripping and door sweeps
• Add insulation to attics and crawl spaces
• Seal duct leaks with mastic or foil tape

Smart or programmable thermostats can save homeowners in Westminster and Whittier up to 10% on heating bills. Set lower temperatures when you’re asleep or away, and program cozy temps for when family and guests are home.

Industry experts recommend at least one professional inspection and maintenance service per year—ideally in the fall to prepare for increased winter use. This is especially critical for older systems in homes across Anaheim, Cypress, and La Habra.

As you tidy up for Thanksgiving, consider these quick wins:

• Vacuum air vents and registers to remove dust
• Make sure furniture doesn’t block air flow
• Stock up on extra filters so you’re ready through winter
